摘　　要：对膨胀蛭石进行了酸、碱改性实验,并研究了膨胀蛭石、酸改性和碱改性膨胀蛭石对垃圾淋滤液中总氮、总磷和NH+4-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NH+4-N的去除率分别为11%、22%和27%;碱改性蛭石对总氮和NH+4-N的去除效果优于酸改性蛭石,分别为18%和24%;证明利用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 NH^＋4-N of the landfill leachate effectively. The removal effect were 11%、22% and 27%. The removal effect of TN and NH^＋4-N by the alkali nmodeled vermiculite was better than that by the acid remodeled vermiculite. The removal effect were 18% and 24%. It＇s feasible for modification vermiculite of acid and alkali to dispose landfill leachate.
