Environmental requirements for establishing a pig manure organic fertilizer production line

Building a pig manure organic fertilizer production line involves several environmental considerations to ensure efficient operation and protect surrounding ecosystems.

Location Requirements

1. Distance from residential areas: Due to odor during production, the site should be at least 500 meters away from homes to minimize impact on residents.  

2. Accessibility: Proximity to roads ensures smooth transport of raw materials and finished products, reducing energy use and pollution.  

3. Terrain and drainage: Choose elevated, flat land with proper drainage to prevent flooding and wastewater leaks during heavy rain.

Air Quality Requirements  

Adequate ventilation is critical. Ammonia and other gases released during processing require ventilation systems that refresh air 6–8 times per hour. This protects worker health and prevents odor buildup. 

Water Management Requirements

1. Wastewater treatment: The organic fertilizer production line must be equipped with complete sewage treatment facilities. Facilities must treat liquid waste from manure to meet local standards (such as COD, ammonia levels) and avoid contaminating water sources.  

2. Water sourcing: Use legal water sources without over-extracting groundwater or disrupting local water supplies.

Land Requirements  

1. Land use compliance: Avoid protected areas like farmland.  

2. Soil stability: Ensure the ground can support heavy machinery to prevent structural issues.

Only by meeting these environmental requirements can we ensure that the pig manure organic fertilizer production line can coexist harmoniously with the environment during construction and operation and achieve green and sustainable development.
