The high-efficiency oxidation technology plays an important role in the field of treatment of refractory wastewater or advanced treatment of wastewater, and the currently commonly used high-efficiency oxidation technology mainly comprises Fenton oxidation, ozone oxidation and ultraviolet light catalytic oxidation, namely the ultraviolet light and ozone or ultraviolet light and hydrogen peroxide combined photocatalytic oxidation. The mechanism for degrading pollutants by the ultraviolet photocatalytic oxidation technology mainly comprises three aspects: (1) the ultraviolet light directly acts with pollutants; (2) the oxidant directly acts with the pollutant; (3) ultraviolet light excites the oxidant to generate hydroxyl free radicals with strong oxidation activity to react with pollutants. The latter is most important to be optimal in oxidation effect, but because the life cycle of hydroxyl free radicals in water is very short, if the ultraviolet catalytic oxidation is to be effectively realized, the ultraviolet light is required to be sufficiently irradiated into the treated wastewater, but many ultraviolet catalytic oxidation systems do not fully consider the factor, so that the oxidation effect is not ideal, energy consumption is wasted, meanwhile, for the application of the ultraviolet light in water treatment, the tube wall of the lamp tube needs to be polluted by the wastewater, the intensity of the light source is reduced, regular cleaning and maintenance are required, the current design is not considered, and the operation effect is unstable.
