摘　　要：采用Fenton氧化法处理长沙市黑糜峰垃圾填埋场垃圾渗滤液原液,考察了影响COD去除率的各种因素,包括初始pH值、FeSO4.7H2O投加量、双氧水投加量、反应时间及投加方式等,试验结果表明:在初始pH值为3、FeSO4.7H2O投加量为0.5%、双氧水投加量为18 mL/L、反应时间为100 min、投加方式为3次投加的条件下,可使垃圾渗滤液原液的COD去除率达40%左右,并提高了生化比,为后续生物处理改善了条件。Landfill leachate was treated by Fenton Oxidation Process. The effect of initial pH on wastewater, the dosages of H2O2 and FeSO4 · H20, the reaction time and the adding mode were investigated. The optimal condition was obtained as follows： pH = 3,c （H2O2）= 18 mL · L^-1 ,c （FeSO4 · H2O） = 0.5%,t = 100 minutes, and adding mode = 3 times of adding. When these conditions are met, the COD removal efficiency can reach about 40% and therefore improves the condition for the later biologytreatment.
