Composition of visiting sewage treatment plant
On Monday afternoon, teachers and students of our class visited Xinyuan Sewage Treatment Plant. At this time, I really can't wait to see how the black sewage will be treated before it becomes clear water. I walked into the sewage treatment plant with doubts in my heart.
We lined up neatly, and under the leadership of the staff, I was stunned by the foul, dark and dirty water.
Then, we went to the "yarn separation" system, which can separate large objects, and the separated water enters the biochemical pool for "microbial" treatment. If there are still many microorganisms, send them to the dehydration room for dehydration. At this time, when the water in the biochemical pool flows into the sedimentation tank, the sound is deafening, but the smell of the water is still very strong. On the way to the "sedimentation tank", the water at the foot of the pond flows downwards, which makes people feel scared.
We soon came to the "sedimentation tank" and saw clear water above and sludge below. The water finally flows into the "disinfection pool" for ultraviolet disinfection, and then can be discharged into the outlet pool.
On the way back, I mused: water is an important substance for human survival, so we must cherish every drop of water. Although I can't stop too many things that damage the environment, I can start from myself and start from the little things around me to do my part to protect water resources.
Visiting the Sewage Treatment Plant Composition 2 Today, my father and I got up very early, because today I will take part in the activities of a small reporter. Looking at the sunny weather outside the window, I am very excited.
Our reporter's activity this time is to visit Longquan Sewage Treatment Plant in Zhuzhou City to learn how urban sewage is treated. It takes us about twenty minutes to get to our destination by car. Walking to the door of Longquan Sewage Treatment Plant, I saw a tall building with sixteen Chinese characters, which read "Realistic and innovative, harmonious development, green humanity, pollution control and water purification", which was very eye-catching. I can't wait to know
Under the leadership of the teacher and Uncle Miao, we started today's visit. Uncle Miao never forgot to remind us to "pay attention to safety" during the visit, because there are many machines and pools here, and it will be dangerous if we are not careful. Throughout the morning, we visited the water inlet, grit chamber, biochemical tank, MBR tank and ultraviolet disinfection tank of the sewage treatment plant. Each pool has a different function. Through Uncle Miao's explanation, I know that it can treat about 200,000 tons of sewage every day and has more than 30 staff. Dirty and smelly sewage will turn into clear water after being treated by these pools every day, and then it will be discharged into Xiangjiang River from Jianning Port, ensuring the water quality of our mother river.
Through today's visit, I know that urban sewage is treated in this way. After many processes, sewage can also be turned into our domestic water. This little reporter activity is very interesting and meaningful. I hope I can attend next time!
This morning, our class carried out social practice activities and organized everyone to visit the sewage treatment plant.
Early in the morning, the students gathered at the school gate early, and we lined up to board the bus bound for Xinxicun Village in Tieshan Town. When all the people arrived, the vehicles slowly drove to the suburbs, and the tall buildings passed by the window. Soon, we arrived at our destination.
As soon as the coach entered the sewage treatment plant, I was shocked by everything in front of me! A neat house, with neatly trimmed turf in front and back. Ah! What a beautiful sewage treatment plant! I thought the sewage treatment plant was dirty! It is far from what I expected.
After getting off the bus, we lined up, and my uncle in the factory showed us around the sewage treatment plant. While visiting, we listened attentively to my uncle's introduction: "Our factory is located in Xinxi Village, Tieshan Town, a suburb. It has been built and put into operation for 6 years. For 7 years, it can treat hundreds of tons of sewage every day. " I was very surprised to hear this explanation.
Then my uncle took us to the computer room where they worked, where there were aerated grit chambers, sedimentation tanks and many machines. The internal fine grid fence and coarse grid fence are used to filter all kinds of sundries and pretreat wastewater; Biological pool is to treat wastewater by biological and chemical principles to reduce various harmful substances in wastewater; The water in the pool on the second floor can be directly discharged into Jinlong River after being treated.
After the visit, we went back to the office building and read the relevant information of the sewage treatment plant posted on the first floor.
Ah! Uncle and aunt of sewage treatment plant, you are beauticians of the environment. With your hard-working hands, you have turned the sewage in our life into a clear river and created a beautiful environment for our life. You have worked hard, and we thank you!
It was cool yesterday, and a little white clouds floated across the sky. With a happy mood, Angel reporter and I drove to the sewage treatment plant.
First visit the sewage treatment exhibition hall. The knowledge about water resources and the propaganda of sewage treatment projects are hung on the wall of the hall, which is lifelike. Today's commentator is Master Tang. He vividly introduced the CAST reactor treatment device, which is a miniature model of the sewage treatment plant, and can oxygenate the water.
Next, when we enter the sewage treatment plant, the first thing we see is the coarse grille, which can clean up the garbage over 20 mm, "Oh! So there is a lot of rubbish on the coarse grille, "I cried. "yes". Master Tang said as he led us forward. It stinks all the way, so I have to cover my nose and come to the pumping pit. The depth of the pump pit is 1 1m, and high voltage current can be used to lift water to the pump house. Then use a fine grid to remove 2MM of garbage, and then the sewage enters the biochemical pool for oxygenation, precipitation and effluent. Finally discharged into the Oujiang River. The settled sludge is compressed and dried by the machine and sent to Longwan Binhai for incineration and power generation.
How amazing the sewage treatment plant is! Domestic water for every household and wastewater discharged from factories are collected through the urban management network, and the treated waste is turned into treasure. When I grow up, I will invent a more magical machine to better protect our environment.
On Tuesday afternoon, the teacher took a reporter from Class 6, Grade 3 to visit Xiangxiang Sewage Treatment Plant. On arrival, the teacher asked us a question: What procedure does sewage have to go through before it can become clean water? We came to the sewage treatment plant with curiosity. The environment here is beautiful and clean. Manager Zhou took us to the conference room. He introduced us some basic information about the factory: the sewage plant built with an investment of10.20 billion yuan can produce 25,000 tons of sewage every day. The students were amazed at its factory capacity.
The technician of the factory showed us around the sewage treatment plant. He told us that the sewage first passes through the coarse grille and the new grille to remove impurities in the water, and then passes through the cyclone desander to filter the sediment, so that the water flowing out will be clear, and then after ultraviolet disinfection, the water will be clean and can be safely discharged into the mother river.
In the past, there was a layer of garbage floating in Lianshui River. The river is dirty and people's awareness of environmental protection is poor. Garbage is poured into the river, and the sewage from the factory is directly discharged into the river without treatment, which seriously pollutes the environment and seriously affects people's health. Since the sewage treatment plant, the river is clear and no garbage can be seen anymore. The sewage from the factory comes to the sewage treatment plant and is discharged after purification. This river is also a good place for people to swim in summer. This is all because of the sewage treatment plant!
After the visit, it made me understand that if everyone has good environmental awareness and protects our environment and our mother river, the world will be better!
Visiting the Sewage Treatment Plant Composition 6 Today, our small reporter group visited the Chengbei Sewage Treatment Plant.
As soon as we got there, a big machine appeared in front of us. My uncle told us that this huge machine is called Yingtaishan, which is used to clean up the garbage in the water. Besides, I found a strange place. In a room, there is a long machine like a big comb, but it is much bigger than a comb, and there are headaches on it-plastic bags and so on. My uncle told me it was used to clean up bigger garbage. Then we arrived at the second stop-cyclone grit chamber, which is a pool where sand sinks. Then we came to the third stop, which is called hydrolytic acidification pool. One corner of the pool is covered with duckweed. My uncle said that these duckweeds can help us purify sewage. Later, we passed the aeration tank, oxidation tank and so on, and they all played different roles.
Finally, we went into the comprehensive building and watched the propaganda film inside, especially when I saw a small water drop break down into more than a dozen small water drops, I was very surprised.
When I came out of the sewage treatment plant, I was thinking that if people were not so selfish, they would make less garbage, stop discharging sewage indiscriminately, protect our surrounding environment and give us a beautiful nature. No sewage treatment is needed.
A visit to a sewage treatment plant is 70,000 Li clear, breezy and cloudless in Wan Li. It's a good day to travel. Pack your bags, get on the "special car", enjoy the wild scenery on the hillside all the way, and forget everything else.
At the destination-Kaihua County Sewage Treatment Plant, I followed the teacher's footsteps and broke into the factory. We first watched the first process of sewage treatment-filtering garbage. That is, the sewage flowing out of the city filters out some larger garbage through the coarse grid, and then filters out smaller garbage through the fine grid. The filtered garbage is much cleaner than the original sewage, and I have to marvel at the magic of this sewage treatment plant.
Then, the technician uncle led us to the treatment site of the second process-sedimentation tank. As the name suggests, impurities that cannot be filtered by the coarse grid precipitate and separate from water. As soon as we saw four pools, the water in each pool smelled a little.
I feel guilty when I think that the water is dirty and smelly because we usually don't pay attention to environmental protection and throw garbage into the river at will. In the future, I must protect the ecological environment, don't throw rubbish at will, and make my hometown clean and beautiful again.
Finally, we went to the outlet and watched piles of clear water flow into the river, which made me feel better. Today witnessed the whole process of sewage turning into clear water. The only drawback is that water can't be drunk! However, I believe that in the near future, sewage can not only become clear water, but also become drinking water!
On the way home, the sun seems brighter, and even the wildflowers on the roadside look better!
A few days ago, we visited the sewage treatment plant in Shinan District of Ningbo!
When we entered the scene, a foul smell came to our nostrils, and we couldn't help covering our noses with our hands. Needless to say, this is the entrance of sewage and the first checkpoint of sewage treatment. Here, Cugoshan is "welcoming" sewage. They are like guardians who selflessly intercept larger garbage (such as plastic bags and leaves). Next, the water inlet pump continuously sucks in the sewage, and the sewage will obediently "reform" in the grit chamber!
The second stage of treatment is that sewage enters the biological reaction tank. In a huge circular pool, all kinds of microorganisms will regard pollutants in sewage as their own delicious meal. At this time, although the sewage is still yellow, the water quality has been purified. Then the sewage will enter the secondary sedimentation tank, where they will "reflect on themselves" for about 13 hours, and the granular small garbage will "consciously" settle down, and the sewage will gradually become clean.
The last level is ultraviolet disinfection, and the commentator uncle brought up a small bucket of treated water. "Wow, it's clean!" "We shouted with one voice! The treated sewage can be directly discharged into Fenghua River!
The machines here work 24 hours a day, so the machines must be very tired, too! Therefore, children, we should save water, reduce sewage and protect the environment!
On Sunday, it was clear in Wan Li, Wan Li. We spent ten years together visiting Qingjiang Sewage Treatment Plant.
As soon as I entered the door, I smelled a bad smell. At the first stop, we saw the anaerobic pool. The water in the anaerobic pool is bubbling and stinking. This smell really makes me want to vomit. We also saw a basin of water, because it was all caused by people throwing garbage into the water, which made the water near the water very dirty and smelly. The second stop is called coarse grid well, which contains a lot of garbage and bugs. At the third stop, we came to the fine grid well. The function of this station is very similar to that of the last one. Coarse grid wells filter out slightly larger garbage in sewage, and fine grid wells filter out smaller garbage. The fourth stop is the aerobic pool, where garbage is transported by chain block and submersible mixer. Then there is sewage in the secondary sedimentation tank and the secondary sedimentation tank, but the water is much cleaner than the previous stations, but you can still see a lot of soil. Behind it is the final dosing sedimentation tank to clean the edge of dosing sewage, and finally, the clear water tank to discharge dosing sewage, garbage and insects. After a series of sewage purification, the sewage becomes clean and clear.
Today, I visited the sewage treatment plant. I not only learned knowledge, but also let us know that there is only one earth. We should cherish it, cherish it, do not litter, do not create pollution, care for water and protect the environment.
Visiting the composition of sewage treatment plant 10 Last Sunday, our Bai Yue team went to Central Park and Yueqing Bay to observe the water pollution. We went to Central Park first. As soon as we entered the park gate, we saw a small river with many small fish in it. Suddenly, we saw a dead fish. The fish was dressed in red, floating on the river, half exposed. This is such a beautiful park that we are all in a bad mood. Further on, I saw another big river. There is a sign by the river with many sentences about protecting the environment written on it. Along the river, we observed the river in Central Park, took photos, recorded the water pollution in the river, and wondered why people didn't protect the river. The second step is to go to Yueqing Bay and continue to observe. We came to the dam and saw a wooden bridge. There is a lot of soft soil behind the wooden bridge. Looking to the left, there is a sea of Wang Yang. There are too many mussels on the roadside, some buried in the soil, and some piled up into hills. I think these are all fished out of the sea! Suddenly, a lot of rubbish appeared in front of us. Garbage smells bad. I just want to avoid it. I can't help feeling sorry for the sea.
After observing Central Park and Yueqing Bay, we discussed that most of these pollutions come from ourselves, so I really hope that people can protect the environment, and I hope that the water in the future will be cleaner than it is now!
A visit to a sewage treatment plant composition 1 1 "If we don't cherish water, the last drop of water in the world will be a human tear." After our sixth-grade teachers and students visited Wujin Sewage Treatment Plant together, I was deeply moved by this sentence.
The sewage treatment plant is located in Renmin East Road, Wujin High-tech Development Zone, with a service area of 45 square kilometers and a service population of nearly 450,000. Centralized treatment of urban sewage in the west of Cailing Port, east of Yancheng Road, north of Wu Nan, south of Changzhou City and west of Hutang Town, University Town and High-tech Zone.
First, the main control room of the sewage treatment plant is its "heart", and all the monitoring of sewage treatment is here. You can see the whole process of sewage treatment here. Teacher Wu said, "This is a schematic diagram of sewage treatment process ... The first two computers have been monitoring the operation of sewage treatment ..." With teacher Wu's detailed explanation, I have long wanted to see the most important link-grit chamber.
The grit chamber is used to precipitate larger inorganic particles and discharge them into the anaerobic ditch. There is little oxygen in the anaerobic ditch, which can make microbial cells multiply quickly and fight microorganisms. The teacher pointed to the big things floating on the pool and said to us: "Students, if you look carefully, you will find that there are turbid tiny objects floating on the oxygen ditch, which are the bodies left by microorganisms in the process of" fighting "with organophosphorus and nitrogen. Hearing this, the students were very surprised.
After a thrilling "battle", clean water flowed into the ultraviolet disinfection pool. After ultraviolet disinfection, the water will meet the discharge standard and can be discharged into Cailing Port. From sewage that can be used as ink to extremely clean water, this is really a magical process!
After this visit, I understand that we should produce as little domestic sewage as possible in our lives and make contributions to protecting the earth's homeland.
Visiting the sewage treatment plant composition 12 There is a lot of garbage on our earth, and our small reporter from Class 252 is cleaning up the sewage treatment plant together.
The big troops set off, laughing and laughing all the way, chasing after each other, some students enjoyed the scenery by the river, some were eating snacks, and some were running in the competition ... The male students were so excited that they really wanted to go there as soon as possible, regardless of a drop of dew.
A breeze blew, thousands of green willows blew, and peach blossoms and cherry blossoms laughed. What a picture this scenery looks like! Birds in the sky are greeting us and the sun is smiling at us.
When I got there, I couldn't help covering my nose as soon as I entered the door. We know how sewage is removed. As we walked, we said, I was surprised to see the water in the opposite pool, and said, Ah, how did the smelly water become such clear water? I don't understand, countless small fish are drilling around in my mind, and the river is crystal clear, like waves sprayed by two dragons. We passed many sewage tourist areas, and the most unforgettable one was the wooden bridge. There is clean and clear water under the wooden bridge. As soon as we step on it, we will tremble with tension.
Looking forward to, finally looking forward to the question session. Everyone asks questions to uncles and aunts, just like a little reporter, asking questions all the time. How time flies! We have to go back to school, and everyone doesn't want to leave.
Through this visit to the sewage treatment plant, I understand the truth that there is only one earth, and we should take good care of it. Water resources are precious, so we must save water.
Visiting the Sewage Treatment Plant Composition 13 On a sunny day, the teacher took a group of lively and lovely "rabbits" for a walk on the river bank of the park. Who are these rabbits? It's our classmate in Class 252! The teacher is taking us to the sewage treatment plant.
We talked and laughed all the way, and when we saw a lot of rubbish, we picked up the rubbish on the road with our own garbage bags and bagged it. In a blink of an eye, I arrived at the long-awaited sewage treatment plant. Ah, looking around, many machines are in front of us, surrounded by green grass and red flowers, large and small, so beautiful! We walked up the stairs. Ah, there's a lot of sewage. Some sewage is oily, some water is full of rubbish, and some give off a disgusting and unpleasant smell. We don't want to move forward. This is a huge machine that makes sewage roll in the pool. What happened? After listening to my uncle and aunt's explanation, I realized that this machine can increase oxygen, promote the growth of microorganisms, and let microorganisms eat harmful bacteria in the water, so that there are no bacteria in the sewage. Although there are no bacteria in the sewage, it is still smelly and dirty. Under the guidance of the teacher, we came to another machine. This time, we didn't come to see the machine, but to see the garbage under the net next to the machine. There is a mountain of rubbish under the net. Clean water is like a big mirror, which can't be compared with those sewage. The water coming out of the two big holes is clean without any stains. Clean water will flow into Lianshui River. The teacher took us to the drain, and the white waves lapped the water and hugged my mother. Time is up, we have to go, Yi still left the sewage treatment plant.
Here, I appeal to you not to litter, but to protect the environment. One earth is enough, one ocean is enough, and what is not enough is the environment.
Visiting the sewage treatment plant composition 14 Today, Miss Li organized us to visit the sewage treatment plant.
I am very happy to participate in group activities with my classmates. I talked and laughed with my classmates all the way, but when I arrived at the sewage treatment plant, I smelled an unpleasant smell and frowned.
The staff showed us around and explained the whole process of sewage treatment.
The staff sister led us to the first process of sewage treatment-intercepting well.
We saw piles of sludge on the trolley, and an unpleasant smell came on our faces. My sister told us that clothes, plastic bottles and other wastes that people salvaged from the intercepting well were thrown into the river. My heart sank. Yes, we didn't pay attention in our daily life. We really shouldn't litter at will. Later, my sister explained to us the specific functions of coarse grid, fine grid, oxidation ditch and secondary sedimentation tank. ...
The activity is over, but my heart can't be calm for a long time, which reminds me of the river next to our school. Dad said it was a clear river when I was a child. They often play by the river, but now the river has become a stinking ditch.
This is because not only industrial wastewater is discharged here, but also people living nearby throw domestic garbage and construction garbage here for convenience, and our river has become what it is today.
We say "I want to protect the environment" all day, but it's no use just talking without doing it. Let's take practical actions and start with the little things around us.
In order to keep the river clear, to make the sky bluer, and to give animals and plants a new home to live on, let's "contribute to environmental protection" together.
Visiting the sewage treatment plant composition 15 came to school earlier today, because our school is going to visit the sewage treatment plant today. Under the leadership of teacher Wan, we came to Liuwei Sewage Treatment Plant.
As soon as the bus entered the sewage treatment plant, everything in front of me surprised me: a neat house with neatly trimmed lawns in front and behind. I thought the sewage treatment plant would be messy and dirty, but I didn't expect it to be so much worse than I thought. After getting off the bus, we lined up and were shown around by our uncles and aunts in the factory. We took notes while listening to their explanations.
First, we visited the collecting well. According to my uncle, this collecting well is 10 meter deep! Then we came to the machine room of the magnetic suspension blower and learned that the blower is equivalent to a machine that delivers oxygen to microorganisms. There are many microorganisms in sewage. Finally, we came to the biological pond, the secondary sedimentation pond and the water distribution well. The biological pool is named because there are many microorganisms in this pool. Its function is to treat wastewater by biology and reduce all kinds of harmful substances in wastewater. After passing through the secondary sedimentation tank, the purified water can be directly discharged into the Grand Canal.
After the visit, I want to say to my uncle and aunt in the sewage treatment plant, "You have worked hard! You are environmental beauticians. Without your's efforts, the sewage in our life would certainly be unable to be treated, and the last drop of water in our world would be our tears. Thank you! "
