Abstract

The invention discloses a method for producing biogas by utilizing anaerobic digestion of livestock excrement, which comprises the following steps: S1, manure pretreatment: collecting livestock excrement, blending an excrement pretreatment solution which comprises bamboo vinegar, plant ash and sterile water in a weight ratio of 1: 1: 10, fully stirring, flushing the excrement by using a high-pressure water gun after the stirring is finished; and the method relates to the technical field of biogas production. According to the method for producing biogas by utilizing anaerobic digestion of livestock manure, the excrement is subjected to sterilization and deodorization pretreatment, so that pollution and damage to crops and soil when the manure is used as an agricultural fertilizer in the later period are avoided, the defect of low carbon content of the manure is overcome by adding fermentation auxiliary materials, and meanwhile, the decomposition and gas production speed of the excrement is further increased; meanwhile, by adding the mixed zymophyte liquid, efficient anaerobic digestion can be conducted on the excrement, and meanwhile the excrement can be converted into organic fertilizer.

Description

technical field [0001] The invention relates to the technical field of biogas production, in particular to a method for producing biogas by anaerobic digestion of livestock manure. Background technique [0002] Biogas, the chemical name is methane, as the name implies, it is the gas in the swamp. People often see that in swamps, sewers or cesspools, there are bubbles coming out. If we strike a match, it can be ignited. This is the naturally occurring methane. Biogas is a kind of combustible gas produced by various organic substances through the fermentation of microorganisms under the isolation of air (reducing conditions) and at a suitable temperature and pH value. Biogas belongs to secondary energy and is renewable energy. Manure is a good raw material for producing biogas. Through anaerobic digestion of manure, it can not only avoid the pollution of manure to the environment but also make full use of it. [0003] The current method of anaerobic digestion of livestock ma...
