摘　　要：传统硝化-反硝化技术往往受制于有机碳的缺乏,亟需开发新型生物脱氮工艺。微生物异化Fe(Ⅲ)还原耦合氨氧化称为Feammox,在自养和厌氧条件下以Fe(Ⅲ)为终端电子受体,将NH_(4)^(+)-N转化为稳定、无害的N_(2),为污水生物脱氮提供了一种潜在的选择方案。总结和分析了Feammox的研究进展,论述了该工艺的潜在机理、功能微生物及主要影响因素,展望了后续研究重点和研究方向,为Feammox的更深入探讨提供参考。Traditional nitrification and denitrification technology is often limited by the lack of organic carbon, so it is urgent to develop new technologies to improve the nitrogen removal efficiency. Feammox, which is composed of microbial dissimilatory Fe(Ⅲ) reduction and anaerobic ammonium oxidation, provides a potential option for biological denitrification in wastewater treatment, by using Fe(Ⅲ) as terminal electron acceptor under autotrophic and anaerobic conditions, and effectively converting NH_(4)^(+)-Ninto stable and harmless N_(2). In this review, the research progress of Feammox was summarized and analyzed, and the potential mechanism, functional microorganisms and main influencing factors of the process were discussed. And the research focus and direction were prospected to provide reference for the further discussion.
