| 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.

| Abstract: | 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 remodeled 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. |
