The advanced treatment process flow (combined mechanical stirring clarification pool+biological aerated filter process) of the recycled water after being treated by secondary biological treatment in Inner Mongolia Munici-pal Sewage Treatment Plant and the situation of its influent and effluent water quality are introduced. The technolog-ical characteristics of the stirring clarification pool and biological aerated filter are analyzed. After the advanced treatment,the water quality indexes,such as the effluent COD,ammonia nitrogen,total phosphorus,etc.,are all de-creased obviously,meeting completely the reuse requirements and satisfying the production needs of thermal power plants. Practice results show that the treatment process can ease the water resource shortage situation ,having wide application prospect.
