The outer side of the oxidation reaction tank 6 is provided with two groups of through holes from top to bottom, and the two groups of through holes of the oxidation reaction tank 6 are respectively welded and connected with the water inlet pipe 8 and the water outlet pipe 7, and the upper side of the supporting filter plate 17 is placed with a catalyst layer 19; the outer side of the inner tank 18 is provided with two groups of through holes from top to bottom, and the two groups of through holes of the inner tank 18 are respectively welded and connected. The holes are sealed and bonded with an inlet pipe 8 and an outlet pipe 7 respectively; the water distribution device 22 comprises a water spray sleeve 2201, a rotating shell 2202, a rotating rod 2203, a fixed shell 2204 and a paddle 2205; the rotating shell 2202 is rotatably connected to the upper side of the fixed shell 2204, the water inlet at the bottom end of the fixed shell 2204 is provided with an inlet pipe 8, the rotating shell 2202 is welded to the top end of the rotating rod 2203, the bottom end of the rotating rod 2203 is welded to the paddle 2205; the water spray sleeve 2201 is sealed and screwed to the outer side of the rotating shell 2202.

[0049] When the utility model is performing sewage purification, the external sewage pipe is docked and installed on the water inlet pipe 8, and the sewage flows from the water inlet pipe 8 into the fixed shell 2204 through the through hole on the lower side of the fixed shell 2204, and then flows into the rotating shell 2202 through the through hole on the upper side of the fixed shell 2204. The sewage forms a water flow between the two sets of through holes opposite to each other in the fixed shell 2204 to impact the paddle 2205, and the paddle 2205 drives the rotating shell 2202 welded to the top of the rotating rod 2203. 2 rotates, the rotating shell 2202 drives the six groups of water spray sleeves 2201 screwed on the outer side to rotate synchronously, and the sewage flows into the inner tank 18 evenly from the through holes on the outer side of the water spray sleeves 2201.

At this time, the water spray sleeves 2201 stir the sewage and the ozone gas to fully merge and contact. As the sewage continues to flow into the inner tank 18, the sewage liquid level rises The sewage containing ozone passes through the supporting filter plate 17 and enters the catalyst layer 19 for ozone catalysis, so that ozone produces free radicals. When the sewage level rises to the upper side of the catalyst layer 19, the ultraviolet power controller 5 controls the UV ultraviolet lamp 3 to emit high-energy ultraviolet rays into the inner tank 18, and the stirring motor 1 drives the cleaning frame 15 welded to the outer side of the rotating shaft 16 to rotate.

When the sewage rises to the outlet pipe 7, the purified sewage flows out of the oxidation reaction tank 6 from the outlet pipe 7, and the ozone tail gas is discharged from the oxidation reaction tank 6 from the exhaust pipe 4, completing the oxidation water purification work.

[0050] In the disclosed embodiment, there are six groups of water spray sleeves 2201, which are distributed in a circular array around the central axis of the rotating shell 2202. The outer side surface of each group of water spray sleeves 2201 is densely covered with a large number of through-hole structures to facilitate the sewage to flow evenly into the bottom of the inner tank 18 in all directions, so that the sewage can be evenly contacted with the ozone sprayed by the micron aeration disk 20.

[0051] In the disclosed embodiment, the inner tank 18 is a sleeve structure that passes through from top to bottom. The inner tank 18 is made of transparent quartz. Through the good ultraviolet transmittance of quartz, the polluted water body is sealed and isolated from the UV lamp tube 3, so that the high-energy ultraviolet light beam of the UV lamp tube 3 can effectively pass through the inner tank 18 to sterilize the sewage and accelerate the catalytic reaction of ozone.

[0052] In the disclosed embodiment, the cleaning rack 15 is a frame structure that runs through the front and back. Five groups of stirring rods 14 are welded and connected to the inner side of the frame structure of the cleaning rack 15. The stirring rods 14 are arranged equidistantly from top to bottom.

A sponge pad is provided on the right side of the cleaning rack 15, and the sponge pad is attached to the inner side of the inner tank 18. During the rotation process, the cleaning rack 15 drives the sponge pad to wipe the inner wall of the inner tank 18 to prevent dirty substances from accumulating inside the inner tank 18 and reducing the light transmittance of the inner tank 18.

[0053] In the disclosed embodiment, the shovel frame 23 is an L-shaped folded plate structure, and the front side of the shovel frame 23 is densely covered with filter mesh holes.

[0055] In the disclosed embodiment, the lower side and the upper side of the fixed shell 2204 are provided with through holes, the rotating shell 2202 is rotatably connected to the through hole on the upper side of the fixed shell 2204, the water inlet pipe 8 is inserted into the through hole on the lower side of the fixed shell 2204, and the two groups of through holes of the fixed shell 2204 are opposite to the paddle 2205 up and down. The sewage flow flows into the through hole on the lower side of the fixed shell 2204 and impacts the paddle 2205, causing the paddle 2205 to rotate. The paddle 2205 drives the six groups of water spray sleeves 2201 screwed on the outer side of the rotating shell 2202 to rotate, and the water spray sleeves 2201 stir the sewage and ozone, so that the ozone is fully and evenly integrated into the polluted water body.
