摘　　要：污水处理生化系统采用A/O法,由于来水中氨氮含量过高,导致生化系统进水氨氮达到300 mg·L^(-1)以上,高氨氮对生化系统造成冲击。主要对影响生化系统正常运行的因素展开分析,探讨有利于生化系统正常运行的工况,同时对整个生化系统工艺方面存在的问题进行了改进和优化,最终实现高氨氮污水高效去除。A/O method was adopted in the biochemical system of sewage treatment. Due to the high ammonia nitrogen content of sewage in the incoming water, the ammonia nitrogen in the influent of the biochemical system was more than 300 mg·L^(-1), and the high ammonia nitrogen impacted the biochemical system. In this paper, the factors affecting the normal operation of the biochemical system were mainly analyzed, and the working conditions being conducive to the normal operation of the biochemical system were discussed. At the same time, the problems existing in the process of the whole biochemical system were improved and optimized, and the high efficiency removal of high ammonia nitrogen waste water was finally achieved.
