Fenton氧化法深度处理垃圾渗滤液的试验研究

采用Fenton氧化法对经生化处理后的垃圾渗滤液进行深度处理。结果表明,Fenton反应最佳工艺条件:初始pH值为3,H2O2加入量为3.0mL/L,FeSO4.7H2O加入量为3.5g/L,反应时间120min。生化处理后的垃圾渗滤液经Fenton氧化法深度处理后,CODCr由处理前的300mg/L,降至处理后的93mg/L,去除率达69.0%,出水水质达到新修订的《生活垃圾填埋场污染控制标准》(GB16889-2008)排放标准。

Experimental Study on the Advanced Treatment for Landfill Leachate by Fenton Oxidation Process

Fenton oxidation process was used in the advanced treatment for landfill leachate which was treated by biological process.The optimum conditions of Fenton reaction were that initial pH was 3.5,the dosage of H2O2 was 3.0mL/L,the dosage of FeSO4·7H2O was 3.5g/L,and the whole reaction time was 120 min. Under this condition,CODCr was reduced from 300 mg/L to 93 mg/L,which was less than the revised national emission standard（GB16889-2008）,and removal rate was 69.0%.
