A variety of ozone oxidation treatment devices are disclosed in the prior art, such as an environmentally friendly ozone catalytic oxidation sewage treatment equipment and treatment method proposed in the Chinese invention patent with publication number CN114890598B. The ozone treatment equipment pre-treats the wastewater with high temperature sterilization by a high temperature boiler, and then discharges it into the treatment tank for treatment. The steam generated by the high temperature boiler during the high temperature treatment drives the cam and the aeration pipe to rotate in the treatment tank, so that ozone diffuses in large quantities in the treatment tank, and drives the connecting frame to reciprocate up and down to clean the water holes of the catalyst bed, so that the ozone and the catalyst bed are fully in contact and fused, thereby improving the treatment effect and efficiency of the wastewater.
