Description

Technical Field

[0001] The utility model relates to the technical field of organic waste gas treatment, in particular to a biological purification tower for organic waste gas treatment. Background Art

[0002] With the development of industry and the progress of the times, manufacturers have increasingly improved the management of their own industrial workshops and factories. Among them, the treatment of waste gas generated in industrial production has received more and more attention from various manufacturers. The existing waste gas treatment methods mainly include activated carbon adsorption method, material absorption method, energy cutting oxygen method, combustion method and biological method. The most commonly used biological method is biological filtration method. The existing biological filtration method first contacts the waste gas with water to dissolve the pollutants in the waste gas in the water. The pollutants dissolved in the water enter the biological filter tank, and the microorganisms in the biological filter tank capture and absorb them, and then convert the pollutants into biomass and metabolic by-products, such as carbon dioxide and water, so that the waste gas is finally purified.

[0003] The following problems are prone to occur when using biological purification towers. First, the microorganisms in the purification tower capture and absorb pollutants, but as time goes by, the microorganisms will age, which will reduce the metabolism rate of the microorganisms, resulting in the inability to treat pollutants in time, so that the discharged gas still contains waste gas and thus pollutes the environment. Second, as time goes by, some of the pollutants in the biological filter will precipitate and aggregate together, resulting in different concentrations in the filter, making it impossible for the microorganisms to effectively capture and absorb the pollutants, thereby reducing the purification efficiency of the biological purification tower. Therefore, in response to the above problems, we have proposed a biological purification tower for organic waste gas treatment. Summary of the invention
