A Review on Artificial Enrichment and Application of Denitrifying Anaerobic Methane Oxidizing Microorganisms

叙述了近年来硝酸盐与亚硝酸盐型反硝化型甲烷厌氧氧化脱氮微生物的代谢机理、自然分布、人工富集、以及应用研究的最新进展。综合反硝化型甲烷厌氧氧化微生物的特性以及生物脱氮的应用前景,分析了影响反硝化型甲烷厌氧氧化工艺性能的主要因素,并针对反硝化型甲烷厌氧氧化功能微生物与工艺所面临的技术难题提出了研究方向,如自然环境下功能微生物的高精度原位观测,富集过程中微生物生态变化,运行参数和反应器的优化等。

The metabolic mechanism, natttral distribution, artificial enrichment and application research progress of nitrate and nitrite denitrifying anaerobic methane oxidizing micrborganisms were reviewed. The major influence factors of DAMO process were systematically analyzed and discussed on the basis of combining the microbe properties and application prospect in biological nitrogen removal （BNR） field pf DAMO. The concrete research direction have been also proposed in this paper with respect to the existing technical problems of both DAMO microbe and process, such as situ observation of DAMO microorganisms in natural environment, the microbial ecology in the process of enrichment and the optimization of operation parameters and reactors.
