Description

Technical Field

[0001] This invention relates to the field of wastewater purification, specifically to an integrated anti-clogging microbial wastewater purification and deodorization treatment device. Background Technology

[0002] Existing integrated microbial wastewater treatment equipment typically includes functional units such as a coarse screen zone, a fine screen zone, a sedimentation zone, and a microbial reaction zone. However, significant defects still exist in actual operation: after wastewater is initially intercepted by the coarse and fine screen zones, it enters the sedimentation zone. If the scum is not completely removed, it will flow into the subsequent microbial reaction zone along with the supernatant.

[0003] The microbial reaction zone is filled with a large number of microbial carriers for attaching and degrading biofilms of pollutants. However, residual scum easily adheres to and coats the surface of the microbial carriers, forming a dense layer that not only blocks the pores and gaps of the microbial carriers but also severely hinders the transfer of oxygen released by the bottom aeration system into the water, causing aerobic microorganisms to lose activity or even die due to lack of oxygen.

[0004] In addition, scum continuously decomposes under anaerobic conditions to produce volatile odorous gases such as hydrogen sulfide and ammonia. Traditional equipment is mostly open in structure and lacks closed deodorization measures that are synchronized with scum scraping, which causes the odor to escape, which not only deteriorates the operating environment but may also inhibit microbial metabolism.

[0005] Therefore, there is a need for an integrated anti-clogging microbial wastewater purification and deodorization treatment device to solve the problem of incomplete removal of scum in the sedimentation zone and the decline in the treatment efficiency of microbial carriers caused by odor emission. Summary of the Invention

[0006] To address the problems existing in the prior art, an integrated anti-clogging microbial wastewater purification and deodorization treatment device is provided. Through an integrated multi-zone layout, combined with the foam scraping mechanism and the linkage disturbance of the rotatable carrier, it effectively prevents clogging and enhances solid-liquid separation. With the help of aeration and deodorization, the quality of the effluent is improved.

[0007] To address the problems of existing technologies, this invention provides an integrated anti-clogging microbial wastewater purification and deodorization treatment device, comprising a treatment tank. The treatment tank is divided sequentially along the water flow direction into a coarse screen zone, a fine screen zone, a sedimentation zone, and a microbial reaction zone. A scum discharge trough is provided at one end of the sedimentation zone adjacent to the microbial reaction zone. A skimming mechanism is provided above the sedimentation zone to remove surface scum. The skimming mechanism includes a sliding frame that can move along the length of the sedimentation zone. Two guide rails are symmetrically arranged above the sedimentation zone along its width, and the sliding frame is slidably disposed between the two guide rails. A scraper plate is mounted on the sliding frame. One end of the slag plate is inclined from the side near the slag discharge trough to the other side and is immersed below the liquid surface of the sedimentation zone. Both ends of the slag scraper extend to the inner wall of the sedimentation zone. A mounting frame is horizontally provided in the microbial reaction zone.

[0009] Preferably, the upper and lower sidewalls of the ventilation slot are respectively provided with an upper air guide plate and a lower air guide plate, a front air guide channel is formed between the upper air guide plate and the slag scraper, and a rear air guide channel is formed between the lower air guide plate and the slag scraper.

[0010] Preferably, the mounting bracket is provided with a distance sensor on the side near the sliding bracket, and the sliding bracket is provided with a sensing point on the corresponding side for real-time detection of the position of the sliding bracket.

[0011] Preferably, the microbial carrier is provided with an upper rotating shaft and a lower rotating shaft arranged vertically along the mounting frame. The upper rotating shaft and the lower rotating shaft are rotatably connected to the mounting frame through bearings. The top end of the upper rotating shaft is provided with the linkage structure that cooperates with the movable frame, which is used to drive the microbial carrier to rotate when the movable frame moves.

[0012] Preferably, the linkage structure includes a side block and a pushing block. The side block is fixedly installed on the top side of the upper rotating shaft, and the pushing block is fixedly installed in front of the corresponding side block of the movable frame. A torsion spring is sleeved on the lower half of the lower rotating shaft, and the two ends of the torsion spring are fixedly connected to the lower rotating shaft and the mounting frame, respectively.

[0013] Preferably, the elastic connector is a compression spring, the rear end of the mounting frame is provided with a guide plate, and the movable frame is symmetrically provided with two guide rods passing through the guide plate on the side away from the sliding frame.

[0014] Preferably, the scraper is rotatably connected to the sleeve via a central shaft, and a return spring is provided between the upper air guide plate and the scraper. One end of the return spring is fixedly connected to the lower surface of the upper air guide plate, and the other end is fixedly connected to the upper surface of the scraper, which is used to pull the scraper upward away from the liquid surface during non-working strokes.

[0015] Preferably, the upper air guide plate is provided with a limiting cylinder, the output end of the limiting cylinder extends downward through the upper air guide plate, and the lower extension end of the limiting cylinder is provided with an abutting block that fits against the upper surface of the slag scraper plate, which is used to press the slag scraper plate downward and immerse it in the liquid surface during the slag scraping stroke.

[0016] Preferably, the lower air guide plate is provided with a lower limit block to limit the downward swing angle of the slag scraper.

[0017] The advantages of this application compared to the prior art are:

[0018] 1. This invention achieves efficient solid-liquid separation by sequentially setting up a coarse screen zone, a fine screen zone, a sedimentation zone, and a microbial reaction zone within an integrated treatment device. A full-width skimmer and sludge discharge trough are configured in the sedimentation zone, combined with a bottom sludge collection slope and sludge discharge pipe. Simultaneously, the skimmer and the rotatable microbial carrier in the microbial reaction zone are connected via a movable frame and linkage structure, along with elastic connectors, to synchronously trigger periodic disturbances in the microbial carrier during the skimming action, preventing clogging. This effectively prevents scum from clogging the microbial carrier. An aeration system is installed in the lower half of the microbial reaction zone to supply oxygen, followed by a clarifier to complete secondary solid-liquid separation, thereby improving the effluent quality.

[0019] 2. This invention forms an internal air intake chamber by installing a sleeve, central shaft, and scraper plate on the sliding frame of the skimming mechanism. Upper and lower air guide plates are positioned on the upper and lower sides of the scraper plate to construct front and rear air guide channels. A negative pressure source is connected to the air intake interface at the top of the sleeve, enabling directional capture and synchronous suction of odor throughout the skimming process. Simultaneously, the angle of the scraper plate entering the water is precisely controlled by the combined action of a limiting cylinder's downward-pushing contact block and a return spring. The maximum downward swing angle is limited by a lower limiting block on the lower air guide plate, ensuring effective skimming while preventing the closure of the front and rear air guide channels. During the return stroke, the scraper plate automatically detaches from the water surface, reducing resistance and preventing scum from being carried back, thus improving deodorization efficiency and operational stability.

[0020] 3. This invention achieves precise position detection by setting up a pressure-applying part and a pressure-receiving part between the sliding frame and the movable frame, and cooperating with a distance sensor and sensing point, ensuring that the scraping is in place and synchronized with the linkage. The movable frame forms an elastic reset mechanism through a guide rod and a compression spring, ensuring stable translation and reliable return. The pushing block on the movable frame and the side block on the upper rotating shaft of the microbial carrier form a linkage structure, driving the microbial carrier to rotate around the vertical axis. At the same time, the torsion spring sleeved on the lower rotating shaft provides rotational torque, so that the microbial carrier rotates forward during the scraping stroke and automatically resets during the return stroke, realizing periodic shaking, effectively removing attached impurities and excessively thick biofilm, preventing the microbial carrier from clogging, and ensuring long-term efficient operation of the microbial reaction zone.

[0034] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0035] See Figures 1 to 9As shown, an integrated anti-clogging microbial wastewater purification and deodorization treatment device includes a treatment tank 1. The treatment tank 1 is divided into a coarse screen zone 2, a fine screen zone 3, a sedimentation zone 4, and a microbial reaction zone 5 along the water flow direction. A slag discharge trough 41 is provided at one end of the sedimentation zone 4 adjacent to the microbial reaction zone 5. A skimming mechanism 7 is provided above the sedimentation zone 4 to remove surface scum. The skimming mechanism 7 includes a sliding frame 71 that can move along the length of the sedimentation zone 4. Two guide rails 42 are symmetrically arranged above the sedimentation zone 4 along its width direction, and the sliding frame 71 is slidably disposed between the two guide rails 42. A slag scraper 72 is installed on the sliding frame 71. One end of the slag scraper 72 is inclined from the side near the slag discharge trough 41 to the other side and immersed below the liquid surface of the sedimentation zone 4. Both ends of the slag scraper 72 extend to the inner wall of the sedimentation zone 4. A mounting frame 51 is horizontally arranged within the microbial reaction zone 5. Several rotatable microbial carriers 52 are evenly spaced on the mounting frame 51. A movable frame 53, capable of moving along the scraping direction, is located at the top of the mounting frame 51. A linkage structure 54 is provided between each microbial carrier 52 and the movable frame 53. A pressure-applying part 711 is provided on the side of the sliding frame 71 closest to the movable frame 53, and a pressure-receiving part 712, cooperating with the pressure-applying part 711, is provided on the corresponding side of the movable frame 53. An elastic connector 531, connected to the mounting frame 51, is provided on the side of the movable frame 53 furthest from the sliding frame 71.

[0036] The sliding frame 71 is composed of a connecting plate 713 and two sliders 714. Each slider 714 is slidably mounted on a guide rail 42, and the connecting plate 713 is fixedly connected between the two sliders 714.

[0037] Both the sedimentation zone 4 and the lower half of the microbial reaction zone 5 are equipped with an aeration system 8.

[0038] The bottom of the sedimentation zone 4 is provided with a sludge collection slope 43, and a sludge discharge pipe is provided at the lowest point of the sludge collection slope 43 for collecting and discharging the settled sludge.

[0039] The microbial reaction zone 5 is connected to a clarification tank 6, which is used to further intercept suspended solids and ensure that the effluent water quality meets the standards.

[0040] Purification Process: The wastewater is treated sequentially in coarse screen zone 2, fine screen zone 3, sedimentation zone 4, and microbial reaction zone 5. The wastewater first enters the front end of the integrated treatment equipment, flowing through coarse screen zone 2 and fine screen zone 3. In coarse screen zone 2, larger floating objects such as plastic bags and branches are intercepted. The water then flows into fine screen zone 3, where smaller suspended impurities and fibrous materials are further removed, effectively reducing the risk of clogging in subsequent units.

[0041] The pretreated wastewater flows into sedimentation zone 4, where solid-liquid separation occurs: heavier inorganic particles settle to the bottom of the tank under gravity and slide down the bottom sludge collection slope 43 to the lowest point, where they are periodically discharged through the sludge discharge pipe. Simultaneously, lighter scum, such as grease, foam, and organic debris, floats to the surface through the corresponding aeration system 8. At this point, the skimmer mechanism 7 is activated, and the sliding frame 71 moves back and forth along the length of sedimentation zone 4 on both sides of the guide rails 42. The skimmer plates 72 extend to the inner wall of sedimentation zone 4 at both ends, ensuring full coverage. The lower edge of the skimmer plates 72 is submerged below the liquid surface, continuously pushing the scum on the surface to the sludge discharge trough 41 at the end for collection.

[0042] Meanwhile, the skimming mechanism 7 is mechanically linked with the microbial reaction zone 5: when the sliding frame 71 reaches the end of its stroke near the microbial reaction zone 5, its side pressure part 711 contacts the pressure-receiving part 712 on the movable frame 53, pushing the movable frame 53 forward to overcome the resistance of the elastic connector 531. The movable frame 53 is connected to each microbial carrier 52 through a linkage structure 54. Its movement causes each microbial carrier 52 to rotate synchronously at a certain angle, shaking off any residual impurities or excessively thick biofilm that may be attached. After completing the skimming action, the sliding frame 71 returns in the opposite direction, the pressure part 711 disengages from the pressure-receiving part 712, the elastic connector 531 releases its stored energy, driving the movable frame 53 to reset, and the microbial carrier 52 rotates accordingly, forming periodic disturbances that effectively prevent clogging of the packing pores.

[0043] The entire microbial reaction zone 5 is equipped with a horizontal mounting frame 51, on which multiple rotatable high specific surface area microbial carriers 52 are arranged at equal intervals to enrich and degrade pollutants into biofilms. The lower half of the microbial reaction zone 5 is continuously supplied with dissolved oxygen and promotes water circulation through a corresponding aeration system 8, ensuring efficient metabolism of aerobic microorganisms.

[0044] The mixed liquor treated in the microbial reaction zone 5 flows into the subsequent clarifier 6, where secondary solid-liquid separation occurs. The detached biofilm and suspended sludge settle, and the supernatant is collected via an overflow weir and discharged after meeting standards. This process not only achieves efficient removal of pollutants such as organic matter and ammonia nitrogen, but also fundamentally solves the problems of unstable effluent quality caused by scum carrying and microbial carrier 52 blockage through a comprehensive treatment process including front-end fine interception, mid-stage scum removal, back-end anti-clogging and disturbance of the microbial carrier 52, and end-stage clarification, thereby improving the wastewater purification effect.

[0045] See Figures 2 to 4 and Figures 8 to 12As shown, a sleeve 73 is fixedly provided on the sliding frame 71 along its length direction. A central shaft 731 is coaxially provided inside the sleeve 73. The upper end of the scraper plate 72 is fixedly connected to the central shaft 731. The sleeve 73 and the scraper plate 72 enclose and form an air suction chamber. An air vent is provided at the scraper plate 72. Several air suction ports 732 are provided on the top of the sleeve 73 along its axial direction.

[0046] During the operation of the skimming mechanism 7, the sliding frame 71 moves along the length of the sedimentation zone 4, and the sleeve 73 fixed on it moves synchronously with the slag scraper 72.

[0047] When the negative pressure source draws air through the multiple suction ports 732 arranged axially at the top of the sleeve 73, a negative pressure environment is formed in the suction chamber. At this time, the scraper plate 72 disturbs the water surface while pushing away the scum, releasing volatile odorous gases such as hydrogen sulfide and ammonia. These gases are quickly drawn into the suction chamber through the ventilation slots on the scraper plate 72 and then centrally discharged to the external deodorization unit, such as a biological filter or activated carbon device, through the suction ports 732. This achieves simultaneous scraping and air intake, effectively preventing odors from escaping in the sedimentation zone 4, improving the operating environment, and avoiding the inhibitory effect of toxic gases on the subsequent microbial reaction zone 5.

[0048] See Figure 2 , Figure 3 and Figures 8 to 12 As shown, the upper and lower sidewalls of the ventilation slot are respectively provided with an upper air guide plate 721 and a lower air guide plate 722. A front air guide channel is formed between the upper air guide plate 721 and the slag scraper 72, and a rear air guide channel is formed between the lower air guide plate 722 and the slag scraper 72.

[0049] During the scum scraping operation, the scum scraper 72 disturbs the liquid surface as it pushes away the floating scum, releasing odorous gases that need to be efficiently captured. A front air guide channel is formed between the upper air guide plate 721 and the scum scraper 72 to guide the airflow generated by the disturbance at the front of the scum scraper 72 in its direction of movement. A rear air guide channel is formed between the lower air guide plate 722 and the scum scraper 72 to capture the escaping gases generated behind the scum scraper 72 due to scum accumulation. The two airflows converge into the suction chamber through the front and rear air guide channels and are finally drawn away by the negative pressure system through the suction port 732 at the top of the sleeve 73. This achieves directional collection of odorous gases throughout the entire scum scraping process and all areas, improving deodorization efficiency.

[0050] See Figure 6 As shown, the mounting bracket 51 is provided with a distance sensor 511 on the side near the sliding bracket 71, and the sliding bracket 71 is provided with a sensing point 512 on the corresponding side for real-time detection of the position of the sliding bracket 71.

[0051] When the sliding frame 71 moves towards the microbial reaction zone 5 to the preset working position, that is, when the pressure part 711 is about to contact or just contacts the pressure part 712 of the movable frame 53, the sensing point 512 enters the detection range of the distance sensor 511. The distance sensor 511 outputs a position signal to the control system in real time. This signal is used to confirm that the scraper 72 has reached the effective working end point and control the scraper 72 to move into place.

[0052] During the return phase, the distance sensor 511 can also determine whether the sliding frame 71 has disengaged from the linkage area, thereby ensuring that the movable frame 53 can be reliably reset and realizing the coordinated operation between the sliding frame 71 and the movable frame 53.

[0053] See Figure 6 and Figure 7 As shown, the microbial carrier 52 is provided with an upper rotating shaft 521 and a lower rotating shaft 522 arranged vertically along the mounting frame 51. The upper rotating shaft 521 and the lower rotating shaft 522 are rotatably connected to the mounting frame 51 through bearings 5211. The top end of the upper rotating shaft 521 is provided with the linkage structure 54 that cooperates with the movable frame 53, which is used to drive the microbial carrier 52 to rotate when the movable frame 53 moves.

[0054] When the sliding frame 71 moves to the end of its stroke near the microbial reaction zone 5, the pressure part 711 on it pushes the movable frame 53 to overcome the resistance of the elastic connector 531 and move it horizontally along the scraping direction. The movement of the movable frame 53 is acted on the top of the upper rotating shaft 521 of each microbial carrier 52 through the linkage structure 54.

[0055] Specifically, each microbial carrier 52 is stably supported by an upper rotating shaft 521 and a lower rotating shaft 522 arranged vertically along the mounting frame 51, and is connected to the mounting frame 51 with low friction via bearings 5211, ensuring that the microbial carrier 52 can rotate freely around the vertical axis.

[0056] When the movable frame 53 moves, the linkage structure 54 drives the entire microbial carrier 52 to rotate around the rotation axis formed by the upper rotating shaft 521 and the lower rotating shaft 522 at a certain angle. This rotation effectively shakes off scum, fibers, or excessively thick biofilm adhering to the surface of the microbial carrier 52, preventing pore blockage. Subsequently, the sliding frame 71 retracts, the pressure is released, the elastic connector 531 drives the movable frame 53 to reset, the linkage structure 54 is released, and the microbial carrier 52 rotates back to its initial position, completing one cycle of anti-clogging disturbance and ensuring the long-term efficient operation of the microbial reaction zone 5.

[0057] See Figure 6 and Figure 7As shown, the linkage structure 54 includes a side block 541 and a pushing block 542. The side block 541 is fixedly installed on the top side of the upper rotating shaft 521, and the pushing block 542 is fixedly installed in front of the movable frame 53 corresponding to the side block 541. The lower half of the lower rotating shaft 522 is fitted with a torsion spring 5221, and the two ends of the torsion spring 5221 are fixedly connected to the lower rotating shaft 522 and the mounting frame 51, respectively.

[0058] The movable frame 53 is provided with a slide groove 532 for the upper rotating shaft 521 to move freely during the reciprocating movement of the movable frame 53.

[0059] When the scraping mechanism reaches the end of its stroke, the sliding frame 71 drives the pressure application part 711 to push the movable frame 53 to move horizontally along the scraping direction. At this time, the pushing block 542 fixed on the movable frame 53 moves synchronously with it and contacts the side block 541 located on the top side of the upper rotating shaft 521, thereby applying a horizontal thrust to the side block 541, forcing the upper rotating shaft 521 together with the entire microbial carrier 52 to rotate around the vertical axis.

[0060] Meanwhile, the torsion spring 5221, fitted onto the lower half of the lower rotating shaft 522, is torsionally charged to store energy. One end of the spring is fixed to the lower rotating shaft 522, and the other end is fixed to the mounting frame 51, providing an elastic torque for the microbial carrier 52 to rotate and reset. When the sliding frame 71 completes the scraping action and begins its return stroke, the pressure part 711 disengages from the pressure-bearing part 712, and the movable frame 53 moves in the opposite direction under the action of the elastic connector 531, causing the pushing block 542 to retract. At this time, the torsion spring 5221 releases its stored elastic potential energy, driving the lower rotating shaft 522 and the entire microbial carrier 52 to rotate back to their initial position, achieving periodic vibration to prevent blockage.

[0061] See Figure 6 As shown, the elastic connector 531 is a compression spring, the rear end of the mounting frame 51 is provided with a guide plate 5311, and the movable frame 53 is symmetrically provided with two guide rods 5312 passing through the guide plate 5311 on the side away from the sliding frame 71. Each guide rod 5312 is fitted with a compression spring. One end of the compression spring is fixedly connected to the guide plate 5311, and the other end is fixedly connected to the movable frame 53.

[0062] During the slag scraping process, when the sliding frame 71 moves to the end position near the microbial reaction zone 5, its pressure part 711 pushes the movable frame 53 to move against elastic resistance. At this time, the two guide rods 5312 symmetrically arranged on the rear side of the movable frame 53 slide linearly along the guide plate 5311 at the rear end of the mounting frame 51, ensuring that the movable frame 53 moves smoothly and without deviation. The compression spring sleeved on each guide rod 5312 is gradually compressed during the movement of the movable frame 53, storing elastic potential energy.

[0063] When the scraping action is completed and the sliding frame 71 begins its return stroke, the pressure-applying part 711 disengages from the pressure-receiving part 712, the compression spring releases its stored energy, generating a reverse thrust that drives the movable frame 53 to precisely return to its initial position along the guide rod 5312. This not only provides stable guidance for the movable frame 53 but also ensures that the linkage mechanism accurately returns to its original position after each action through the reliable restoring force of the compression spring, thereby guaranteeing the repeatability of the periodic disturbance of the microbial carrier 52 and its anti-clogging effect.

[0064] See Figure 10 and Figure 11 As shown, the scraper plate 72 is rotatably connected to the sleeve 73 via the central shaft 731. A return spring 7211 is provided between the upper air guide plate 721 and the scraper plate 72. One end of the return spring 7211 is fixedly connected to the lower surface of the upper air guide plate 721, and the other end is fixedly connected to the upper surface of the scraper plate 72. It is used to pull the scraper plate 72 upward and away from the liquid surface during the non-working stroke.

[0065] During the non-working stroke, i.e., the return stroke, the sliding frame 71 begins to move in the reverse direction. The external downward pressure is released, and the return spring 7211, with its elastic force, pulls the upper part of the scraper plate 72 upwards, causing the scraper plate 72 to rotate upwards around the central axis 731. This causes its lower edge to quickly detach from the liquid surface of the sedimentation zone 4. This effectively avoids the scraper plate 72 dragging the water surface or causing unnecessary friction with the scum during the return stroke, reducing operating resistance, reducing energy consumption, and preventing the collected scum from being carried back.

[0066] See Figure 2 and Figure 12 As shown, the upper air guide plate 721 is provided with a limiting cylinder 7221. The output end of the limiting cylinder 7221 extends downward through the upper air guide plate 721. The lower extension end of the limiting cylinder 7221 is provided with an abutting block 7222 that fits against the upper surface of the scraper plate 72, which is used to press the scraper plate 72 downward into the liquid surface during the scraping stroke.

[0067] Before the slag scraping stroke begins, the limit cylinder 7221 is activated, and its output end extends downward from above the upper air guide plate 721 through the reserved hole, driving the lower extension end of the contact block 7222 to move downward synchronously. The contact block 7222 precisely presses against the upper surface of the slag scraper 72 and applies a downward force, forcing the slag scraper 72, which was originally in the state of being pulled up by the return spring 7211, to rotate downward around the central axis 731 until its lower edge is immersed below the liquid surface of the sedimentation zone 4 at a set angle. This downward pressure and the upward pulling force of the return spring 7211 form a dynamic balance, so that the slag scraper 72 is stably maintained in the optimal working posture, ensuring effective contact and pushing of the slag.

[0068] When the scraping action is completed and the sliding frame 71 enters the return phase, the limit cylinder 7221 retracts, the contact block 7222 disengages from the scraper plate 72, and the return spring 7211 then guides the scraper plate 72 to return upward and leave the water surface, creating conditions for a low-resistance return stroke. Through the coordinated control of the limit cylinder 7221 and the return spring 7211, precise adjustment and automatic switching of the scraper plate 72's water entry depth and working angle are achieved.

[0069] See Figure 10 and Figure 11 As shown, the lower air guide plate 722 is provided with a lower limit block 7223, which is used to limit the downward swing angle of the scraper plate 72.

[0070] During the slag scraping stroke, when the limiting cylinder 7221 pushes the slag scraper 72 to swing downwards to immerse itself in the liquid surface, the slag scraper 72 continues to rotate downwards around the central axis 731. To prevent excessive downward swinging that could lead to structural collision, excessive water flow disturbance, or blockage of the rear air guide channel, a lower limiting block 7223 is provided on the lower air guide plate 722.

[0071] When the scraper blade 72 swings down to the preset working angle, it contacts and is blocked by the lower limit block 7223, thus precisely limiting its maximum downward swing angle. This not only protects the scraper blade 72 from mechanical damage but also ensures that the front and rear air guide channels always maintain an effective opening, keeping the airflow unobstructed and ensuring efficient odor extraction. At the same time, it allows the scraper blade 72 to complete the scum removal operation at a stable and appropriate water depth.

[0072] This invention achieves efficient solid-liquid separation by integrating a coarse screen zone 2, a fine screen zone 3, a sedimentation zone 4, and a microbial reaction zone 5. A full-width skimmer 7, a slag discharge trough 41, a sludge collection ramp 43, and a sludge discharge pipe are installed in the sedimentation zone 4. The skimmer 7's sliding frame 71 is equipped with a sleeve 73, a central shaft 731, and a skimmer 72. These, along with an upper air guide plate 721 and a lower air guide plate 722, form a front air guide channel and a rear air guide channel. Combined with the suction port 732 and a negative pressure source, it achieves directional and synchronous suction of odorous gases. The entry angle and return disengagement of the skimmer 72 are controlled collaboratively by a limit cylinder 7221, a return spring 7211, and a lower limit block 7223.

[0073] Meanwhile, the pressure-applying part 711 of the sliding frame 71 is linked with the pressure-receiving part 712 of the movable frame 53. With the precise triggering action of the distance sensor 511, the movable frame 53 is stably translated and reset via the guide rod 5312 and the compression spring. Its pushing block 542 pushes the side block 541 of the upper rotating shaft 521 of the microbial carrier 52, which, together with the torsion spring 5221 of the lower rotating shaft 522, drives the carrier to rotate periodically in both directions, effectively shaking off the attached substances, preventing blockage, and ensuring the aeration oxygen supply efficiency and stable effluent water quality.

[0074] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of protection of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
