Malodorous gases are collected from the structures requiring deodorization and then transported together with the main odor conveying pipeline to the upper section of the biological washing stage. The atomizing nozzles thoroughly atomize water, which then mixes with the air flow, quickly reaching 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, 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 passes through a 15-meter exhaust pipe, exiting via a blower after being processed by a biological filtration unit, meeting emission standards.
Process Principle and Features: The bio-odour removal device is a widely researched, mature technology, and commonly used method for treating malodorous gases in practice. Its treatment process involves the malodorous gas containing substances being pre-processed with dust removal, humidification, or cooling, then passing through the filter bed from bottom to top. As it filters through, the malodorous substances transfer from the gas phase to the water-microbial mixture phase (bio-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 a matrix for their growth and reproduction, converting large molecules or complex organic substances through heterotrophic processes into simple inorganic substances like water and carbon dioxide, while utilizing the energy produced during the heterotrophic process for assimilation. This results in the growth and reproduction of microbial organisms, creating favorable conditions for their enhanced 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, comprising physical, chemical, physicochemical, and biochemical components, which can be simplified to the following expression:
Volatile organic compounds vary, leading to different degradation products. Different types of microorganisms also produce diverse metabolic by-products. For organic substances without nitrogen, such as carboxylic acids and formaldehyde, their final products are carbon dioxide and water. For sulfur-containing malodorous compounds, under aerobic conditions, they are oxidized and decomposed into sulfate ions and sulfur. For nitrogenous malodorous substances like amines, ammonia (NH3) is released through ammonification, which can then be oxidized by nitrite bacteria into nitrite ions and further oxidized by nitrifying bacteria into nitrate ions.
