How to make biogas digesters more productive in the winter? In the current biogas fermentation process, various raw materials are complicated and the conditions are not the same, resulting in slow start of the biogas digester, low gas production, and low gas production rate. Especially in the low temperature conditions in winter, the gas production rate cannot meet the requirements for use. Fuld Microbial Biogas Fermenting Agent is a biogas-specific production-promoting additive researched and developed using Japanese biotechnology. It can speed up the temperature-raising fermentation, quickly start the pool, double the gas production rate and gas production rate, successfully solve the previous biogas digester biogas from the straw used in rural biogas due to slow start of biogas, low gas production, slow gas production, decomposition rate Low, serious crusts and difficult discharge problems. Rationale Biogas digesters go through three stages: liquefaction, acid production, and methanogenesis. Liquefaction stage: Extracellular enzymes (such as cellulase, peptidase, lipase, etc.) secreted by microorganisms in Fuld Microbial Biogas Fermentation Agent break down crop stalks, human and animal feces, garbage, and other organic wastes into soluble form. The small molecule compounds in water, namely polysaccharides, break down into monosaccharides or disaccharides; proteins break down into peptides and amino acids; and fats break down into glycerol and fatty acids. Acid production stage: The monosaccharides, peptides, amino acids, glycerol, fatty acids and other substances are converted into simple organic acids (such as formic acid, acetic acid, propionic acid, butyric acid, and
Lactic Acid) and alcohol (such as Methanol, ethanol, etc.) as well as carbon dioxide, hydrogen, ammonia, and hydrogen sulfide. Subsequently, these organic acids, alcohols, carbon dioxide, and ammonia are used by methanogenic microbes (also known as methanogenic bacteria). Methanogenic bacteria decompose acetic acid, alcohol, etc. to form methane, which is called the methanogenic stage. In the first two phases, microorganisms will release chemical heat during their action. Therefore, the fermentation tank will heat up. Fuld Microbial Biogas Aid will play a catalytic role in the whole process to achieve rapid gas production and gas production. More, the complete decomposition of raw materials. Method of use Method One: Improvement of the old pool with low gas production There are many reasons for the low gas production in the biogas digester, the most important of which is the reduction of functional microbial activity. In accordance with the amount of 0.5 kg per cubic meter of fermentation agent, diluted with fecal water or biogas slurry from the feed inlet, and then repeatedly remove the biogas slurry feed inlet to make it as far as possible mix. Then seal it. Method 2: Construction of a new pond (reference procedure) 1. Pulverization: Crush the straw (corn stalk, rice straw, wheat straw, etc.) with a pulverizer, and the particle size is 1.5-3 cm, and the 8-10 cubic meters pulverize 300-400 kg of straw. 2. Wetting: The crushed straw is added with water (preferably manure), and the amount of water added per 100 kg of straw is 100-120 kg. The wet time is about one day. 3. Mixing: Wet straw is mixed with the starter. 8 cubic meters of biogas microbial agent dosage 4 kg, add water (preferably manure or biogas slurry) diluted to 100 kg. The best amount of feces (chicken and cow dung) is 500 kg, which is fully mixed with wet straw. (Hold your hands tightly to ensure that the moisture content is 60%-70% with a small amount of water droplets.) Visually observe that no water can flow from the ground. 4. Biological pretreatment: outside the pond pretreatment: the straw is mixed and the width is 1.2-1.5 meters, height 1-1.5 meters, covered with plastic film, biological pretreatment time, summer 3-4 days, winter 4 - 6 days, under normal circumstances when the heap temperature reaches 50 °C and maintain 3 days, the heap of straw within the white hyphae into the pool. In-pool pretreatment: Mix the stalks into an anhydrous biogas digester for biological pretreatment, pay attention to the proper practicability of the raw materials, and cover the wells in the pool. (Note: Before entering the pool, straw raw materials are packed into mesh bags for future discharge.) 5. Inoculation: The biopretreated straws packed in mesh bags should be put into the pool and inoculum should be added. The amount of inoculum added is 20%-30% of the content. Mix well with biogas fermentation agent 2.5 kilograms, and add water to the conventional capacity of the digester (total solids concentration is 6%-8%). If dry fermentation process is used, straw will not need to be added after biological pretreatment, and inoculum can be added. . 6, start: sealed digester pool mouth, and then continue to air 1-3 days, from the second day of deflation began to test the fire, until it can ignite and the flame stability, you can use it normally.
