In the past, the rural areas were decentralized breeding models, and everyone paid little attention to breeding pollution. Once the breeding farm reached a certain scale, the pollution of livestock and poultry manure in the breeding farm became very prominent.
The fecal pollutants of livestock and poultry are discharged without reasonable use and effective treatment, which has caused great pollution to the rural environment.
Treatment measures for livestock and poultry breeding pollution:
1. Reasonably store manure. Livestock and poultry manure from farms can be used as organic fertilizer for farmland. The manure can be stored reasonably by modern means to make it fully utilized.
2. The formation of a livestock and poultry manure industry chain. If the livestock and poultry manure is to be treated professionally, a professional industry chain must also be formed. Realize specialized production and market-oriented livestock and poultry manure treatment operations.
3. Reasonably use livestock and poultry farming wastes. Livestock and poultry farming wastes can be used as raw materials for biogas. The livestock and poultry farming wastewater can be used as fertilizer to return to the field scientifically to ensure that livestock and poultry farming wastes can be used scientifically and rationally to protect the environment and reuse resources .
The treatment of livestock and poultry manure and the conversion of organic raw materials such as waste into organic fertilizer can bring huge environmental and economic benefits.
The benefits of organic fertilizer to the soil:
1. Organic fertilizer contains a variety of nutrient elements, which is conducive to the balance of soil nutrient ratio, the absorption and utilization of soil nutrients by crops, and prevents soil nutrient imbalance. It can promote the growth of crop roots and the absorption of nutrients.
2. Organic fertilizer contains a lot of organic matter, which is the food for the reproduction of various microorganisms in the soil. The more organic matter content, the better the physical properties of the soil, the more fertile the soil, the stronger the ability to retain soil, water, and fertilizer, the better the aeration performance, and the better the root growth of crops.
3. The use of chemical fertilizers and organic fertilizers can improve the buffering capacity of the soil, effectively adjust the pH, and keep the soil acidic. The mixed use of organic fertilizer and chemical fertilizer can complement each other, meet the nutrient needs of crops in various growth periods, and improve the effectiveness of nutrients.
Introduction to the production process of animal manure organic fertilizer:
Fermentation → crushing → stirring and mixing → granulation → drying → cooling → screening → packing and storage.
1. Fermentation: Adequate fermentation is the basis for the production of high-quality organic fertilizer. The composting machine realizes thorough fermentation and composting, which improves the speed of aerobic fermentation.
2. Crushing: The crusher is widely used in the organic fertilizer production process, and has a good crushing effect on the raw materials.
3. Mixing: After the raw material is crushed, it is mixed with other auxiliary materials and then granulated.
4. Granulation: The granulation process is the core part of the organic fertilizer production line. The granulator is used to produce dust-free granules with controllable size and shape to achieve high-quality uniform granulation.
5. Drying: The dryer makes the material fully contact with the hot air and reduces the moisture content of the particles.
6. Cooling: The cooler reduces the water content of the pellets while reducing the temperature of the pellets.
7. Screening: The powder and unqualified particles in the organic fertilizer production process can be screened out by the drum screening machine.
8. Packaging: The automatic packaging machine can automatically weigh, transport and seal the bag.
