Fe(III) reduction coupled with anaerobic ammonium oxidation is known as Feammox. Feammox, which was first discovered in wetland ecosystems, has the potential to be used in wastewater treatment systems due to its ability to remove ammonium. Feammox can produce N, NO or NO through the reduction of Fe(III) and oxidation of ammonium, which is a potential process to nitrogen loss from aquatic ecosystems and terrestrial ecosystems. The Acidimicrobiaceae sp. A6 was the first Feammox functional bacteria that was successfully isolated from wetlands. The nitrogen removal effect of Feammox can be influenced by many environmental factors, such as pH, organic matter, and different sources of Fe(III). Feammox has broad application prospects, but more exploration is needed to apply this principle to wastewater treatment. This review introduces the development, mechanism, functional microbes and factors affecting the Feammox process, and discusses its potential applications.
三价铁还原耦合厌氧氨氧化作用被称为 Feammox。Feammox 最初是在湿地生态系统中发现的，由于其能够去除氨氮，因此具有在废水处理系统中应用的潜力。Feammox 可以通过三价铁的还原和氨氮的氧化产生 N2、NO 或 NO3-，这是水生生态系统和陆地生态系统中氮损失的一个潜在过程。酸杆菌属 A6 是第一种从湿地中成功分离出来的 Feammox 功能细菌。Feammox 的脱氮效果会受到许多环境因素的影响，如 pH 值、有机物和不同来源的三价铁。Feammox 具有广阔的应用前景，但需要进一步探索将这一原理应用于废水处理。本文综述了 Feammox 工艺的发展、机制、功能微生物及影响因素，并探讨了其潜在的应用。
