摘　　要：SBR法以其运行方式灵活的特点可以实现对不同污染物去除的控制。试验基于此特点,通过改变SBR工艺的运行方式,考察不同运行条件下CODCr、NH3-N、TP的去除率,从中确定最佳运行参数。在进水搅拌45min,进气量0.5m3/h,曝气5h,停曝搅拌75min,沉淀75min的最佳运行参数下,稳定运行8个周期,进水CODCr、NH3-N、TP的平均质量浓度分别为353.8mg/L、33.70mg/L、0.714mg/L时,出水CODCr、NH3-N、TP的平均质量浓度分别达到30.26、9.322、0.458mg/L。SBR process can be achieved for different pollutant removal by controlling. Based on this characteristics the feature compared the removal rate of CODCr NH3-N,TP under different operating conditions using a changed mode of SBR operation, then ascertaining the optimum operating parameters. The optimum operating parameters gained is as follow：the mixing time is 45min during the falling in of wastewater, the feed rate is 0.5m3/h, aeration time is 5h,aeration after mixing time is 75 min, sedimentation time is 75 min,and then operated stably for eight cycles,the he average quality concentration of the CODCr NH3-N,t TP in the influent were 353.8mg/L,33.70 mg/L, 0.714 mg/L respectively, and the average concentration of CODCr NH3-N,TP in the effluent were 30.26mg/L, 9.322 mg/L,0.458 mg/L respectively.
