研究了生物蛭石柱对模拟城镇生活污水中污染物氨氮的去除效果。结果表明，生物蛭石柱对NH4^＋-N去除效果与空白蛭石柱去除效果相比明显且稳定，去除率大于85％。从机理分析，生物蛭石柱对NH4^＋-N的去除主要依靠离子交换吸附和生物硝化的协同作用。蛭石挂膜迅速，挂膜后生物蛭石的硝化作用明显。

On the spot, the removal effect of pollutant NH4^＋ - N in the mimic sewage by bio - vermiculite system was studied. The following results were obtained： it was obvious and stable for the removal of NH4^＋ - N by bio - vermiculite with a removal efficiency over 85%. According to the removal mechanism, ion exchange adsorption and nitrification by microbe were the main reasons. The vermiculite could be the carrier of biofilm quickly and became the bio - vermiculite, Nitrification intensity of bio - vermiculite was affected by the con...
