摘　　要：采用电絮凝-膜过滤技术处理含镉废水。考察了进水pH值、电流密度和废水的流量对镉的去除率的影响。结果表明:该技术的最佳进水pH值为8,电流密度为20A/m2,废水的流量为2L/min。在此条件下,对不同质量浓度的含镉废水进行处理,镉的去除率均在96%以上,最高可达99.55%。An electrocoagulation-membrane filtration process was used to treat cadmium containing wastewater.The effects of inflow pH,current density and wastewater flow on the removal rate of cadmium were investigated.The results show that the optimal technological parameters of this process are as follow：pH value of inflow 8,current density 20A/m2,and flow of wastewater 2L/min.Under these conditions,in treatment of wastewater containing different mass concentrations of cadmium,the cadmium removal rate is above 96%,the highest can reach 99.55%.
