Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1 - Figure 2 The utility model provides an embodiment: a rural domestic wastewater treatment system, including a wastewater treatment tank 1, a manure inlet tank 2 is arranged inside the wastewater treatment tank 1, a feed plate 3 is fixedly connected to the top of the manure inlet tank 2, an egg sinking sterilization tank 4 is arranged inside the wastewater treatment tank 1, a sealing baffle is arranged between the manure inlet tank 2 and the egg sinking sterilization tank 4, a through hole 10 is opened inside the sealing baffle, a discharge tank 5 is arranged inside the wastewater treatment tank 1, a grille well 6 is arranged inside the discharge tank 5, a water collection tank 7 is arranged inside the wastewater treatment tank 1, a comprehensive tank 8 is arranged inside the wastewater treatment tank 1, a mud storage bucket 9 is fixedly connected to the bottom of the comprehensive tank 8, and a support component is arranged at the bottom of the wastewater treatment tank 1;

[0031] Specifically, first, the sewage is introduced into the manure tank 2 through the feed plate 3. In the manure tank 2, the sewage is initially precipitated and separated, which reduces the burden for subsequent treatment. Then the sewage is transported to the egg-sinking sterilization tank 4 through the through hole 10. Professional sterilization equipment and technology are used here to thoroughly kill pathogenic microorganisms, viruses, etc. in the sewage, ensuring that harmful substances in the sewage are effectively controlled. After being treated in the egg-sinking sterilization tank 4, the sewage is further transported to the discharge tank 5. In the middle of the discharge tank 5, a grille well 6 is provided, which can intercept larger particles in the sewage, such as paper towels, plastics, etc., to prevent these impurities from entering the subsequent treatment. The sewage then enters the collecting tank 7, where it is further collected and integrated. At the same time, the collecting tank 7 is equipped with a sewage pump to adjust the flow of wastewater to ensure the stable operation of the treatment facilities, which not only improves the treatment efficiency but also helps to save energy and reduce operating costs. The sewage is then transported to the integrated tank 8. At the bottom of the integrated tank 8, a sludge hopper 9 is provided, which is a device for collecting the sludge generated during the treatment process. Regular cleaning and disposal can ensure that the sludge will not cause secondary pollution to the environment. Finally, the sewage is finally filtered after the soil infiltration link at the front end of the integrated tank 8.

[0032] Reference Figure 3 The support assembly includes a bracket 11, the upper surface of the bracket 11 is fixedly connected to the lower surface of the wastewater treatment tank 1, and the outer walls of the grille well 6 are fixedly connected with positioning columns 19, the outer wall of the positioning column 19 is slidably connected to the inside of the wastewater treatment tank 1, and the bottom of the wastewater treatment tank 1 is fixedly connected with a fixed plate 12, the middle of the fixed plate 12 is rotatably connected with a connecting rod 13, and one end of the connecting rod 13 is fixedly connected with a handle 14, the outer wall of the connecting rod 13 is fixedly connected with a gear 15, and the outer wall of the gear 15 is rotatably connected to the inside of the fixed plate 12, the inside of the fixed plate 12 is slidably connected with a tooth plate 2 17, and the inside of the wastewater treatment tank 1 is slidably connected with a tooth plate 1 16, and the tooth plate 16 and the tooth plate 2 17 are both meshed with the gear 15, the outer wall of the positioning column 19 is fitted with a splint 20, and the outer wall of the splint 20 is fixedly connected with a fixed block 18, and one end of the fixed block 18 is fixedly connected to the outer walls of the tooth plates 16 and the tooth plates 17

[0033] Specifically, when the handle 14 is first turned, the force is transmitted to the gears 15 at both ends through the connecting rod 13. When the gear 15 starts to rotate, the adjacent tooth plates 16 and 17 are driven to move through the meshing method, thereby realizing the transmission of force and the conversion of motion. The movement of tooth plates 16 and 17 further drives the movement of the fixed block 18. Finally, driven by the fixed block 18, the splint 20 slides on the outer wall of the positioning column 19, which is achieved through the matching relationship between the splint 20 and the positioning column 19. The positioning column 19 plays a role of positioning and supporting here, ensuring the stability and accuracy of the splint 20 during the sliding process, and the sliding of the splint 20 directly determines the fixation and release of the grille well 6, thereby realizing the convenient cleaning of the grille well 6.

[0034] Working principle: When rural domestic wastewater treatment is needed, the sewage is first sent to the interior of the manure inlet tank 2 through the feed plate 3, and the sewage is collected through the manure inlet tank 2, and then sent to the interior of the egg-sinking sterilization tank 4 through the through hole 10 for sterilization, and then sent to the interior of the discharge tank 5, and the larger particles in the sewage, such as paper towels, plastics, etc., are filtered through the grille well 6 in the middle of the discharge tank 5, and then sent to the interior of the collection tank 7 for collection of the sewage. At the same time, the sewage flow is adjusted by the sewage pump inside the collection tank 7 to meet the operation requirements of the treatment facilities, and then it will be sent to the interior of the comprehensive tank 8, and further collected through the mud hopper 9 at the bottom of the comprehensive tank 8. The sludge generated during the treatment process is finally filtered through the soil infiltration at the front end of the integrated pool 8, thereby achieving deep treatment and purification of the sewage. Then, by turning the handle 14, the gears 15 at both ends are driven to rotate through the connecting rod 13, and then the rotation of the gear 15 drives the tooth plates 16 and 17 on both sides to move, and then the movement of the tooth plates 16 and 17 drives the fixed blocks 18 on both sides to move, so that the clamping plate 20 is driven by the fixed block 18 to slide on the outer wall of the positioning column 19, thereby fixing and releasing the positioning column 19, and then fixing and releasing the grille well 6, achieving the effect of convenient cleaning.
