Abstract

The invention discloses a marsh gas fermentation material and a preparation method thereof, belonging to the technical field of a biological fermentation method for preparing marsh gas. The marsh gas fermentation material comprises a fermentation main material and a fermentation initiator, wherein the fermentation main material is prepared from Flammulina velutipes residue, Enteromorpha, corn straw, fish pond sludge, wheat straw, animal manure and wine stillage; the fermentation initiator is prepared from fish pond sludge, wheat straw, animal manure and strains; the strains comprise Bacteroides succinogenes, Butyrivibrio fibrisolvens, Bacillus subtilis, microzyme, sarcina methanica and Methanosaeta in a ratio of 1:5:3:3:2:2; and the weight ratio of the fermentation main material to the fermentation initiator is (15-19):1. The marsh gas fermentation material fully utilizes the wastes Flammulina velutipes residue and Enteromorpha, and can greatly shorten the start time and increase the gas production quantity and gas production speed in the marsh gas fermentation process.

Description

technical field [0001] The invention belongs to the technical field of biogas preparation by biological fermentation methods, and in particular relates to a biogas fermentation material and a preparation method thereof. Background technique [0002] The algal body is grass-green, tubular and membranous, clustered, with obvious main branches and slender branches, up to 1 meter high. The base is attached to the rock with a fixator, and grows on tidal flats and gravels in the mid-tidal zone. Due to global climate change, water eutrophication and other reasons, the green tide of the large marine alga Enteromorpha broke out. A large amount of Enteromorpha floats and gathers on the shore, blocking waterways, destroying marine ecosystems, and seriously threatening the development of coastal fisheries and tourism. Most types of seafood are widely distributed in oceans all over the world, and some species can also be found in brackish water or rivers. Enteromorpha is a genus of Ch...
