秸秆干式厌氧发酵产CH4技术研究进展与应用OA

The conversion of straw into CH4 is regarded as a key approach to addressing straw-burning pollution and in-creasing the proportion of renewable energy.Among numerous CH4 production technologies,dry anaerobic fermentation of straw has garnered significant attention due to its outstanding advantages:minimal water requirement,lower energy consump-tion,higher CH4 yield,and environmental friendliness.Despite over a decade of development in China,this technology has yet to be deployed on a large scale.This study systematically reviews the mechanisms and key influencing factors of dry an-aerobic fermentation of straw by analyzing domestic and international research results,and summarizes the current applica-tion status of this technology.By synthesizing existing research and successful application cases,this study provides theoreti-cal and practical references for the further development,optimization,and widespread application of dry anaerobic fermenta-tion technology for CH4 production from straw.
