厌氧氨氧化过程的研究进展

Progress in anaerobic ammonium oxidation process

氨的厌氧氧化(Anammox)是近年来微生物学领域的一个新发现。它是指在厌氧条件下,通过特定的兼--N反应转化为N2的过程。国外已对此进行了广泛研究并+-N和NO2性和专性厌氧的自养细菌的作用,将NH4开始应用于废水生物处理中。Anammox工艺与现有工艺相比有明显的优越性。回顾了近年来国际上在厌氧氨氧化方面的研究和应用进展,概要介绍了可能的厌氧氨氧化反应机理、参与的细菌和可行的工艺。

Anaerobic ammonium oxidation (Anammox) is a recent discovery in the microbiology field. It is characterized of certain facultative or strict anaerobic autotrophic bacteria transferring NH4+-N and NO2--N to N2 under anaerobic condition. Anammox process has been widely studied and begun to be applied in biological wastewater treatment. Compared with existing process,Anammox process has obvious advantages. This paper reviews the progresses in fundamental research and application of the anaerobic ammonium oxidation. The possible mechanisms of reaction,the bacteria responsible for Anammox and the recently feasible treatment process are briefly introduced.
