摘　　要：采用可溶性阳极材料(Fe,A1)通过电絮凝法处理生活废水。实验研究了可溶性阳极材料、电流密度、废水的pH、电导率和电解时间等因素对废水浊度及COD去除率的影响,并确定了最佳工作条件。结果表明:Al电极较Fe电极具有更好的处理效果。电絮凝法对生活废水的浊度和COD去除率分别可迭95％和59％。Electrocoagulation with Aluminum or Iron as soluble anode substances was used to treat domestic waste water. The factors influences on removal efficiencies of turbidity and COD, such as soluble anode substances, current density, pH of wastewater, conductivity and electrolytic time had been investigated. The results showed that Al electrode was preferable to Fe electrode for the treatment effect and the removal efficiencies of turbidity and COD were 95% and 59% respectively for domestic wastewater.
