Catalytic oxidation device and oxidation method for sewage treatment

The invention discloses a catalytic oxidation device for sewage treatment, and relates to the field of sewage treatment.The catalytic oxidation device is provided with an anti-blocking wheel for cleaning the inner wall of an oxygen outlet pipe, it can be guaranteed that flocculent solids precipitated in sewage cannot block air holes in the surface of the oxygen outlet pipe during work, and the situation that ozone cannot be introduced into a reaction bin due to the fact that the air holes are blocked during work is prevented; a scraping plate is arranged to clean the bottom of a reaction bin during rotation, so that the situation that precipitated solids are deposited at the bottom and accumulated at the bottom to influence normal operation of the device is prevented, and meanwhile, the situation that the precipitated solids are excessive, the catalytic oxidation reaction effect is reduced, and the sewage treatment effect is influenced is prevented; by arranging the stirring mechanism, the sewage in the react
