Odor emissions from organic fertilizer production lines have always been a headache, but there are natural methods to tackle the problem effectively.
Raw Material Selection
Start by being strict with raw material choices. Prioritize fresh, low-odor materials. For example, fresh plant residues produce far less odor compared to materials that have already started rotting.
Improve Production Management
- Adopt dry manure removal processes: During livestock farming, use dry manure removal methods to reduce moisture content in feces. This cuts down on odor during fermentation.
- Clean and transport promptly: Regularly clean up manure and organic waste in fermentation workshops and storage areas to prevent long-term buildup. Also, move finished compost out quickly to minimize lingering odors at the production site.
- Maintain equipment: Service organic fertilizer production line equipment regularly to prevent leaks and odor issues caused by malfunctions.
Use Natural Deodorizers
- Plant extracts: Some plant extracts, like yucca extracts, contain compounds that bind with ammonia, effectively reducing odor from manure.
- Microbial agents: Add specific microbes (such asodor-eating bacteria) to break down smelly substances like ammonia and hydrogen sulfide at the source.
Physical Odor Control
- Seal and ventilate: Build sealed fermentation workshops with odor-collection pipes on roofs to centralize odor treatment. Design ventilation systems to balance oxygen supply for microbes while avoiding excessive airflow that spreads odors.
- Adsorption and filtration: Use natural adsorbents like activated charcoal or zeolite to trap odors. Biofilters with microbes can also break down harmful gases into harmless CO₂ and water.
In short, these natural methods can effectively reduce odors from organic fertilizer production lines without relying on chemicals.
