The on-going annual increase in global methane (CH₄) emissions can be largely attributed to anthropogenic activities. However, as more than half of these emissions are diffuse and possess a concentration less than 3% (v/v), physical-chemical treatments are inefficient as an abatement technology. In this regard, biotechnologies, such as biofiltration using methane-oxidizing bacteria, or methanotrophs, are a cost-effective and efficient means of combating diffuse CH₄ emissions. In this review, a number of abiotic factors including temperature, pH, water content, packing material, empty-bed residence time, inlet gas flow rate, CH₄ concentration, as well biotic factors, such as biomass development, are reviewed based on empirical findings on CH₄ biofiltration studies that have been performed in the last decades.

全球甲烷（CH ₄）排放量的持续年度增长在很大程度上可归因于人为活动。但是，由于这些排放物中有一半以上是分散的，且浓度低于3％（v / v），因此物理化学处理作为减排技术效率不高。在这方面，生物技术，例如使用甲烷氧化细菌或甲烷营养菌进行生物过滤，是对抗扩散CH ₄排放的经济有效的手段。在这篇综述中，根据经验回顾了许多非生物因素，包括温度，pH，水含量，填料，空床停留时间，入口气体流速，CH ₄浓度以及生物因素，例如生物量的发展。 CH _4的发现 最近几十年来进行的生物过滤研究。
