Treatment Principle Of Catalysts For Volatile Organic Compound Waste Gas Treatment

Catalysts for treating volatile organic compound (VOC) waste gas are a biological treatment technology initially applied to the treatment of odorous gases in agricultural production, odorous gases from processing, composting fermentation, and waste gas treatment from biological sludge. With the increasing severity of VOC pollution from industrial production, this technology has gradually been applied to the field of industrial waste gas purification.

The basic principle of its purification is as follows: Organic waste gas or odorous gas flows through a processor equipped with a liquid absorbent. In the processor, due to the concentration gradient between the gas and liquid phases of the pollutants, the concentration difference causes them to transfer from the gas phase to the liquid phase, where they are adsorbed by microorganisms. Through the metabolism of these microorganisms, the organic matter is decomposed and transformed into biomass and inorganic substances.

The basic process flow of biological treatment technology, taking biological filtration as an example, involves waste gas undergoing dust removal, temperature and humidity regulation, and then entering the biological treatment unit. After treatment by microorganisms, the gas can meet emission standards.
