Catalytic oxidation reactor and complete set of equipment

A catalytic oxidation reactor for water purification, comprising:

• a container, a reagent storage and delivery assembly, and an ultraviolet lamp tube, wherein the ultraviolet lamp tube is disposed in the container, and an annular gap cavity is defined between an inner wall of the container and an outer wall of the ultraviolet lamp tube;
• wherein a main body of the reagent storage and delivery assembly is stored with at least one oxidant, an outlet of the reagent storage and delivery assembly is disposed in the annular gap cavity, and the reagent storage and delivery assembly is configured to deliver the at least one oxidant to the annular gap cavity;
• and a sidewall of the container defines holes, and the holes are configured to make liquid to flow unidirectionally from an inside of the annular gap cavity to an outside of the container;
• and wherein the ultraviolet lamp tube and the container are disposed coaxially;
• wherein the reagent storage and delivery assembly comprises multiple reagent dispensers, the multiple reagent dispensers are disposed on the container at intervals along an axial direction, and an outlet of each of the multiple reagent dispensers is disposed in the annular gap cavity;
• wherein each of the multiple reagent dispensers comprises an annular main body, the annular main body is disposed in the annular gap cavity, the annular main body is provided with multiple outlets thereon, and the multiple outlets are arranged at intervals along a circumferential direction of the annular main body;
• and
• wherein an outer sidewall of the annular main body is connected to the multiple outlets through a threaded manner, and a top end of each of the multiple outlets is tightly adhered to the inner wall of the container.
