AAO工艺反硝化生物滤池中氨氮去除的影响因素研究
Study on Influencing Factors for Ammonia Nitrogen Removal of AAO Denitrification Aerated Filter
摘要
Abstract
[Objective] The aim was to introduce a hydrolytic acidification-anoxic-aerobic ( AAO) process for the treatment of ammonia nitrogen. [ Method ] The technology of biological nitrogen removal and denitriflcation technology was introduced. Effects of some factors like monitoring temperature,pH,DO,SS and time on the removal of ammonia nitrogen were studied,and the optimal experimental conditions were determined finally. [ Result] Methanol should be added into anaerobic tank to supply the carbon source used by denitrifying bacteria for assimilation meitabolism. The anoxic pool of denitrifying bacteria pH was 6. 5 - 8.0 best. Temperature had little effect on denitrifying bacteria. Denitriflcation residence time should be maintained at 8 h. [ Conclusion] The research provides reference for the ammonia nitrogen from urban sewage treatment plant to achieve the new water standard discharge.关键词
