随着化肥、洗涤剂和农药的普遍使用，废水中氮、磷的含量有了显著增加。氮磷的排放对环境造成了严重的污染，其中最为突出的是水体富营养化。因此,现代污水处理不仅需要从污水中去除COD、SS，还要脱氮除磷。由上海市政院1983年设计，1987年投产的龙华污水处理厂，是当时上海最大的污水厂，服务人口为12.4万人，设计规模为每日10.5万立方米，采用A/O法和曝气生物滤池法双路脱氮除磷。近年来，发现生物滤池出水的氮、磷的不稳定，时常达不到出水标准。通过对这一问题的深入研究，寻求出了一个较好的改进方法，使出水水质稳定在国家《城镇污水处理厂污染物排放标准》（GB18918-2002）中二级排放标准。

With the commonly using of fertilizers, detergents,the content of nitrogen, phosphorus in wastewater has increased significantly. Discharge of Nitrogen and phosphorus caused serious pollution to entironment, the most prominent is the eutrophication. Therefore, a modern sewage treatment requires not only removing COD, SS from the effluent， but also nitrogen and phosphorus. Longhua sewage treatment plant, which was designed by the Shanghai Municipal Academy in 1983 and put into production in 1987，was the largest sewage plant of Shanghai. It can serve a population of 124,000，and daily design size is 105,000 cubic meters.The plant use A/O and BAF Dual technique to remove Nitrogen and phosphorus. In recent years, the Nitrogen and phosphorus of BAF's effluent has been found not stable, which often was less than the effluent standards. Through the in-depth study to this issue，a better way to improve was found out. It can make the water quality of effluentresorted stabilizing in the
