Biological deodorization system

Biological deodorization system

The purification and treatment of industrial organic waste gas (VOCS), garbage stations, and sewage deodorization is an important aspect of air pollution control. Currently, China mainly adopts purification measures for high concentration industrial organic waste gas (such as catalytic combustion method, absorption method, and adsorption method), but there is no economically effective treatment measure for low concentration industrial organic waste gas (pollutant concentration<5g/m3). Biological purification technology is aimed at solving this problem, which has no recycling value, Developed for the problem of low concentration organic industrial waste gas that disrupts people and pollutes the environment, it has been widely adopted in developed countries around the world.

All kinds of sewage treatment plants and industrial and mining enterprises will produce hydrogen sulfide, methane, methyl mercaptan, nitrogen and other volatile organic compounds (VOC) and other odorous gases in the acidic waste water tank, alkaline waste water tank, neutralization tank, primary sedimentation tank, aerobic tank, activated sludge return tank, etc. The waste gas will be collected by covering the Cesspit and then enter the biological filter pre washing unit through the pipeline. The waste gas in the pre washing section will be washed with alkali liquor. The waste gas treated in the pre washing section enters the biological treatment section of the biofilter, and the odor is absorbed and decomposed by microorganisms into small molecule compounds such as CO2 and H2O. The purified air treated by the biological filter is discharged at high altitude through a centrifugal fan in the exhaust function section.
