Biogas residue decomposing agent with biogas output synergistic effect and application thereof

Abstract

The invention provides a biogas residue decomposing agent with a biogas output synergistic effect and an application thereof and belongs to the technical field of biotechnology. In the biogas residuedecomposing agent with the biogas output synergistic effect, cellulase and xylanase are capable of enzymatically decomposing the undigested feed residue in the biogas residue, decomposing the crude fiber plant long-chain fibers in the residue into the short-chain fibers easily absorbed and utilized by the microorganism and enzymatically decomposing the plant cell walls in the residue; the releasedxylan and non-starch polysaccharides are hydrolyzed and converted into the monosaccharides, such as glucose, which can be easily absorbed by the microorganism; the monosaccharides, such as the short-chain fibers and glucose, formed in the enzymatic decomposing process can be digested and decomposed under the effects of bacillus subtilis and bacillus licheniformis and the residue and the biogas residue can be further decomposed, so that the effect of quickly decomposing the biogas residue can be achieved.

Description

technical field [0001] The invention belongs to the field of biotechnology, and in particular relates to a biogas residue decomposer and its application. Background technique [0002] Facing the current situation of energy reduction, biogas fermentation is an important method to develop biomass energy. Biogas fermentation is a method with high efficiency and mature technology. It will be of great significance to change the energy structure and reduce dependence on fossil fuels. For example, at Shanghai Xinghuo Farm in Taicang, Jiangsu, the manure of 2,700 dairy cows was fermented with biogas to produce nearly 3,000 m3 3 Biogas can solve the cooking gas of 2,700 households. At the same time, biogas fermentation is also an important treatment method for high-concentration organic wastewater and waste. Biogas fermentation can treat poultry and livestock manure, reduce the accumulation of sewage, and play an important role in environmental purification. [0003] Raw materials ...

AI Technical Summary

Problems solved by technology

[0003] Raw materials for biogas fermentation often use rural livestock and poultry farms to treat animal feces and urine sewage, and anaerobic biogas digesters are generally used for pre-fermentation treatment of animal feces and urine sewage. The main problem is that during the daily use of anaerobic digesters , There are various types of undigested and utilized feed residues in the manure of livestock and poultry animals, which cannot be decomposed and digested by anaerobic bacteria in the biogas tank, and thus deposited in the biogas tank, reducing the anaerobic fermentation efficiency and service life of the biogas tank
