摘　　要：通过Fenton高级氧化方法对宜昌市黄家湾垃圾处理厂的垃圾渗滤液进行了氧化降解处理,考察了Fe2+、H2O2的用量和pH等因素对垃圾渗滤液COD去除率的影响,研究了引入可见光的情况下加入C2O4-2与Fe2+的比对降解效果的影响,在pH=3.0,H2O2的量为2.0×10-2mol/L,Fe2+的量为2.3×10-3mol/L的条件下,可使垃圾渗透液的COD去除率达70.0%,在加入一定量的草酸根离子(C2O4-2/Fe2+为0.67)的可见光协助下和引入紫外光都能够极大地提高Fenton试剂对垃圾渗滤液的氧化降解的效果,并比较了在不同条件及光源下Photo-Fenton对此垃圾渗滤液的氧化降解.Test was made on the use of fenton process for treatment of landfill leachate of Huangjiawan Refuse Dump of Yichang City. The effects of concentration of H2O2 and catalyst, initial pH on COD removal were investigated. The results indicate that the COD removal could achieve 70.0% under pH=3.0, H2O2 = 2.0 × 10^-2 mol/L and Fe^2＋ =2.3 × 10^-3 mol/L. The system of addition of ultraviolet light and including C2O4^-2 and Fe^2＋ under visible irradiation were also investigated. It is shown both the addition of ultraviolet light and addition of C2O4^-2 （C2O4^-2/Fe^2＋ = 0.67） under visible irradiation all advanced the degradation efficiency. And the effects under different conditions and light on COD removal were studied.
