| 摘 要： | 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。

| Abstract: | On the spot,the removal effect of pollutant NH 4+-N in the mimic sewage by bio-ver-miculite system was studied.The following results were obtained:it was obvious and stable for the removal of NH 4+-N by bio-vermiculite with a removal efficiency over85%.According to the re-moval 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 concentration of dissolved oxygen and the tempera-ture in the solution. |
