摘　　要：基于化学絮凝预处理法提升垃圾渗滤液内COD的清除效果,最终确定了PAFCS的最佳配比是4:1,最佳投放量体积比是6:1000,最好pH值是7.0,COD最大清除率能达到51.3%;明确了PASiC的最佳配比是1:4,最佳投入量体积比是6:1000,最好pH值是5.5,COD最大清除率能达到65.2%;明确了PAC与PAM联合絮凝剂的PAC(40g/L)最好投入量体积比是6:1000,PAM(4g/L)最好用量体积比是1.5:1000,最好的反应pH值是7.0,COD最大清除率能达到70.4%。PAC与PAM联合絮凝剂为最佳预治理絮凝剂。Based on the chemical flocculation pretreatment method to improve the removal effect of COD in landfill leachate,input amount and pH value of three kinds of chemical flocculants on the removal effect of cod were analyzed.Finally,the optimal ratio of PAFCS was 4:1,the optimal volume ratio of PAFCS was 6:1000,the optimal pH value was 7.0,and the maximum removal rate of COD could reach 51.3%.The optimal ratio of PASiC was 1:4 The results show that the best dosage volume ratio of PAC(40g/L)and PAM(4G/L)is 6:1000,1.5:1000,7.0 and 70.4%,respectively.PAC and PAM combined flocculant,which is the best pre treatment flocculant.
