Malodorous gases are collected from the odor control structures and sent to the upper section of the bio-washing stage via the main odor transport pipeline. Atomizing nozzles fully atomize the water, mixing it with the airflow to quickly reach 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 biofiltering 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 odor molecules are then oxidized and decomposed by microorganisms, converting them into carbon dioxide, water, minerals, etc., thereby achieving the purpose of odor purification.
Gases treated by the biological filter are then exhausted through a 15-meter exhaust pipeline in compliance with 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. The treatment process involves the malodorous gas containing substances being pre-treated with dust removal, humidification, or cooling, and then passing through the filter bed from bottom to top. As it passes through the filter layer, the malodorous substances transfer from the gas phase to the water-microorganism mixed phase (biological layer), where they are decomposed by the metabolic activity 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 substrate for their growth and reproduction, converting large or complex organic molecules into simple inorganic substances like water and carbon dioxide through heterotrophic decomposition, and then oxidizing them. Simultaneously, through assimilative processes and utilizing the energy produced during the heterotrophic process, the microorganisms grow and reproduce, 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, leading to different decomposition products. Different types of microorganisms produce varying 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.
