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)。
為解決垃圾滲濾液不能達標排放的問題,通過研究聚閤氯化鋁改性膨潤土去除垃圾滲濾液中CODCr的影響因素髮現:改性劑溶液的pH值是改性效果的關鍵因素。用聚閤氯化鋁改性膨潤土處理後,垃圾滲濾液的CODCr濃度低于汙水綜閤排放標準(GB8978-1996)的一級標準限值(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).
