Analysis And Design On Water Saving Of Residential Quarters

With the development of economy,the shortage of water resources has increasingly become the "weakness" of China’s social and economic development,and the proportion of water consumption in urban residential area is getting higher and higher.To deal with the water saving problems of residential areas will be not only useful to solve the problem of water shortage in China but also to speed up the construction of water-saving society.Therefore,this article analyses the use of water-saving appliances,cold water supply system,hot water supply system and reclaimed water treatment system to save water resources.With introducing some domestic and foreign water-saving measures firstly,it is determined that ceramic valve core faucet,two water tank,constant temperature cold and hot water mixed tap are suitable for popularization in a residential district at present by comparing different water-saving appliances(water-saving faucet,water saving toilet,water saving shower)characteristics.In addition,there are many water supply ways in our country and the energy consumption varies greatly with different water supply modes.It is obtained that variable frequency non negative pressure water supply is reasonable in the high-rise residential water supply by comparing with high water tank water supply,air pressure water supply,variable frequency water supply,add-pressure water supply,variable frequency non negative pressure water supply.At the same time,in the hot water supply system is also analyzed in this article.The main reason of invalid cold water is that hot water supply lines are too long to circulate in time.Therefore,the design should shorten the length of water supply as far as possible,or take the riser cycle and branch circulation to reduce the invalid water.Secondly,from the perspective of the reuse of water resources and combing with the relevant technical requirements of reclaimed water reuse,contacting oxidation method is more suitable for domestic waste water in residential area by comparing different reclaimed water treatment processes.Finally,setting an example of water saving design in Hebei,the paper completed the design and calculation of the water supply system,drainage system,reclaimed water system.The paper also carried on the economic accounting to the reclaimed water treatment system and drew the relevant drawings...
