[0024] The right end of the bend is located on the inner bottom surface of the sewage tank 2, and the bottom end of the side pipe 5 is located on the inner bottom surface of the sewage tank 2.

[0025] A purification tank 12 is provided on the upper end of the base plate 1. A one-way valve 13 is fixedly connected between the purification tank 12 and the sewage tank 2. A second connecting pipe 14 is fixedly connected between the purification tank 12 and the sewage tank 2. The one-way valve 13 can protect the sewage tank 2 and prevent excessive pressure inside the sewage tank 2.

[0026] A cylindrical tube 15 is fixedly connected to the upper end of the purification box 12. An air extraction mechanism 16 is provided at the upper end of the cylindrical tube 15. A water extraction pipe 17 is fixedly connected to the bottom surface of the inner wall of the purification box 12.

[0027] The air extraction mechanism 16 includes a second motor 161, a second transmission rod 162, a second turbine fan 163, a third turbine fan 164, and a water-throwing plate 165. The second motor 161 is fixedly connected to the upper end of the cylindrical tube 15 via a bracket. A gap is left between the bracket and the cylindrical tube 15 to allow normal gas flow. The second transmission rod 162 is fixedly connected to the output end of the second motor 161.

[0029] It should be noted that the first motor 41, the ozone generator 8, and the second motor 161 can all be purchased on the market or customized from the factory, and the wiring connection method and control method are mature technologies in this field and have been fully disclosed, so they will not be described again in this article.

[0030] In summary, the ozone oxidation device for deep wastewater treatment provided by this utility model, during operation, the ozone generated by the ozone generator 8 enters the wastewater tank 2 through the bend pipe. The ozone inside the wastewater tank 2 reacts with the wastewater. To ensure sufficient reaction with the wastewater, the ozone remains inside the wastewater tank 2 and the cylindrical barrel 3. The first motor 41 drives the first transmission rod 42 to rotate, which causes the stirring rod 44 to stir the wastewater. This increases the fluidity of the wastewater, thus facilitating the reaction between the ozone and the wastewater. When the first transmission rod 42 rotates, the first bevel gear 43 drives the second bevel gear 64 to rotate. The second bevel gear 64 drives the first vortex fan 65 to rotate through the rotating rod 61. The rotation of the first vortex fan 65 draws the ozone inside the cylindrical barrel 3 into the side pipe 5 and discharges it through the bottom of the side pipe 5. At this time, the ozone can react with the wastewater again, thereby increasing the contact time with the wastewater.

[0031] The second motor 161 drives the second transmission rod 162 to rotate, which causes the second turbine fan 163 to extract the gas inside the purification chamber 12. At this time, the reacted gas enters the purification chamber 12 through the second connecting pipe 14. After the gas is discharged from the bottom of the second connecting pipe 14, it is purified by the liquid inside the purification chamber 12. At the same time, the rotation of the second transmission rod 162 drives the third turbine fan 164 to rotate. At this time, the liquid inside the purification chamber 12 can be drawn into the water pumping pipe 17 from the bottom and flows out from the top of the water pumping pipe 17. When the liquid flows out, the water-splashing plate 165 will splash the liquid, so that the liquid comes into contact with the gas again. This can improve the purification effect of the liquid inside the purification chamber 12 on the gas.
