摘　　要：从沿江地区村镇污水的特点及居民的生活习惯出发,采用原位生态修复技术,设计出一种生态混凝土墙,利用现场地形条件将湖塘改造成生活污水处理点,采用生态调节沟/生态混凝土墙/原位增氧/生物强化/人工浮岛组合工艺处理安徽马鞍山某村镇360 m3/d污水,实现污水的生物处理和水环境原位生态修复。工程运行表明,出水COD、NH3-N、TP等污染物指标达到《城镇污水处理厂污染物排放标准》(GB 18918—2002)的一级B标准,湖塘内水质维持在《地表水环境质量标准》(GB 3838—2002)Ⅲ类水质,水体透明度达100 cm。对于南方地区村镇污水处理,具有一定的工程示范作用和推广应用价值。From the consideration of rural sewage characteristics and resident living habits along rivers, a kind of ecological concrete wall was designed using in-situ bioremediation technology, and ponds were reconstructed into treatment places of domestic sewage by means of site terrain condition. The com- bined process of ecological equalization channel, ecological concrete wall, in-situ oxygenation, bioaug- mentation and constructed floating island was used to treat 360 m^3/d sewage from a village in Ma＇ ans- han, Anhui Province, thus achieving biological treatment of sewage and in-situ bioremediation of water environment. The project operation showed that the effluent COD, NH3 -N and TP met the first level B criteria specified in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant （ GB 18918 -2002）, and the water quality in the pond met IlI criteria specified in the Environmental Quality Standards for Surface Water （GB 3838 -2002） with a transparency of 100 cm. The demonstration project has a certain application value for rural domestic sewage treatment in southern China.
