With the development of intensive farming technology, many large-scale farms will focus on manure treatment, and then use organic fertilizer production equipment to process manure to make fertilizer. The harmless treatment of manure can solve the problem of reasonable discharge of poultry manure. What are the main treatment methods of animal manure?
1. Drying treatment. It is the dehydration of feces, which is convenient to use, mainly including natural drying and high-temperature rapid drying. Natural drying is the use of light-dried livestock and poultry manure to dry; high-temperature rapid drying is artificial drying through a dryer.
2. Aerobic composting for organic fertilizer production. Livestock and poultry manure contains a large amount of organic matter and rich nitrogen, phosphorus, potassium and other nutrients, and is a valuable resource for sustainable agricultural development. Therefore, aerobic composting is widely used at present. According to the characteristics of the feces raw materials and auxiliary materials, with the help of a compost turner, the manure is quickly fermented to produce organic fertilizer. General organic fertilizer production line process of commercial organic fertilizer: The general production process of commercial organic fertilizer includes: organic material inoculation fermentation (pre-fermentation), main fermentation, crushing, compounding and mixing, drying, granulation, cooling, screening, Several processes such as metering and packaging. The organic fertilizer production equipment mainly includes fermentation tanks, mixers, overturning equipment, belt conveying equipment, cylinder sieves, pulverizers, organic fertilizer granulator machine, etc.
3. Biogas production. According to the characteristics of high organic matter content in livestock and poultry manure, under certain moisture, temperature (35°C-55°C) and anaerobic conditions, through the catabolism of various microorganisms, flammable mixed gases such as methane and carbon dioxide (biogas) will be produced. Formation, while killing Escherichia coli, insect eggs, etc. in the feces. Biogas is clean energy and can be used as fuel for family life.
