Malodorous gases are collected from the odor-control required structures and transported together with the main odor conveyance pipeline to the upper section of the bio-washing stage. Atomizing nozzles fully atomize water, which then mixes with the air flow, quickly achieving a saturated humidity state in the gas to be treated. Some of the malodorous molecules in the gas are absorbed by the washing liquid, creating favorable conditions for the stable operation of the biological 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, fully contacting 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 goal of odor purification.
Gases processed through a biological filter are discharged through a 15-meter exhaust pipeline, 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 process involves the gas containing malodorous substances being pre-treated with 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) through 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 for their growth and reproduction, converting large molecules or complex organic substances into simple inorganic substances such as water and carbon dioxide through heterotrophic action and subsequent oxidation, while also using the energy produced during the heterotrophic action for assimilation, promoting the growth and reproduction of the microorganisms, and creating favorable conditions for further enhancing their ability to process organic substances. The essence of pollutant removal is the absorption, metabolism, and utilization of organic matter as nutrients by microorganisms. This process is a complex one composed of physical, chemical, physicochemical, and biochemical components. It can be simplified to the following expression:
Volatile organic compounds vary in composition, resulting in different decomposition products. Different types of microorganisms also yield distinct metabolic byproducts. For nitrogen-free organic substances such as carboxylic acids and formaldehyde, the final products are carbon dioxide and water. Sulfur-containing odorous components are oxidized and decomposed into sulfate ions and sulfur under aerobic conditions. Nitrogen-containing odorous substances like amines release NH3 through ammonification, which can then be oxidized by nitrite bacteria into nitrite ions and further oxidized by nitrifying bacteria into nitrate ions.
