摘　　要：垃圾渗滤液是一种较难处理的废水,本文通过混凝一吸附法的预处理实验研究,结果表明:当硫酸铝投量在500mg/L、活性炭投量在30g/L时,可将渗滤液中COD的浓度从1856mg/L降为640mg/L,COD去除率达到66%;渗滤液颜色由原来的深褐色变成无色,色度从3000倍降低到5倍。混凝一吸附法做为一种经济、适用的预处理方法用于处理垃圾填埋场渗滤液是可行的。Landfill leachate is difficult to deal with the waste water,this one adsorption by coagulation pretreatment test results showed that：when the aluminum sulfate dosage 500mg/L,activated carbon dosage 30g/ L,may be infiltration filtrate COD concentration from 1856mg/L reduced to 640mg/L,COD removal rate reached 66%;leachate from the dark brown color into colorless,color-fold from 3000 down to 5 times.Coagulation and Adsorption as an economic one,for the pretreatment method for treating waste landfill leachate is feasible.
