Abstract

The invention discloses a method for producing marsh gas by utilizing corn cob fungi slag as a raw material through anaerobic fermentation. The method comprises the following steps: mixing the fungi slag wasted after corn cob is used as a main raw material to cultivate edible fungus with pig manure or cow dung, adding a methane reagent, and carrying out pile fermentation; and putting fermentationraw materials in a household methane-generating pit or an anaerobic reactor, wherein the addition amount of the raw materials is 80-130 kg per cubic meter of pit volume. In the invention, generation of methane via anerobic fermentation is achieved by carrying out reasonable proportioning, pretreatment, pile outside the pit, fermentation starting and the like on the fermentation raw materials, thereby effectively solving the problem that the pollution is caused by discarding the fungi slag at random and simultaneously turning waste into wealth. After the method is utilized, the gas can be normally generated by the fungi slag in the household, and the method is simple with no need of special equipment and can be applied and disseminated in edible fungus cultivating households.

Description

technical field

[0001] The invention relates to a method for producing biogas by anaerobic fermentation using corn cob slag as a raw material, and belongs to the technical field of comprehensive utilization of agricultural waste. Background technique

[0002] Cultivation materials for edible mushroom production mainly use agricultural and sideline products such as cottonseed hulls, sawdust, straw, corncobs, distiller's grains and crop straws as the main raw materials. During the production and cultivation of edible fungi, a large amount of waste cultivation materials, namely fungal residues, are produced. If calculated according to 70% biological efficiency, about 6 million tons of edible fungus wastes are produced in my country every year. Due to the low pH value of the fungus residue, it cannot directly fertilize the field. The natural dumping of these wastes in the environment will breed a variety of harmful organisms of edible fungi, such as various molds, mosquitoes, mi...
