Offensive gases are collected from the odor-control structures and transported together with the main odor conduit to the upper section of the bio-washing stage. The atomizing nozzles fully atomize the water, which then mixes with the air flow, quickly reaching a saturated humidity state in the gas to be treated. Part of the odor molecules in the gas are absorbed by the washing liquid, creating favorable conditions for the stable operation of the bio-filtration process.
After being treated in the biological washing section, the gas enters the biological filtration section from bottom to top. As the gas moves upwards, the odor molecules in the gas pass through the packing layer, making full contact with the biofilm formed on the surface of the packing. The microorganisms oxidize and decompose the odor molecules, converting them into carbon dioxide, water, minerals, etc., thereby achieving the purpose of odor purification.
The treated gas after passing through the biological filter unit is then discharged through a 15-meter exhaust pipe, meeting emission standards.
Process Principle and Features: The biological deodorization device is a widely researched, mature technology, and a commonly used method for treating malodorous gases in practice. Its processing flow involves the gas containing malodorous substances being pre-treated through dust removal, humidification, or cooling, and then passing through the filter bed from bottom to top. During this process, the malodorous substances transfer from the gas phase to the water-microorganism mixed phase (biological layer) within the filter layer, where they are decomposed by the metabolic action of microorganisms attached to the filter material. This method primarily utilizes the biochemical action of microorganisms to decompose pollutants into harmless substances. Microorganisms use organic matter as the matrix required for their growth and reproduction, converting large or complex organic molecules through heterotrophic actions into simple inorganic substances like water and carbon dioxide, and simultaneously, through assimilatory actions and utilizing the energy produced during the heterotrophic process, promoting the growth and reproduction of the microorganisms, thus creating favorable conditions for further enhancing their ability to process organic matter. The essence of pollutant removal is the absorption, metabolism, and utilization of organic matter as nutrients by microorganisms. This process is a complex one, consisting of physical, chemical, physicochemical, and biochemical components. It can be simplified into the following expression:
Volatile organic compounds vary in composition, resulting in different decomposition products. Different types of microorganisms produce distinct metabolic byproducts. For nitrogen-free organic substances like carboxylic acids and formaldehyde, the final products are carbon dioxide and water. For sulfur-containing malodorous components, under aerobic conditions, they are oxidized and decomposed into sulfate ions and sulfur. For nitrogen-containing malodorous substances like amines, they release NH3 through ammonification, which can then be oxidized by nitrite bacteria into nitrite ions, and further oxidized by nitrate bacteria into nitrate ions.
