摘　　要：利用一套电絮凝气浮装置,通过室内模拟试验,研究电絮凝气浮法对城市生活垃圾渗滤液中有机物、氨氮、SS等的去除效果。通过正交实验,得到电絮凝气浮法处理渗滤液的最优方案为水流上升速度10 L/h,进水COD浓度6000 mg/L,电流大小7.5A。本实验为电絮凝技术的实际应用提供理论依据和技术支持。Using an electrocoagulation-flotation bioreactor, orthogonal simulative tests were conducted in laboratory to research its operation conditions for removing organic matters, NH3-N and SS in landfill leachate. The result showed the optimum parameters consisting of up flow water speed as 10 L/h, influent of COD concentration as 6000 mg/L and electric current intensity as 7. 5A. The study provides supports to the practical application of electrocoagulation-flotation theoretically and technically.
