摘　　要：根据生物除磷和脱氮的机理,污水的脱氮除磷存在基质竞争和泥龄等方面的矛盾。为了分析和解决这个问题,设计开发了一种新的污水生物处理工艺——SBR-BAF复合工艺,并以模拟城市生活污水为处理对象对该工艺的处理效能进行了考察。试验结果表明,系统对COD(不计BAF加入的外碳源)、TP、NH4+-N和TN的平均去除率分别为96%、98%、93%和84%,出水中COD、TP、NH4+-N和TN的平均浓度分别为20、0.23、3.24和7.68 mg/L,各项水质指标均达到《城镇污水处理厂污染物排放标准》(GB 18918-2002)规定的一级标准中的A标准。Based on the mechanism of biological phosphorus and nitrogen removal, the collision on mainly substrate and sludge retention time is given. In order to solve this problem, a new biological process, SBR-BAF hybrid process used for dealing with wastewater was developed. It was applied for dealing with simulated domestic sewage to verify the efficiency of this process. The experimental results show that, the mean removal efficiency of COD, TP, NH4^＋-N and TN is 96% , 98% , 93% and 84% , respectively. The mean effluent concentration of COD, TP, NH4^＋-N and TN is 20, 0.23, 3.24 and 7.68 mg/L respectively, which means every index can meet the first class （A） of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant.
