When the methane in the methane tank is not enough, there is no use of water in the pond
Should do the following points: 1, biogas pool should wash the ground, feeding fermentation raw material mixture into the digester biogas by bacterial fermentation to produce biogas, nutritional components in raw material will gradually be consumed or converted, if not promptly added fresh raw materials, methane bacteria will "do not have enough to eat, eat well, production the gas will decrease. In order to keep the bacteria have enough food, so that the normal production of gas will continue to add fresh raw materials. When the methane tank feeding should be the first material, material, how much to do, in order to maintain the volume of the tank. If the feed is fed only for a long period of time, the volume of the tank will be filled by the fermentation liquid without the use of methane. 2, often mixing the fermentation raw materials in the methane tank fermentation raw materials and biogas bacteria uniform contact, in order to ensure normal fermentation gas production.
The safe fermentation of methane tank should pay attention to the problem in the marsh gas pool, when the bacteria are exposed to harmful substances, they will be poisoned. Therefore, in the daily management, don't make the mistake in the tank into the following hazardous substances: all kinds of highly toxic pesticides, especially organic fungicides, antibiotics, insect repellent; heavy metal compounds, toxic industrial waste water and salts; just sterilized manure; spraying the crop stems and leaves of various plants can make pesticide; soil pesticides such as peach leaves, neem leaf; spicy foods such as onions, garlic, pepper, leek, radish seedling; washing powder, laundry water can not enter the biogas pool. If found to be poisoned, the fermentation liquid inside the pool to take out half, and then put half of the new material, in the production of gas emptying 2 - 3 days to normal gas production. Three. To improve the biogas production rate of biogas digester, the fermentation process should be controlled and adjusted to maintain the stability of the fermentation gas production, so that the biogas production is good and the gas production is prosperous. To achieve the above effect,
The fermentation of biogas fermentation materials suitable is the material basis to produce biogas digesters, in order to ensure the start and fermentation fermentation of raw materials sufficient and stable, in before feeding, fermentation of raw materials need to choose the suitable organic nutrition of cattle and pig manure, sheep manure and so do the start. These raw materials are fine particles, containing a lot of low molecular weight compounds, carbon and nitrogen ratio is less than 25:1, which is suitable for the fermentation of carbon and nitrogen ratio, after entering the pool to start fast, good gas production. Do not start with chicken manure, manure, these raw materials in the case of less methane bacteria, the material is easy to acidification, fermentation can not be normal. The fermentation concentration of 3, the first loading the biogas digesters to fit the first feeding amount should be 80% if the volume of the pool, because of the temporary lack of raw materials, one-time feeding can not meet the requirements of feeding quantity (most household biogas digester will not have such ample raw materials), and more than the water inlet and outlet 15 cm, closed fermentation fermentation. The first feeding concentration using 6%--10%, if the proportion of raw materials and water in the methane tank is difficult to estimate, would rather thin, not too strong, otherwise easy acidification.
It is the start of the biogas fermentation to start the newly built biogas digesters to start the normal and stable process. It is very important to maintain the stable operation of biogas digester if it can start smoothly. Therefore, in order to make the biogas production of new built quickly, gas production, installation materials should meet the following requirements: 1, adding a sufficient amount of inoculum to collect old biogas pool, biogas residue and biogas slurry pit, FWFPM, black bottom sediment of urban sewage ditch sludge, sewage sludge in slaughterhouses the new pool charging before or after feeding, these substances containing rich methane bacteria, inoculation quantity to reach 10 - 30% of the fermentation of raw materials, the inoculum and the raw materials are mixed evenly, join in the pool.
