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.
