[0030] Reference Figure 1-Figure 3, the utility model provides an embodiment: a sewage treatment equipment for municipal water supply and drainage, including a filter box 1, the top of the filter box 1 is fixedly connected to a water collecting box 2, the top of the water collecting box 2 is fixedly connected to a water inlet pipe 3, the outer wall of the water collecting box 2 is fixedly connected to a bracket 4, the upper surface of the bracket 4 is fixedly connected to a motor 15, the driving end of the motor 15 is fixedly connected to a rotating rod 16, the outer wall of the rotating rod 16 is rotatably connected to the inside of the water collecting box 2, the inside of the water collecting box 2 is rotatably connected to a rotating rod 27, the outer wall of the rotating rod 16 is fixedly connected to a gear 18, the outer wall of the rotating rod 27 is fixedly connected to a gear 29, the outer walls of the gear 18 and the gear 29 are both arranged on the outer wall of the water collecting box 2, the gear 18 and the gear 29 are meshed, the outer walls of the rotating rod 16 and the rotating rod 27 are fixedly connected to a cutting knife 10, and a filter assembly is arranged inside the filter box 1;

[0031] Specifically, the sewage is guided to the water collecting tank 2 through the water inlet pipe 3. The water collecting tank 2 is a container for storing the initial inflow of sewage in preparation for subsequent treatment. After the water collecting tank 2 collects the sewage, the motor 5 connected to the bracket 4 is started. The start of the motor 5 is the beginning of the entire mechanical treatment process. The motor 5 drives the rotating rod 6 to rotate, and the gear 8 on the rotating rod 6 rotates accordingly, and drives the gear 2 9 meshing with it to rotate. Due to the configuration of the gears, the rotation of the gear 2 9 causes the rotating rod 2 7 to rotate in the opposite direction. The rotating rods 1 6 and 2 7 are respectively equipped with cutting knives 10. These cutting knives 10 crush large particles of impurities in the sewage, such as plastic fragments, paper, etc. during rotation. This step is to prevent these large particles of impurities from clogging or damaging the subsequent filter 11. The sewage after cutting treatment flows to the filter 11, and the filter 11 further removes fine impurities to ensure the water purification effect. The equipment can not only effectively crush large particles of impurities in the sewage, but also protect the filter 11, extend its service life, and improve the efficiency and effect of the entire sewage treatment system.

[0032] Reference Figure 1-Figure 3 The filter assembly includes a filter screen 11, the outer wall of the filter screen 11 is fixedly connected to the inside of the filter box 1, the upper surface of the filter screen 11 is slidably connected to a brush roller 15, the lower surface of the filter screen 11 is fixedly connected to a protective cover 12, the inside of the protective cover 12 is fixedly connected to a motor 2 13, the driving end of the motor 2 13 is fixedly connected to a rotating shaft 14, the top of the rotating shaft 14 is fixedly connected to the inside of the brush roller 15, the outer wall of the filter box 1 is fixedly connected to a delivery pump 16, the input end of the delivery pump 16 is fixedly connected to an extraction pipe 17, the outer wall of the extraction pipe 17 is fixedly connected to the inside of the filter box 1, and the output end of the delivery pump 16 is fixedly connected to a drain pipe 18;

[0033] Specifically, when enough impurities have accumulated on the surface of the filter 11 and need to be cleaned, first start the motor 2 13 located inside the protective cover 12. This motor is responsible for driving the entire cleaning mechanism. The motor 2 13 drives the rotating shaft 14 to rotate. The brush roller 15 installed on the rotating shaft 14 rotates with the rotating shaft 14 and brushes the surface of the filter 11. The brush roller 15 is designed to physically remove impurities attached to the surface of the filter 11, such as soil, sediment and other particles. After the impurities on the surface of the filter 11 are brushed off by the brush roller 15, the delivery pump 16 is started. The delivery pump 16 extracts these impurities through the extraction pipe 17, and then the impurities are discharged from the system through the drain pipe 18 to prevent these impurities from re-entering the treatment system or affecting the environment.

[0034] Reference Figure 4 A water pump 19 is fixedly connected to the lower end of the outer wall of the filter box 1, and a water pump 20 is fixedly connected to the input end of the water pump 19. The outer wall of the water pump 20 is fixedly connected to the inside of the filter box 1. A delivery pipe 21 is fixedly connected to the output end of the water pump 19. A storage box 22 is fixedly connected to the outer wall of the delivery pipe 21. The outer wall of the storage box 22 is fixedly connected to the lower end of the outer wall of the filter box 1. A bilaterally symmetrical activated carbon filter plate 23 is slidably connected to the inside of the storage box 22. A sealing plate 24 is fixedly connected to the upper surface of the activated carbon filter plate 23. A handle is fixedly connected to the top of the sealing plate 24. A drain pipe 25 is penetrated and connected to the lower end of the outer wall of the storage box 22. A valve 26 is arranged inside the drain pipe 25.

[0035] Specifically, the water pump 19 is started and the sewage that has been preliminarily filtered is extracted from the filter box 1 through the suction pipe 20. This step is to transfer the sewage from the primary treatment stage to a deeper level of treatment. The extracted sewage is discharged into the storage box 22 through the delivery pipe 21. The storage box 22 provides a temporary storage point for the next treatment process. Two activated carbon filter plates 23 are installed inside the storage box 22. Due to its highly porous nature, activated carbon can adsorb organic compounds and certain inorganic substances in sewage, thereby further improving water quality. This step is particularly effective in removing color, odor and trace harmful substances. The treated water is discharged by rotating the valve 26 connected to the drain pipe 25. This control method allows the speed and direction of the water flow to be adjusted to meet different discharge requirements. By pulling the handle to drive the sealing plate 24 to move upward, the activated carbon filter plate 23 can be easily removed from the storage box 22. This design makes the replacement or cleaning of the activated carbon filter plate 23 more convenient and efficient.

[0036] Working principle: when the device needs to be used, first connect the water inlet pipe 3 to the sewage pipe, and discharge the sewage into the water collecting tank 2 through the water inlet pipe 3, and start the motor 15 connected to the bracket 4 at the same time, the motor 15 drives the rotating rod 16 to rotate, the rotation of the rotating rod 16 drives the gear 18 to rotate, the rotation of the gear 18 drives the gear 29 to rotate, and the rotation of the gear 29 drives the rotating rod 27 to rotate in the opposite direction, and the rotating rod 16 and the rotating rod 27 respectively drive the cutting knife 10 to rotate, so as to crush the large particles of impurities in the sewage to prevent affecting the filtering effect of the subsequent filter 11. When it is necessary to clean the impurities attached to the surface of the filter 11, first start the motor 2 13 inside the protective cover 12 to drive the rotating shaft 14 to rotate, and the rotating shaft 14 drives the brush roller 15 to move on the filter 1 1 surface is constantly rotated to clean the impurities on the surface of the filter screen 11, and at the same time, the delivery pump 16 is started to extract the cleaned impurities through the extraction pipe 17, and then discharged through the drain pipe 18. When the filtered sewage needs to be treated again, the water pump 19 is started to extract the filtered sewage inside the filter box 1 through the suction pipe 20, and then discharged to the inside of the storage box 22 through the delivery pipe 21. The sewage is adsorbed and filtered by the two activated carbon filter plates 23 inside the storage box 22 to improve the effect of filtering the sewage. Then, the treated sewage is discharged by rotating the valve 26 connected to the drain pipe 25, and the handle is pulled to move the sealing plate 24 upward to move the activated carbon filter plate 23 out of the storage box 22, so as to facilitate the replacement or cleaning of the activated carbon filter plate 23.
