[0017] (2) The setting of the sewage treatment facility, the form of nitrogen bubbles can help maintain the uniform distribution of titanium dioxide particles in the sewage, prevent them from settling in the water, and ensure a longer effective reaction time.

[0018] (3) The wastewater treatment facility is set up so that titanium dioxide is mixed with nitrogen in the form of water mist and introduced into the wastewater.

[0044] The bubble suspension mechanism 4 includes a bubble disc 52, an air pump 53, an air supply pipe 54, an electronic valve 55, and an air outlet 57.

[0045] In practical use, the input end of water pump 46 is connected to sewage. The sewage enters the rotating drum 47 through drive pipe 44. The output end of motor 41 rotates, driving bevel gear 42 to rotate. The rotation of bevel gear 42 drives bevel gear 43 to rotate, which in turn drives drive pipe 44 to rotate, thus rotating the rotating drum 47. After being filtered by filter screen 48, the sewage is thrown into filter chamber 56 through outlet hole 49 to remove large particles and other impurities.

The titanium dioxide suspension is atomized by dripping it onto the ultrasonic atomizing plate 29 within the atomizing basin 30 via the dripping pipe 27. Electronic valve 33 and pressure reducing valve 34 are opened, compressing nitrogen gas in the nitrogen storage tank 31.

The ultraviolet lamp 36 is then turned on. The titanium dioxide is introduced into the wastewater in the form of water mist and bubbles, significantly increasing its surface area and improving the efficiency of the photocatalytic reaction. The nitrogen gas, in the form of bubbles, helps maintain the uniform distribution of titanium dioxide particles, preventing them from settling in the water and ensuring a more even distribution. During a prolonged and effective reaction, titanium dioxide generates highly oxidizing hydroxyl radicals under ultraviolet light irradiation. These active substances can rapidly destroy the cell structure of pathogenic microorganisms, achieving efficient sterilization. Nitrogen, as an inert gas, does not participate in the reaction but can replace oxygen in the water, reducing oxygen adsorption on the surface of titanium dioxide and enhancing the activity of the photocatalyst. After the wastewater treatment is completed, the drain valve 11 is opened to discharge the wastewater from the stirring chamber 7. The function of the first air outlet 10 is to discharge excess gas from the stirring chamber 7, and the function of the second air outlet 57 is to discharge the gas from the filter chamber 56. The above is the overall workflow of this invention. This step can be repeated for the next use.

[0046] As can be seen from the above embodiments, the beneficial effects of the present invention are as follows:

[0047] In wastewater treatment systems, titanium dioxide is introduced into the wastewater in the form of a water mist mixed with nitrogen. This significantly increases the surface area of ​​the titanium dioxide particles, improving the efficiency of the photocatalytic reaction. The nitrogen bubbles help maintain the uniform distribution of titanium dioxide particles in the wastewater, preventing sedimentation and ensuring a longer effective reaction time. Furthermore, the mixing of titanium dioxide with nitrogen during the agitation process allows for more even exposure to ultraviolet light, enhancing the bactericidal effect of ultraviolet radiation. Under ultraviolet light, titanium dioxide generates highly oxidizing hydroxyl radicals, which rapidly destroy the cell structure of pathogenic microorganisms, achieving highly efficient sterilization. Nitrogen gas is also present. The stirring effect of bubbles in water enhances the mixing of wastewater and titanium dioxide, increases the contact area between the photocatalyst and pollutants, and promotes a complete reaction. The stirring rod, by agitating the bubbles, ensures uniform distribution of titanium dioxide particles, avoiding uneven reaction caused by excessively high local concentrations. Nitrogen, as an inert gas, does not participate in the reaction but can replace oxygen in the water, reducing oxygen adsorption on the titanium dioxide surface and enhancing the activity of the photocatalyst. The filter assembly removes large particles, leaves, impurities, etc., from the wastewater, preventing clogging and damage to subsequent treatment equipment. The bubble suspension mechanism introduces microbubbles into the wastewater, causing floating oil and fine suspended solids to adhere to the bubbles and float to the surface, facilitating the removal of fine suspended impurities.
