摘要:从电子传递机制、微生物活动和影响因子等角度出发，综述铁对厌氧氨氧化过程的影响。结果表明，不同价态的铁作为电子受体或电子供体生成厌氧氨氧化底物促进反应，且产生铁氨氧化(Feammox)、硝酸盐依赖型亚铁氧化反应(nitrate-dependent ferrous iron oxidation, NAFO)等不同反应。同时铁元素对厌氧氨氧化过程中功能微生物富集、血红素含量提升及颗粒化过程均有促进作用，从而明显提升对厌氧氨氧化工艺的处理效果。并总结了最佳的铁投加状态，铁元素加强厌氧氨氧化过程中的最适温度、pH值，为后续的铁元素加强厌氧氨氧化过程的研究提供参考。



Abstract:This paper reviews the effects of iron on anammox process from the perspectives of electron transfer mechanism, microbial activities, and influencing factors. The results show that the iron with different valence statesas electron acceptor or electron donor canpromoteanammox by generating substrate and producing different reactions, such as Feammox and nitrate-dependent ferrous iron oxidation (NAFO). Meanwhile, iron element can promote the enrichment of functional microorganisms, the increase of heme c, and the granulation process, thus obviously improving the treatment effect of Anammox process. This paper also summarizes the optimal parameters such as iron dosing state, temperature, and pH in the process of iron-enhanced Anammox, which can provide reference for future study of iron-enhanced anammox.
