摘要
为解决垃圾渗滤液不能达标排放的问题,通过研究聚合氯化铝改性膨润土去除垃圾渗滤液中CODCr的影响因素发现:改性剂溶液的pH值是改性效果的关键因素。用聚合氯化铝改性膨润土处理后,垃圾渗滤液的CODCr浓度低于污水综合排放标准(GB8978-1996)的一级标准限值(COD≤60 mg/L)。
In order to solve the problem of landfill leachate cannot meet the discharge standards issues , the influencing factors that COD Cr in landfill leachate removal efficiency of bentonite modified by PAC were studied , and the result showed that the pH of the modifier was the key factor.After treated by modified bentonite material , the CODCr in landfill leachate was low than I -class criteria specified in Integrated Wastewater Discharge Standard（GB 8978-1996）.
