生物质固体废物厌氧发酵过程中HS对产CH4作用研究进展

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CH₄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CH₄的调控原理，为减少厌氧发酵系统内HS对产CH₄途径的抑制作用，提高发酵效率的技术研究提供理论支撑.

Mechanism of methane production pathway influenced by humus during the anaerobic digestion

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.
