摘　　要：硝态氮/亚硝态型厌氧甲烷氧化(NOx-DAMO)过程在还原硝酸盐/亚硝酸盐的同时将甲烷氧化为二氧化碳,在全球碳氮循环中起着重要作用。从应用的角度看,利用NOx-DAMO原理进行环境中甲烷和氮素污染控制也值得关注。本文介绍了在MBR和MBfR等反应器中应用NOx-DAMO过程单独或与其他工艺联合处理模拟废水和实际废水的研究中,污染物去除速率和效率显示出了工程实用价值。指出基于NOx-DAMO原理开发垃圾渗滤液和填埋气协同处理工艺、煤层气厌氧生物氧化工艺的研究值得探索,其可能为无规模利用价值的生活垃圾填埋气和煤层气的处理提供低成本和环境友好的解决方案。今后的研究方向应该是在继续深入NOx-DAMO微生物的生理特性研究的同时,需要面向不同应用需求广泛开展工艺开发与优化研究。The nitrate/nitrite-dependent anaerobic methane oxidation(NOx-DAMO)process plays an important role in the global carbon-nitrogen cycle by reducing nitrate/nitrite and oxidizing methane to carbon dioxide.From the application point of view,using NOx-DAMO principle to control methane and nitrogen pollution in the environment is worthy of attention.The application of NOx-DAMO process in membrane bioreactor,membrane biofilm reactor or combined with other bioprocess for wastewater treatment have gained many progresses.The removal rate and efficiency indicated its potential in practical application.Based on the principle of NOx-DAMO,it is promising to utilize this bioprocess in the simultaneous treatment of landfill leachate and landfill gas or coalbed methane.The novel NOx-DAMO process can provide low cost and environmentally friendly contaminant treatment strategy for methane without scale utilization value.While studying on the physiological characteristics of NOx-DAMO microorganisms,it is necessary to pay more attention on technology research for different demands.
