摘要
探索高效污水生物脱氮技术一直是污水处理领域的热点问题,而对具有将氨氮直接氧化为硝酸盐氮能力的全程氨氧化菌(Complete ammonia oxidizers,Comammox)的发现重新定义了人们对氮循环的认识。如何将全程氨氧化应用于污水处理厂的生物脱氮可能是未来研究需要重点解决的问题。为此,系统地阐述了Comammox菌的微生物学分类、生化特性和代谢机制,分析了Comammox菌与其他脱氮功能微生物的相互作用,总结了Comammox的影响因素。最后提出了基于Comammox-厌氧氨氧化协同实现城市污水主流脱氮的初步设想,并对Comammox的未来研究方向进行了展望。
Exploring efficient biological nitrogen removal technology in sewage treatment has always been the focus of people’s attention.The discovery of complete ammonia oxidizers(Comammox),with an ability to completely oxidize ammonia to nitrate,redefined the understanding of the nitrogen cycle.How to apply Comammox to biological nitrogen removal in wastewater treatment plants may be the basic problem to be solved in future research.The microbial classification,biochemical characteristics and metabolic mechanism of Comammox were reviewed,the interaction between Comammox and other nitrogen‑removing microorganisms was analyzed,and the influencing factors of Comammox were summarized.Finally,a preliminary idea of mainstream nitrogen removal from municipal wastewater using the Comammox-Anammox‑based synergy technology and the prospect of the future research of Comammox are proposed.
