摘　　要：采用膜化学反应器对造纸废水的二级生化出水进行了实验 ,讨论了废水通过膜化学反应器时 ,温度、pH值、氧化剂AK的剂量、曝气量等主要影响因素对废水CODCr去除率的影响 ,结果表明 ,最佳工艺条件下CODCr、色度的去除率达 87 1%、95 % ,出水CODCr<10 0mg L ,出水完全可以回收利用。A membrane chemical reactor was used to treat the secondary biochemical effluent of paper mill wastewater.The impact of the main factors,such as temperature,pH,dose of the oxidant AK and aeration rate on the removal rate of COD Cr was discussed when wastewater flowed through the membrane chemical reactor.The results showed that the removal rate of COD Cr and colourity were 87.1%, 95%,and COD Cr in treated water was lower than 100 mg/L on the optimum technological condition.The treated water could also be reused.
