How To Deodorize In Organic Fertilizer Production
Sources of Odor in the Process of Organic Fertilizer Production
The odor in the manufacture of organic fertilizer mainly comes from the rot and deterioration of raw materials, the fermentation of organic fertilizer and the drying of organic fertilizer. There are many kinds of odorous substances in organic fertilizers manufacturing, and they come from a wide range of sources. Generally, there has a smell of ammonia, hydrogen sulfide, etc., which will cause varying degrees of toxicity to human respiration, digestion, cardiovascular, endocrine and nervous systems. There are also health hazards, as well as mental or emotional stimulation and influence on people.
Odor generation stage in composting process
The ordor is mainly produced in the initial stage of organic material fermentation. Due to the rapid degradation of easily decomposable organic substances, a large amount of oxygen is consumed, resulting in local hypoxia and the production of small molecular organic substances and hydrogen sulfide. At this time, ammonia volatilization is not easy to occur due to the low pH. After about 1-2 weeks, a large amount of ammonia volatilization will occur as the pH value of the compost increases. So it will generate smelly ordor. At this point, the compost has gradually completed the primary fermentation. Click here to learn more about organic fertilizer compost
Suppression and Elimination of Odor During Composting
The generation of odor can be suppressed to a certain extent by adjusting the air permeability of the material, increasing the ventilation rate and adding adsorption materials. Here, SX fertilzer machine for compost can help you a lot. However, due to the large amount of fermentation materials, the concentration of odor and the relative closure of the site, the concentration of odor in the fermentation site is extremely high, and sometimes the concentration of ammonia in the site is as high as 300 mg/L or more. This also results in a large loss of nutrients. Measures are required for collection and processing.
At present, there are many methods to eliminate odor, such as water washing, chemical treatment, combustion, adsorption, air dilution, masking, ozone oxidation, plasma and biological deodorization.
The more widely used method in production is the biological deodorization method. This method is to decompose and transform odor components through biochemical reactions under the action of organisms to achieve the purpose of deodorization. So you can make ogranic fertilizer in an enviromentally friendly way. At present, most applications are to use microorganisms to deal with odor. So it is also called microbial deodorization method. The advantages of this method are low operating cost, saving energy and resources, and easy maintenance.
