摘　　要：通过分析脱氮机理,提出了A/O工艺的改良A/O/N工艺方案.结合城郊生活污水处理进行了A/O/N工艺影响因子的正交试验,提出了A/O/N工艺处理城郊生活污水的最佳工艺条件,并分析了各工艺条件对氨氮去除效果的影响.Through analyzing the nitrogen removal mechanism of the traditional A(Anoxic)/O(Oxic),a process A(Anoxic)/O(Oxic)/N(Nitrification) brought was put forward as its modificated process.By an orthogonal test about the influential factors of A/O/N with the sewage in outskirts,the best operation conditions for the domestic wastewater treatment in outskirts are put forward and the influences of the conditions for the effect of ammonia-nitrogen removal are analyzed.
