Abstract:
Recently, the newly discovered Fe(Ⅲ) reduction coupled to anaerobic ammonium oxidation (Feammox) process, which can convert ammonium (NH4+) to N2, nitrate (NO3-) or nitrite (NO2-) with Fe(Ⅲ) as the electron acceptor under anaerobic conditions, can fulfill the biological nitrogen removal by combining with ANAMMOX process, traditional denitrification process or nitrate-dependant Fe(Ⅱ) oxidation (NDFO) process. Compared with the traditional denitrification, there are lots of advantages of Feammox process, such as needlessness of organic carbon source and aeration, higher tolerance to heavy metals. The discovery, the mechanism, the strain distribution and its application in biological nitrogen removal from wastewater were reviewed. Furthermore, based on the in-depth analysis of the Feammox process, the challenge faced and the possible research directions of the Feammox process were proposed.
