First, warming and promoting corrosion. Non-solar energy design structure of the general biogas digester pool should use cover insulation, in the surface of the biogas digester covered straw, straw, straw, compost or thickening of the soil and other insulation materials, the coverage is greater than the pool surface, to prevent cold air into the pool to reduce the temperature Digging a circular ditch around the digester, stacking the manure in the ditch, and using fermented brewing heat insulation, such as straw is difficult to corrode, can use straw fast rot to accelerate the corrosion of straw, in order to quickly produce gas after entering the digester. It is also possible to build plastic shed insulation if conditions permit. During the refueling and feeding process, inject sewage with a temperature above 20°C, and prevent the inflow of external water to reduce the pool temperature.
Second, increase the concentration. Feeding in time to increase feed concentration to about 15%, and use fresh pig manure, fresh cow dung, fresh sheep manure etc. rich in nitrogen as fermentation raw material, and less use of dry wheat straw, corn stalk and other fiber fermentation raw materials , reduce the carbon-nitrogen ratio difference, accelerate the propagation of methane flora and promote gas production.
Third, fully stir. Under low temperature conditions in winter, biogas digesters are more likely to be crusted and stratified, so it is more necessary to intensify stirring. Every 3-4 days, artificial stirring or biogas slurry reflux stirring, to avoid crusting, stratification, and promote gas production.
Fourth, add inoculants, methanogenic bacteria. Add Gumbol biogas fermenters and old biogas digesters for fast gas production.
