摘要：

After　the　UASB　treatment　in　the　trial　experiment,　the　landfill　leachate　in　Liulitun　Landfill　Yard,　with　COD　and　ammonia-nitrogen　concentration　being　2350-2600　mg/L　and　about　1300　mg/L　respectively,　was　inefficient　in　being　biochemicalized　and　low　in　C/N,　which　required　physico-chemical　treatment　before　advanced　biochemical　treatment.　This　experiment　introduced　Fenton　reagent　oxidation　first　and　then　chemical　coagulation,　so　as　to　compare　removal　effects　under　different　dosages.　Results　showed　that　the　combination　of　oxidation　of　Fenton　reagent　and　chemical　deposition　was　effective　in　the　removal　of　turbidity,　COD　and　ammonia-nitrogen　in　landfill　leachate.　Under　the　condition　of　cFe2+　=　0.03　mol/L,　cH2O2　=　0.09　mol/L,　ρPAC　=　800　mg/L,　ρKP1207B　=　10　mg/L,　this　method　was　particularly　effective,　with　the　removal　rates　being　62%,　54%　and　35%　respectively.
