| 摘 要： | 利用Fenton—混凝沉淀法预处理广西某垃圾焚烧发电厂和垃圾填埋场的垃圾渗滤液,对Fenton试剂以及混凝沉淀进行了单因素分析,分别研究了垃圾渗滤液在不同的nFe2+]/nH2O2]、H2O2投加量、FeSO4投加量、pH值、反应时间、PAC投加量等条件下的处理效果。结果表明:垃圾渗滤液经Fenton—混凝预处理,对COD、色度、SS处理效果好,对NH3—N去除效果不明显;渗滤液的可生化性有所提高,可进行后续生化处理。

| Abstract: | The landfill leachate from a waste incineration power plant and landfill site in Guangxi was pretreated by Fenton-coagulation sedimentation method,the single factor analysis of Fenton reagent and coagulant sedimentation was carried out and the treatment effects of landfill leachate under different conditions of nFe2+]/nH2O2],H2O2,FeSO4,pH value,reaction time and PAC were studied.It was found that the pretreatment of landfill leachate by Fenton had good effect on COD,chroma and SS treatment,but no obvious effect on NH3—N removal.The biodegradability of leachate was improved,and subsequent biochemical treatment could be carried out. |
