垃圾渗滤液深度处理混凝剂的选择

城市垃圾渗滤液废水的处理已经形成一定的规模,但其深度处理至关重要。文章选用三种常见的混凝剂在同等条件下对垃圾渗滤液废水进行处理,结果表明,聚丙烯酰胺PAM在用量最少的情况下,对废水的处理效果最好,但其受pH影响较大,价格比较贵;聚合硫酸铁PFS的处理效果比聚合氯化铁PFC好,虽然处理效果不如PAM,但其价格低廉,是一种不错的废水处理混凝剂。

Choice of Coagulant to Depth Treat Landfill Leachate

Landfill leachate treatment has formed a certain scale,but its depth treatment is very impotent.The paper chose three common coagulants to treat landfill leachate in the same conditions.The results showed that PAM had the best treatment efficiency,but its price was high and its treatment effect highly by pH,so its was not a good coagulant.The treatment efficiency of PFS was better than PFC,its treatment effect lowly by pH,though PFS treatment efficiency not good as PAM,its price was low,and was a good coagulant.
