How to Effectively Remove the Odor in the Composting Process of Organic Fertilizer Production?

The generation of odor can be suppressed to some extent by adjusting the aeration of materials, increasing the ventilation and adding adsorbent materials. However, due to the large amount of fermentation materials, the concentration of odor generation and the relatively closed site, the odor concentration in the fermentation site is extremely high, and sometimes the ammonia concentration in the site is as high as 300mg/L or more. This also causes a large loss of nutrients. Measures need to be taken to collect and treat.

At present, there are many ways to eliminate odor, such as water washing, chemical treatment, combustion, adsorption, air dilution, masking, ozone oxidation, plasma, and biological deodorization method.　　Production of a more widely used is the biological deodorization method, this method is under the action of biological, biological and chemical reactions to decomposition, transformation of odor components to achieve the purpose of deodorization. Currently, the application is the use of microorganisms to deal with odor. Therefore, also called microbial deodorization method. The greater advantage of this method is the low operating costs, energy and resource saving and easy maintenance.
