[0020] Step 2: Start the motor to drive the turntable to rotate. The turntable drives the second turntable through the transmission effect of the crawler belt.

[0023] Step 5: After the catalyst is unloaded, start the ultraviolet irradiation mechanism and provide power to the ultraviolet lamp through the distribution box, so that it emits ultraviolet rays to irradiate the sewage. The action of ultraviolet rays stimulates the oxidation ability of the catalyst, thereby decomposing organic matter, bacteria and other pollutants in the sewage, achieving the purpose of purifying water quality.

[0024] The beneficial effects of the present invention are:

[0025] The present invention realizes automation, high efficiency and uniformity of sewage treatment by providing a treatment pool, a catalyst feeding mechanism and an ultraviolet irradiation mechanism, greatly improving the effect and efficiency of sewage treatment. Through the coordinated work of the cleverly designed catalyst feeding mechanism and the stirring device, it not only ensures that the catalyst can be evenly dispersed in the sewage, but also promotes the full mixing of sewage and catalyst through the stirring action, creating favorable conditions for photocatalytic reaction. At the same time, the introduction of the ultraviolet irradiation mechanism further enhances the catalytic effect of the catalyst, effectively decomposes pollutants such as organic matter and bacteria in the sewage, and realizes deep purification of water quality. In addition, the entire sewage treatment system has a compact structure, is easy to operate and maintain, has high practical value and broad application prospects, and provides strong support for environmental protection and sustainable utilization of water resources.

[0041] When sewage treatment is required, the sewage is discharged into the inner wall of the water reservoir 14, and then the motor 16 is started. The output end of the motor 16 drives the turntable 17 to rotate, and the turntable 17 drives the second turntable 19 to rotate through the crawler 18. The second turntable 19 drives the rear columnar rotating rod 113 to rotate, and the rear columnar rotating rod 113 drives the front columnar rotating rod 113 to rotate through the third turntable 114 and the second crawler 115.

[0045] When it is necessary to irradiate the sewage with ultraviolet light, the distribution box 34 provides power to the ultraviolet lamp 36, and the ultraviolet lamp 36 emits ultraviolet light to irradiate the sewage, so that the catalyst in the sewage can stimulate strong oxidizing ability under the action of ultraviolet light, thereby decomposing organic matter, bacteria and other pollutants in the sewage, thereby achieving the purpose of purifying the water quality. At the same time, the design of the irradiation plate 33 enables the ultraviolet light to be evenly irradiated to every corner of the sewage, avoiding irradiation blind spots and improving the sterilization efficiency. In addition, the fixed connection between the irradiation plate support pole 31 and the irradiation plate support frame 32 ensures the stability and firmness of the irradiation plate 33, avoids shaking or tilting during use, and ensures the normal operation of the ultraviolet irradiation mechanism 3.

[0046] In addition, the present invention also relates to a photocatalytic sewage treatment system and method, comprising the following steps:

[0048] Step 2: Start the motor 16 to drive the turntable 17 to rotate. The turntable 17 drives the second turntable 19 through the transmission effect of the crawler 18. The rotation of the second turntable 19 passes through a series of transmission components, including the rear columnar rotating rod 113, the third turntable 114 and the second crawler 115, and finally moves the catalyst unloading mechanism 2 forward as a whole, and drives the stirring roller 1110 to rotate, thereby preliminarily stirring the sewage in the water reservoir 14, ensuring that the pollutants in the sewage are evenly distributed, and creating favorable conditions for the addition of the catalyst and subsequent photocatalytic treatment;

[0049] Step 3: When the catalyst unloading mechanism 2 moves, the dual-axis motor 2418 is started to drive the rotating block 2419 to rotate. The rotating block 2419 then drives the sliding block 24110 to slide back and forth in the elliptical chute vertical plate 2429. This reciprocating motion is transmitted to the unloading bin 242 through the connecting structure, causing it to vibrate back and forth. This vibration helps the catalyst in the unloading bin 242 to fall evenly and stably into the sewage, ensuring that the catalyst can be fully mixed with the sewage, thereby improving the efficiency and effect of photocatalysis.

[0050] Step 4: While the catalyst is evenly dispersed in the sewage, the continuous rotation of the stirring roller 1110 further promotes the mixing of the sewage and the catalyst, ensuring that the catalyst can fully exert its catalytic effect. In addition, the rotation of the stirring roller 1110 helps to break up suspended particles and bubbles in the sewage, thereby improving the sewage treatment effect;

[0051] Step 5: After the catalyst is unloaded, the ultraviolet irradiation mechanism 3 is started, and the distribution box 34 provides power to the ultraviolet lamp 36, so that it emits ultraviolet rays to irradiate the sewage. The action of ultraviolet rays stimulates the oxidation ability of the catalyst, thereby decomposing organic matter, bacteria and other pollutants in the sewage, thereby achieving the purpose of purifying the water quality.

[0052] The working principle of the present invention is as follows: when sewage treatment is required, the sewage is discharged into the inner wall of the water reservoir 14, and then the motor 16 is started. The output end of the motor 16 drives the turntable 17 to rotate, and the turntable 17 drives the second turntable 19 to rotate through the crawler 18. The second turntable 19 drives the rear columnar rotating rod 113 to rotate, and the rear columnar rotating rod 113 drives the front columnar rotating rod 113 to rotate through the third turntable 114 and the second crawler 115. When the two second crawlers 115 rotate, the top of the second crawler 115 drives the catalyst unloading mechanism 2 to move forward as a whole. When the catalyst unloading mechanism 2 moves forward as a whole When moving, the dual-axis motor 2418 is started, and the front and rear output ends of the dual-axis motor 2418 drive the rotating block 2419 to rotate, and the rotating block 2419 drives the sliding block 24110 to slide back and forth on the inner wall of the elliptical chute vertical plate 2429. The sliding block 24110 drives the sliding cross bar 2427 to slide back and forth on the inner wall of the rectangular chute block 2413. The sliding cross bar 2427 drives the lower bin 242 to shake back and forth, so that the catalyst in the lower bin 242 falls evenly into the sewage. At the same time, the two cylindrical rotating rods 113 are driven by the fourth turntable 116 and the third crawler 117. The two tension stabilizing turntables 111 are driven to rotate, and the third crawler 117 drives multiple stirring roller turntable connecting rods 118 to rotate, and multiple stirring roller turntable connecting rods 118 drive the stirring roller turntable 119 to rotate, and the stirring roller turntable 119 drives the stirring roller 1110 to stir the sewage. When the catalyst unloading mechanism 2 moves as a whole to the front side of the water reservoir 14, the motor 16 is started in reverse at this time, and the output end of the motor 16 is reversed to drive the turntable 17 to rotate in the opposite direction. The turntable 17 drives the second turntable 19 to rotate in the opposite direction through the crawler 18, and the second turntable 19 drives the rear columnar rotating rod 113 to rotate in the opposite direction. The cylindrical rotating rod 113 drives the front columnar rotating rod 113 to rotate in the opposite direction through the third turntable 114 and the second crawler 115. At this time, the two second crawlers 115 rotate in the opposite direction, and the top of the second crawler 115 drives the catalyst unloading mechanism 2 to move backward as a whole until the catalyst unloading mechanism 2 moves to the initial position as a whole. After the catalyst is dispersed in the sewage, the distribution box 34 provides power to the ultraviolet lamp 36. The ultraviolet lamp 36 emits ultraviolet rays to irradiate the sewage, so that the catalyst in the sewage is stimulated to have a strong oxidizing ability under the action of ultraviolet rays, thereby decomposing organic matter, bacteria and other pollutants in the sewage to achieve water purification.
