厌氧氨氧化生物脱氮技术的研究进展

厌氧氨氧化是指在厌氧条件下，厌氧氨氧化混合菌直接以NH4 为电子供体，以NO3-或NO2-为电子受体，将NH4^ 、NO3-或NO2-转变成N2的过程。厌氧氨氧化作为一种新型的污水处理工艺具有较高的理论意义和良好的应用前景。本文主要阐述了厌氧氨氧化生物脱氮技术原理、厌氧氨氧化的可能途径、方法及其应用现状，并且讨论了厌氧氨氧化反应的微生物学机理和厌氧氨氧化工艺的开发，提出了今后研究的主要方向。

Advance in anaerobic oxidation of ammonium for biological removal of nitrogen

The anaerobic ammonium oxidation microbiology can convert ammonium to dinitrogen gas with nitrite or nitrogen dioxide as electron acceptor. As a new method of water treatment, anaerobic ammonium oxidation may be of good applied prospect. The principle, the possible path, the method and the applied status of anaerobic ammonium oxidation were introduced, including the mechanism of microbiology, the development of technology and the direction for future research.
