摘　　要：近年来新发现的铁氨氧化过程(Feammox)能够在厌氧条件下以三价铁离子[Fe(Ⅲ)]为电子受体将铵根离子(NH4+)直接氧化为氮气(N2)、硝酸根(NO3-)或亚硝酸根(NO2-),能够耦合厌氧氨氧化过程、反硝化过程或铁盐反硝化(NDFO)过程完成污水生物脱氮。铁氨氧化相比传统硝化反硝化过程具有诸多优点,如不需要有机碳源、无需曝气、对重金属有更高的耐受力等。对铁氨氧化的发现过程、反应机制、菌种分布及其在污水生物脱氮领域的应用进行了综述,并在对铁氨氧化脱氮研究现状进行深入分析的基础上,指出了铁氨氧化工艺面临的挑战和可能的研究方向。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 nitratedependant 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 indepth analysis of the Feammox process,the challenge faced and the possible research directions of the Feammox process were proposed.
