【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0.5 m3/h,曝气5 h,停曝搅拌75 min,沉淀75 min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353.8、33.70、0.714 mg/L时,出水CODCr、NH3-N、TP的平均质量浓度分别达到30.26、9.322、0.458 mg/L。均能达到生活杂用水标准。更多还原

【Abstract】 As SBR process has characteristic of flexible operation modes,it can be used to remove different kinds of pollutants.Based on this characteristic,the removal rates of CODCr,NH3-N,TP under different operation conditions were investigated through changing operation modes of SBR process,meanwhile,the optimal operation parameters were determined.When the average mass concentration of CODCr,NH3-N,TP in influent water were 353.8,33.70,0.714 mg/L respectively,under the optimal operation parameters that the inlet agitation time was 45 min,the input air quantity was 0.5 m3/h,the areation time was 5 h,the agitation time after areation was 75 min,the sedimentation time was 75 min,after 8 cycles of stable operation,the average mass concentration of CODCr,NH3-N,TP in effluent water reached 30.26,9.322,0.458 mg/L respectively,which met the standard for urban miscellaneous water consumption.更多还原
