摘　　要：甲烷是一种重要的温室气体,其温室效应是二氧化碳的20倍。近年来,如何有效地利用甲烷以减少温室效应一直是国内外学者关注的重点。研究发现,甲烷氧化菌在有氧的条件下可以对甲烷进行氧化,从而达到利用甲烷以减少温室气体排放的目的。在该过程中,甲烷氧化菌氧化甲烷所产生的有机物作为反硝化反应的电子供体,可用于污废水处理、垃圾填埋渗滤液和生活饮用水反硝化处理,因其廉价且广泛存在而具有很大的研究意义。文中主要阐述了好氧甲烷氧化耦合反硝化过程的研究历史与现状,对甲烷氧化菌的机理、代谢反应过程及反应器做出了详细探讨,总结了迄今为止学者们对于该反应的实验室试验及其反应器的研究,分析了该反应中的主要影响因素。此外,文中对目前存在的问题做出了探讨,对未来的发展前景提出了建议与展望。Methane is an important greenhouse gas.The effect of methane is 20 times than carbon dioxide.In recent years,how to effectively use methane to reduce greenhouse effect has been the focus of scholars in the world.Studies have been found that methane oxidizing bacteria can oxidize methane under aerobic conditions,thereby achieving the purpose of using methane to reduce greenhouse gas emissions.In this process,organic matter produced by methane oxidizing bacteria can be used by denitrifying bacteria as electron donor,which can be used for sewage treatment,landfill leachate and denitrification of domestic drinking water.It is of great research significance because of its low cost and wide existence.The paper mainly describes the research history and current situation of aerobic methane oxidation coupled denitrification process,and discusses methane oxidizing bacteria in detail.It summarizes the researches on laboratory test and its application device of the reaction and the main influencing factor in this reaction.In addition,the paper discusses the existing problems and puts forward suggestions and prospects for the future development prospects.
