摘　　要： 为了有效控制重金属废水对环境的污染,采用电絮凝-膜过滤技术处理含铜废水,考察了进水pH、电极电流密度和水流量对铜去除率的影响。结果表明:该技术的最佳进水pH值为5.8,电极电流密度为10 A/m2,水流量为2 L/min。在此条件下,对不同浓度的含铜废水进行处理,铜去除率均在95%以上,最高可达99.02%。由此可见,电絮凝-膜过滤技术对含铜废水具有良好的处理效果。 To control the pollution of heavy metal ionic wastewater to the environment effectively,combination technique has been a growing trend in recent years.This paper examines the influences of inflow pH,electrode current density and flow rate on removal rate of copper during the electrocoagulation-membrane filtration processing of copper containing wastewater.The results show that the optimal value of inflow pH is 5.8,the electrode current density is 10 A/m2 and the flow rate is 2 L/min.To process the copper containing wastewater of different concentrations on such conditions,the removal rate of copper is over 95% on average and can be up to 99.02%.This proves the good effect of electrocoagulation-membrane filtration technology to treat wastewater containing copper.
