[0032] The driving unit drives the first air inlet pipe 7 and the branch pipe 8 to rotate, and the first air inlet pipe 7 drives the control shell 15 and the aeration plate 9 to rotate synchronously through the mounting frame 37, the slide plate 35 and the support plate 33, and the second compression spring 36 is in a compressed state, and the second compression spring 36 applies a thrust to the support plate 33 and the support frame 12, so that the support frame 12 is in close contact with the first protrusion 14, and the control shell 15 drives the end of the support frame 12 to slide on a plurality of first protrusions 14 in sequence, so that the support frame 12 drives the control shell 15 and the support plate 33 to reciprocate in the horizontal direction relative to the slide plate 35 and the first air inlet pipe 7, and the first The compression spring 26 is in a compressed state, and the first compression spring 26 applies pressure to the tooth plate 22 and the slider 27 so that the bottom end of the slider 27 is in close contact with the second protrusion 30.

[0034] Working principle: The urban recycled water to be treated enters the box 1 through the water inlet pipe 2, and the ozone is injected into the first air inlet pipe 7. The ozone then enters the aeration plate 9 through the branch pipe 8, the hose 11 and the second air inlet pipe 10. After passing through the aeration plate 9, the ozone enters the box 1 in the form of tiny bubbles and quickly contacts with the water flow entering the box 1. The driving unit drives the first air inlet pipe 7 and the branch pipe 8 to rotate, so that the aeration plate 9 revolves around the first air inlet pipe 7. At the same time, the position adjustment structure adjusts the position of the aeration plate 9 so that the aeration plate 9 is relatively close to the first air inlet pipe 7. The air pipe 7 moves, thereby adjusting the position of the aeration plate 9 in multiple directions. The water flow mixed with ozone microbubbles contacts the electrochemical reaction mechanism 5 during the rising process, and a redox reaction occurs, thereby synergizing with the ozone in the water to catalyze and promote the decomposition of ozone to produce more hydroxyl free radicals to degrade trace toxic and harmful organic pollutants in the reclaimed water. The treated water is discharged through the outlet pipe 3, and the gas is discharged through the exhaust pipe 4. The position of the aeration plate 9 is adjusted in multiple directions to make the microbubbles evenly distributed in the water, so that the reaction effect is better;

[0035] The driving unit drives the first air inlet pipe 7 and the branch pipe 8 to rotate, and the first air inlet pipe 7 drives the control housing 15 and the aeration plate 9 to rotate synchronously through the mounting frame 37, the slide plate 35 and the support plate 33, and the second compression spring 36 is in a compressed state, and the second compression spring 36 applies a thrust to the support plate 33 and the support frame 12, so that the support frame 12 is in close contact with the first protrusion 14, and the control housing 15 drives the end of the support frame 12 to slide on a plurality of first protrusions 14 in sequence, so that the support frame 12 drives the control housing 15 and the support plate 33 to reciprocate in the horizontal direction relative to the slide plate 35 and the first air inlet pipe 7, and the first compression spring 26 is in a compressed state. In the compressed state, the first compression spring 26 applies pressure to the tooth plate 22 and the slider 27 so that the bottom end of the slider 27 is in close contact with the second protrusion 30. When the control housing 15 reciprocates in the horizontal direction, the control housing 15 drives the tooth plate 22 and the slider 27 to move synchronously in the horizontal direction. The slider 27 slides reciprocatingly on a plurality of second protrusions 30 in sequence. The second protrusion 30 can push the slider 27 and the tooth plate 22 to reciprocate in the vertical direction. The tooth plate 22 drives the first gear 23 and the first rotating shaft 16 to rotate forward and reverse periodically. The first rotating shaft 16 and the second damping plate 21 drive the first damping plate 20 and the second rotating shaft 19 to rotate through friction. The second rotating shaft 19 The aeration plate 9 can be driven to rotate by the second air inlet pipe 10 to change the inclination angle of the aeration plate 9. When the aeration plate 9 and the second air inlet pipe 10 are inclined to a preset angle, the second air inlet pipe 10 and the corresponding stop strip 31 are in contact, so that the second air inlet pipe 10 and the aeration plate 9 stop inclining. The impact force generated by the instantaneous contact between the second air inlet pipe 10 and the stop strip 31 causes the aeration plate 9 to vibrate slightly, thereby preventing the micropores on the aeration plate 9 from being clogged and extending the service life of the aeration plate 9. As the first rotating shaft 16 and the second damping plate 21 continue to rotate, the second damping plate 21 cannot drive the first damping plate 20 and the second damping plate 21 to rotate by friction. The rotating shaft 19 rotates synchronously. When the first rotating shaft 16 rotates in the opposite direction, the second damping disc 21 can drive the first damping disc 20 and the second rotating shaft 19 to rotate in the opposite direction through friction, so that the aeration disc 9 and the second air inlet pipe 10 rotate in the opposite direction until the second air inlet pipe 10 contacts another stop bar 31, so that the aeration disc 9 can vibrate again. While the first air inlet pipe 7 rotates, the aeration disc 9 can be reciprocated relative to the first air inlet pipe 7, and the inclination angle of the aeration disc 9 can be changed, thereby solving the problems of nitrate nitrogen reduction and degradation of toxic and harmful pollutants, removal of macromolecular difficult-to-degrade organic matter, and uneven distribution of tiny bubbles;

[0036] The staff fixedly connects the external ozone intake pipe to the connector 42, drives the third gear 41 to rotate through the servo motor 40, and the third gear 41 drives the first intake pipe 7 to rotate relative to the connector 42 and the housing 1 through the second gear 38, so that the first intake pipe 7 drives the branch pipe 8 to rotate synchronously relative to the housing 1, and the branch pipe 8 drives the guide ring 39 to slide in the guide groove 45. Through the design of the guide ring 39, the fixing ring 44 and the guide groove 45, the branch pipe 8 can rotate smoothly relative to the housing 1, reducing the possibility of tilting and shaking of the branch pipe 8.
