Scarlet Biogas Digester Biogas fermentation technology

1. Fermentation raw materials The raw materials for the production of biogas from fermentation are extensive. Any organic matter such as human excrement, livestock excrement, orange stalk, grass, etc., as well as sewage from starch factories, sugar factories, and alcohol plants can be fermented to produce biogas. However, oils, poisons, and bactericidal drugs cannot be fermented in the pool.
Second, fermentation conditions 1, biogas digester must be closed. Methane bacteria are anaerobic bacteria, and their entire life activities (growth, development, reproduction, etc.) do not require oxygen. On the contrary, oxygen is harmful to it. Therefore, the biogas digester should be closed and there should be no leakage of air leaks. Otherwise, the vitality of the biogas can be impaired.
2, the appropriate water. The proper proportion of water in the fermentation tank is a key to the normal production of biogas. Generally, the moisture content of the material may be determined. If the material moisture content is 60%, then a pound of material is required to add 3 to 4 pounds of water. In short, the higher the proportion of water in the feed, the lower the added water, and vice versa.
3, the appropriate temperature. Biogas bacteria, like other microorganisms, have a suitable temperature range. Generally above 8°C, methane bacteria can move and produce a small amount of biogas. From 20 to 24°C, normal activity, 28 to 30°C, is the most vigorous and the highest rate of biogas production occurs.
4, pH. The suitable range of pH for biogas fermentation is between 6.5 and 7.5. The optimum is 6.8 to 7.
5, stirring. With proper stirring, the gas production rate in the fermentation tank can be increased. Generally use coarse wood or long handle to stir 2 times a week.
6, inoculation. Biogas species are widely found in the sinking sand of the ditch, pit, and the bottom of old biogas digesters. When the biogas is fermented in the primary pool, the sludge sinks can be used as inoculants to increase the number of biogas bacteria and achieve rapid fermentation and biogas production.
Biogas fermentation in the primary pool, with particular attention to methodological issues. A 6m3 new fermentation tank, the first feeding (pig) 500 pounds, 1500 pounds of manure, fermentation for 5 to 7 days, and feeding 1000 to 1500 pounds, adding 4,000 pounds of water, after 5 days of fermentation, sealing the movable cover and other pipes, After every day or every other day to feed 20 pounds, 40 pounds of water, until the barometer to 2 to 3 degrees, you can try burning.
