Methods and measures of domestic water-saving technology?

The methods and measures of domestic water-saving technology are very important. It is very important to understand the methods and measures and solve problems according to the actual situation. Zhong Da Consulting will discuss with you the methods and measures of domestic water-saving technology.

Domestic water saving At present, the main water saving measures are:

1, water meter installation and metering.

2. Use water-saving appliances, including water-saving nozzles, water-saving toilets, water-saving toilet systems, water-saving toilet flush valves, water-saving showers, water-saving washing machines, etc.

3. Urban water-saving irrigation. With the improvement of people's living standards, urban greening area is increasing, and urban irrigation water consumption is increasing year by year. At present, China focuses on popularizing new technologies such as sprinkler irrigation, micro-sprinkler irrigation and drip irrigation, which saves water by 30% ~ 50% compared with the original surface irrigation and saves a lot of labor.

4. Urban sewage recycling technology (reclaimed water technology). Through sewage reuse, the urban water consumption can be increased by more than 50% without changing the existing water supply. The practical experience at home and abroad shows that the recycling of urban sewage is one of the effective ways to reduce expenditure, reduce water pollution, improve ecological environment and solve urban water shortage, which is not only technically feasible, but also economical and reasonable.

5. Reduce the leakage rate of pipe network. Leakage of water supply network is an important aspect of water loss in urban water supply process. Because of the old urban pipe network and serious leakage, it will not only cause the loss of water resources, but also cause safety accidents to the geological environment.

6. Use price lever to adjust water price and promote water saving. According to the Measures for the Administration of Urban Water Supply Price and related regulations, the urban water supply price will be adjusted reasonably, and the price will be increased progressively on the premise of meeting the basic water demand of residents, so as to encourage residents to choose water-saving appliances and sewage reuse.

7. Water saving cap

The water-saving cap is a new type of water-saving pipe fitting, which can be connected with all kinds of high, medium and low-grade mixing valves and faucets through threads, and can easily enter thousands of households and all places where water needs to be saved. Under the joint action of water pressure and fluid continuity principle, tap water becomes a high-speed jet with great kinetic energy and momentum, which automatically changes the function and flushing mode of faucets and saves water for all faucets quickly.

8. Water-saving toilet

New houses and buildings in public places use toilets or pedal squatting toilets with flushing water tanks less than 6L, and non-contact control switch devices are popularized in urinals. Cancel the fittings of sanitary ware water tank with water inlet below the water surface, the fittings of toilet water tank with straight upward drop, and the toilets and water tanks with flushing volume greater than 6L.

9, water-saving shower nozzle

When the traditional shower takes a bath, the common flow rate is above 10 ~ 12l/min. If the bath time is l0min per person, the average person needs 100 l 45℃ water every time. When using water-saving shower heads, because the optimal flow rate is between 3.5 and 4.5 L/min, most people use 4 to 5 L of water at 45℃ at a time.

10, water saving in public buildings

Circulating cooling water system should be adopted in air conditioning of public buildings. With the rapid development of urbanization and service industry, the water consumption of public buildings will increase. Air conditioning system should be regarded as one of the key points of water saving in public buildings. The circulation rate of air conditioning cooling water should reach more than 98%, and the concentration multiple of open system cooling water should not be less than 3. Circulating cooling water system can adopt open or closed circulating cooling water system according to specific conditions.

1 1, public water supply enterprises use water and save water.

The water saving of urban public water supply enterprises is mainly the reuse of backwashing water, which has the dual effects of urban water saving and water environment protection.

Advanced backwashing technology should be actively adopted in reconstruction and new water supply projects. By reforming and strengthening the structure and organization of backwashing system, adopting appropriate backwashing methods, the regeneration function of filter backwashing is improved, and the periodic backwashing technology of high-intensity water is eliminated.

12, leak detection and seepage control technology of urban water supply network

At present, the serious leakage of urban water supply network has become a prominent problem in urban water supply. It is not only an important technical measure to save urban water resources, but also of great significance to improve the service level of urban water supply and ensure water quality safety.

13. Popularize the leak detection technology of predetermined position and precise fixed point.

Promote the application of pre-positioning leak detection technology and accurate fixed-point leak detection technology, and optimize the leak detection method according to different laying conditions of water supply network. Encourage the use of regional leak detection system technology and intelligent and accurate fixed-point leak detection technology on the basis of establishing GIS and GPS systems for water supply networks.

14. develop and apply the information technology of decision support for leak detection and maintenance of pipe network.

It is encouraged to build a decision support system with the functions of valve closing search, state simulation, accident analysis and decision-making scheduling on the basis of building a GIS system for pipe network, so as to provide decision support for leak detection and maintenance of pipe network.

15. Utilization technology of urban reclaimed water (reclaimed water) Although water has just been used in houses in China, it has been widely used in many water-deficient areas in the world, such as South Africa, the Middle East and California, and the technology is very mature.

16. Establish and improve the technical system of urban reclaimed water utilization.

The recycling of urban sewage should be based on the source and scale of urban sewage, in accordance with the principle of on-site treatment and on-site reuse, adopt corresponding reclaimed water treatment technology reasonably, encourage the study of reclaimed water utilization planning and technical standards, gradually establish a pipe network system of urban reclaimed water utilization coordinated with urban water system and a reclaimed water utilization system combining factory effluent, single building water and residential area water centralized treatment, and formulate and improve sewage recycling standards.

17. Promote the application of reclaimed water utilization technology in urban residential quarters.

When building residential areas in cities and reaching a certain building scale, population or water consumption, we should actively adopt the technology of reclaimed water utilization in residential areas, and use reclaimed water for toilet flushing, cleaning, car washing, greening, environmental and ecological water use, etc.

The price of treated reclaimed water (Beijing area) is about 1.5 yuan /m3. The water consumption for greening in residential areas is relatively large. Due to the low water price, the property management fees charged by property management companies to residents will also be reduced.
