Biotrickling Filter Tower for Odor Control

When the toxic, harmful and foul-smelling waste gas containing gas, liquid and solid mixture is introduced into the system through the collection pipeline, the biofilm formed by cultivating high-efficiency microbial strains growing on the biological filler is used to purify and degrade the pollutants in the waste gas. On the one hand, this biofilm uses the pollutants in the exhaust gas as nutrients for growth and reproduction; on the other hand, it decomposes the toxic and harmful odorous substances in the exhaust gas into simple inorganic substances such as non-toxic and harmless CO2, H2O, H2SO4, HNO3, etc. , so as to achieve the purpose of deodorization. The biotrickling filter tower uses microorganisms to deodorize, and converts odorous substances through the physiological metabolism of microorganisms, so that the target pollutants are effectively decomposed and removed, so as to achieve the purpose of odor control. Odors pass through a filter layer that is moist, porous and full of active microorganisms. Using the adsorption, absorption and degradation functions of microbial cells to odorous substances, the microorganisms have the characteristics of small cells, large surface area, and various types of adsorption metabolism, and decompose the odorous substances into simple inorganic substances such as CO₂, H₂O, H₂SO₄, HNO₃ after adsorption. The biological filter method has high deodorization efficiency and is suitable for waste gas treatment with low atmospheric concentration.
