摘　　要：研究了前置缺氧A2/O工艺在不同进水配比条件下脱氮除磷的效果.结果表明,系统在前置缺氧池进水:厌氧池进水分别为3:7,5:5和7:3进水配比的条件下,均可以保持较稳定的TP去除效果,TP去除率达90%以上,出水TP低于1.0 mg/L;当进水配比为3:7和5:5条件下,TN去除率可达74%以上,当进水配比为7:3时,TN去除率略有下降,约为71%左右.The test studies nitrogen and phosphorus removal of the pre-anoxia A^2/O process in different influent distribution.The research shows that the system has good result in disposal of TP in 3∶7,5∶5 and 7∶3 ratio of influent distribution,the phosphorus removal can reach 90 %,TP of the effluent is mostly blow 1 mg/L;The nitrogen removal can reach 74 % on the condition of 3∶7 and 5∶5 influent distribution,the nitrogen removal is acout 71 % on the condition of 7∶3 influent distribution.
