| 摘 要： | 文章通过对中国南方某给水厂传统水处理工艺中v型滤池去除氨氮的效果进行研究,分析了该厂在长期投加高锰酸钾进行预氧化的同时间接地对天然石英砂滤料改性从而形成生物锰砂滤池的原因.研究结果表明,当进水氨氮浓度大于1.5mg/L时有利于滤料表面挂膜;当氨氮为2.3mg/L时,生物膜表面活性最强;氨氮穿透负荷为17.3mg/L.

| Abstract: | This article studied on the removal effect of NH4 - N by the V - filter of the traditional water technology in some supplying - water works in southern China. Also, it analyzed the reasons that the sand V - filter changed naturally into the biological manganese sand filter when the works carried on the pre - oxidation method of the potassium manganese for a period of time. The findings indicated that it was advantageous to form the membrane in the filter surface when the ammonia nitrogen density was above 1.5mg/L; when the ammonia nitrogen density reached 2. 3mg/L, the biomembrane surface activated strongest; the ammonia nitrogen penetration load was 17.3mg/L. |
