摘　　要：电氧化-电絮凝(EO-EC)是两种电化学技术的耦合。本研究构建了以钌铱钛和铁电极一体化的EO-EC的耦合工艺处理含铊工业废水,并通过响应面优化法确定了电氧化-电絮凝(EO-EC)耦合处理含铊废水的最佳操作条件及各因素间的交互作用。研究表明初始pH、电流密度、曝气速率、EO时间占比分别为7.5、5.1 mA/cm^(2)、1.0 L/min、22.7%时,可以得到小试水平下EO-EC处理含Tl实际废水的最优条件,可以实现实际废水中铊的痕量去除。Electrooxidation-electrocoagulation(EO-EC)is a coupling of two electrochemical technologies.The study constructed a coupling process of EO-EC with integrated RuO2-IrO2/Ti electrode and Fe0 electrode to treat industrial wastewater containing thallium.The response surface optimization method was used to determine the best operating conditions for the EO-EC coupling treatment of Tl-containing wastewater and the interaction between various factors.The study showed when the initial pH,current density,aeration rate,and EO time ratio are 7.5,5.1 mA/cm^(2),1.0 L/min,and 22.7%,respectively,the optimal conditions for the EO-EC treatment of actual wastewater containing Tl at the pilot scale can be obtained,achieving trace removal of thallium in actual wastewater.
