The combination of pretreatment, biochemical method and membrane treatment is the mainstream process of domestic landfill leachate treatment. Although it can quickly and stably reduce various pollutants in the leachate, the produced leachate membrane concentrate contains high concentrations of refractory organics, salts and other inorganics. The removal of refractory organic matter is a problem for the treatment of leachate concentrate.The landfill leachate membrane concentrate from a landfill sitein Shenzhen was treated bythree-dimensional electrochemical oxidation,UV-Fenton and electrochemical oxidation-UV/Fenton-electrocatalytic oxidation combination process. The removal efficiency of COD, ammonia nitrogen, and total nitrogen were 97.6%, 98.8%, and 93.5% followingelectrochemical oxidation for 2 h, UV/Fenton treatment for 1.5 h, and electrocatalytic oxidation for 2 h, respectively. The effluent met the direct discharge requirements of the pollution control standard of the domestic landfill (GB16889-2008). The operational cost of landfill leachate membrane concentrate by such process treatment is 93.2RMB/m³.
