Biogas is a clean energy produced by fermentation of feces, which can be used to replace fuels such as coal for cooking or generating electricity. Manure is left behind after biogas generation. Manure can be fermented to produce organic fertilizer. It is also quite convenient for organic fertilizer equipment to use biogas to produce organic fertilizer. how to use biogas residue to produce organic fertilizer in organic fertilizer equipment:
1. What are the components of dry biogas residue
Biogas residue is a solid substance left behind after the anaerobic fermentation of livestock and poultry manure to produce biogas. Due to long-term immersion in the biogas digester, the moisture content of the biogas residue can be very high. To produce organic fertilizer, it is necessary to separate the dry biogas residue material through a solid-liquid separator, which contains rich organic matter, humic acid, amino acid, nitrogen, phosphorus, potassium, and trace elements. The organic matter calculated by dry matter is generally above 95%, and other components vary depending on their fermentation materials.
2. What is the role of biogas residue
Biogas residue is mainly used to produce organic fertilizer, and organic fertilizer equipment is used as crop base fertilizer and topdressing. Through the application of organic fertilizer, not only the goal of reducing the amount of chemical fertilizer has been achieved, but also the soil has been improved. Biogas residue can also be used as a nutrient soil for preparing flowers, seedlings, traditional Chinese medicinal materials, and vegetable seedlings.
3. Equipment for producing organic fertilizer from biogas residue
Organic fertilizer equipment The production equipment required for producing organic fertilizer from biogas residue from beginning to end include a solid liquid separator, a dryer, a stacker, a belt conveyor, a mixer, an organic fertilizer granulator, an automatic packaging machine, a biogas slurry delivery pump, a liquid fertilizer storage tank, laboratory equipment, and related ancillary facilities.
4. Production process of biogas residue organic fertilizer
The process of producing organic fertilizer by fermentation with biogas residue organic fertilizer equipment is relatively simple. For example, ordinary organic fertilizer equipment only needs to ferment, crush, and screen the biogas residue separated from the solid and liquid, and then bag it. If biogas residue biological organic fertilizer is to be produced, it is necessary to add microbial strains to increase the efficiency of the fertilizer material. If organic fertilizer is made in granules, it requires more equipment and more processing steps. Of course, the fertilizer produced is also very popular in the market.
