Abstract：Iron ammonia oxidation, also known as Fe(III) reduction coupling with anaerobic ammonia oxidation technology has the advantages of low sludge yield, no need for organic carbon, and tolerance to heavy metals. In this review, the potential mechanisms of Feammox, iron reduction pathways and functional microorganisms are described. And key influencing factors including pH, temperature, source of Fe(Ⅲ), organic matter as well as nitrates and nitrites are discussed. From the perspective of coupling Feammox technology with other nitrogen removal processes, the latest development trend of Feammox technology in wastewater treatment applications is reviewed, and the future development is prospected. An overview of the latest developments in the Feammox process provides valuable information for further process optimization and contributes to better nitrogen removal performance in future practical applications.
