[0019] Workflow: Before use, install the device in a suitable location and connect it to the power supply. Connect the pump 3's suction port to the sewage tank via a flexible connecting pipe, and connect the right side port of the mixing shell 21 to the next-stage sewage tank via a flexible connecting pipe. The device is equipped with an external controller, which is electrically connected to the vacuum ultraviolet radiation lamp 13, drive motor 22, water pump 3, and air pump 5. Manual operation of the external controller can adjust the operating status of the vacuum ultraviolet radiation lamp 13, drive motor 22, water pump 3, and air pump 5. All of the above are existing technologies. When using the device, the operator first uses the external controller to activate the vacuum ultraviolet radiation lamp 13, drive motor 22, water pump 3, and air pump 5. Pump 3 and air pump 5 are started. Pump 3 transports water from the wastewater tank to the spiral reaction tube 14. Vacuum ultraviolet radiation lamp 13 irradiates the catalyst packing 15, causing a photocatalytic reaction that generates active oxygen species. The reflective coating 12 reflects the light from the vacuum ultraviolet radiation lamp 13 onto the inner wall of the reaction shell 11. The vacuum ultraviolet radiation lamp 13 irradiates the wastewater flowing through the spiral reaction tube 14, thus performing vacuum ultraviolet oxidation on the wastewater. Simultaneously, the active oxygen species generated by the catalyst packing 15 decompose pollutants in the wastewater. After flowing through the spiral reaction tube 14, the wastewater enters the bottom of the mixing shell 21 through the water supply pipe 4. At the same time, the... Air pump 5 delivers air into reaction shell 11. Vacuum ultraviolet radiation lamp 13 irradiates the air, causing oxygen to generate ozone. The air carrying ozone enters the gas delivery pipe 25 through gas pipe 6, then flows into the distribution box 26 fixed by fixing block 28. The ozone is dispersed and discharged through the gas outlet 27 located on the lower side of the distribution box 26. Drive motor 22 drives rotating shaft 23, which in turn drives multiple pairs of stirring plates 24 to rotate, causing the wastewater in mixing shell 21 to form a swirling flow. This ensures thorough mixing of wastewater and ozone, oxidizing the wastewater. Air, due to density differences, can be discharged from the upper rear end of mixing shell 21. The treated wastewater is then discharged through the mixing... The wastewater is discharged into the next-stage wastewater tank through the right-side pipe of the shell 21. This device can irradiate the catalyst packing 15 with vacuum ultraviolet radiation lamp 13, and the active oxygen species generated by the catalyst packing 15 purify the wastewater. At the same time, the wastewater is purified by irradiating it with vacuum ultraviolet radiation lamp 13, and ozone is generated by irradiating the air with vacuum ultraviolet radiation lamp 13. The ozone is dispersed and discharged from the lower side of the mixing shell 21 through the diversion box 26 and the air outlet 27. The wastewater in the mixing shell 21 is stirred by the rotating shaft 23 and the stirring plate 24 to make the ozone and wastewater fully mixed. This device can fully synergize photocatalysis, vacuum ultraviolet light and ozone oxidation to effectively improve the wastewater treatment effect.
