摘　　要：针对生物质固体废物量大面广,具有污染和资源利用双重特性,厌氧发酵能源化可促进其污染控制,且过程中部分有机成分在微生物作用下转化成腐殖质(HS).通过分析厌氧发酵过程中HS转化规律、HS结构特征与氧化还原性能、腐殖质还原菌与产甲烷菌活性、产CH_4效率之间的响应关系和作用机制研究进展,总结凝练出生物质厌氧发酵系统内HS对CH_4的调控原理,为减少厌氧发酵系统内HS对产CH_4途径的抑制作用,提高发酵效率的技术研究提供理论支撑.Biomass solid waste quantity was large and widely available,with dual characters of pollution and resource.Anaerobic fermentation could promote its pollution control and some part of components involved were converted into humus(HS)under the action of microorganisms.By analyzing the relationship between HS conversion,HS structural characteristics and redox performance,humic reducing bacteria and methanogen activity,and CH4 production efficiency in anaerobic fermentation,the regulation principle of HS to CH4 in biomass dry anaerobic fermentation system was illustrated,which provided theoretical support for reducing the inhibition of HS on the CH4 production pathway and improving fermentation efficiency in anaerobic fermentation system.
