摘　　要：面源污染是城市水环境治理进程中需要长期应对的难题。市政雨水排放口是雨水径流污染排向水体的最后一个环节。常用的雨水排放口净化技术可分为沉淀预处理和生态净化处理两大类,常见的沉淀预处理设施有水力旋流分离器、营养物分离器、沉淀塘、调蓄池等,生态净化处理设施有生态滤池、雨水湿地、生态缓冲带、浮动湿地、MABR等。总结分析了各种净化设施的净化效率、技术特点、应用场景等,进行了工程实践,以期为市政雨水排放口净化处理工艺选择提供帮助,并为今后技术研究提供思路。Non-point source pollution is a long-term problem that needs to be solved during the process of urban water environment governance.Municipal rainwater outfall is the last link of rainwater runoff pollution discharge to water body.The commonly purification technology can be divided into two categories of precipitation pretreatment and ecological purification treatment.The common precipitation pretreatment facilities include hydrocyclone separator,nutrient separating baffle box,sedimentation basin,regulation tank and so on.Ecological purification treatment facilities include ecological filter,rainwater wetland,ecological buffer zone,floating wetland,membrane aeration bioreactor(MABR)and so on.The purification efficiency,technical characteristics and application scenarios of various purification facilities are summarized and engineering practice was carried out,in order to provide help for the selection of purification treatment process of municipal rainwater outfall as well as ideas for technical research in future.
