摘　　要：采用Fenton试剂处理反渗透浓缩渗滤液(简称浓缩液),并探讨了双泥SBR工艺对Fenton处理后浓缩液与人工配水混合处理的可行性。结果表明,Fenton氧化对COD、TN和NH3-N的平均去除率分别为43.5%、22.5%和19.5%。对溶解性有机物(DOMs)的去除率为52.5%,其中胡敏酸(HA)、富里酸(FA)和亲水性有机物(HyI)的去除率分别为57.9%5、9.4%和21.1%。双泥SBR系统对Fenton处理后浓缩液与生活污水的混合液处理效果较好,对COD、NH3-N、TN和腐殖酸的平均去除率分别为85%7,5%7,0%和70%。Fenton氧化和SBR联用,能有效处理难生物降解的浓缩液。The treatment of concentrated leachate rejected from reverse osmosis（RO） with Fenton reagent was investigated,and the feasibility of treating mixture of landfill leachate and synthetic wastewater was studied using two-sludge SBR systems.The results showed that the average removal efficiencies for COD,TN and NH3-N were 43.5%,22.5% and 19.5%,respectively. The removal rates for dissolved organic materials（DOMs）,humic acid（HA）,fulvic acid（FA） and hydrophilic fraction were 52.5%,57.9%,59.4% and 21.1%,respectively.The two-sludge SBR system had a favorable treatment efficiency of mixture of liquids,and the average removal efficiencies for COD,NH3-N,TN and humic substances were 85%,75%,70% and 70%,respectively.The combined advanced treatment of Fenton oxidation process followed two-sludge SBR could effectively treat bio-refractory contaminants in concentrated leachate.
