The cold winter is coming soon, and the reduction of biogas production has always been a difficult problem for everyone. In order to improve the biogas production in winter, it is necessary to first understand the environmental conditions of biogas production. Biogas fermentation has a great relationship with temperature, because natural biogas fermentation microorganisms can only grow and reproduce under normal temperature conditions and perform normal metabolic activities. If the temperature is not in its proper range, the growth of the broth will be slow, the vigor will be declining, the anaerobic decomposition and methane production will be slow, and the production gas will be less. So how to increase the gas production of winter biogas?

First of all, the pretreatment of the raw materials is completed. The biogas materials generally include crop stalks, fodder, leaves, and feces. The lignin, cellulose, hemicellulose, pectin, and wax compounds in the straw are destroyed if not treated. It is easy to crust, affect gas production and gas production efficiency. Biogas material pretreatment mainly has the following functions:
1, shorten the gas production time. Straw is difficult to digest, in which lignin, fiber, etc. are difficult to be decomposed, so the straw is quickly pretreated with a fast aerobic fermentation, such as Gem Biogas materials, and then the fermented straw is put into the biogas tank. Save rot time, advance into the gas production phase, save more than 60% of the time than natural heaping.
2, to prevent crusted obstacles. The surface of the straw has a layer of wax that is not easily destroyed by the biogas microorganisms. If the straw directly under the pool will be a large number of floating crust, it is difficult to be decomposed and fully utilized by fermentation, thereby significantly affect the gas production and gas production efficiency, such as before entering the pool with Glyphon biogas fast rot pretreatment after it was destroyed (Fermentation, softening, rot) can increase gas production by 30 to 50%.
3, improve gas production efficiency. After the raw material is pretreated, the fermentation time in the pool is naturally reduced, and the inlet temperature can meet the requirements and start gas production. If the raw material is used together with the Gambo Biogas Fermenting Agent, the startup time can be reduced by more than half and can be increased. 50 to 100% of gas production, gas production is even and stable, and it saves a lot of manpower time and cost.
Second, do a good job of insulation measures. Covering the plastic sheds before entering the winter can increase the temperature of the liquid in the shed and the biogas digester, creating favorable conditions for increasing the gas production of the biogas in the winter. The biogas digesters can provide good management for the farmers throughout the year. However, most farmers have little gas production in the winter biogas digester and can only cook one meal because there is no “covering the quiltâ€. Our current biogas digesters are not equipped with temperature-increasing facilities and cannot artificially increase the liquid temperature in the tanks. Therefore, in order to maintain the temperature of the biogas digester liquid, it is necessary to timely cover the pen housing film in the late October (when the temperature is above zero degrees or before the cold current does not arrive), so as to increase the air temperature and the ground temperature in the pens to increase the biogas. The purpose of the gas production in the pool.
Finally, before the onset of winter, raw materials for fermentation in biogas digesters are decomposed by biogas bacteria and gradually consumed or converted. If fresh supplements and strains are not added in time, biogas bacteria will reduce the amount of gas produced because there are not enough raw materials. At this time, you can add Gum Biogas fermentation agent and fresh ingredients. This ensures that the biogas bacteria have a sufficient quantity and food, and can perform normal metabolism, so that the gas production is normal and lasting. It is worth noting that the time for supplementing new materials should be in early October. Therefore, when the ambient air temperature is relatively high, the replacement of new materials can quickly return to normal gas production and increase gas production; Material, it is necessary to extract the number of cubic meters of liquid (If you want to add 2 cubic meters of cow dung, it is necessary to extract 2 cubic meters of liquid), and then from the feed inlet ready to add fresh livestock and poultry manure.
