Embodiment 1
[0016] Example 1: 5m 3 household biogas digester fermentation to produce biogas
[0017] Take mushroom residue prepared from deer dung from sika deer farms and discarded mushroom sugar in flat mushroom greenhouses, crush the mushroom sugar into granules, the particle size is not more than 10mm, and the mixing mass ratio of deer dung and mushroom residue is 16:7; Organic wastewater was used to adjust the water content of the mixture of deer manure and mushroom residue, and the total solid content of the mixture was controlled to be 6%.
[0018] The amount of zeolite added is 6.25% of the mass of deer dung. The zeolite is processed into granules with a maximum particle size of no more than 20mm. It is wrapped with geotextiles and the length is 100mm lower than the depth of the fermentation material in the fermentation tank. It is fixed at the vertical axis of the fermentation tank.
[0019] The amount of magnetic powder added is 2.5% of the mass of deer dung. The magnetic powde...
Embodiment 2
[0024] Example 2: 15m 3 household biogas digester fermentation to produce biogas
[0025] Preparation method of fermented mixed raw materials: deer manure is directly taken from sika deer farms (households), mushroom slag is made of mushroom sugar, and mushroom sugar is made of mushrooms. , the mass ratio of deer dung and mushroom dregs is 8:5, the water content of the mixture of deer dung and mushroom dregs is adjusted by using organic wastewater, and the total solid content of the mixture is controlled to be 8%.
[0026] The amount of zeolite added as an auxiliary material is 2% of the mass of deer dung. The zeolite is processed into granules with a maximum particle size of no more than 20mm. It is wrapped with geotextiles and the length is 150mm lower than the depth of the fermentation material in the fermentation tank. It is fixed at the axis of the fermentation tank.
[0027] The amount of magnetic powder added as an auxiliary material is 0.5% of the mass of deer dung. T...
Embodiment 3
[0032] Example 3: 8m 3 household biogas digesters
[0033] Preparation method of fermented mixed raw materials: directly take the deer dung from the deer farm, use the mushroom dregs as the mushroom dregs, and use the mushroom roots and mushroom dregs left after pruning the mushrooms. The mass ratio of deer dung and mushroom dregs is 16:5. Organic waste water adjusts the water content of the mixture of deer manure and mushroom residue, and controls the total solid content of the mixture to 7%.
[0034] The amount of zeolite added as an auxiliary material is 5% of the mass of deer dung. The zeolite is processed into granules with a maximum particle size of no more than 20mm. It is wrapped with geotextiles and the length is 100mm lower than the depth of the fermentation material in the fermentation tank. It is fixed at the axis of the fermentation tank.
[0035]The amount of magnetic powder added as an auxiliary material is 1.5% of the mass of deer manure. The magnetic powder i...
