基于甲烷氧化菌的脱氮技术研究进展

Advances of methanotrophs-based denitrification technology researches

摘要:

甲烷氧化菌利用甲烷作为唯一碳源和能源，在氧化甲烷的过程中能有效地实现脱氮，该过程分为好氧甲烷氧化耦合反硝化(aerobic methane oxidation coupled to denitrification，AME-D)和厌氧甲烷氧化耦合反硝化(anaerobic methane oxidation coupled to denitrification，ANME-D)，在碳循环和氮循环的研究中具有重要意义。本文通过总结近年来有关甲烷氧化菌的分类与分布，阐述AME-D和ANME-D的基本原理、影响因素和应用情况，提出相应的研究方向，以期为甲烷氧化菌在污水脱氮中的应用提供参考。

Abstract:

Methanotrophs can use methane as the only carbon source and energy sourcey to effectively remove nitrogen in the oxidation, which can be divided into aerobic methane oxidation coupled to denitrification (AME-D) and anaerobic methane oxidation coupled to denitrification (ANME-D), and thus, they are of vital significance in the researches of carbon and nitrogen cycles. In this paper, after summarizing the classification and distribution of methanotrophs in recent years, the basic principles, influencing factors and application of AME-D and ANME-D are then expounded, and in the end, the related future trend is analyzed and proposed, in an attempt to make a slightest contribution to the studies of methanotrophs-based applications in wastewater denitrification.
