摘　　要：采用电絮凝耦合电催化工艺对高浓度表面活性剂废水进行预处理,并探究了阳极材料、电压、电极板数量和电解质类型及浓度等因素对电絮凝耦合电催化工艺性能的影响。结果表明,在电解质为5000 mg/L Na_(2)SO_(4)、铝电极作阳极、电压为4 V、4组电极板最佳条件下电絮凝4 h后,再以BDD电极作阳极、电流密度控制为10 m A/cm^(2)电催化4 h,LAS质量浓度由初始10000 mg/L降至1350 mg/L,LAS降解率为86.24%,整体能耗为14.93 k W·h/kg LAS。A process coupled electrocoagulation with electrocatalysis is used to degrade high-concentration surfactant-containing wastewater.The influences of anode material,voltage,number of electrode plates,and the type and concentration of electrolyte on the process performance are investigated.The results show that LAS concentration decreases from 10000 mg·L^(-1)to 1350 mg·L^(-1),the degradation rate of LAS reaches 86.24%and the overall energy consumption is 14.93 k W·h per kg of LAS when the wastewater has been firstly electro-coagulated for 4 hours under the optimal conditions that 5000 mg·L^(-1)Na_(2)SO_(4)is used as electrolyte,aluminum electrode as anode,the voltage is 4 V and 4 groups of electrode plates are employed,and then it has been electrolyzed with BDD electrode as anode under a current density of 10 m A·cm^(-2).
