【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。更多还原

【Abstract】 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.更多还原
