【摘要】：厌氧氨氧化(Anammox)以NH_4~+为电子供体,NO_2~-为电子受体,无需经过硝化和反硝化过程直接生成N_2从而实现脱氮,是传统硝化、反硝化脱氮工艺的突破。电子受体是Anammox的关键物质。随着对Anammox的深入研究,发现多种电子受体可在厌氧条件下转化NH_4~+,为Anammox的广泛应用提供了理论支撑。介绍了NO_2~-、SO_4~(2-)和Fe~(3+)作为Anammox的电子受体转化NH_4~+的反应机制,对目前机制分析中存在争议的方面进行了探讨,并对多种电子受体下的Anammox研究进行了展望。
[Abstract]:Anaerobic ammonia oxidation (Anammox) is a breakthrough in the traditional nitrification and denitrification process, which takes NH _ 4s as the electron donor and no _ 2- as the electron acceptor. It can produce N _ 2 directly without nitrification and denitrification process, which is a breakthrough in the traditional process of nitrification and denitrification. Electron receptor is the key substance of Anammox. With the further study of Anammox, it is found that various electron receptors can transform NH4 ~ in anaerobic condition, which provides theoretical support for the wide application of Anammox. This paper introduces the reaction mechanism of Fe~(3 and no _ 2O _ 2C _ 4) as the electron receptor of Anammox, discusses the controversial aspects of mechanism analysis at present, and looks forward to the study of Anammox under various electron receptors.
