摘　　要：对膨胀蛭石进行了酸、碱改性实验,研究了膨胀蛭石以及经过酸、碱改性的膨胀蛭石对垃圾淋滤液中总氮、总磷和NH4+-N的去除效果。实验结果表明:酸改性膨胀蛭石对三项指标都有较好的去除效果,对总氮、总磷和NH4+-N的去除率分别为11%,22%和27%;碱改性膨胀蛭石对总氮和NH4+-N的去除效果优于酸改性蛭石,去除率分别为18%和24%。酸、碱改性膨胀蛭石组合处理垃圾淋滤液是可行的。The character of vermiculite was remodeled by acid and alkali. The experimentation prove the acid remodeled vermiculite can remove TN, TP and NH4＋-N of the landfill leachate effectively. The removal effect were 11%,22%和27%. The removal effect of TN and NH4＋-N by the alkali remodeled vermiculite was better than that by the acid remodeled vermiculite. The removal effect were 18%和24%. It＇s feasible for modification vermiculite of acid and alkali to dispose landfill leachate.
