Through the systematic analysis of water resources, water supply, wastewater discharge and reclaimed water utilization in Yanqing District of Beijing, the problems of reclaimed water utilization in Yanqing District are pointed out. With the aim of safety, ecology and high efficiency, the water supply of reclaimed water in Yanqing in 2020 Based on the analysis of the demand and demand, we found that all the surplus reclaimed water should be replenished to meet the demand of reclaimed water in different industries such as industry, afforestation, agriculture and municipal miscellaneous use, so that the supply and demand balance will be reached. At the same time, Reclaimed water facilities, and strict management of reclaimed water quality and water quality, puts forward countermeasures and measures to improve the utilization efficiency of reclaimed water and can save a large amount of surface water and groundwater through rational use of reclaimed water, thus promoting the development of circular economy and building a resource-saving society; Yes, the Olympic Winter Games held to create a beautiful water environment provides water protection.
