The landfill leachate after biochemical treatment using the"A/O-MBR"process was selected as the research subject,and three-dimensional electrode electrocatalytic oxidation technology was employed for further treatment.Experimental investigations were conducted to examine the impacts of reaction time,current density,aeration rate,and initial pH on the advanced treatment.The results demonstrated that optimal process parameters for advanced treatment of landfill leachate were achieved as follows:a reaction time of 60 minutes,a current density of 15 mA/cm2,an aeration rate of 500 mL/min,and an initial pH value of 5.0.Continuous experiment was carried out under these optimized conditions,and the results show that with an average influent COD concentration at 935 mg/L,the effluent water exhibited an average COD concentration at 201 mg/L.The system operated stably with an average COD removal efficiency reaching up to 78.50％.
