Advanced oxidation technology for H₂S odor gas using non-thermal plasma

Non-thermal plasma technology is a new type of odor treatment processing. We deal with H₂S from waste gas emission using non-thermal plasma generated by dielectric barrier discharge. On the basis of two criteria, removal efficiency and absolute removal amount, we deeply investigate the changes in electrical parameters and process parameters, and the reaction process of the influence of ozone on H₂S gas removal. The experimental results show that H₂S removal efficiency is proportional to the voltage, frequency, power, residence time and energy efficiency, while it is inversely proportional to the initial concentration of H₂S gas, and ozone concentration. This study lays the foundations of non-thermal plasma technology for further commercial application.
