| 摘 要： | 采用聚合硫酸铝铁（PAFS）预处理垃圾渗滤液中的高浓度有机物，为后续的吸附环节及生物处理阶段创造良好的水质条件。试验结果表明，在低投加量的条件下，PAFS投加量在200mg／L、pH为8．0、沉淀时间为40min时，混凝效果最佳，CODcr的去除率可达37．5％。

| Abstract: | This study is made on the removal of CODCr in landfill leachate by means of the pretreatment with Poly Aluminum Ferric Sulfate to create a good condition for the following the adsorption process and biological treatment process as well.The results show that under the condition of the addition of PAFS at about 200 mg/L,pH about 8.0,setting time 40 min,can achieve the best outcome,the removal rate of CODCr is about 37.5%. |
