In recent years, anaerobic ammonia oxidation(Anammox), as an economical and eco-friendly nitrogen removal technology for wastewater, has been widely concerned. However, the application of this technology in existing wastewater treatment still faces difficulties, primarily due to the sensitivity of Anammox bacteria(AnAOB)to environmental factors and the insufficient nitrite supply in the reaction system. This article delves into the operating conditions, treatment performance, and stability of Anammox process from both macro(laboratory research, engineering applications, etc.) and micro(AnAOB community characteristics, AnAOB quorum sensing, etc.) perspectives. The analysis focuses on the features, influencing factors, coupling processes, and application of Anammox technology based on domestic and foreign research. Additionally, the article identifies the progress and obstacles of Anammox technology in practical applications. Finally, the article summarizes and proposes research directions and regulation strategies that merit further study to improve and create new coupling processes of Anammox technology for wastewater treatment.
