[0002] Modern society is facing an ever-increasing population and urbanization, and sewage treatment has become a crucial environmental protection and public health measure. Furthermore, anaerobic and aerobic integrated sewage treatment equipment can efficiently treat sewage, decomposing and removing organic matter and suspended solids to meet environmental protection requirements. In modern society, environmental protection and sustainable development are becoming increasingly important issues, and the performance of sewage treatment equipment is crucial for protecting water resources and reducing environmental pollution. Therefore, anaerobic and aerobic integrated sewage treatment equipment has emerged in the context of modern life, aiming to address the challenges of sewage treatment in the urbanization process and provide more economical, efficient, and environmentally friendly solutions.

[0003] Existing anaerobic and aerobic integrated sewage treatment equipment generally filters impurities in sewage directly through a filter screen during use. However, after a period of use, the filter screen needs to be disassembled and cleaned. Sewage treatment needs to be stopped during the cleaning process, which affects the overall sewage treatment efficiency. At the same time, during the aerobic treatment process of the existing anaerobic and aerobic integrated sewage treatment equipment, additional ventilation equipment is required to ensure that the inside of the aerobic treatment tank is always in a state of sufficient oxygen. However, this process requires additional operating steps, which affects the convenience of using the overall equipment. Utility Model Content

The cross-section of the second mounting block 22 is an L-shaped structure, and a filter screen 19 is fixedly connected to the inner wall of the anaerobic tank 2. A push-pull block 10 and a movable block 21 are respectively slidably connected through the side wall of the opposite side of the anaerobic tank 2. The push-pull block 10 is slidably connected to the upper surface of the filter screen 19, and impurities on the filter screen 19 are cleaned by the displacement of the push-pull block 10. A plurality of springs 23 are fixedly connected between the movable block 21 and the inner wall of the second mounting block 22, and the springs 23 are used to realize the reset of the movable block 21.

[0023] A connecting pipe 15 is fixedly connected to the bottom wall of the anaerobic tank 2, and the end of the connecting pipe 15 away from the anaerobic tank 2 is fixedly connected to the aerobic tank 3. An air inlet pipe 14 is fixedly connected to the top wall of the gas tank 4, and an air outlet pipe 13 is fixedly connected to the bottom wall of the gas tank 4, and the end of the air outlet pipe 13 away from the gas tank 4 is fixedly connected to the aerobic tank 3. A water outlet pipe 17 is fixedly connected to the bottom wall of the aerobic tank 3.

[0024] An anaerobic biological filler layer 18 is fixedly connected to the inner wall of the anaerobic tank 2, and the sewage is passed through the anaerobic biological filler layer 18 to achieve anaerobic treatment of the sewage. An aerobic biological filler layer 16 is fixedly connected to the inner wall of the aerobic tank 3, and the sewage after anaerobic treatment is passed through the aerobic biological filler layer 16 to achieve aerobic treatment of the sewage.

[0025] The side wall of the first mounting block 1 is rotatably connected to a rotating shaft 25 through a bearing, and the side wall of the first mounting block 1 is fixedly connected to a motor 9 through a bracket. The output end of the motor 9 is fixedly connected to the end of the rotating shaft 25 located outside the first mounting block 1, and the motor 9 serves as the only power drive system for the entire device.

[0026] One end of the rotating shaft 25 located inside the first mounting block 1 is fixedly connected to a turntable 5, a smooth rod 6 is fixedly connected to the side wall of the turntable 5, a sliding block 7 is slidably connected between the inner top wall and the inner bottom wall of the first mounting block 1, a sliding hole 8 is opened on the side wall of the sliding block 7, and the smooth rod 6 is slidably connected to the sliding block 7 through the sliding hole 8.

[0027] A push-pull rod 11 is slidably connected to the side wall of the gas tank 4. The end of the push-pull rod 11 located inside the gas tank 4 is fixedly connected to the extrusion plate 12. The end of the push-pull rod 11 located outside the gas tank 4 and the end of the push-pull block 10 located outside the anaerobic tank 2 are both fixedly connected to the sliding block 7, and the extrusion plate 12 is slidably connected to the inner wall of the gas tank 4.

[0028] A one-way valve is provided inside the air inlet pipe 14 and the air outlet pipe 13. The one-way valve inside the air inlet pipe 14 only allows gas to enter the gas tank 4 from the outside through the air inlet pipe 14, and the one-way valve inside the air outlet pipe 13 only allows gas to enter the aerobic tank 3 from the inside of the gas tank 4 through the air outlet pipe 13 to prevent gas backflow and affect the normal use of the equipment. A ventilation hole is provided on the top wall of the aerobic tank 3, and the sliding connection between the movable block 21 and the anaerobic tank 2, the sliding connection between the push-pull block 10 and the anaerobic tank 2, and the sliding connection between the extrusion plate 12 and the gas tank 4 are all glued with sealing pads to form a sealed environment to prevent sewage in the equipment from leaking.

[0029] In the present invention, first, the sewage to be treated is injected into the anaerobic tank 2 through the water injection pipe 24, and then the motor 9 is started, thereby driving the rotating shaft 25 fixedly connected to the output end of the motor 9 to rotate, and then driving the turntable 5 fixedly connected to the rotating shaft 25 to rotate, thereby driving the smooth rod 6 fixedly connected to the side wall of the turntable 5 to rotate around the rotating shaft 25, thereby driving the smooth rod 6 to penetrate the sliding block 7 slidably connected to perform reciprocating motion, and then driving the push-pull block 10 fixedly connected to the side wall of the sliding block 7 to perform reciprocating motion, thereby driving the push-pull block 10 to repeatedly scrape and clean the impurities on the surface of the filter 19. When the push-pull block 10 moves to the limit toward the second mounting block 22, the fixed block 20 fixedly connected to the side wall of the push-pull block 10 will push the movable block 21 open, thereby discharging the scraped impurities out of the equipment. When the push-pull block 10 moves to the limit toward the second mounting block 22, the fixed block 20 fixedly connected to the side wall of the push-pull block 10 will push the movable block 21 open, thereby discharging the scraped impurities out of the equipment. When the sliding block 7 moves in the direction away from the second mounting block 22, the movable block 21 is reset under the action of the spring 23, thereby reclosing the anaerobic tank 2. The impurities on the filter screen 19 are continuously cleaned in this reciprocating manner, thereby achieving the effect of reducing the cleaning frequency of the filter screen 19. At the same time, with the reciprocating motion of the sliding block 7, the push-pull rod 11 fixedly connected to the side wall of the sliding block 7 also reciprocates together, thereby driving the extrusion plate 12 fixedly connected to the push-pull rod 11 to reciprocate. When the extrusion plate 12 moves in the direction close to the sliding block 7, air is drawn into the gas tank 4 through the air inlet pipe 14. When the extrusion plate 12 moves in the direction away from the sliding block 7, the air inside the gas tank 4 is discharged into the aerobic tank 3 through the air outlet pipe 13, thereby achieving the effect of increasing oxygen inside the aerobic tank 3 while cleaning impurities.
