摘要:

采用Fenton工艺对较长填埋龄垃圾渗滤液进行处理。试验结果表明,Fenton工艺对经过吹脱后的填埋场渗滤液处理的最佳条件为pH=4、n(H2O2)∶n(Fe2+)=10以及Fe2+投加量为0.08 mol/L。同时,在整个试验过程中发现,氧化与絮凝去除有机物作用的相对大小比值a平均为4.6。

关键词: Fenton工艺, 渗滤液, 氧化, 絮凝

Abstract:

Fenton process has been used for treating landfill leachate which was landfilled for a relatively long time.The results show that the best conditions for treating the landfill leachate are as follows:pH=4,n(Hsub>2O2)∶n(Fe2+)=10 and dosage of Fe2+ is 0.08 mol/L. And the relatively average ratio a of the organisms removed by oxidation and coagulationis 4.6.

Key words: Fenton process, leachate, oxidation, coagulation
