摘　　要：厌氧氨氧化耦合不同的电子受体,是近年来陆续发现的新型生物脱氮方式,不仅在废水生物处理领域备受关注,在氮、硫、铁、锰等地球生物化学循环过程中亦发挥重要作用。聚焦亚硝酸盐型厌氧氨氧化(Anammox)、硫酸盐型厌氧氨氧化(sulfate-reducing ammonium oxidation,Sulfammox)、铁氨氧化(Feammox)和锰氨氧化(Mnammox)等4种不同电子受体型厌氧氨氧化过程,对其反应过程机制及反应方程式进行分析和总结,并从不同类型厌氧氨氧化菌的系统发育多样性及代谢特性等方面进行综述、阐明不同电子受体型厌氧氨氧化技术及其功能微生物的研究现状,探讨其应用瓶颈及未来的发展方向,以期为后续的深入研究提供理论依据,为推动不同电子受体型厌氧氨氧化技术的发展及在废水脱氮领域的应用提供思路。Anaerobic ammonia oxidation coupled with different electron acceptors is a series of novel biological denitrification approaches reported in recent years,which has not only attracted much attention in the field of wastewater biological treatment,but also played a crucial role in geochemical cycles of nitrogen,sulfur,iron,and manganese.This paper focused on four anaerobic ammonia oxidation processes coupled with different electron acceptors,including nitrite-dependent anaerobic ammonia oxidation,sulfate type anaerobic ammonia oxidation(Sulfammox),anaerobic ammonium oxidation coupled to Fe(Ⅲ)reduction(Feammox)and anaerobic ammonium oxidation mediated by MnO 2(Mnammox).The reaction mechanisms and reaction equations were summarized and the phylogenetic diversity and metabolic characteristics of different anaerobic ammonia oxidizing bacteria were reviewed.The research progress and functional microorganisms of anaerobic ammonia oxidation processes coupled with different electron acceptors were elucidated.Finally,the application bottlenecks and the future development were discussed.The aim was to provide theoretical support for further in-depth research,and to provide a new perspective for promoting the development of anaerobic ammonia oxidation technology with different electron acceptors and the application in the field of wastewater denitrification.
