Especially in large agricultural countries, there is a huge amount of agricultural solid waste to be treated every year, and the efficient and comprehensive utilization and harmless treatment of agricultural solid waste should be realized. At present, the resource utilization technology of agricultural solid waste can be divided into microbial technology (aerobic composting, anaerobic fermentation, etc.), physical and chemical technology (incineration, pyrolysis, chemical extraction, etc.) and material engineering technology according to its properties. The resource utilization methods show a diversified trend, mainly in the directions of fertilizer, feed, energy, matrix, industrial raw materials and ecology. Among them, the use of
organic fertilizer production line is a very traditional application method, and it is also the most widely used, most economical and most environmentally friendly utilization method.
The composting link of the
organic fertilizer production line is that the waste is converted into a usable resource with stable organic matter, rich carbon and no pathogens, parasite eggs and weed seeds through the composting system. Its physical properties are completely different from the initial raw materials. The compost product can be used as a soil repair agent or fertilizer, and can also be made into a cultivation matrix or soil cover. According to the supply of oxygen during the composting process, the composting process can be divided into aerobic composting and anaerobic composting.
After composting and fermentation, agricultural solid waste can generally reach the technical indicators of organic fertilizer. However, if it is sold as commercial organic fertilizer, it needs further crushing, screening, granulation, and adding nutrients. The above is the main process of
organic fertilizer production line to treat agricultural solid waste. If you are interested in this, please contact Huaqiang Heavy Industry.
