摘要：
In recent years, the strong oxidation power of ozone (O3) and radicals generated by an advanced oxidation method has been expected to be useful in water treatment. In this study, an energy conservation advanced oxidation process by fusion of microbubbles and plasma, which can be driven by a household bath pump, was proposed and evaluated for its usefulness and practical feasibility. In the experiments, the effects of the supplied gas types, generated O3, and various radicals on the oxidative decomposition were evaluated by decolorization tests using indigo carmine solution as a sample. In addition, dissolved concentration measurements for hydrogen peroxide and O3, and spectroscopic measurements of plasma were obtained. The results showed that the oxide radical and O3generated by the gas-liquid interface discharge in the bubbles were the dominant influences in the decolorization test. © 2021 Begell House Inc..
