微电解-Fenton氧化预处理垃圾渗滤液的应用研究

An Application Research on Landfill Leachate Pretreatment by Micro-electrolysis-Fenton Process

采用微电解-Fenton氧化组合应用的方式预处理垃圾渗滤液,研究了其可行性及不同工艺条件对COD去除率的影响。结果表明:最佳微电解进水pH值控制在2.5,反应时间为40min,出水中H2O2的投加量为8mL/L,反应时间为60min,在此条件下,最高去除率可达到77.4%。

The combined application of micro-electrolysis-Fenton process was usd to pretreatment landfill leachate, to study the feasibility of it and the effect of different process conditions on COD removal efficiency The results showed that the optimal micro-electrolytic influent pH should be controled at 2.5 and the re-action time was 40 minutes,a dosage of H2O2 in water was 8ml/L,and the reaction time was 60 minutes in this condition,the maximum removal rate can be achieved 77.4%.
