摘　　要：用SBR工艺处理造纸废水,研究了反应时间、进水CODCr质量浓度、进水pH值及曝气量对处理效果的影响,获得了SBR的最佳工艺参数为:进水、反应、沉淀、排水及待机时间分别为25 min、8 h、2 h、5 min、1 h,采用充氧泵曝气,曝气量7.5 L/h,进水质量浓度为2600 mg/L(以CODCr计),进水pH值为7.0.在此工况下CODCr去除率达70%以上.SBR was used to treat paper mill wastewater.The objective was to evaluate the impact of reaction time,different influent CODCr concentration,pH and aeration rate.The optimal conditions were found to be as follows： feeding time 25 min,reaction time 8 h,settling time 2 h,decanting time 5 min and idle time 1 h,respectively.Aeration rate,influent CODCr concentration and influent pH were found to be 7.5 L/h,2 600 mg/L,7.0,respectively.Under optimal operational conditions,CODCr removal efficiency can achieve above 70%.
