The organic fertilizer granulator plays a key role in the process of treating manure in aquaculture farms, effectively achieving harmless treatment and resource utilization of manure. Below is a detailed introduction to how the organic fertilizer granulator achieves this goal:
1. Reduce environmental pollution
Biological deodorization: In the early stage of organic fertilizer granulation, microbial agents are added to accelerate fecal fermentation, which can effectively degrade harmful gases such as ammonia and hydrogen sulfide, reduce odors, and minimize negative impacts on the environment.
Solid liquid separation: using solid-liquid separation technology, the liquid part is used for sewage treatment, and the solid part is used as granulation raw material, avoiding the waste of water resources and reducing the possibility of water pollution.
2. Kill pathogens
High temperature fermentation: During the composting process, natural heating or a heating system is used to raise the internal temperature of the feces to above 70 ° C for several days, which can effectively kill most pathogens, parasite eggs, and other harmful microorganisms, ensuring the safety of the product.
3. Enhance nutritional value
Nutritional balance: By mixing different types of organic waste, such as cow manure, chicken manure, pig manure, and plant residues, the organic fertilizer processed by the granulator is nutritionally comprehensive, rich in essential plant elements such as nitrogen, phosphorus, and potassium, as well as various trace elements and active substances, which are more conducive to crop absorption.
Stabilization treatment: Organic fertilizers that have undergone sufficient fermentation release nutrients slowly and persistently, avoiding soil salinization problems that may arise from one-time large-scale fertilization.
4. Promote ecological cycle
Closed loop: The organic fertilizer granulator promotes the recycling of livestock and poultry manure, reduces dependence on external fertilizers, lowers the environmental pressure of agricultural production, and helps build a healthy ecosystem.
5. Economic value
Value added conversion: Feces, which were originally considered waste, are processed into high value-added products through granulators, increasing farmers’ sources of income.
Replacing traditional fertilizers: Organic fertilizers can completely or partially replace fertilizers in some cases, reducing fertilizer input and helping to lower costs in the long run.
Practical application
Many large farms at home and abroad have widely used organic fertilizer granulators to treat manure, such as ranches in the Netherlands, Germany, and other places. There are also many successful cases in China. For example, a certain agricultural technology enterprise in Jiangsu has adopted advanced organic fertilizer granulation technology and equipment to convert chicken manure from local farms into organic fertilizer. This not only solves the problem of environmental pollution, but also forms a virtuous cycle system of “planting and breeding integration”, achieving dual economic and ecological benefits.
In summary, the organic fertilizer granulator has made important contributions to the sustainable development of agriculture by not only treating manure from breeding farms, but also achieving harmless and resourceful treatment through a series of scientific methods.
