Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of excrement treatment, and particularly relates to a centralized resource treatment device and technical process for urban excrement. BACKGROUND

[0002] Urban excrement is organic waste generated in urban life, commercial activities (such as catering and slaughtering) and public facility operation, mainly including feces in domestic sewage, cleaning materials of septic tanks and feces-containing sewage in kitchens, and the like, and has the characteristics of complex composition (containing organic matter, pathogenic microorganisms, heavy metals, detergents and the like), stable discharge amount and strong concentration. If not treated in a standard manner, it is easy to cause black and odorous water, soil pollution, pathogen transmission (such as norovirus and Escherichia coli) and stench nuisance, and is one of the core issues of urban ecological environment governance.

[0003] The treatment of urban excrement needs to combine the four-stage process of "pretreatment-main treatment-advanced treatment-resource utilization", and select appropriate technologies for different types of excrement. The core goal of pretreatment is to remove coarse impurities, dregs, sand and part of oil in excrement, to create conditions for subsequent biochemical treatment. The main treatment is the core link of "harmless" of urban excrement, mainly degrading high-concentration organic matter through biological treatment technology, and killing pathogenic microorganisms through disinfection technology. If the effluent after treatment needs to be reused (such as municipal miscellaneous use and industrial cooling) or discharged into sensitive water bodies (such as the surrounding of drinking water sources), the advanced treatment link needs to be added. Urban excrement is rich in organic matter, nitrogen, phosphorus and other nutrients, and through resource utilization, the treatment cost can be reduced, and economic value can be created.

[0004] Due to the complex composition of excrement (containing oil, hair, kitchen waste residue, silt and the like) and the long-term anaerobic environment in a closed environment, pipe network blockage becomes a common problem. Blockage not only causes excrement to overflow and pollute the environment, but also increases the maintenance cost of the pipe network and shortens the service life, and in severe cases, even causes public health incidents. On the other hand, excrement sedimentation and filtration as the "front key link" of the whole process of excrement treatment, through physical action to realize solid-liquid separation, not only "reduce the burden and improve the quality" for the subsequent treatment link, but also has significant value in the aspects of environment, economy, safety and the like.

[0005] Therefore, a centralized resource treatment device and technical process for urban excrement are needed. SUMMARY

[0006] This invention proposes a centralized resource-based treatment device for urban sewage, which solves the common problems in existing technologies due to the complex composition of sewage (containing grease, hair, kitchen waste, silt, etc.) and its long-term presence in a closed anaerobic environment, leading to pipe network blockage. Blockage not only causes sewage overflow and environmental pollution but also increases pipe network maintenance costs, shortens service life, and in severe cases, even triggers public health emergencies. On the other hand, sewage sedimentation and filtration, as a "key pre-treatment step" in the entire sewage treatment process, achieves solid-liquid separation through physical action, which not only "reduces the burden and improves the quality" of subsequent treatment stages but also generates significant value in multiple dimensions such as environment, economy, and safety.

[0010] Preferably, the anti-stress groove plate is connected end to end by a front connecting plate, the anti-stress groove plate is distributed in a hexagonal structure, the two ends of the anti-stress groove plate are provided with slots, the anti-stress inclined plate is limited by a side baffle, and the motor housing is connected to the anti-stress groove plate by a connecting column.

[0011] Preferably, the output end of the second motor is connected to a front push plate, the side of the front push plate is fixedly connected to a transmission column, the end of the transmission column is fixedly connected to a resistance ring, the side of the resistance ring is fixedly connected to a resistance block, and the side of the resistance block is provided with a detachable arc-shaped side shovel.

[0012] Preferably, the surface of the front push plate is provided with a hollowed-out groove, the anti-force side blocks are distributed in an equidistant structure on the side of the anti-force ring, and the arc-shaped side shovel is designed with an inclined structure.

[0013] Preferably, the output end of the first motor is connected to a transmission belt, the end of the transmission belt is connected to a transmission collar, the side of the transmission collar is fixedly connected to a transmission rod, the surface of the transmission rod is vertically provided with a detachable and installable anti-force frame, the end of the transmission rod is provided with a detachable and installable limiting collar, the surface of the limiting collar is fitted with a connecting frame, the top of the connecting frame is provided with a side locking block, the top of the side locking block is provided with a T-shaped locking block, and the end of the transmission rod is provided with a detachable and installable annular sluice.

[0014] Preferably, the resisting frame is distributed in an equilateral triangular structure, the limiting collar and the transmission rod are embedded in a rotating structure, the limiting collar and the connecting frame are embedded in a rotating structure, and the connecting frame adopts a hollow structure design.

[0015] Preferably, the side locking block is embedded in the groove at the bottom of the top cover, the T-shaped locking block and the limiting slide groove form an embedded sliding structure, and the annular funnel is supported and connected by a force-bearing frame.

[0016] This invention also provides a centralized resource-based treatment device and technology for urban sewage, the technology including the following steps: S1: First, sewage from various parts of the city is transported through pipelines, eventually collected in one place, and then transported to the septic tank through the inlet pipe; S2: Because the feces are viscous, they are easily adsorbed onto the inner wall of the pipe. Therefore, when they are transported in the same pipe, the adhesion phenomenon becomes more obvious. At this time, it is necessary to effectively clean the inner wall of the pipe. The cleaning operation can be carried out by the cooperation of the internal support mechanism and the cleaning mechanism. S3: Place the inner support mechanism inside the pipe, and connect the other end with a rope for easy control. Due to the different diameters of the pipes, the tension spring can be used to adjust the angle of the two sets of anti-force inclined plates, thereby adjusting the exact position of the rollers and ensuring that the rollers in all directions of the inner support mechanism can effectively fit against the inner wall of the pipe. Due to the high humidity inside the pipe, the design of the motor housing can effectively ensure that the second motor is not easily affected by moisture. S4: Driven by the second motor, the cleaning mechanism will rotate. The front push plate will rotate via the second motor. Using the connection structure of the transmission column, the resistance ring will rotate in tandem with the front push plate. At this time, the resistance side blocks and arc-shaped side shovels around the resistance ring can be driven. Through the inclined structure design of the arc-shaped side shovel, the stains adhering to the inner wall of the pipe can be removed. S5: After the manure is transported to the collection tank through the pipeline, it will inevitably contain solid residues or large particles, which will affect the fermentation process. Therefore, the manure transported to the collection tank needs to be preliminarily screened. At this time, a screening mechanism is required. After the manure enters the annular sieve through the pipeline, it will be screened. Small particles and liquids will flow into the receiving sedimentation tank through the holes on the surface of the annular sieve, while solid residues or large particles will be blocked and accumulated by the annular sieve. At the same time, in order to avoid too much manure concentrating in one place of the annular sieve and causing blockage, the first motor is required to drive the transmission belt to rotate, which in turn drives the transmission rod and the annular sieve to rotate together. The centrifugal force generated by the rotation can remove the manure adhering to the annular sieve, thereby improving the manure screening efficiency. S6: The annular filter cylinder is susceptible to corrosion with long-term use and needs to be replaced periodically. This can be done by removing the top cover and taking out the side clip from the groove at the bottom of the top cover. At the same time, the other end of the annular filter cylinder can be removed and replaced using the sliding structure of the T-shaped clip and the limiting slide groove. The filtered manure will fall into the receiving sedimentation tank for further sedimentation. The settled manure will be transported to the fermentation tank through a high-level pipe, where fermentation will be achieved by the influence of microorganisms and other environmental factors. Finally, it will flow into the storage tank through a low-level pipe.

[0017] This invention proposes a centralized resource-based treatment device for urban sewage. Compared with existing technologies, the advantages of this invention are: 10. This invention, by setting an internal support mechanism, can handle operations on pipes of different sizes. The internal support mechanism is placed inside the pipe, and the other end is connected by a rope for easy dragging and control. Due to the different diameters of the pipes, the tension spring can be used to adjust the angle of the two sets of anti-force inclined plates, thereby adjusting the precise position of the rollers and ensuring that the rollers in all directions of the internal support mechanism can effectively fit against the inner wall of the pipe. To avoid excessive rotation angle of the anti-force inclined plates, the side baffle can form a limiting effect with the anti-force groove plate. At the same time, due to the high humidity inside the pipe, the design of the motor housing can effectively ensure that the second motor is not easily affected by moisture. 11. This invention, by setting up a cleaning mechanism, can remove stains adhering to the inner wall of the pipe; by using the drive of the second motor, the front push plate will be rotated. Due to the connection structure of the transmission column, the resistance ring will rotate in tandem with the front push plate. At this time, the resistance side blocks and arc-shaped side scrapers around the resistance ring can be driven. Through the inclined structure design of the arc-shaped side scrapers, the stains adhering to the inner wall of the pipe can be removed. 12. This invention, by setting up a screening mechanism, can perform preliminary screening of fecal waste transported to the septic tank. After the fecal waste enters the annular sieve through the pipe, it will be screened. Small particles and liquids will flow into the receiving sedimentation tank through the holes on the surface of the annular sieve, while solid residues or large particles will be blocked and accumulated by the annular sieve. At the same time, in order to avoid excessive fecal waste accumulating in one place of the annular sieve and causing blockage, the first motor needs to operate to drive the transmission belt to rotate, and drive the transmission rod and the annular sieve to rotate together. The centrifugal force generated by the rotation can remove the fecal waste adhering to the annular sieve, thereby improving the screening efficiency of fecal waste. 13. The present invention, by setting a top cover, a T-shaped locking block and a limiting slide groove, allows the annular auger to be replaced periodically; by disassembling the top cover, the side locking block can be taken out from the groove opened at the bottom of the top cover, and at the same time, by using the sliding structure of the T-shaped locking block and the limiting slide groove, the other end of the annular auger can be removed for replacement.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-10 The present invention provides a technical solution: a centralized resource utilization device for urban sewage, including a base 1, a sewage collection tank 2 on the top of the base 1, a detachable feed pipe 3 on the side of the sewage collection tank 2, an internal support mechanism 4 passing through the inside of the feed pipe 3, and a detachable cleaning mechanism 5 at the end of the internal support mechanism 4. The top of the septic tank 2 is equipped with a first motor 6, and the top side of the septic tank 2 is connected to a top cover 7. The bottom of the top cover 7 is equipped with a detachable screening mechanism 8, and the bottom side of the septic tank 2 is equipped with a discharge port.

[0022] Furthermore, a receiving sedimentation tank 9 is provided on the left side of the septic tank 2. A first partition 10 is provided on the side of the receiving sedimentation tank 9, which is attached to the inner wall of the septic tank 2. A high-level pipe 11 passes through the upper middle part of the first partition 10. A fermentation tank 12 is provided on the side of the first partition 10. A second partition 13 is provided on the side of the fermentation tank 12, which is attached to the inner wall of the septic tank 2. A low-level pipe 14 passes through the lower middle part of the second partition 13. A storage tank 15 is provided on the side of the second partition 13. A detachable arc-shaped connecting block 16 is provided on the inner wall of the top of the septic tank 2. A limiting groove 17 is provided at the bottom of the arc-shaped connecting block 16.

[0023] Furthermore, the end of the inner support mechanism 4 is provided with a front connecting plate 401, and the side of the front connecting plate 401 is provided with a detachable anti-force groove plate 402. The surface of the anti-force groove plate 402 is provided with a limiting groove plate 403 perpendicularly. The side of the limiting groove plate 403 is rotatably connected to an anti-force inclined plate 404. The side of the anti-force inclined plate 404 is provided with a side baffle 405 perpendicularly. The end of the anti-force inclined plate 404 is provided with a detachable roller 406. A tension spring 407 is connected at the center of the two sets of anti-force inclined plates 404. The side of the anti-force groove plate 402 is provided with a motor housing 408, and the outer side of the motor housing 408 is provided with a connecting post 409. The motor housing 408 has a detachable second motor 410 installed inside. By setting the internal support mechanism 4, it can handle pipes of different sizes. The internal support mechanism 4 is placed inside the pipe, and the other end is connected by a rope for easy dragging and control. Since the pipe diameter is different, the tension spring 407 can be used to adjust the angle of the two sets of anti-force inclined plates 404, thereby adjusting the exact position of the rollers 406. This ensures that the rollers 406 in all directions of the internal support mechanism 4 can effectively fit against the inner wall of the pipe. Since the humidity inside the pipe is high, the design of the motor housing 408 can effectively ensure that the second motor 410 is not easily affected by moisture.

[0024] Furthermore, the anti-stress plate 402 is connected end to end by the front connecting plate 401. The anti-stress plate 402 has a hexagonal structure and slots at both ends. The anti-stress inclined plate 404 is limited by the side baffle 405. The motor housing 408 is connected to the anti-stress plate 402 by the connecting column 409. The hexagonal structure of the anti-stress plate 402 can achieve all-round fitting of the pipeline. At the same time, in order to avoid the anti-stress inclined plate 404 from rotating too much, the side baffle 405 can limit the anti-stress plate 402. The connecting column 409 can ensure the stability of the motor housing 408 and the second motor 410.

[0025] Furthermore, the output end of the second motor 410 is connected to a front push plate 501. The side of the front push plate 501 is fixedly connected to a transmission column 502. The end of the transmission column 502 is fixedly connected to a resistance ring 503. The side of the resistance ring 503 is fixedly connected to a resistance block 504. The side of the resistance block 504 is provided with a detachable arc-shaped side scraper 505. Through the design of the cleaning mechanism 5, the stains adhering to the inner wall of the pipe can be removed. The driving operation of the second motor 410 will drive the front push plate 501 to rotate. Due to the connection structure of the transmission column 502, the resistance ring 503 will rotate in tandem with the front push plate 501. At this time, the resistance block 504 and the arc-shaped side scraper 505 around the resistance ring 503 can be driven. Through the inclined structure design of the arc-shaped side scraper 505, the stains adhering to the inner wall of the pipe can be removed.

[0026] Furthermore, the surface of the front push plate 501 is provided with a hollowed-out groove, the resistance side blocks 504 are distributed equidistantly on the side of the resistance ring 503, and the arc-shaped side scraper 505 is designed with an inclined structure; the hollowed-out design of the front push plate 501 can effectively reduce the resistance caused by sewage in the pipe, while the equidistant distribution of the resistance side blocks 504 will form a certain gap, which can ensure the flow of sewage in the gap; the inclined arc-shaped side scraper 505 can efficiently remove the stains adhering to the inner wall of the pipe.

[0027] Furthermore, the output end of the first motor 6 is connected to a transmission belt 801, and the end of the transmission belt 801 is connected to a transmission collar 802. A transmission rod 803 is fixedly connected to the side of the transmission collar 802. A detachable and installable anti-force frame 804 is vertically provided on the surface of the transmission rod 803. A detachable and installable limiting collar 805 is provided at the end of the transmission rod 803. A connecting frame 806 is sleeved on the surface of the limiting collar 805. A side locking block 807 is provided on the top of the connecting frame 806. A T-shaped locking block 808 is provided on the top of the side locking block 807. A detachable and installable annular sieve cylinder 809 is provided at the end of the transmission rod 803. Using the screening mechanism 8, the conveyed material can be screened. The fecal sludge sent to the septic tank 2 undergoes preliminary screening. After entering the annular sluice cylinder 809 through the pipe, the fecal sludge is screened. Small particles and liquids flow into the receiving sedimentation tank 9 through the holes on the surface of the annular sluice cylinder 809, while solid residues or large particles are blocked and accumulated by the annular sluice cylinder 809. At the same time, in order to avoid excessive fecal sludge concentrating in one place of the annular sluice cylinder 809 and causing blockage, the first motor 6 is required to drive the transmission belt 801 to rotate, which in turn drives the transmission rod 803 and the annular sluice cylinder 809 to rotate together. The centrifugal force generated by the rotation can remove the fecal sludge adhering to the annular sluice cylinder 809, thereby improving the screening efficiency of the fecal sludge.

[0028] Furthermore, the support frame 804 is distributed in an equilateral triangular structure, the limiting collar 805 and the transmission rod 803 are embedded in a rotating structure, the limiting collar 805 and the connecting frame 806 are embedded in a rotating structure, and the connecting frame 806 adopts a hollow structure design; the support frame 804 with its equilateral triangular structure distribution can provide stable support for the annular filter cylinder 809; at the same time, in order to avoid the resistance caused by the manure to the connection between the transmission rod 803 and the limiting collar 805 during the manure removal process, the limiting collar 805, the transmission rod 803 and the connecting frame 806 simultaneously form a rotating structure, which can ensure the rotational speed of the annular filter cylinder 809 and improve the screening efficiency.

[0029] Furthermore, the side locking block 807 is embedded in the groove at the bottom of the top cover 7, the T-shaped locking block 808 and the limiting slide groove 17 are embedded and sliding, and the annular cistern 809 is supported and connected by the abutment frame 804. By disassembling the top cover 7, the side locking block 807 can be removed from the groove at the bottom of the top cover 7. At the same time, by using the sliding structure of the T-shaped locking block 808 and the limiting slide groove 17, the other end of the annular cistern 809 can be removed and replaced.

[0030] This invention also provides a centralized resource-based treatment device and technology for urban sewage, the technology including the following steps: S1: First, sewage from multiple locations in the city is transported through pipelines and eventually collected in one place, and then transported to the septic tank 2 through feed pipe 3. S2: Because the feces are viscous, they are easily adsorbed onto the inner wall of the pipe. Therefore, when they are transported in the same pipe, the adhesion phenomenon becomes more obvious. At this time, it is necessary to effectively clean the inner wall of the pipe. The cleaning operation can be carried out by the cooperation of the inner support mechanism 4 and the cleaning mechanism 5. S3: The inner support mechanism 4 is placed inside the pipe, and the other end is connected with a rope for easy control. Due to the different diameters of the pipes, the tension spring 407 can be used to adjust the angle of the two sets of anti-force inclined plates 404, thereby adjusting the exact position of the roller 406, ensuring that the rollers 406 in all directions of the inner support mechanism 4 can effectively fit against the inner wall of the pipe. Due to the high humidity inside the pipe, the design of the motor housing 408 can effectively ensure that the second motor 410 is not easily affected by moisture. S4: Driven by the second motor 410, the cleaning mechanism 5 will rotate. The front push plate 501 will rotate through the second motor 410. Utilizing the connection structure of the transmission column 502, the resistance ring 503 will rotate in tandem with the front push plate 501. At this time, the resistance side block 504 and the arc-shaped side shovel 505 around the resistance ring 503 can be driven. Through the inclined structure design of the arc-shaped side shovel 505, the stains adhering to the inner wall of the pipe can be removed. S5: After the manure is transported to the manure collection tank 2 through the pipeline, it will inevitably contain solid residues or large particles, which will have a certain impact on the fermentation process. Therefore, the manure transported to the manure collection tank 2 needs to be preliminarily screened. At this time, the screening mechanism 8 is used to cooperate in the operation. After the manure enters the annular sieve cylinder 809 through the pipeline, it will be screened. Small particles and liquids will flow into the receiving sedimentation tank 9 through the holes on the surface of the annular sieve cylinder 809, while solid residues or large particles will be blocked and accumulated by the annular sieve cylinder 809. At the same time, in order to avoid too much manure concentrating in one place of the annular sieve cylinder 809 and causing blockage, the first motor 6 needs to be operated to drive the transmission belt 801 to rotate, and drive the transmission rod 803 and the annular sieve cylinder 809 to rotate together. The centrifugal force generated by the rotation can remove the manure adhering to the annular sieve cylinder 809, thereby improving the manure screening efficiency. S6: The annular filter cylinder 809 is susceptible to corrosion due to long-term use and needs to be replaced regularly. This can be done by removing the top cover 7 and taking out the side clip 807 from the groove at the bottom of the top cover 7. At the same time, the other end of the annular filter cylinder 809 can be removed and replaced by using the sliding structure of the T-shaped clip 808 and the limiting slide groove 17. The filtered manure will fall into the receiving sedimentation tank 9 for further sedimentation. The sedimented manure will be transported to the fermentation tank 12 through the high-level pipe 11, where fermentation will be achieved by utilizing the influence of microorganisms and other environmental factors. Finally, it will flow into the storage tank 15 through the low-level pipe 14.

[0031] Working principle: This type of sewage treatment device can be implemented in the following ways; First, sewage from multiple locations in the city is transported through pipelines and eventually collected in one place. It is then transported to the septic tank 2 through the feed pipe 3. Since the sewage is viscous, it easily adheres to the inner wall of the pipeline. Therefore, when it is transported in the same pipeline, the adhesion phenomenon becomes more obvious. At this time, it is necessary to effectively clean the inner wall of the pipeline. The cleaning operation can be carried out by the cooperation of the inner support mechanism 4 and the cleaning mechanism 5. The inner support mechanism 4 is placed inside the pipeline, and the other end is connected with a rope for easy control. Since the diameter of the pipeline is different, the tension spring 407 can be used to adjust the angle of the two sets of anti-force inclined plates 404, thereby adjusting the exact position of the roller 406. This ensures that the rollers 406 in all directions of the inner support mechanism 4 can effectively fit against the inner wall of the pipeline. Since the humidity inside the pipeline is high, the design of the motor housing 408 can effectively ensure that the second motor 410 is not easily affected by moisture. Next, the cleaning mechanism 5 will be driven to rotate by the second motor 410. The front push plate 501 will rotate by the second motor 410. With the connection structure of the transmission column 502, the resistance ring 503 will rotate in coordination with the front push plate 501. At this time, the resistance side block 504 and the arc-shaped side scraper 505 around the resistance ring 503 can be driven. Through the inclined structure design of the arc-shaped side scraper 505, the stains adhering to the inner wall of the pipe can be removed. Then, after the manure is transported to the manure collection tank 2 through the pipeline, it will inevitably contain solid residues or large particles, which will have a certain impact on the fermentation process. Therefore, the manure transported to the manure collection tank 2 needs to be preliminarily screened. At this time, the screening mechanism 8 is used to cooperate in the operation. After the manure enters the annular sieve cylinder 809 through the pipeline, it will be screened. Small particles and liquids will flow into the receiving sedimentation tank 9 through the holes on the surface of the annular sieve cylinder 809, while solid residues or large particles will be blocked and accumulated by the annular sieve cylinder 809. At the same time, in order to avoid too much manure concentrating in one place of the annular sieve cylinder 809 and causing blockage, the first motor 6 needs to be operated to drive the transmission belt 801 to rotate, and drive the transmission rod 803 and the annular sieve cylinder 809 to rotate together. The centrifugal force generated by the rotation can remove the manure adhering to the annular sieve cylinder 809, thereby improving the manure screening efficiency. Finally, the annular filter cylinder 809 is susceptible to corrosion due to long-term use and needs to be replaced regularly. This can be done by removing the top cover 7 and taking out the side clip 807 from the groove at the bottom of the top cover 7. At the same time, the other end of the annular filter cylinder 809 can be removed and replaced by using the sliding structure of the T-shaped clip 808 and the limiting slide groove 17. The filtered manure will fall into the receiving sedimentation tank 9 for further sedimentation.

10. A centralized resource-based treatment technology for urban sewage, characterized in that, The urban sewage centralized resource utilization treatment device according to any one of claims 1-9 includes the following steps: S1: First, sewage from multiple locations in the city is transported through pipelines and eventually collected in one place, and then transported to the septic tank (2) through the feed pipe (3); S2: Since the feces are viscous and easily adsorbed onto the inner wall of the pipe, the adhesion phenomenon becomes more obvious when they are transported in the same pipe. At this time, it is necessary to effectively clean the inner wall of the pipe. The cleaning operation can be carried out by the cooperation of the inner support mechanism (4) and the cleaning mechanism (5). S3: Place the inner support mechanism (4) inside the pipe, and connect the other end with a rope for easy control. Since the pipe diameter is different, the tension spring (407) can be used to adjust the angle of the two sets of anti-force inclined plates (404), thereby adjusting the exact position of the roller (406) to ensure that the rollers (406) in all directions of the inner support mechanism (4) can effectively fit against the inner wall of the pipe. Since the humidity inside the pipe is high, the design of the motor housing (408) can effectively ensure that the second motor (410) is not easily damp. S4: Driven by the second motor (410), the cleaning mechanism (5) will rotate. The front push plate (501) will rotate through the second motor (410). Using the connection structure of the transmission column (502), the resistance ring (503) will rotate in coordination with the front push plate (501). At this time, the resistance side block (504) and the arc-shaped side shovel (505) around the resistance ring (503) can be driven. Through the inclined structure design of the arc-shaped side shovel (505), the stains adhering to the inner wall of the pipe can be removed. S5: After the sewage is transported to the collection tank (2) through the pipeline, it will inevitably contain solid residues or large particles, which will have a certain impact on the fermentation process. Therefore, the sewage transported to the collection tank (2) needs to be preliminarily screened. At this time, the screening mechanism (8) is used to cooperate with the operation. After the sewage enters the annular filter cylinder (809) through the pipeline, it will be screened. Small particles and liquids will flow into the receiving sedimentation tank (9) through the holes on the surface of the annular filter cylinder (809), while solid residues or large particles will be blocked and accumulated by the annular filter cylinder (809). At the same time, in order to avoid too much sewage from being concentrated in one place of the annular filter cylinder (809) and causing blockage, the first motor (6) needs to be used to drive the transmission belt (801) to rotate, and drive the transmission rod (803) and the annular filter cylinder (809) to rotate together. The centrifugal force generated by the rotation can be used to remove the sewage adhering to the annular filter cylinder (809) and improve the sewage screening efficiency. S6: The annular funnel (809) is susceptible to corrosion after long-term use and needs to be replaced regularly. At this time, the side clip (807) can be removed from the groove at the bottom of the top cover (7) by disassembling the top cover (7). At the same time, the other end of the annular funnel (809) can be removed and replaced by using the sliding structure of the T-shaped clip (808) and the limiting slide groove (17). The filtered sewage will fall into the receiving sedimentation tank (9) for further sedimentation. The sedimented sewage will be transported to the fermentation tank (12) by the high-level pipe (11) and fermentation will be achieved by utilizing the influence of microorganisms and other environmental factors. Finally, it will flow into the storage tank (15) by the low-level pipe (14).
