Organic fertilizer production is an effective means of waste resource utilization, which can reduce the pollution of waste to the environment and is an environmental protection project. However, the management of some organic fertilizer production lines is not standardized. Many manufacturers produce in the open air or build simple greenhouses, which will inevitably cause secondary pollution to the environment in the organic fertilizer production line
, which violates the principle of environmental protection. Today, let's talk about the corresponding treatment method of odor generated by organic fertilizer production line?
Most of the raw materials of organic fertilizer are wastes and perishable substances, which are easy to produce ammonia, hydrogen sulfide and other harmful gases during the storage and fermentation of organic fertilizer raw materials.
Odor elimination and inhibition in organic fertilizer production line: the occurrence of odor can be inhibited to a certain extent by adjusting the ventilation of materials, increasing the ventilation capacity and increasing the adsorption materials. However, due to the concentration of odor, the large quantity of fermentation materials and the relative closure of the fermentation site, the odor concentration in the fermentation site is extremely high, and sometimes the ammonia concentration in the site is more than 300mg / L. This also causes a lot of nutrient loss. Measures need to be taken to collect and deal with.
At present, there are many ways to eliminate odor and waste gas in organic fertilizer production line, such as water washing, combustion, adsorption, air dilution, masking, ozonation, plasma and biological deodorization. Biological deodorization is the most widely used method in the production of organic fertilizer manufacturers. This method uses the activities of microorganisms to decompose and transform the odor to achieve the purpose of deodorization. The organic fertilizer machine
of this method is simple and easy to operate. It is suggested that the organic fertilizer manufacturers should build closed raw material warehouse, fermentation workshop and secondary aging workshop when conditions permit, so as to reduce the leakage of odor and harmful gas in the transformation process.
