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 composite flocculant was prepared from diatomite added with PFS to pretreat landfill leachate with high pollutant content. The results showed that COD and SS in leachate had the best removal efficiency of 35.0% and flocculant dosage of 7 g / L, PFS content of 80% and reaction time of 20 min, respectively 65.52%, and is not affected by pH.
