介绍了我国住宅小区灰水回用现状及灰水处理工艺，分析了各种处理工艺的优缺点，并收集住宅灰水，检测COD、N H3-N、T N、T P和浊度5项水质指标，搭建超滤膜和人工湿地装置，对灰水进行了处理。结果表明：住宅灰水COD、N H3-N、T N、T P指标值较低，属于优质回用水水源；超滤装置对灰水浊度有较高的去除效果，平均出水浊度2．0NTU ，去除率97．1％，并能够去除灰水中部分COD、TN、TP；潜流式人工湿地能够有效去除灰水污染物质，其中COD平均去除率可达88．6％。经过技术比较，两种工艺处理住宅灰水是可行的。

This article introduces the current situation of residential grey water treatment and reuse in China ,and also discusses the advantages and disadvantages of grey water treatment .And then it determines COD ,NH3 -N ,TN , TP and turbidity by collecting the college dormitory district and constructs the artificial wetland and ultrafiltration to treat the grey water .The results show that the concentrations of COD ,NH3 -N ,TN ,TP and turbidity are low , belong to high quality reuse water source ;the ultrafiltration appliance has a high removal efficiency of turbidity with 2 .0 NTU of the average turbidity of treated water and 97 .1% of the removal efficiency ,and can partly remove COD , TN ,TP;the constructed wetland can effectively remove the pollutants in the grey water ,and the average removal efficiency of COD is 88 .6% .Therefore ,it is feasible to use these two processes to treat residential grey water after technical comparison .
