摘　　要：试验采用前置厌氧池的DAT-IAT工艺方法,以城市污水为处理对象研究工艺的生物降解过程及除磷效果。试验结果表明:该工艺处理城市污水能获得很好的处理效果且工艺稳定性高。IAT池曝气4hCODCr平均去除率可达到97.6%;氨氮的去除率因受进水氨氮负荷影响使得变化范围较大,从53.3%到98.7%,平均去除率在90%以上;厌氧池的设置使总磷的去除效果尤为突出,平均去除率在90.0%以上。By means of setting up an anaerobic tank in front of DAT-IAT, biological degradation performance and phosphorus removal efficiencies are studied with municipal sewage. It is shown that the process can attain better treatment performance and better stability. The average removal efficiency of COD can reach 98.7% after 4-hour aeration of IAT tank. The ammonia removal efficiency varies with great range from 53.3% to 98.7% as the result of inlet ammonia loading variations and the average removal efficiency is 9...
