摘　　要：通过对某市第一城市污水处理厂10万吨/天废水处理工艺调试和运行的介绍分析,指出利用氧化沟为主体的二级生物工艺处理高浓度城市污水时,在氧化沟混合液的污泥浓度(MLSS)达到6~7 g/L,生化系统COD去除率达到95%以上,NH3-N去除率达到80%以上,TP去除率达到90%以上,TN去除率达到70%以上。Through to city first sewage treatment plant 10 million tons/day wastewater treatment process of commissioning and operation analysis. It is pointed out that using oxidation ditch as the main secondary biological process to deal with high concentration of urban sewage, in the mixture of oxidation ditch sludge concentration （MLSS） to 6-7 g/L. Students COD removal rate reached more than 95 %, NH3-N removal rate reached more than 80 %, TP removal rate reached more than 90 %, TN removal rate reached more than 70 %.
