摘要
厌氧氨氧化(Anammox)工艺因其脱氮效率高无需碳源与氧气、污泥产量少,近年来在主流污水处理工艺中受到越来越多的关注。该文系统地介绍了城市污水处理中基于Anammox的组合工艺。从季节性温度变化、不稳定的进水条件两个方面讨论了Anammox工艺在城市污水处理中的应用挑战。而后从亚硝酸盐的稳定获取、厌氧氨氧化菌的保留与富集以及微环境的改善等3个方面总结Anammox城市污水处理系统稳定性增强控制策略,展望了该领域未来的发展前景和研究重点以推动主流Anammox的广泛应用。
Anammox(anaerobic ammonia oxidation)process has attracted more and more attention in the mainstream municipal wastewater treatment in recent years because of its high nitrogen removal efficiency,no carbon source and oxygen,and less sludge production.This review first systematically introduces the combined process based on Anammox for municipal wastewater treatment,and then discusses the challenges in the application of Anammox process in municipal wastewater treatment in view of seasonal temperature variations and undulating influent conditions,and summarizes the stability enhancement control strategy of mainstream Anammox from three aspects including stable production of nitrite,retention and enrichment of Anammox bacteria and improvement of micro-environment.Finally,the future perspectives and research priorities in this field are outlined to facilitate the wide application of mainstream Anammox.
