摘　　要：对北京 2 2个运行中的中水设施进行了调研。中水水源主要为淋浴和盥洗排水 ;回用以厕所冲洗、水景、绿化、洗车为使用次序 ;目前运行效果较好的工艺为生化 物化工艺。通过分析发现普遍存在设施能力不能充分利用、运行成本过高的现象。提出应准确确定中水设施规模 ,调节构筑物的容积 ,并应充分发挥经济杠杆的作用制定合理的水价体系 ,培育完善的中水回用市场。Wastewater reuse units in Beijing were investigated. Most of them are bathing and washing discharges and reused for lavatory flushing, water scenery, garden greening and car washing. Now the combined biological and physico-chemical process seems the best. However a lot of facilities are not fully used and expensive. So the size of each unit and the capacity of structures must be determined properly, the water price should be regulated according to the so-called market rule to active the economical measure. Also reasonable water price must be issued to create a perfect market for wastewater reuse.
