| 摘 要： | 通过沉淀槽与生化槽串联的试验系统，分析了微污染水源水生物接触氧化处理工艺启动过程氨氮和亚硝酸盐氮的变化规律。研究结果表明，在无暴气条件下和曝气条件下，填料上硝酸盐细菌的生长均依赖于亚硝酸盐细菌转化氨氮为亚硝酸盐氮的过程。启动中氨氮去除效果趋于稳定的过程是两类硝化细菌在生长速率和转化能力上趋于稳定的过程。提供生化槽充足的曝光气量是保证填料上硝化细菌稳定生长，顺利完全启动过程的必要条件。

| Abstract: | The variations of ammonia nitrogen and nitrite nitrogen during startup of the biological contact oxidation process for treating slightly polluted source water have been analyzed by using the experimental system with the sedimentation tank and the biochemical tank in series.The research results showed that the growth of Nitrobacter always depended on the conversion of ammonia nitrogen to nitrite nitrogen by Nitrosomonas under both no aeration and aeration.The startup during which ammonia nitrogen removal approached the steady state was such a stage,during which the growth rates and conversion capacities of two groups of nitrifying bacteria approached the steady state,respectively.Sufficient air supply for the biochemical tank was necessary for the steady growth of nitrifying bacteria on the packing materials and the smooth completion of process startup. |
