短程硝化-厌氧氨氧化工艺控制方法与机理分析

Control method and mechanism analysis of partial nitrification-Anammox process

短程硝化-厌氧氨氧化工艺作为一种新型自养生物脱氮技术,在处理氨氮浓度高、碳氮比低的废水方面具有极大的经济优势。目前对于该工艺的启动方式以及高效稳定运行所需要控制的条件尚未进行很好的总结。基于此,对短程硝化-厌氧氨氧化工艺的影响因素、控制与启动进行了机理分析与总结,并对污泥菌群的生化过程进行了阐述,以期为后续开发更加稳定高效的短程硝化-厌氧氨氧化自养生物脱氮新技术提供理论参考。

As a new autotrophic biological nitrogen removal technology,the partial nitrification-Anammox process has great economic advantages in treating wastewater with high ammonia concentration and low carbon to nitrogen ratio.At present,the start-up mode of the process and the control conditions for efficient and stable operation have not been well summarized.Based on this,the influencing factors,control and start-up of the partial nitrification-Anammox process were analyzed and summarized,and the biochemical process of sludge bacteria was described.It was expected to provide a theoretical reference for the subsequent development of more stable and efficient partial nitrification-Anammox autotrophic biological nitrogen removal technology.
