摘　　要：某污水厂采用SBR工艺处理城市生活污水,SBR工艺难以稳定地实现生物脱氮除磷的问题,其系统硝化作用和反硝化作用对进水碳源的利用顺序导致出水TN和TP不能达到GB18918—2002的一级A排放标准。采用分段进水的方法以提高脱氮除磷的效果,研究不同进水流量分配比(λ)对脱氮除磷的影响。结果表明,当进水流量比λ为5∶3时出水TN的效果最好,且各项指标都能达到排放标准。SBR process is adopted in A WWTP to treat city sewage,but it is hard for SBR to stably realize the denitrification and dephosphorization and also the effluent TN and TP could not achieve class A discharge standard GB18918- 2002 because of the order what nitrification and denitrification utilize the carbon source in the influent water. The step- feed mothed can improve the effect of denitrification and dephosphorization. The effects of the different distribution ratio of the influent water（ marked as λ） on denitrification and dephosphorization are researched. The experimental result shows that the effect of the effluent TN is the best and other indicators could also achieve discharge standard when λ is 5∶ 3.
