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 m3/d and more than 50m3/d(including),and the improved A2/O+MBR process is adopted;the scale of the sewage treatment station is less than 50 m3/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.
