The　lab-scale　treatment　of　biologically　pretreated　landfill　leachate　by　electro-Fenton　(E-Fenton)　was　carried　out　in　a　continuous　flow　reactor　using　Ti/RuO2-IrO2　mesh　anodes　and　cathodes.　The　effects　of　important　parameters　including　voltage,　hydraulic　retention　time,　H2O2/Fe2+　molar　ratio,　and　H2O2/COD0　molar　ratio　on　COD　removal　were　investigated,　and　the　optimum　conditions　for　this　advanced　oxidation　process　were　found.　There　was　an　optimal　H2O2/Fe2+　and　H2O2/COD0　molar　ratio　so　that　the　highest　COD　removal　rate　was　achieved.　The　Dissolved　Organic　Matters　(DOM)　in　the　leachate　were　analyzed　using　ultraviolet　spectrum　and　Excitation　Emission　Matrix　(EEM)　spectrofluorimetry.　About　84.58%　COD　was　removed　and　colority　was　completely　removed　after　the　E-Fenton　process.　The　results　indicate　that　the　E-Fenton　process　is　an　effective　technology　for　the　treatment　of　biologically　pretreated　landfill　leachate.
