The above materials are easily corroded when treating high-salinity wastewater, resulting in a reduced life of the ozone catalytic oxidation reactor. Utility Model Content

[0035] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0041] A catalyst layer 21 is disposed inside the reactor body 2;

[0042] The catalyst layer 21 is located at the lower part of the water outlet 4;

[0043] A baffle assembly 5 is provided at the bottom of the reactor body 2;

[0044] The reactor body 2 is made of chlorinated polyvinyl chloride.

[0045] In this embodiment, the bottom of the guardrail 1 of the ozone catalytic oxidation reactor is fixedly connected to the top edge of the reactor body 2, and the reactor body 2 is provided with a water inlet 3 and a water outlet 4. A catalyst layer 21 is provided on the inner side of the side wall of the reactor body 2 and between the water inlet 3 and the water outlet 4, which can catalytically oxidize the liquid in the reactor body 2. Since the liquid flow rate entering the reactor body 2 from the water inlet 3 is too large, the catalyst on the catalyst layer 21 is washed away and flows out of the reactor body 2 from the water outlet 4. Therefore, a baffle assembly 5 is provided at the bottom of the reactor body 2 to reduce the liquid flow rate at the water inlet 3 and prevent the catalyst layer 21 from being damaged by water flow. The reactor body 2, the water inlet 3, the water outlet 4 and the baffle assembly 5 are all made of chlorinated polyvinyl chloride, which prevents the ozone catalytic oxidation reactor from being corroded when filtering high-salinity liquids.

[0046] The utility model can reduce the flow rate of the liquid inside the reactor body 2 by arranging a baffle assembly 5 at the bottom of the reactor body 2, thereby preventing the catalyst layer 21 inside the reactor body 2 from being damaged.

[0056] Preferably, the length of the baffle 51 is 3 times the diameter of the water inlet 3 , and the width is 2 times the diameter of the water inlet 3 , or the length of the baffle 51 is 3 times the diameter of the water inlet 3 , and the width is 3 times the diameter of the water inlet 3 .
