摘要
采用"Fenton氧化+双碱软化"法处理垃圾渗滤液膜滤浓缩液,考察了初始pH值、H_2O_2投加量、H_2O_2/Fe^(2+)摩尔比、反应时间和双碱投加量对CODcr和硬度去除率的影响并确定最优处理方案。结果表明:"Fenton氧化+双碱软化"法处理垃圾渗滤液膜滤浓缩液有很好的处理效果,对CODcr的去除率可达81%,硬度去除率可达98.5%。
Landfill leachate membrane filtration concentrate was treated by Fenton oxidation and double alkali softening processes.The initial pH value,H2O2 dosage,H2O2/Fe^2＋ molar ratio,reaction time and double alkali dosage were determined to remove CODcr and hardness.The optimal solution was proposed.The results show that the＂Fenton oxidation＋ double alkali softening＂method has a good treatment effect on the landfill leachate membrane filtration concentrate.The overall removal rate of CODcr could reach 81%and the hardness removal rate could reach98.5%.
