Biogas is an ecological resource for sustainable use. The use of biogas can save a lot of straw, hay and other materials, help to ferment more animal feed and make more paper; biogas can also be used for cooking, lighting, power generation, etc., which greatly saves the expenses of farmers' families Reduce the burden of life; the remaining biogas residue and biogas slurry can be used as organic fertilizer for fertilizing crops and fields, increasing the resistance of crops, reducing the incidence of pests and diseases in crops, and promoting the absorption of nutrients, improving The compaction of the soil keeps the fertilizer and water intact. However, various problems often arise during the use of biogas, affecting the use of biogas and its use.
1. Problems in using biogas resourcesThe shortage of resources for biogas and the types of raw materials for biogas fermentation have plagued farmers. In fact, in daily life, the development and utilization of raw materials for biogas is very extensive. There are straw, hay, leaves, activated sludge, organic waste, municipal solid waste and domestic sewage, industrial organic waste, livestock and poultry manure, etc. All of them can be used as biogas fermentation raw materials, most of which are easily available (such as straw and excrement), and the cost is not high. They are deeply loved by the farmers.
2. How to do the fermentation of biogas digesters?Many people react to the fermentation of straw and pig manure in a digester. Straw is difficult to digest, in which lignin, fiber, etc. are difficult to be decomposed, resulting in difficult fermentation, and pig manure is difficult to ferment after entering the pool. It has been shown by relevant persons that analysis of the composition of pig manure has been found to have preservatives, insect repellent stomach Agents, salt, copper, selenium, phosphorus, soybean meal, rapeseed meal, bone meal, etc., have high contents of some ingredients, and the pigs remain in the pig manure after eating, so that the pig manure contains elements that bactericidal and strongly inhibit the growth and reproduction of methanogens, leading to Fermentation of swine manure is not sufficient, and other toxic gases will be generated. Therefore, if the fast rot of the straw and pig manure is used for rapid pre-treatment by rapid aerobic fermentation, the harmful substances will be precipitated during the pretreatment and the toxic gas will evaporate. At the same time, the destruction of the material (fermentation, softening, rot) can reduce the start-up time by more than half, and then put the fermented straw and pig manure into the biogas digester, which can greatly reduce the decay time and advance the biogas into the gas production stage. It saves more than 60% of the time compared to natural stacking, saving a lot of manpower time costs.
3. What should I do if the biogas digester fails to produce normal gas or produce less gas and produce gas?In normal temperature fermentation process, biogas fermentation is closely related to temperature, and temperature is the key to gas production. Within a certain temperature range, the higher the temperature, the greater the gas production. Adding the biogas fermentation agent to the biogas digester can speed up the temperature-increasing fermentation. To a certain extent, it can solve the problem of low temperature and affect the output of biogas. The Golden Biogas biogas fermentation agent contains high bacteria and has a rapid effect. Jinbao Biogas Fermenting Agent contains more than 300 strains, each containing more than 200 million bacteria, of which anaerobes account for 50%. When conditions are right, they breed at an alarming rate. It can reproduce tens of generations or even hundreds of generations in minutes, thereby accelerating the decomposition of organic matter and greatly increasing the rate of gas production. Generally, gas can be produced within three to five days, and a large amount of gas can be produced after seven days, which is earlier than that without biogas fermentation agent. The production of gas for ten to thirty days can also reduce the amount of biogas volatilization during fermentation of raw materials for biogas fermentation outside the pool, increase the unit gas production rate of biogas fermentation raw materials, and can increase gas production by 30 to 50%.

The way that you kit-out your greenhouse is what will really make it work well for you. The most basic is the Frame and Area - put simply the more surface area and using life of Frame and Area you have, then the more accessories you can fit into your greenhouse and therefore the more capacity you have. Other accessories such as Galvanized Steel Pipes, Greenhouse Film Electric Roll Up and Film Manual Roll Up, Greenhouse Wiggle Wire and Lock Channel , Greenhouse Support Line and Mulch Film ,Ventilation and Sun-Shading Systems can complete your setup.
