摘要
采用A／O—MBR反应器处理住宅小区生活污水，并实现中水回用。工程应用表明，当进水pH7．2～7．5、COD228～341mg／L、BOD112～189mg／L、SS104—173mg／L和氨氮17．5-24．4mg／L时，系统的COD、BOD、SS和氨氮的平均去除率可分别达到91．2％、96．1％、95．8％和78．7％，出水水质满足撇市污水再生利用景观环境用水水质》（GB／T18921—2002）标准要求，出水可用作绿化、洗车及景观用水，社会、环境和经济效益均较显著。
The Engineering of Domestic Wastewater Treatment and Water Reuse by A/O-MBR Bioreactor The domestic wastewater has been treated by A/O-MBR Bioreactor and reused. When the A/O-MBR Bioreactor influent pH is 7.2-7.5, COD is 228 -341 mg/L, BOD is 112-189 mg/L, SS is 104-173mg/L and NH3-N is 17.5-24.4 mg/L, the COD, BOD, SS and NH3-N removal rate reaches 91.2%, 96.1%, 95.8% and 78.7%. The quality of the effluent was better than the requirements of State Water Quality Standard for Urban Scenic Environment Using （GB/T 18921--2002）. And the effluent can be used for landscape, greenbelt and car-washing etc. The project is considered cost effective and benefit to society and environment.
