摘　　要：介绍了内蒙古市政污水处理厂二级生物处理后的中水的深度处理工艺(机械搅拌澄清池和曝气生物滤池的组合工艺)流程和进出水水质情况,分析了机械搅拌澄清池和曝气生物滤池的工艺特点。经深度处理后,出水COD、氨氮、总磷等水质指标均显著降低,完全符合回用要求,能够满足火电厂生产需要。实践表明,该处理工艺可缓解水资源紧张的现状,有着广泛的应用前景。The advanced treatment process flow （combined mechanical stirring clarification pool＋biological aeratedfilter 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 technological characteristics of the stirring clarification pool and biological aerated filter are analyzed. After the advancedtreatment, 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 powerplants. Practice results show that the treatment process can ease the water resource shortage situation, having wideapplication prospect.
