摘  要:
采用Fenton试剂氧化法处理晚期垃圾渗滤液,对初始pH、H2O2/Fe2+比、H2O2投加量及反应时间等影响化学需氧量(COD)去除率的各因素进行了研究。得出Fenton试剂氧化法处理晚期垃圾渗滤液的最佳条件为:初始pH为4,H2O2/Fe2+比为5:1,H2O2投加量为0.05mol·L-1,反应时间为2.5h。此时COD去除率可达73.1%。

摘  要:
The factors that affected the removal of chemical oxygen demand(CODcr) from old landfill leachate treated by Fenton reagent, such as sample's initial pH value, H2O2/Fe2+ dosing ratio, H2O2 dosage and reaction time were investigated in this paper. The results showed that the optimal condition as following, initial pH value of landfill leachate was 4, H2O2/Fe2+ dosing ratio was 5:1, H2O2 dosage was 0.05 mol·L-1 and reaction time was 2.5 h. As a result, the removal rate of CODcr from Old landfill leachate was 73.1% under this condition.
