Abstract

The invention discloses a production method of biogas, belonging to the technical field of biomass energy production. The biogas is produced by using the following raw materials in parts by weight: 30-35 parts of pig manure, 40-45 parts of cow dung, 15-20 parts of crop straws, 15-25 parts of mushroom dregs and 10-20 parts of biological bacteria. The production method comprises the following steps of stirring and uniformly mixing the pig manure and the cow dung, and acidizing and settling at the constant temperature of 35-38 DEG C for 10 days to obtain a mixed acidized solution; adding water into the mixed acidized solution to regulate the concentration of the mixed acidized solution to 15%, then, uniformly mixing the mixed acidized solution, the crop straws, the mushroom dregs and the biological bacteria, and fermenting at the constant temperature of 28-30 DEG C; and collecting gases generated in the constant-temperature fermentation process. Compared with the existing biogas production technology, the production method disclosed by the invention has the advantages that the biogas production lasting time is longer, and the biogas yield is higher.

Biogas is various organic substances, at isolated air (reductive condition), and under suitable temperature, pH value, through a kind of combustible gas that the fermentative action of microorganism produces.Biogas belongs to secondary energy, and is renewable energy source.
At present, it is short that existing domestic biogas production technology still rests on the aerogenesis time length, the technological phase that gas production rate is low.
Summary of the invention
The invention provides a kind of production method of biogas, the production method of this biogas effectively can extend the aerogenesis time length of biogas and improve its gas production rate, thus solving existing domestic biogas production technology, to there is the aerogenesis time length short, the low problem of gas production rate.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
It adopts the raw material of following weight part:
Pig manure 30 parts ~ 35 parts, cow dung 40 parts ~ 45 parts, agricultural crop straw 15 parts ~ 20 parts, bacterium slag 15 parts ~ 25 parts and biological bacteria 10 parts ~ 20 parts;
Its production method comprises the following steps:
A, the pig manure of above-mentioned weight part and cow dung to be uniformly mixed, and at 35 DEG C ~ 38 DEG C constant temperature acid precipitation 10 days, obtain mixing acid material liquid;
B, adding water in the obtained mixing acid material liquid of steps A regulates its concentration to 15%, then mixes with agricultural crop straw, bacterium slag, biological bacteria, and at 28 DEG C ~ 30 DEG C ferment at constant temperature;
The gas that C, collection step B ferment at constant temperature process produce.
In technique scheme, technical scheme is more specifically: pig manure 30 parts, cow dung 45 parts, agricultural crop straw 15 parts, bacterium slag 15 parts and biological bacteria 20 parts.
Further, pig manure 33 parts, cow dung 42 parts, agricultural crop straw 20 parts, bacterium slag 25 parts and biological bacteria 10 parts.
