摘　　要：村镇污水处理工艺选取受项目实施地域、规模、水环境等诸多因素影响,应根据具体情况加以选取。文章以天津市静海区村镇污水治理项目为例,分析了镇村污水处理工艺方案选择,即污水处理站规模小于500 m^(3)/d且大于50 m^(3)/d(含),采用“改进型A^(2)/O+MBR”工艺;污水处理站规模小于50 m^(3)/d,采用“水解酸化+生物接触氧化+沉淀+过滤”工艺。项目实施后,出水数据达到标准,项目的实施可为类似地区村镇污水治理提供参考。The selection of rural sewage treatment process is affected by many factors,such as project implementation area,scale,water environment and so on,which should be selected according to the specific situation.Taking the rural sewage treatment project in Jinghai District of Tianjin as an example,it analyzes the selection of the town and village sewage treatment process,that is,the scale of the sewage treatment station is less than 500 m^(3)/d and more than 50m^(3)/d(including),and the improved A^(2)/O+MBR process is adopted;the scale of the sewage treatment station is less than 50 m^(3)/d,and the process of hydrolysis acidification+biological contact oxidation+sedimentation+filtrationis adopted.After the implementation of the project,the effluent data reached the standard,and the implementation of the project can provide reference for the sewage treatment of villages and towns in similar areas.
