Applying organic fertilizer is beneficial to environmental protection. The eutrophication of the water environment in China mainly comes from the discharge of solid organic wastes into the water body, and the discharge of fertilizer nutrients from farmland only accounts for a small proportion. At present, the eutrophication degree of the water environment in China’s lakes is still very serious. For Taihu Lake, Dianchi Lake, Chaohu Lake, Dongting Lake, Poyang Lake and other lakes, cutting off the input of organic and inorganic nutrients into the water body is the only way to achieve the prevention and control of water eutrophication. The development of organic fertilizer industry and the protection of water environment in the development of fertilizer industry is a great cause that combines fertilizer industry, soil fertility and water environment protection, high quality and high yield of crops.
The process flow of manure organic fertilizer production line is as follows: after the fermentation of organic fertilizer raw materials (animal manure, domestic garbage, dead branches and leaves, biogas residue, waste bacteria, etc.), they enter the semi-wet material crusher for crushing, and then add nitrogen, phosphorus and potassium (pure nitrogen, phosphorus pentoxide, potassium chloride, ammonium chloride, etc.) to make
