摘要
采用芬顿+活性炭联合工艺对晚期垃圾渗沥液进行处理,考察反应pH、H2O2投加量、FeSO4·7H2O投加量、反应时间、活性炭投加量对垃圾渗沥液COD去除的影响。结果表明芬顿法的最佳条件为:初始pH为4,[H2O2]为1.70 g/L,[Fe2+]为1.21 g/L,反应时间为1.0 h,此时COD最大去除率为71.3%。活性炭法最佳条件为:初始pH为4,活性炭投加量为4 g/L,反应时间1.5 h,此时COD最大去除率为55.2%。芬顿+活性炭联合工艺对晚期垃圾渗沥液COD去除总效率为85.1%。
The combination process of Fenton oxidation and activated carbon adsorption was used to treat late leachate,and the effects of reaction pH,H2O2 dosage,FeSO4·7H2O dosage,reaction time and activated carbon dosage on COD removal of leachate were investigated.The results showed that the optimum conditions of Fenton oxidation were as follows:initial pH was 4,[H2O2]was 1.70 g/L,[Fe2+]was 1.21 g/L and reaction time was 1.0 h.The maximum removal rate of COD was 71.3%.The optimum conditions of activated carbon adsorption were as follows:initial pH was 4,the dosage of activated carbon was 4 g/L,and the reaction time was 1.5 h.The maximum removal rate of COD was 55.2%.The total removal efficiency of COD from late leachate by combination process of Fenton oxidation and activated carbon adsorption was 85.1%.
