摘　　要：采用自行开发的新型PbO2/Ti电极作阳极,对高浓度垃圾渗滤液进行电化学氧化法处理,研究了极板间距、电流密度、温度和电解时间对COD和NH3-N去除率的影响,考察了处理后出水的可生化性。研究结果表明:极板间距合适时,COD和NH3-N的处理效果较好;随着电流密度的增加、温度的升高和电解时间的延长,COD和NH3-N去除率均提高;处理后出水可生化性良好。The landfill leachate was treated by the electrochemical oxidation technology using the novel and self-prepared PbO2/Ti anode.The effects of electrode distance,current density,temperature and electroanalysis time on the COD and NH3-N removal efficiencies were studied.At the same time,the biodegradability of treated waste was also studied.The results indicated that the COD and NH3-N removal efficiencies are high when the electrode distance is appropriate;with the increase of current density,temperature and electroanalysis time,the COD and NH3-N removal efficiencies are increased.Consequently,the biodegradability of treated waste is excellent.
