| Abstract: | The current status of leachate treatment in garbage landfills and its treatment difficulties were elaborated and summarized. Based on the advantages and disadvantages of various landfill leachate treatment technologies, a multi stage treatment composed of pretreatment, bio treatment and deep treatment was suggested as an ideal treatment. A new way to treat landfill leachate was presented. It combines electrochemical and oxidation ditches with sand filtration. The advantages of the new technique were also analyzed. |
