In organic fertilizer production lines, deodorization is crucial for protecting the production environment and surrounding ecosystems. The following are some effective deodorization methods:

1. Biological Deodorization: Biological deodorization utilizes the metabolic activity of microorganisms to decompose and transform organic components in odor, thereby achieving deodorization. This method is environmentally friendly and has low operating costs, making it a widely used technology.

2. Chemical Treatment: Chemical treatment converts harmful components in odor into harmless substances through chemical reactions. For example, strong oxidants or catalysts are used to oxidize and decompose hydrogen sulfide, ammonia, and other odorous gases into carbon dioxide and water. This method is highly efficient, but care must be taken to avoid the production of harmful byproducts.

3. Physical Adsorption: Physical adsorption uses adsorbent materials such as activated carbon and molecular sieves to absorb odor molecules, thereby purifying the air. This method is simple to operate, does not produce secondary pollution, and is suitable for the primary treatment stage of deodorization.

4. Optimizing Production Processes: Adjust the ventilation rate of the material to increase ventilation, avoid localized oxygen deficiency, and reduce odor generation. Adding adsorbent materials (such as sawdust and rice husks) during the fermentation process can absorb some odors. Ensuring that materials are sealed during transportation and storage reduces odor emissions.

The combined application of these methods can effectively reduce odors during the organic fertilizer equipment production process, improve production environment quality, and minimize impact on the surrounding environment.
