摘　　要：挥发性有机物(VOCs)作为有毒有害物质,对空气质量造成了严重影响。其中活性炭吸附脱附及催化燃烧装置被广泛用于VOCs的控制排放,VOCs浓度较高时,存在无法稳定达标排放问题。通过对活性炭吸附脱附与催化燃烧原理及装置实际工况分析,对其进行了针对性的优化改造。改造后,非甲烷总烃平均排放浓度、平均排放速度分别达到7.61 mg/m^(3)和289.94 g/h,分别降低了76.70%和78.24%,完全满足VOCs排放标准。结果表明:通过优化改造,不仅提高了该装置对VOCs的处理效果,而且实现了VOCs稳定达标排放,达到了该区域空气质量控制的目的。Volatile organic compounds(VOCs)are recognized as toxic and hazardous substances that have a significant 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 alignment 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/m^(3) 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.
