Biogas composite material

Abstract

The invention discloses a biogas composite material, which is characterized by comprising 70-80kg of excrements of livestocks, 10-15kg of mushroom dreg, 10g of biological bacteria and 5kg of biogas residue by mass. The excrements of livestocks comprise 30kg of dried poultry litter, 10-40kg of dried pig litter and 10-40kg of dried cow litter. The biogas residue is a product which obtained by sediments in a biogas digester through drying and crushing. The biogas composite material has the advantages that the aerogenesis duration is long, the biogas production rate is high, the biogas production speed is fast, the decomposition of cellulose and hemicellulose can be promoted so that the utilization ratio of material can be enhanced, the methane content in biogas is obviously increased, the biogas is convenient for industrialized production and transportation, the usage is convenient for the farmers, the raw materials are easy to be obtained, the rural pollution can be effectively solved, and the waste can be comprehensively used.

Description

technical field [0001] The invention relates to a biogas compound raw material. Background technique [0002] Biogas is a colorless, odorous, poisonous, and odorous mixed gas. Its composition not only varies with the type and relative content of fermentation raw materials, but also varies with fermentation conditions and fermentation stages. In general, the main components of biogas are methane, carbon dioxide and a small amount of hydrogen sulfide, carbon monoxide, hydrogen, nitrogen and ammonia and other gases. Biogas can only obtain high-quality and large-quantity biogas under the conditions of microbial growth and normal operation of the biogas digester. At present, the raw materials for biogas fermentation are mainly solved by farmers raising livestock and poultry. The raw materials are relatively single and insufficient, but the trend of breeding is centralized and large-scale development. In addition, there are more laborers in rural areas, and the amount of farming ...
