Volatile organic compounds(VOCs)are recognized as toxic and hazardous substances that have a sig-nificant impact on air quality.Among the aforementioned methods,the activated carbon adsorption desorption and catalytic combustion device is widely employed for the control of volatile organic compounds(VOCs)emissions.However,in instances where the concentration of VOCs is elevated,the challenge arises in maintaining a stable a-lignment with the established emission standards.Accordingly,this paper examines the fundamental principles of activated carbon adsorption desorption and catalytic combustion,as well as the practical operational parameters of the device.It then proceeds to undertake a targeted optimization and transformation.Following the transformation,the average emission concentration of non-methane hydrocarbons and the average emission rate reached 7.61 mg/m3 and 289.94 g/h,respectively.This represented a reduction of 76.70%and 78.24%respectively,and the levels were fully compliant with the VOCs emission standards.The results demonstrate that the optimization not only enhances the device's efficacy in treating VOCs,but also facilitates the stable and standardized emission of VOCs,thereby achieving the objective of air quality control in the region.
