摘　　要：为解决长期困扰企业的水资源紧缺和水质差的问题,设计建设了多源废水处理与再生回用工程。该工程以钢铁废水、生活污水、工业废水、雨水等非常规水源为处理对象,处理出水分质回用于厂区生产工艺用水和循环冷却水系统补充水,使企业年节水量达1 095万t,年COD、BOD、NH3-N以及TP等污染物减排量分别达1 300 t、170 t、500 t及16 t。Project of multi-source wastewater treatment and reuse was designed and built in order to solve the problems of water resource shortage and poor water quality,which has disturbed the interprise for a long time.Non-conventional water resources,such as iron and steel wastewater,domestic sewage,industrial wastewater and rain were treated in this project.The effluent was reused in production processes or recirculating cooling water system supplement,which saved water for 10.95 megatons per year and reduced discharge of COD、BOD、NH3-N and TP for 1 300 tons,170 tons,500 tons and 16 tons.
