摘　　要：以加入聚合硫酸铁(PFS)的硅藻土制备成复配絮凝剂,用于高污染物含量垃圾渗滤液的预处理。结果表明,复配絮凝剂投加量为7 g/L、PFS的质量分数为80%、反应时间为20 min时,对渗滤液中COD和SS去除效果最好,去除率分别达到35.0%和65.52%,且受pH影响不是很大。The diatomite was added into PFS to prepare compound flocculant, which was used on pretreatment of high concentration landfill leachate. The result showed that removal efficiency of COD and SS was 35.0% and 65.52% respectively when PFS content of compound flocculant was 80%, dosage was 7 g/L, and reaction time was 20 min. In addition, pH has no big influence on the results.
