非甲烷总烃降解技术研究与新型化学氧化工艺的应用OA

Non-methane total hydrocarbons(NMHC)are an important component of volatile organic com-pounds(VOCs)and are one of the key precursors causing urban photochemical pollution and ozone over-limi-tation.Current mainstream treatment technologies include catalytic combustion,biological degradation,photo-catalytic oxidation,and plasma technology,each with its own advantages and limitations.This paper focuses on introducing a new oxidation process based on a composite chemical agent(HY-2028A/B).Through industri-al application experiments in the waste gas treatment system of chemical enterprises,the degradation effect of this process on NMHC under different dosages of the agent was investigated.The results show that under optimized conditions,this process can reduce the NMHC concentration from over the instrument range(>330 mg/m3)to 72 mg/m3,demonstrating advantages such as high efficiency,low consumption,no secondary pollu-tion,and strong shock resistance.This research provides a new technical path for the collaborative treatment of industrial NMHC and nitrogen oxides(NOx).
