Water-saving Xishui love the water Composition

"Water is the source of life, and we should protect every drop of water." This sentence is true, if there is no water, the earth will dry up; If there is no water, we humans may die of thirst; If there is no water, there will be no our beautiful world. We should cherish every drop of water and every tear of Mother Earth.

There are many students in our school. After class, they ran to the tap, turned it on, and then threw water at others. When you leave, don't turn off the tap and run as fast as you can.

I have done such a "stupid" thing.

Every week, my sister and I play with water. When we turn on the tap, the red triangle on the water meter will turn. The bigger the tap is turned on, the faster the red triangle turns and the more water you pay.

One day, my sister and I are going to play with water again. As soon as my sister turned on the tap, the red triangle in the water meter turned again. My sister saw it and said to herself, "If the water comes out, it would be great if the water meter doesn't go!" I happened to hear this sentence. I thought about it and said, "Sister, if we turn down the tap, the water meter won't work." "Really?" My sister asked in surprise. "Don't believe me, try it yourself." Sister tried it, and it was exactly the same as I said. My sister was happy and surprised and asked, "Who told you that?" "Nobody told me." "Yesterday, I washed my face and didn't turn off the tap. The water dripped out, but the water meter didn't go at all. " I said to her mysteriously. "Good, good, good! Then we will quickly accumulate water. " But when she thought about it, she frowned. Her sister said, "This is too slow!" " ""Never mind, as long as we accumulate from morning till noon, there will be a lot of water? " She greeted him at once and said, "This is called many a mickle makes a mickle." After that, we gave a low knowing laugh.

This "secret" was finally discovered by my father.

We quickly told the "secret" to Dad, thinking that Dad would praise us. Who knows, dad said to us earnestly, "Do you know what you are doing? This is stealing water! " "ah? My sister and I froze. We have all become thieves, so serious! Dad added, "If everyone is like you, who will pay the water bill for the country?"? "! Didn't you steal the country's water? It is said that wasting water should not be! "Hearing my father's thought-provoking words, my sister and I blushed at once. After a while, I suddenly looked up and pointed to the basin of water and said, "Dad, let's hand over this basin of water!" " ""it's not necessary. You can't do it any more. " Dad told us seriously. We answered loudly: "Yes! "

Students, if you are like this, please correct it quickly!

Water is the source of life. We should save every drop of water. ...

Water is one of the important resources for human survival and development, and it is an indispensable and irreplaceable special resource. Without water, there would be no life and no progress of civilization. The water resources in the world are limited, so we can't use water indefinitely. In today's world, with the continuous growth of population and economic development, the demand for fresh water resources is increasing day by day; At the same time, due to unreasonable utilization, the shortage of fresh water resources is increasingly tense.

Historically, China is a country with frequent droughts, known as "nine droughts in ten years". In the historical documents of more than 2200 years, there have been 1300 droughts. China's per capita water resources are only about 2,300 cubic meters, which is about a quarter of the world's per capita water. Water resources in China are not only less per capita, but also unevenly distributed. The basin area north of the Yangtze River accounts for 63.5% of the land area, while water resources account for 19% of the whole country. With the development of society and economy, the gap of water resources is getting bigger and bigger. At present, China's agricultural irrigation lacks more than 30 billion cubic meters of water every year on average, and there are still more than 30 million people in rural areas who have difficulty drinking water. There are more than 400 cities in China that are short of water, and there are more than 1 10 cities that are seriously short of water. The daily water shortage in Chinese cities is160,000 cubic meters, which affects the industrial output value by more than 200 billion yuan every year, and the urban population is about 40 million.

It can be said that through years of efforts, China has made great progress in water conservation, but compared with some developed countries, we still have a long way to go. Agriculture is a big water user and a great waste of water resources. At present, the agricultural irrigation mode of "soil canal water conveyance plus flood irrigation" is still widely used in China. Half of the irrigation water is lost in the water conveyance, and the irrigation water utilization coefficient is mostly only 0.4, which is less than half of that of some developed countries. After irrigation with water per square meter, the grain yield in China increased by 0.5 kg, and that in developed countries could reach 2 kg. Industry, due to the backward technology of existing water facilities, the current water consumption per 10,000 yuan of industrial output value in China is 103 cubic meters, 8 cubic meters in the United States and only 6 cubic meters in Japan, which is 10 ~ 20 times that of developed countries; The reuse rate of industrial water in China is only about 40%, while the average level in developed countries is 75% ~ 85%. It is very serious for urban residents not to pay attention to saving domestic water. Beijing alone leaks 360,000 tons of water every year.

We should learn some good methods from abroad, such as: carrying out "water resources education" to raise people's awareness of water saving, building pipelines to collect sewage from urban residents and public facilities, recycling urban sewage after secondary or tertiary treatment and purification, improving toilet washing equipment and adopting water-saving household equipment, so that we can save water better!

-Presenting gifts to World Environment Day during the Sixth Five-Year Plan period.

Water is the source and foundation of life, and human health comes from water first. People can go without food for several days, but they can't go without water for several days. Now, there are 2 billion people in the world who are seriously short of water! In other words, water is the life of 2 billion people. In the world, 50 million children die every year because of drinking unclean water! How shocking this figure is! The water crisis has sounded the alarm for mankind! Saving water and protecting water resources are the top priority now!

How important water is to us! If everyone pays attention to saving water, I wonder how many people will benefit from it; On the contrary, if everyone wastes water resources carelessly, many people may suffer from drinking water difficulties! For example, some water pipes in public places leak, we can find someone to repair them, but if they are not repaired in time, it will be a waste of our drinking water. However, spilled water will never come back, which is tantamount to wasting water resources. How wrong this is!

Some factories do not pay attention to the protection of water resources, and discharge industrial wastewater into rivers and lakes, causing pollution in many rivers and lakes. However, such a result has to be taken seriously. Fish and shrimp will die if they drink such water; If humans bathe with such water, they will get sick; If humans drink such water, it will be harmful to their health. Water ring devours the health of human beings and animals! Imagine that even if the employees in the factory earn a lot of money, the water is polluted and people have no clean water to drink. So how do they survive? What's the use of asking for such money at that time? How bad it is for others!

Some people have developed a bad habit, that is, they like to throw garbage into rivers, lakes or other inappropriate places at will for convenience. Imagine that if everyone throws garbage into rivers and lakes, a lot of water resources will be polluted; If everyone litters at will, when it rains, the rain will wash the garbage into rivers and lakes, thus polluting the water resources on which we depend. If a lot of water resources are polluted, how can we survive? I think this bad habit is a temporary convenience and a lifelong hazard, which must be eradicated!

Now, because many aspects are polluting water resources, and the pollution is getting more and more serious, human beings can drink less and less water. However, without water, human beings can't survive. This means that we should take active actions to save and protect water resources now. In order to save and protect water resources, I think everyone should put an end to the bad habit of littering casually and throw garbage into the trash can; The uncles and aunts of the factory must resolutely prevent industrial wastewater from flowing into rivers and lakes, and must be treated harmlessly before being discharged; If the water pipe at home leaks, find someone to repair it immediately; To form a good habit of saving water, don't waste water resources casually (such as playing with water guns, washing vegetables and clothes can be used to flush toilets, etc.). ).

Let's join hands to save water and protect water resources! I believe that through the efforts of all of us, we will be able to do it!

Ways to save water

When taking a bath, first use the shower nozzle to get wet from head to toe, then wipe the whole body with soap or shower gel, and finally rinse it off at one time. Wash your face and brush your teeth with washbasins and cups as much as possible, and don't leave the tap on.

The washing machine washes when it is full of clothes. In addition, the last rinse water is reserved for the washing water of the next batch of clothes.

If you think the water tank of the toilet is too big, you can put a coke bottle full of water in the tank, which can reduce the amount of water flushed each time.

Use as much water as possible. Washing dishes and chopsticks with rice washing water and boiled noodles not only removes oil but also saves water; Watering flowers and washing cars with vegetable washing water, laundry water and dish washing water; After washing your face, you can wash your feet and then flush the toilet.

When washing hands, washing in a basin saves more water than running water, and the same is true when washing vegetables and fruits or washing dishes. Continuous washing with the tap on is very water-consuming, and intermittent washing can save water. Save water and reuse it.

The washing machine at home consumes a lot of water. In order to save water, manufacturers and researchers have made great efforts to save water as much as possible on the premise of ensuring the cleanliness of clothes.

This inclined shape is not for beauty or originality, and the inclined plane design of 10 degree has its own reasons. After the washing drum is tilted 10 degree, its water level is relatively deep, which can achieve a large number of washing effects. So save water.

The program set by the washing machine is generally one wash and two rinses, and water is mainly spent on rinsing. If washing powder is not used, won't rinse water be saved?

This ultrasonic washing machine can send out 20,000 shock waves per second, which can "shake" the dirt on clothes. A special water electrolysis device is also installed in the washing machine, which can decompose water molecules in tap water into hydrogen ions and oxygen ions, and use the ions to decompose and adsorb stains and dust to clean clothes. Two-pronged, this washing machine without washing powder saves more than 30% water than ordinary washing machines.

Also, the water level of the washing machine should not be set too high, otherwise there will be no friction between clothes, and it will waste water if it is not cleaned.

In addition to washing machines, toilets are also a major household water user, accounting for about 35% of residents' water consumption. A family of three will wash away more than 3,000 liters of water a month.

Technicians have developed a new type of toilet, which only uses 4 liters of water each time, saving one-third to one-half of the water compared with the existing toilet.

Its water tank accumulates air while filling water, compresses the accumulated air by using the pressure in the water supply pipeline, and then pushes the water to flow into the bedpan at a higher speed. Different from the "pull" force of traditional sanitary ware, this new sanitary ware uses "push" force to discharge dirt, which has great impulse, so it can save water.

In fact, other domestic water can also be used to flush toilets. For example, after the last rinse, the clothes are washed clean, and the water discharged from the washing machine looks cleaner. Unfortunately, it flows directly into the sewer. There is also water such as washing your face and vegetables. It would be nice if it could be reused. Wu Hanping, an amateur inventor, developed a set of domestic water reuse device and obtained a national patent. He connected the sink in the kitchen, the basin in the bathroom and the water tank in the bathroom to a water storage tank. Clean water from the sink and basin enters the storage tank for flushing the toilet.

Now I'll teach you the secret of water saving 1. To use the water-saving toilet, please install a two-stage flushing accessory for the ordinary toilet. 2. Remove the floating cake under the water tank to form a stepless control water outlet.

3. The flushing time of the urinal automatic flusher is shortened. 4. Water the flowers, wash the car and scrub the floor with clean water such as rice washing water, laundry water, dish washing water and bath water. 5. The carpet cleaning method is changed from wet or steam to dry powder. 6. Recycle the water collected by dehumidifier and the wastewater from water purification equipment such as pure water machine and distilled water machine.

Now that I have finished six secret recipes for water saving, have you thought of a better way to save water than me? Are you saving water? I think you should save water!

For a long time, people generally believe that water is "inexhaustible". If you don't know how to cherish it, you will waste it. In fact, water resources are increasingly scarce, and the urban water supply work in our city is struggling on the edge of serious water shortage, and tap water is hard to come by.

People can't live without water for a day. Water is the source of life. Cherishing water means cherishing your own life! Here, we introduce some water-saving common sense in daily life:

Brush your teeth/teeth

Waste: continuous drainage for 30 seconds, using about 6 liters of water.

Water saving: cups are connected with water, 3 cups use 0.6 liters of water. A family of three can save 486 liters of water twice a day.

wash clothes

Waste: The washing machine needs about 165 liters of water each time while filling water.

Water saving: the washing machine adopts the washing-dehydration-water injection-dehydration-water injection-dehydration mode, and the water consumption is 1 10 liter each time, which can save 55 liters and 220 liters each time.

In addition, centralized laundry can reduce the number of laundry; Hand washing is advocated for small pieces and a small amount of clothes, which can save a lot of water; Too much detergent will waste a lot of water.

have a bath

Waste: A long uninterrupted water shower will waste a lot of water.

Too much bath water, or even overflow, or open the water plug and inject water at the same time, the waste will be amazing.

Water saving: intermittent water shower (such as pedaling, induction, etc.). ). Turn off the water in time when scrubbing. Avoid taking a long shower.

The water after bathing can be used for washing clothes, washing cars, flushing toilets and mopping floors.

cook

Waste: the tap was left on for a long time. Boiling water for too long, a lot of water vapor evaporates. Rinse vegetables and fruits with tap water.

Water saving: oil stains on cookware and tableware can be wiped off with paper before washing, which can save water.

Control the flow of the faucet, and change the uninterrupted flushing into intermittent flushing.

wash a car

Waste: Rinse with water pipe for 20 minutes and use about 240 liters of water.

Water saving: 3 barrels of water are needed for car washing, and the water consumption is about 30 liters. Wash the car with car wash water and car wash water. Rinse with a water-saving spray gun. Use mechanical automatic car washing, car washing water treatment recycling.

Small ways to save water:

Saving water is beneficial to the present and will make great contributions to the future. After discussion, the students came up with some ways to save water in life:

1. Washing vegetables with rice-washing water and then with clear water not only saves water, but also effectively removes pesticide residues on vegetables;

Second, wash the mop, sweep the floor, and then flush the toilet. The second washing water for washing clothes cleans doors and windows, furniture, shoes and socks, etc.

Third, flush the toilet after urinating, try not to open the big water pipe for flushing, and make full use of the used "dirty water";

4. Sprinkle water on the indoor and outdoor ground in summer to cool down, try not to use clear water, and use washing water after washing;

5. When cleaning bicycles and family cars, don't rinse them with water, but wipe them with a damp cloth. If it is too dirty, wash it with the water left over from washing clothes.

6. Flushing the toilet: If you use water-saving equipment, you can save 4-5 kilograms of water each time;

Seven, family watering flowers, appropriate use Taomi water, tea, laundry water, etc. ;

Eight, household washing towels, small objects, fruits and other small amounts of water. It is advisable to use a basin to hold water instead of turning on the tap to flush;

9. Washing the floor: scrubbing with a mop can save more than 200 kilograms of water than washing each household with a faucet;

Ten, faucet used for a long time leaks. You can cut open the rubber cover of the small bottle containing penicillin to ensure no water leakage;

1 1. Adjust the floating ball in the toilet water tank down by 2 cm, saving nearly 3 kg of water each time; If you use it four times a day at home, you can save 4380kg of medicine a year.

Twelve, washing vegetables: a pot of a pot, do not run the faucet, a meal can save 50kg；;

13. Shower: If you turn off the tap to wipe soap, you can save 60kg of water by taking a shower;

14. Hand-washing clothes: If you use the washbasin to wash clothes, you will save 200kg of water each time compared with turning on the tap;

15. Washing clothes with a washing machine: I suggest you fill a bucket before washing. If washed twice separately, it will consume120kg; More water.

Sixteen, car washing: scrubbing with a rag can save at least 400kg. Compared with washing with a faucet, the water consumption is much less each time;

Cherish water resources

Zhaoqing 16 th primary school

Platform for action

Water, the source of life, is the place where 10 trillion lives depend. People keep wasting water resources, but few people do. Although nearly 5∕9 of the earth is covered with water, 97% of it is inedible seawater, and the remaining 3% of fresh water is only 1∕3 for drinking. This shows how precious water is.

introduce

"Water is the source of life, and we should protect every drop of water." This sentence is true, if there is no water, the earth will dry up; If there is no water, we humans may die of thirst; If there is no water, there will be no our beautiful world. We should cherish every drop of water and every tear of Mother Earth.

We can't wash our faces, brush our teeth and quench our thirst without water. There are no fish, shrimp, flowers and trees on the dining table. We don't know what swimming is. All boats and boats are scrapped, concrete can't stop, tall buildings can't be built, and even little dolls can't cry ... In short, water is very precious. But there are often many people who don't know how to cherish. The faucet spouts water, but people don't know where to go; Pour a jar of water into the bathtub, soak it for ten minutes, and then let the water run away. ...

So our science and technology group decided to investigate and analyze, write a paper, and call on everyone to save water and protect water resources.

1. Investigation and analysis on the total water consumption of Guangdong residents.

The water use habits of most of us in Guangdong can be summed up in two words-waste. It is reported that in 2007, the comprehensive water consumption per capita in Guangdong Province was 493 cubic meters, while in 2007, the comprehensive water consumption per capita in China was only 438 cubic meters. In the impression of ordinary people, Guangdong is located at the southernmost tip of Chinese mainland, with abundant rainfall and abundant water resources. Therefore, Guangdong people have long developed the habit of using water without worry and using it whenever they want. Agricultural, industrial and urban domestic water is seriously wasted. The water quota of various industries is generally higher than that of other provinces. But the actual amount of water resources is not high. According to reports, at present, the per capita water resources in Guangdong are 2 1 18 cubic meters, which is less than the national average of 2,200 cubic meters and only equivalent to a quarter of the world's per capita water resources. In recent years, the frequency of drought and water shortage is obviously higher than before, especially in coastal areas. When suffering from drought, salt tide disasters often use the river water level to drop. Therefore, the shortage of water resources has become an important restrictive factor for Guangdong to achieve the goal of a well-off society in an all-round way and the sustained and rapid economic development in the next 20 years.

Similarly, there is a waste of water that we all often do. Now, we see that many stores use sterilized plastic wrap tableware for customers, but some diners habitually rinse with hot tea before using it. This is a waste of water. From the point of view of saving water, this habit is a great waste. If a glass of water is 1/8 liters, 8 customers use 1 liter, 8,000 customers are 1 ton of water, that is, 1 cubic meter of water, and 80,000 customers are1cubic meter of water. According to the statistics of permanent population and floating population in Guangzhou at the beginning of last year, it has reached120,000. Roughly speaking, if everyone goes to a restaurant once a day, the water for washing dishes alone will be wasted 1500 cubic meters, which is 547,500 cubic meters a year.

Of course, Cantonese people gradually know how to save. He Guoqing, deputy director of Guangdong Hydrology Bureau, and other experts talked about building a water-saving society at a water use activity on June 1 1, and thought that Guangdong had great water-saving potential and broad prospects. The first is the potential of industrial water saving. At present, Guangdong's industrial water intake quota is high, the reuse rate is low and the leakage is serious. The reuse rate of industrial water in China is about 55%, while that in developed countries is 75%~85%. The recycling rate in Guangdong is generally only 20%~40%. Therefore, experts believe that industrial water-saving channels are mainly to strengthen water-saving work in key industries such as thermal power generation, chemical industry, paper making, metallurgy, textile, building materials and food. Secondly, the agricultural water-saving potential, the utilization rate of agricultural irrigation water in the province is only about 40%, while in advanced countries it reaches 70% ~ 80%; The area of water-saving irrigation projects in Guangdong accounts for less than 1/3 of the effective irrigation area, and the canal seepage prevention rate is low, especially in irrigation areas with advanced water-saving measures such as sprinkler irrigation and drip irrigation. Experts believe that there is also much to be done in this regard.

Three, the investigation and analysis of common wastewater situation

1, due to the backward management level and low economic strength, advanced water conservancy technology, equipment, technology and management methods can be adopted instead. For example, farmers in many parts of our country still hold the old idea of flooding and filling the whole field with water when watering the land. In some places, it takes 1 ton of water to produce one kilogram of rice. In addition, China's production technology is backward, industrial production water demand is huge, water reuse rate is low, and water consumption is large.

2. The maintenance and replacement of water-saving equipment and facilities are not timely, resulting in waste of water resources. For example, due to years of disrepair, urban water supply pipelines leak water during water delivery; Due to negligence, the manager forgot to turn off the tap; The household faucet is not closed tightly, causing water leakage, and so on.

3. Waste is caused by not using water-saving facilities or water-saving devices. Some people are reluctant to replace water-saving appliances, but in fact, the extra water fee is enough to buy water-saving appliances. Nowadays, there are more and more kinds of water-saving appliances. Take the toilet as an example. Compared with water-saving toilets, old toilets waste 4-5 kilograms of water at a time and 3-25 tons of water a month. If there are 200,000 toilets, 500 million tons of water will be lost a year.

4. The water-saving system is not perfect, the management level is low, and the implementation is weak. Some water users have exploited the loopholes of the system, resulting in the waste of water resources.

People's weak consciousness of saving water is the most fundamental reason for wasting water. If each of us pays a little attention, we can save at least 1 kg of water every day.

It is not surprising that water is wasted in the family. Some people like to turn on the tap and wash it for a long time when using water, which wastes a lot of water. It is also common for some people to waste water when they store it. But humans can't realize how many precious lives they call "liking the new and hating the old" will cost the earth.

7. In schools, wasting water is more common. Usually, some students always forget to turn off the tap after using water; When you take a shower, you wash crazily for a moment's pleasure. My negligence not only brought inconvenience to others, but also brought consequences to me. During the shower peak period, water supply often stops. But that's all. Why is this happening? After investigation, our school uses a lot of water and wastes a lot. Boys' dormitories are often short of water, which may have serious consequences in the long run.

8. In agriculture, water resources are also seriously wasted. According to the data, 2004 was the worst drought in 26 years, and it was difficult to have a rain. By the first half of February this year, the drought-affected area of crops in the province was as high as 271870,000 mu, accounting for 43.34% of the cultivated land area. 29 16000 people and 1 12800 large livestock have difficulty drinking water. However, in most areas, water conservancy is still arbitrarily opened and irrationally irrigated.

Faced with this situation, do humans have the heart to treat the liquid of life like this? Have the heart to let this beautiful water polo dry up? Are you willing to turn a blind eye like this? Therefore, let's look for water-saving strategies together.

Four. Measures and suggestions

(1) water-saving methods and measures

① Bathroom water

1. Shower can save at least 50% water consumption, about 50 liters, compared with bath.

2. Using low-flow shower heads, such as installing "water saver" on shower heads, can not only save 50% of water consumption, but also save energy consumption of water heaters.

Don't pour out the water after taking a bath, but use it to flush the toilet, wash clothes, water flowers, etc.

4. When adding water, prevent water from overflowing or losing.

5. Water-saving device of faucet can be installed.

6. Develop the good habit of turning off the faucet at any time without using water, and check whether the faucet is completely turned off before going to bed or when leaving home.

②. Sanitary water

1. Bottles of appropriate size can be placed in the toilet box to reduce water consumption.

2. Adjust the height of the floating ball to control the water output.

3. Flush the toilet with other stored water.

4. Install a water-saving toilet, or add two-stage flushing accessories to the existing ordinary toilet.

Please repair the toilet and water tank as soon as possible.

6. Don't throw paper towels and other items into the toilet to increase water consumption.

③ Laundry water

1. Control the amount of clothes and avoid too many or too few washing machines.

2. When cleaning for the first time, water is only removed once before cleaning, which can save water and cleaning time.

3. Choose the appropriate laundry time according to the type of clothes.

④ Reuse of water

1. Don't flush the faucet directly when washing dishes, vegetables and clothes. Instead, put an appropriate amount of water in the basin to reduce water consumption.

2. The water for washing rice and cooking noodles can be used for washing dishes and chopsticks.

3. Vegetable washing water, laundry water, dish washing water and bath water can be used for watering flowers, washing cars and scrubbing floors.

4. The water collected by dehumidifier and the wastewater from water purification equipment such as water purifier and distilled water machine can be recycled.

The food to be thawed can be taken out of the refrigerator as soon as possible, or thawed in the microwave oven to reduce the water consumption.
