The modular, combined rural household sewage treatment device provided by this application is suitable for the decentralized, small-volume water treatment needs in rural areas, and improves the treatment rate and effect of rural sewage by treating different water qualities separately. However, this patent also has the problem that sludge easily accumulates and clogs, affecting filtration and treatment efficiency. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a modular, modular rural household sewage treatment device, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: a modular rural household sewage treatment equipment, including a treatment tank, wherein a settling mechanism is provided at the front end of the internal part of the treatment tank; The settling mechanism includes a base plate, which is fixedly connected to the inner wall of the bottom of the treatment tank. A channel partition, a filter partition, and a separator are fixedly connected to the upper surface of the base plate. A filter baffle is fixedly connected to the front side of the channel partition. A flow groove is fixedly connected to the top of the side wall of the channel partition. A flip plate is rotatably connected to the bottom of the filter baffle. An arc-shaped plate is fixedly connected to the bottom front side of the channel partition. A guide groove is fixedly connected between the channel partition and the filter baffle. A trough block is fixedly connected to the bottom surface of the flip plate. A connecting rod is slidably connected to the side of the trough block. Two guide rods are fixedly connected to the front side of the filter baffle. A scraper is slidably connected to the outer side of the guide rod. Multiple filter grids are fixedly connected to the top surface of the filter baffle. An air jet pipe is fixedly connected to the side of the arc-shaped plate.

[0006] A drain outlet is fixedly connected to the rear side of the treatment box, a water inlet is fixedly connected to the front side of the treatment box, two sewage outlets are fixedly connected to the side of the treatment box, a filtration mechanism is provided behind the sedimentation mechanism, a disinfection mechanism is provided behind the filtration mechanism, a top box is fixedly connected to the top surface of the treatment box, and an air pump structure is provided inside the top box.

[0007] A filter screen is installed on the front side of the inner wall of the flow channel. A torsion spring is installed at the pivot of the tilting plate, and the two ends of the torsion spring are fixedly connected to the tilting plate and the filter baffle, respectively. When domestic sewage enters the treatment tank through the inlet, the heavier sediments in the sewage will settle to the bottom plate under gravity and enter the area below the bottom plate through the filter channel opened in the bottom plate. As the water level on the side of the filter baffle rises, the floating objects in the sewage are blocked on the side of the filter screen. The inlet is positioned to correspond with the filter screen, so that the sewage on the side of the filter baffle just covers the top and flows through the gaps between the filter screens into the space between the filter baffle and the channel partition. The sludge contained in the sewage between the filter baffle and the channel partition will further settle as it slowly flows through the flow channel. Tiny particles settle on the tilting plate, while sludge adheres to it in a fluid state. As the sludge accumulates, the gravity above the tilting plate increases, causing it to deflect around the connection point of the filter baffle under the weight of the sludge. During this deflection, the torsion spring undergoes torsional deformation. Once the tilting plate flips, the sludge is no longer blocked by the curved plate and slides down the tilting plate. Meanwhile, the sludge passing through the flow channel is blocked by the inner filter screen. As the tilting plate flips downward, it moves the connected trough blocks together. The movement of the trough blocks causes the connecting rod to pull the scraper, which scrapes away the floating debris blocked by the side of the filter screen along the guide rod. During periodic sludge discharge through the external valve at the drain outlet, the floating debris, sludge, and other sediments are carried out by the liquid flow below the base plate.

[0008] According to the above technical solution, the air pump structure includes an air pump body and an exhaust pipe. The input end of the air pump body is fixedly connected to the exhaust pipe, and the output end of the air pump body is fixedly connected to an air supply pipe. A side branch pipe is fixedly connected to the side wall of the air supply pipe, and a branch pipe is fixedly connected to the side of the exhaust pipe. A straight pipe is fixedly connected to the end of the branch pipe away from the exhaust pipe.

[0009] According to the above technical solution, the end of the side branch pipe away from the gas transmission pipe is fixedly connected to the partition plate, and the end of the straight pipe away from the branch pipe is fixedly connected to the partition plate.

[0010] According to the above technical solution, the filtration mechanism includes multiple guide bars, which are fixed in pairs on both sides of the filter partition. Filter plates are slidably connected between the guide bars on both sides. Filter media cores are provided inside the filter plates. A washing rack is provided between every two filter plates. A vertical rod is fixedly connected to the bottom surface of the washing rack. A floating box is fixedly connected to the bottom end of the vertical rod. A one-way valve body and a connecting valve are fixedly connected to the front and rear sides of the floating box, respectively. An inner valve block is slidably connected inside the one-way valve body. A side passage groove is opened on the side of the inner valve block. An inner ring groove is opened on the inner wall of the one-way valve body. A side passage pipe is fixedly connected to the end of the connecting valve away from the floating box. A toothed rod is fixedly connected to the rear side of the floating box. A connecting tooth is engaged on the top side of the toothed rod. A connecting pipe is fixedly connected to the top surface of the floating box. A side plate is fixedly connected to the top of the connecting pipe. An arc-shaped groove is opened on the side of the connecting tooth.

[0011] According to the above technical solution, the connecting valve outputs unidirectionally from the inside of the floating box to the outside, and the one-way valve body outputs unidirectionally from the outside of the floating box to the inside. The one-way valve body and the connecting valve have the same structure. A return spring is provided on the side of the inner valve block, and the two ends of the return spring are fixedly connected to the inner wall of the inner valve block and the one-way valve body, respectively. The internal cross-sectional connecting structure of the inner valve block is T-shaped. The side passage is a flexible tube. The connecting teeth are rotatably connected to the partition plate. The side plate extends backward to form a rotating shaft, which is fixedly connected to the partition plate. The connecting teeth are rotatably connected to the rotating shaft. The filtered water in the flow channel enters the side of the filter media core. Water permeates through... The filter media core flows below the filter baffle and around the floating box. When the air pump body of the air pump structure is in operation, it draws air through the exhaust pipe and branch pipe, and delivers air through the air supply pipe and side branch pipe. When the water in the floating box is low, the floating box is in its initial floating state. At this time, the straight pipe connected to the baffle plate is connected to the arc-shaped groove on the side of the connecting tooth, while the connecting pipe connected to the side plate is connected to the straight pipe and branch pipe through the arc-shaped groove and is in the air intake state. When the connecting pipe draws air from the top of the floating box, the air pressure inside the floating box decreases and a negative pressure is generated. Under the action of negative pressure, the water outside the floating box pushes the inner valve block to slide, causing the inner valve block to... The side passage groove slides to the inner ring groove and pulls the return spring. At this time, water outside the floating tank enters the one-way valve body, passes through the inner side of the inner valve block, and flows out from the side passage groove to the inner ring groove. Then, it enters the floating tank through the inner ring groove and the inner port of the one-way valve body. As the liquid in the floating tank increases, the gravity inside the floating tank increases, the buoyancy decreases, and it slowly sinks. During the sinking movement of the floating tank, it drives the connected toothed rod to mesh with the connecting tooth. The downward movement of the toothed rod drives the connecting tooth to rotate. After the connecting tooth rotates, it connects the connecting pipe to the side branch pipe through the arc groove. At this time, the gas delivered in the gas pipe is delivered to the arc groove through the connected side branch pipe. The arc groove connects to the side passage groove through the side passage groove. The plate enters the connecting pipe, and gas is supplied to the floating box through the connecting pipe. The gas in the floating box pressurizes the internal liquid surface, causing the liquid surface to flow unidirectionally from the inside of the floating box through the side pipe behind the partition plate after being pressurized. As the liquid in the floating box decreases, the buoyancy of the floating box increases, which starts to drive the toothed rod to mesh with the connecting tooth, and drives the connecting tooth to rotate. The rotating connecting tooth adjusts the arc groove to reconnect with the straight pipe. During the up and down movement of the floating box, the connected vertical rod slides through the filter partition, driving the washing rack to move up and contact the side of the filter media core. The washing rack cleans the adhering objects by contacting the side of the filter media core with the fixed brush, ensuring the filtration efficiency of the filter media core.

[0012] According to the above technical solution, the disinfection mechanism includes a material placement trough, which is fixedly connected to the rear side of the partition plate. Multiple filter screens are fixedly connected to the inner bottom surface of the material placement trough. A main gas tank is fixedly connected to the bottom end of the gas supply pipe. Secondary branch pipes are fixedly connected to both sides of the main gas tank. A rotating shaft sleeve is rotatably connected to the top end of the secondary branch pipe. A swing frame tube is fixedly connected to the outer wall of the rotating shaft sleeve. A short pipe is fixedly connected to the outer surface of the swing frame tube. An inner spiral blade is fixedly connected to the inner wall of the rotating shaft sleeve. A top cap is fixedly connected to the top end of the rotating shaft sleeve.

[0013] According to the above technical solution, the material trough is fixedly connected to the inner wall of the treatment tank, and the swing frame tube is rotatably connected to the filter screen. Gas is continuously supplied to the main gas tank through the gas supply pipe. The gas in the main gas tank is connected to the inside of the rotating shaft sleeve through the secondary branch pipe. As the gas passes through the rotating shaft sleeve and emerges upward from the small hole on the top cap, the gas will slowly deflect under the guidance of the inner spiral blade on the inner side of the rotating shaft sleeve. The deflection of the rotating shaft sleeve will drive the connected swing frame tube to deflect. At the same time, the gas in the rotating shaft sleeve will be sprayed out from the short pipe through the swing frame tube to aerate the surrounding water. Porous fillers such as polyethylene and polyurethane are added to the aeration tank. These fillers provide a huge attachment and growth surface for microorganisms, allowing microorganisms to prey on the protozoa of pathogenic bacteria in the water. At the same time, aeration increases the contact between oxygen and microorganisms, promoting aerobic microorganisms to consume inorganic matter in the water, thus playing a role in disinfection and auxiliary disinfection.

[0014] This invention provides a modular, modular household wastewater treatment system for rural areas. It offers the following advantages: This invention, by setting up a sedimentation mechanism, achieves the sedimentation of heavy objects through the filter tank of the base plate, while the filter baffle and filter screen intercept floating objects. When sewage flows through the flow channel, sludge settles on the tilting plate. The accumulated sludge causes the tilting plate to deflect and drive the linkage mechanism to automatically scrape off the floating objects on the filter screen, while the deposited sludge slides off. Finally, all pollutants are discharged periodically through the drain outlet, achieving efficient and continuous solid-liquid separation and automatic cleaning, effectively preventing blockage. This invention, through the installation of a filtration mechanism and the linkage between the air pump structure and the floating box, achieves automatic circulation and drainage. When the floating box rises, it draws water from the outside through internal negative pressure; when it sinks, it discharges water through pressurization. Simultaneously, the meshing of the toothed rod and the connecting teeth automatically switches the air intake and air delivery paths to control this process, allowing the floating box to act as a water pump to draw and deliver filtered water, improving filtration efficiency. At the same time, the up-and-down movement of the floating box drives the washing frame to clean the filter media core, thereby achieving self-cleaning of the filter media while completing water circulation and effectively maintaining filtration efficiency. In addition, when the connecting pipe delivers air, the air jet pipe connected to the connecting pipe sprays gas from the side of the arc plate. When the flip plate flips, the flip plate no longer blocks the nozzle of the air jet pipe, and the gas sprayed from the air jet pipe blows the sludge on the flip plate, assisting the flip plate in blowing off the attached sludge, while also promoting the downward flipping of the flip plate. This invention incorporates a disinfection mechanism that significantly expands the aeration contact area through rotating jets, promoting uniform water mixing. Combined with porous fillers such as polyethylene and polyurethane, it provides a large attachment surface for microorganisms, enabling them to effectively prey on pathogens. Simultaneously, the enhanced oxygen contact promotes the decomposition of inorganic matter in the water by aerobic microorganisms, thereby strengthening biological purification and auxiliary disinfection effects while efficiently increasing oxygen levels.

Detailed Implementation

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0018] Please see Figure 1-10 An embodiment of the present invention is: a modular rural household sewage treatment equipment, including a treatment tank 1, wherein a settling mechanism 5 is provided at the front end of the internal part of the treatment tank 1; The settling mechanism 5 includes a base plate 51, which is fixedly connected to the inner wall of the bottom of the treatment box 1. A channel partition 52, a filter partition 53, and a partition plate 54 are fixedly connected to the upper surface of the base plate 51. A filter baffle 56 is fixedly connected to the front side of the channel partition 52. A flow channel 55 is fixedly connected to the top of the side wall of the channel partition 52. A flip plate 57 is rotatably connected to the bottom of the filter baffle 56. An arc plate 58 is fixedly connected to the bottom of the front side of the channel partition 52. A guide channel 59 is fixedly connected between the channel partition 52 and the filter baffle 56. A trough block 510 is fixedly connected to the bottom surface of the flip plate 57. A connecting rod 511 is slidably connected to the side of the trough block 510. Two guide rods 513 are fixedly connected to the front side of the filter baffle 56. A scraper 514 is slidably connected to the outer side of the guide rods 513. Multiple filter grids 512 are fixedly connected to the top surface of the filter baffle 56. An air jet pipe 515 is fixedly connected to the side of the arc plate 58.

[0019] A drain outlet 2 is fixedly connected to the rear side of the treatment box 1, a water inlet 4 is fixedly connected to the front side of the treatment box 1, two sewage outlets 3 are fixedly connected to the side of the treatment box 1, a filter mechanism 6 is provided behind the sedimentation mechanism 5, a disinfection mechanism 7 is provided behind the filter mechanism 6, a top box 8 is fixedly connected to the top surface of the treatment box 1, and an air pump structure 9 is provided inside the top box 8.

[0020] A filter screen is installed on the front side of the inner wall of the flow channel 55. A torsion spring is installed at the pivot of the tilting plate 57, and the two ends of the torsion spring are fixedly connected to the tilting plate 57 and the filter baffle 56 respectively. When domestic sewage enters the treatment tank 1 through the inlet 4, the heavier sediments in the sewage will be deposited on the bottom plate 51 under the action of gravity, and enter the area below the bottom plate 51 through the filter channel opened in the bottom plate 51. As the water level on the side of the filter baffle 56 rises, the floating objects in the sewage are blocked on the side of the filter screen 512. The inlet 4 corresponds to the position of the filter screen 512. The wastewater on the side of the filter baffle 56 just covers the top and flows through the gaps between the filter grids 512 into the space between the filter baffle 56 and the channel partition 52. As the wastewater slowly flows through the flow channel 55, the sludge in the wastewater between the filter baffle 56 and the channel partition 52 further settles. The settled sludge and other small particles are deposited on the tilting plate 57. The sludge is in a fluid state and adheres to the tilting plate 57. As the sludge increases, the gravity above the tilting plate 57 increases, and the tilting plate 57 will rotate around the filter baffle 56 under the influence of the sludge's gravity. The deflection of the plate causes the torsion spring to deform. When the tilting plate 57 tilts, the sludge is no longer blocked by the arc plate 58 and slides down the tilting plate 57. The sludge passing through the flow channel 55 is blocked by the inner filter screen. As the tilting plate 57 tilts downward, it drives the connected trough block 510 to move together. The movement of the trough block 510 drives the connecting rod 511 to pull the scraper 514 to scrape the floating objects blocked by the side of the filter screen 512 downward along the guide rod 513. The sludge is then periodically discharged at the drain outlet 2 through an external valve. When sewage is flowing, floating debris, sludge, and other sediments are carried out by the liquid flow below the base plate 51. The sediments are settled in the filter tank of the base plate 51. The filter baffle 56 and filter screen 512 intercept floating debris. When sewage flows through the flow channel 55, sludge settles on the tilting plate 57. The accumulated sludge causes the tilting plate 57 to deflect and drive the linkage mechanism to automatically scrape off the floating debris on the filter screen 512. At the same time, the deposited sludge slides off. Finally, all pollutants are discharged periodically through the drain outlet 2, achieving efficient and continuous solid-liquid separation and automatic cleaning, effectively preventing blockage.

[0021] The air pump structure 9 includes an air pump body and an exhaust pipe 91. The input end of the air pump body is fixedly connected to the exhaust pipe 91. The output end of the air pump body is fixedly connected to an air supply pipe 94. A side branch pipe 95 is fixedly connected to the side wall of the air supply pipe 94. A branch pipe 92 is fixedly connected to the side of the exhaust pipe 91. A straight pipe 93 is fixedly connected to the end of the branch pipe 92 away from the exhaust pipe 91.

[0022] The end of the side branch pipe 95 away from the gas transmission pipe 94 is fixedly connected to the partition plate 54, and the end of the straight pipe 93 away from the branch pipe 92 is fixedly connected to the partition plate 54.

[0023] The filtration mechanism 6 includes multiple guide bars 61, which are fixed in pairs to the two sides of the filter baffle 53. Filter plates 62 are slidably connected between the guide bars 61. Filter media cores 63 are installed inside the filter plates 62. A washing rack 64 is installed between every two filter plates 62. A vertical rod 65 is fixedly connected to the bottom of the washing rack 64. A floating box 66 is fixedly connected to the bottom end of the vertical rod 65. A one-way valve body 67 and a connecting valve 68 are fixedly connected to the front and rear sides of the floating box 66, respectively. A sliding valve 68 is slidably connected inside the one-way valve body 67. The inner valve block 671 has a side passage groove 672 on its side. The inner wall of the one-way valve body 67 has an inner ring groove 673. The end of the connecting valve 68 away from the floating box 66 is fixedly connected to a side passage pipe 69. The rear side of the side of the floating box 66 is fixedly connected to a toothed rod 611. The top side of the toothed rod 611 is engaged with a connecting tooth 613. The top surface of the floating box 66 is fixedly connected to a connecting pipe 610. The top of the connecting pipe 610 is fixedly connected to a side plate 612. The side of the connecting tooth 613 has an arc-shaped groove 614.

[0024] The connecting valve 68 outputs one-way from inside the floating box 66 to outside, and the one-way valve body 67 outputs one-way from outside the floating box 66 to inside. The one-way valve body 67 and the connecting valve 68 have the same structure. A return spring is provided on the side of the inner valve block 671, and the two ends of the return spring are fixedly connected to the inner walls of the inner valve block 671 and the one-way valve body 67, respectively. The internal cross-sectional structure of the inner valve block 671 is T-shaped. The side pipe 69 is a flexible hose. The connecting tooth 613 is rotatably connected to the partition plate 54. The side plate 612 extends backward to form a rotating shaft, which is fixedly connected to the partition plate 54. The connecting tooth 613 is rotatably connected to the rotating shaft. The filtered water in the flow channel 55 enters the side of the filter media core 63. The water passes through the filter media core 63 and enters below the filter partition plate 53. The water flows to the vicinity of the floating box 66. When the air pump body of the air pump structure 9 is in working condition, the air pump body draws air through the exhaust pipe 91 and the branch pipe 92, and delivers air through the air supply pipe 94 and the side branch pipe 95. When there is little water in the floating box 66, the floating box 66 is in the initial floating state. At this time, the straight pipe 93 connected to the partition plate 54 is connected to the arc groove 614 on the side of the connecting tooth 613, while the connecting pipe 610 connected to the side plate 612 is in the air intake state through the arc groove 614 connected to the straight pipe 93 and the branch pipe 92. When the connecting pipe 610 draws air from the top of the floating box 66, the air pressure inside the floating box 66 decreases and a negative pressure is generated. Under the action of the negative pressure, the water outside the floating box 66 pushes the inner valve block 671 to slide, causing the inner valve block 671 to slide. The side passage groove 672 slides to the inner ring groove 673 and pulls the return spring. At this time, water outside the floating box 66 enters the one-way valve body 67, passes through the inner valve block 671, and flows out from the side passage groove 672 to the inner ring groove 673. Then, it enters the floating box 66 through the inner ring groove 673 and the internal port of the one-way valve body 67. As the liquid in the floating box 66 increases, the gravity inside the floating box 66 increases, the buoyancy decreases, and it slowly sinks. During the sinking movement of the floating box 66, it drives the connected toothed rod 611 to mesh with the connecting tooth 613. The downward movement of the toothed rod 611 drives the connecting tooth 613 to rotate. After the connecting tooth 613 rotates, the connecting pipe 610 is connected to the side branch pipe 95 through the arc groove 614. At this time, the gas in the gas delivery pipe 94 is delivered through the connected side branch pipe 95. The gas is conveyed to the arc-shaped trough 614, which enters the connecting pipe 610 through the side plate 612 connected to the side. Gas is then supplied to the floating box 66 through the connecting pipe 610. The gas in the floating box 66 pressurizes the internal liquid surface, causing the liquid to flow unidirectionally from the inside of the floating box 66 through the side pipe 69 into the rear of the partition plate 54 via the connecting valve 68. As the liquid in the floating box 66 decreases, the buoyancy of the floating box 66 increases, causing the toothed rod 611 to mesh with the connecting tooth 613, and causing the connecting tooth 613 to rotate. The rotating connecting tooth 613 adjusts the arc-shaped trough 614 to reconnect with the straight pipe 93. During the up-and-down movement of the floating box 66, the connected vertical rod 65 slides through the filter partition 53, causing the washing frame 64 to move upwards and contact the side of the filter media core 63.The washing rack 64 uses fixed brushes to clean the sides of the filter media core 63, ensuring the filtration efficiency of the filter media core 63. This device achieves automatic circulating water extraction and drainage through the linkage between the air pump structure 9 and the floating box 66. When the floating box 66 floats, it draws water from the outside through internal negative pressure; when it sinks, it discharges water through pressurization. Simultaneously, the meshing of the toothed rod 611 and the connecting tooth 613 automatically switches between the air intake and air delivery pathways to control this process. The floating box 66 acts as a water pump, drawing and transporting the filtered water, improving filtration efficiency. The up-and-down movement of 66 drives the washing frame 64 to brush the filter media core 63, thus achieving self-cleaning of the filter media while completing water circulation, effectively maintaining filtration efficiency. Furthermore, when air is supplied through the connecting pipe 610, the jet pipe 515 connected to the connecting pipe 610 sprays gas from the side of the arc-shaped plate 58. When the flip plate 57 flips, it no longer obstructs the nozzle of the jet pipe 515, and the gas sprayed from the jet pipe 515 blows away the sludge on the flip plate 57, assisting the flip plate 57 in blowing off the attached sludge, and simultaneously promoting the downward flipping of the flip plate 57.

[0025] The disinfection mechanism 7 includes a material trough 71, which is fixedly connected to the rear side of the partition plate 54. Multiple filter screens 72 are fixedly connected to the inner bottom surface of the material trough 71. A main air tank 73 is fixedly connected to the bottom end of the air supply pipe 94. A secondary branch pipe 74 is fixedly connected to both sides of the main air tank 73. A rotating shaft sleeve 75 is rotatably connected to the top end of the secondary branch pipe 74.

An inner spiral blade 78 is fixedly connected to the inner wall of the rotating shaft sleeve 75. A top cap 79 is fixedly connected to the top end of the rotating shaft sleeve 75.

[0026] The material trough 71 is fixedly connected to the inner wall of the treatment box 1, and the swing frame tube 76 is rotatably connected to the filter screen cover 72. Gas is continuously supplied to the main gas tank 73 through the gas supply pipe 94. The gas in the main gas tank 73 is connected to the inside of the rotating shaft sleeve 75 through the secondary branch pipe 74. As the gas passes through the rotating shaft sleeve 75 and rises from the small hole on the top cap 79, it will slowly deflect under the guidance of the inner spiral blade 78 on the inner side of the rotating shaft sleeve 75. The deflection of the rotating shaft sleeve 75 drives the connected swing frame tube 76 to deflect. At the same time, the gas in the rotating shaft sleeve 75 is sprayed out from the short pipe 77 through the swing frame tube 76 to aerate the surrounding water and fill the porous filler such as polyethylene and polyurethane. When these materials are added to the aeration tank, they provide a large surface area for microorganisms to attach and grow, allowing them to prey on pathogens and protozoa in the water. At the same time, aeration increases the contact between oxygen and microorganisms, promoting aerobic microorganisms to consume inorganic matter in the water, thus aiding in disinfection. The rotating jet can significantly expand the aeration contact area and promote uniform mixing of the water. Combined with the porous materials such as polyethylene and polyurethane, which provide a large attachment surface for microorganisms, enabling them to effectively prey on pathogens, the enhanced oxygen contact promotes the decomposition of inorganic matter in the water by aerobic microorganisms. Thus, while efficiently increasing oxygen, it also enhances the effects of biological purification and auxiliary disinfection.

[0027] Working principle: When domestic sewage enters the treatment tank 1 through inlet 4, heavier sediments in the sewage will settle to the bottom plate 51 under gravity and enter below the bottom plate 51 through the filter grooves opened in the bottom plate 51. As the water level on the side of the filter baffle 56 rises, floating objects in the sewage are blocked on the side of the filter screen 512. The position of inlet 4 corresponds to the filter screen 512, so that the sewage on the side of the filter baffle 56 just covers the top and flows through the gaps between the filter screens 512 into the space between the filter baffle 56 and the channel partition 52. The sludge contained in the sewage between the filter baffle 56 and the channel partition 52 will further settle when it slowly flows through the flow channel 55. The settled sludge and other small particles are deposited on the tipping plate 57. The sludge is in a fluid state and adheres to the tipping plate. On the rotating plate 57, as the sludge increases, the gravity above the rotating plate 57 increases. Under the action of the sludge gravity, the rotating plate 57 will deflect around the connection of the filter baffle 56. During the deflection process, the torsion spring will be torsional and deformed. When the rotating plate 57 is rotated, the sludge is no longer blocked by the arc plate 58. The sludge will slide down the inclined rotating plate 57, and the sludge passing through the flow channel 55 will be blocked by the inner filter screen. When the rotating plate 57 is rotated downward, it will drive the connected trough block 510 to move together. The movement of the trough block 510 will drive the connecting rod 511 to pull the scraper 514 to scrape the floating objects blocked on the side of the filter screen 512 downward along the guide rod 513. When the drain outlet 2 is regularly discharged through the external valve, the floating objects, sludge and other sediments will be carried out with the liquid flow below the base plate 51. Water filtered in the flow channel 55 enters the side of the filter media core 63, passes through the filter media core 63, flows under the filter baffle 53, and flows to the vicinity of the floating box 66. When the air pump body of the air pump structure 9 is in working condition, the air pump body draws air through the exhaust pipe 91 and branch pipe 92, and delivers air through the air supply pipe 94 and side branch pipe 95. When there is little water in the floating box 66, the floating box 66 is in the initial floating state. At this time, the straight pipe 93 connected to the partition plate 54 is connected to the arc-shaped groove 614 on the side of the connecting tooth 613, while the connecting pipe 610 connected to the side plate 612 is connected to the straight pipe 93 and the connecting tooth 613 through the arc-shaped groove 614. When the branch pipe 92 is in the suction state, and the connecting pipe 610 draws air from the top of the floating box 66, the air pressure inside the floating box 66 decreases and a negative pressure is generated. Under the action of the negative pressure, the water outside the floating box 66 pushes the inner valve block 671 to slide, causing the side passage groove 672 on the side of the inner valve block 671 to slide to the inner ring groove 673 and pull the return spring. At this time, the water outside the floating box 66 enters the one-way valve body 67, passes through the inside of the inner valve block 671, and flows out from the side passage groove 672 to the inner ring groove 673. Then, it enters the floating box 66 through the inner ring groove 673 and the internal port of the one-way valve body 67. As the liquid in the floating box 66 increases, the weight inside the floating box 66... As the force increases, the buoyancy decreases, and the floating box 66 slowly sinks. During its sinking movement, the connected toothed rod 611 engages with the connecting tooth 613. The downward movement of the toothed rod 611 causes the connecting tooth 613 to rotate. After the connecting tooth 613 rotates, the connecting pipe 610 connects to the side branch pipe 95 through the arc-shaped groove 614. At this time, the gas delivered in the gas supply pipe 94 is delivered to the arc-shaped groove 614 through the connected side branch pipe 95. The arc-shaped groove 614 enters the connecting pipe 610 through the side plate 612 connected to the side, and delivers gas to the floating box 66 through the connecting pipe 610. The gas in the floating box 66 pressurizes the internal liquid surface, causing the liquid surface to flow through the connecting valve 68 after being pressurized. The liquid flows unidirectionally from inside the floating box 66 through the side pipe 69 to the rear of the partition plate 54. As the liquid in the floating box 66 decreases, the buoyancy of the floating box 66 increases, which in turn drives the toothed rod 611 to mesh with the connecting tooth 613 and rotates the connecting tooth 613. This causes the rotating connecting tooth 613 to adjust the arc groove 614 to reconnect with the straight pipe 93. During the up-and-down movement of the floating box 66, the connected vertical rod 65 slides through the filter partition plate 53, causing the washing rack 64 to move upward and contact the side of the filter media core 63. The washing rack 64 cleans the attached substances by contacting the side of the filter media core 63 with the fixed brush, thus ensuring the filtration efficiency of the filter media core 63. Gas is continuously supplied to the main gas tank 73 through the gas supply pipe 94. The gas in the main gas tank 73 is then transported to the rotating shaft sleeve 75 through the secondary branch pipe 74. As the gas passes through the rotating shaft sleeve 75 and emerges upward from the small hole on the top cap 79, it slowly deflects under the guidance of the inner spiral blade 78 on the inner side of the rotating shaft sleeve 75. This deflection of the rotating shaft sleeve 75 drives the connected swing frame pipe 76 to deflect as well. Simultaneously, the gas in the rotating shaft sleeve 75 is ejected from the short pipe 77 through the swing frame pipe 76, aerating the surrounding water. Porous fillers such as polyethylene and polyurethane are added to the aeration tank. These fillers provide a large surface area for microorganisms to attach and grow, allowing them to prey on pathogenic protozoa in the water. At the same time, aeration increases the contact between oxygen and microorganisms, promoting aerobic microorganisms to consume inorganic matter in the water, thus aiding in disinfection.
