Biological deodorization technology

Biological deodorization technologyUtilizing the physiological processes of microorganisms to convert harmful substances in organic waste gas into simple inorganic substances, such asCO2, H2O, and other simple inorganic substances. This is a harmless method for removing organic waste gas. In fact, biological purification methods utilize the life activities of microorganisms to convert harmful substances in exhaust gas into simple inorganic substances (such as carbon dioxide and water) and cellular substances. The main processes are biological washing, biological filtration, and biological drip filtration.

Gaseous pollutants with different compositions, concentrations, and gas volumes have their own effective biological washing systems. This biological scrubbing tower is suitable for the treatment of waste gases with low purification volume, high concentration, easy solubility, and low biological metabolic rate. For large volume and low concentration exhaust gases, a biological filter bed can be used. Biological drip filtration bed is more suitable for producing acidic substances.

Under normal conditions, complete biological treatment of organic waste gas includes three basic steps: organic pollutants in organic waste gas first come into contact with water and can quickly dissolve in water; The concentration of organic matter dissolved in the liquid film is low in the liquid. Under certain conditions, it can gradually diffuse into the biofilm and then be absorbed by microorganisms attached to the biofilm. The organic waste gas absorbed by microorganisms will be degraded in its own physiological metabolism process and ultimately transformed into a compound that does not harm the environment.

Odorous gases are collected through pipelines and enter the deodorization device of the biological filter. During the process of passing through the biological filling layer, the airflow and circulating fluid complete three processes: gas-liquid biological diffusion, liquid-solid diffusion, and biological oxidation. Microorganisms use gaseous odorous substances as nutrients, and odorous substances andVOCs are synthesized by microbial oxidation and generate energy during the conversion process, providing energy for the growth and reproduction of microorganisms. Microorganisms cause gaseous substances to emit a foul odor. Please continue to stop, and pure gas will be discharged through the induced draft fan.
