[0030] The sewage is poured into the purified water tank 1 through the water inlet 2, and the sewage is preliminarily filtered through the filter 13 to screen out the solid impurities in the sewage, and then filtered and purified through the PPF cotton filter plate 9, the activated carbon filter plate 10 and the sterilizing filter plate 11 in turn, thereby improving the sewage purification effect of the device;

[0031] A dust box 3 is fixed at one end of the purified water tank 1, and a servo motor 7 is fixed inside the dust box 3. The servo motor 7 is protected by the dust box 3. One end of the threaded rod 15 passes through the protection box 6 and is fixed with a transmission rod 8. One end of the transmission rod 8 passes through the purified water tank 1 and is fixed with a transmission wheel. The two transmission wheels are connected by a belt drive, and the output end of the servo motor 7 is fixed to one of the transmission wheels; the two transmission rods 8 are rotated synchronously by the belt drive;

[0032] Limit rods are evenly fixed at one end of the purified water tank 1, and the limit rods on the same side are slidably connected to the limit slide 12. The end of the limit slide 12 close to the purified water tank 1 is slidably connected to the PPF cotton filter plate 9, the activated carbon filter plate 10 and the sterilizing filter plate 11.

[0033] Embodiment 2

[0034] Reference Figure 5 A device for treating high-concentration sewage and wastewater, both sides of the purified water tank 1 are provided with a limiting mechanism for applying pressure to the limiting slide plate 12, the limiting mechanism includes a mounting block 17, both sides of the purified water tank 1 are fixed with mounting blocks 17, one end of the inside of the mounting block 17 is slidably connected with a rotating rod 19, the rotating rod 19 slides and rotates with the mounting block 17, the top and bottom ends of the outer side of the rotating rod 19 are fixed with springs 18, one end of the spring 18 is fixed to the mounting block 17, an L-shaped support block 20 is fixed to the outer side of the rotating rod 19, and one side of the inside of the L-shaped support block 20 is slidably connected with the limiting slide plate 12;

[0035] The L-shaped support block 20 is pulled to drive the rotating rod 19 to slide inside the mounting block 17, and the mounting block 17 limits the rotating rod 19. The elasticity of the spring 18 drives the rotating rod 19 and the L-shaped support block 20 to generate a pulling force on the limiting slide plate 12, thereby applying pressure to the PPF cotton filter plate 9, the activated carbon filter plate 10 and the sterilizing filter plate 11, so as to facilitate the replacement of the PPF cotton filter plate 9, the activated carbon filter plate 10 and the sterilizing filter plate 11, and ensure the sealing effect;

[0036] A water inlet 2 is provided at the top of the purified water tank 1, a water outlet 5 is provided at one side of the purified water tank 1, and a discharge port 14 is provided at one end of the purified water tank 1.

[0037] One end of the purified water tank 1 is slidably connected to a storage box 4, and a plurality of groups of soft bristles are evenly distributed and fixed on the bottom end of the brush plate 16. The plurality of groups of soft bristles facilitate cleaning of the filter screen 13 and improve the cleaning effect of the filter screen 13. The screened solid impurities are cleaned from the inner side of the discharge port 14 to the inside of the purified water tank 1 through the brush plate 16 for centralized storage.

[0038] The use process of the high-concentration sewage and wastewater treatment device provided by the utility model is as follows: when in use, the sewage is poured into the interior of the purified water tank 1 through the position of the water inlet 2, the sewage is preliminarily filtered through the filter screen 13, the solid impurities in the sewage are screened out, and the sewage is filtered and purified through the PPF cotton filter plate 9, the activated carbon filter plate 10 and the sterilization filter plate 11 in sequence, so that the purified water is connected to the external pipe along the water outlet 5 and discharged;

[0039] During the preliminary screening, since the filter 13 adsorbs too many impurities, resulting in poor screening effect, the filter 13 needs to be cleaned regularly to ensure the screening effect of the filter 13. The output end of the servo motor 7 drives one of the transmission wheels to rotate, so that one of the transmission wheels drives the other transmission wheel to rotate synchronously through the belt, and the transmission wheel drives the transmission rod 8 and the threaded rod 15 to rotate synchronously, so that the threaded rod 15 drives the brush plate 16 to reciprocate at the top of the filter 13, thereby improving the screening effect of the filter 13 and cleaning the screened solid impurities into the interior of the storage box 4;

[0040] When the device is used for a long time, the filtering effects of the PPF cotton filter plate 9, the activated carbon filter plate 10 and the sterilizing filter plate 11 will gradually decrease. Therefore, the PPF cotton filter plate 9, the activated carbon filter plate 10 and the sterilizing filter plate 11 need to be replaced regularly. At this time, the rotating L-shaped support block 20 is pulled to drive the rotating rod 19 to slide inside the mounting block 17, so that the rotating rod 19 drives the spring 18 to extend, and then the L-shaped support block 20 is disengaged to apply pressure to the limiting slide plate 12, and the limiting slide plate 12 is disengaged from the limiting rod, which is convenient for replacing the PPF cotton filter plate 9, the activated carbon filter plate 10 and the sterilizing filter plate 11, and effectively improving the purification effect of the device;

[0041] On the contrary, the limiting slide plate 12 and the limiting rod are slid to fit the PPF cotton filter plate 9, the activated carbon filter plate 10 and the sterilizing filter plate 11, and the rotating L-shaped support block 20 is pulled to engage with the limiting slide plate 12. The elastic force of the spring 18 generates a pulling force on the L-shaped support block 20 and the limiting slide plate 12, so that the L-shaped support block 20 applies pressure to the PPF cotton filter plate 9, the activated carbon filter plate 10 and the sterilizing filter plate 11, effectively improving the sealing type of the PPF cotton filter plate 9, the activated carbon filter plate 10 and the sterilizing filter plate 11 and the purified water tank 1.
