The raw materials of organic fertilizers are mostly waste and perishable substances. Raw materials will produce harmful gases such as ammonia during storage and fermentation. Some smells, even though they are not harmful to health, can still have a mental or emotional impact and impact on a person. In the production of organic fertilizers, the activities of microorganisms can be used to transform odors and achieve the purpose of deodorization. This method has small investment and is easy to operate. It is recommended that organic fertilizer equipment manufacturers make the silos, fermentation workshops, and secondary aging workshops closed if conditions permit, to reduce the leakage of odors and harmful gases during the conversion process.
Many raw materials for organic fertilizer production contain a lot of water, such as pig manure, cow manure, chicken manure and other raw materials. During the material accumulation and fermentation process, the waste liquid will flow out and enter the ground, polluting the ground water. Therefore, it is necessary to carry out cement hardening and anti-seepage treatment on the ground of the fermentation workshop.
Dust pollution is the primary pollution and requires careful treatment. There are many links in which dust pollution occurs.
(1) Unloading raw materials into warehouses and transporting them in different workshops (2) Throwing raw materials (3) Crushing materials (4) Drying and cooling fertilizer granules. Many organic fertilizer manufacturers will build a dust removal room in the production workshop, and use induced draft fans and dust collectors to deal with the dust problem. Although dust is a source of pollution, these dusts all come from organic fertilizers. After collection, add raw materials for fermentation and continue to produce organic fertilizer.
