摘　　要：河南某合成氨生产企业,其生产废水氨氮浓度高,生化效果差,本研究在预处理和生化阶段分别采用MAP和A/O工艺对其进行处理。工程实践表明,该工艺具有很好的处理效果,且工艺技术可靠、运行稳定、维护管理方便。经该工艺处理后,COD、NH3-N、SS的去除率分别为82.06%、92.94%、72.22%,处理出水达到合成氨工业水污染物排放标准(GB 13458-2001)的一级排放标准。同时,出水回用于生产后可取得显著的经济效益和社会效益。There was a synthetic ammonia production enterprise in Henan province,the production wastewater of which contained high ammonia concentration and poor biological effects.Because of that,in preprocessing and biochemical stage,MAP and A/O process were used.Engineering practice showed that the process had a very good treatment effect,and the technology was reliable,stable operation,easy maintenance and management.After the treatment process,COD,NH3-N,SS removal rates were 82.06%,92.94%,72.22%,repectively,and the treated effluent achieved ＂industrial water pollutant discharge standards ammonia＂（GB 13458-2001） of an emission standard.At the same time,when we used the back water for production,we gained significant economic and social benefits.
