摘　　要：以活性污泥法为工艺的城市污水处理厂,针对其在运行中出现的氨氮处理率波动性变化的问题,根据实测数据,找出了氨氮的去除效果与污泥负荷、溶解氧、温度等因素的关系。研究发现,对于活性污泥曝气系统,在去除氨氮必需的辅助条件(低污泥负荷、长泥龄、生物相稳定)具备的情况下,供氧量的提高对于氨氮的去除影响起到关键作用,运行结果表明溶解氧增加后氨氮去除率明显提高。According to the operation dates of the activated sludge process WWTP, the removal rate of NH3-N is related with sludge load, DO and temperature, etc. Research found that in a activated sludge process, DO acts a important role in increasing the NH3-N removal rate when the essential conditions such as low sludge load, long sludge age and stable biofaeies. Operation result showed that increasing DO can significant increased the NH3-N removal rate.
