1. Harmless treatment: Organic fertilizer equipment decomposes or inactivates pathogens, weed seeds and harmful substances in livestock and poultry manure through high-temperature fermentation and microbial degradation to achieve harmless standards.

2. Waste gas treatment: The equipment is equipped with waste gas treatment devices, such as biological deodorization system, activated carbon adsorption device, etc., which can effectively deal with the odor and harmful gases produced in the fermentation process.

3. Wastewater treatment: Organic fertilizer equipment is usually equipped with wastewater treatment systems to ensure wastewater discharge standards.

4. Solid waste treatment: Organic fertilizer equipment converts livestock and poultry manure into high-quality organic fertilizer, realizing the resource utilization of solid waste.

5. Environmental protection design: Modern organic fertilizer equipment pays attention to environmental protection performance in design, adopts closed structure to reduce dust and odor leakage. For example, equipment such as large wheel compost turning machines and horizontal fermenters are closed in design, effectively preventing the spread of dust and odor.

6. Resource recycling: Organic fertilizer equipment can not only process livestock manure, but also use the processed organic fertilizer for agricultural production to realize the recycling of resources. This recycling model reduces waste emissions and reduces pressure on the environment.

In summary, organic fertilizer production line through harmless treatment, waste gas treatment, waste water treatment, solid waste treatment, environmental protection design and resource recycling and other measures, can effectively reduce or even eliminate the secondary pollution of livestock and poultry manure, in line with environmental protection requirements, promote the sustainable development of agriculture.
