【摘要】 采用生物接触氧化法对东江河微污染源水进行脱氮除氨中试研究，在气水体积比为 １：１和采用ＰＷＴ型立体网状填料的条件下，对微污染源水的氨氮、ＣＯＤ、ＳＳ去除率以及填料 表面生物膜中生物量和挂膜情况等运行指标作了分析与观察．试验结果表明该方法工艺具有 较高的氨氮去除能力，氨氮去除率平均可达９０．４％．更多还原

【Abstract】 A test was carried out in a submerged bio-film reactor for disopsal of ammonia-nitrogen (NH3-N) and organic compounds in micro-polluted source water from the Dongjiang River. The indexes, including the removal efficiency of NH3-N, chemical oxygen demand (CODMn) and suspended solids (SS) as well as the growth situation and quantity of mcroorganisms in biological films on surface of PWT-cubic network supporter, were analyzed and investigated as the gas/water ratio was l: 1. The test results showed that the biological beatment process tested in this paper was good in disposal of NH3-N, the average removal efficiency of NH3-N in the raw water was 90.4%.更多还原
