Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of water conservancy projects, and in particular, to a water conservancy project sewage treatment device. Background Art

[0002] A water conservancy wastewater treatment plant is a complete set of equipment or systems used to remove pollutants (such as organic matter, suspended solids, heavy metals, pathogens, etc.) from water in rivers and conservancies. Its purpose is to purify wastewater to a level suitable for discharge or reuse. Its core objectives are to prevent water pollution, protect the water environment, and achieve water resource recycling.

[0003] The patent with announcement number CN212504360U discloses a sewage treatment device that can recycle sludge, which relates to the field of sewage treatment technology. In view of the problem that the current sewage treatment device has unqualified sludge recovery process when in use, which easily leads to environmental pollution, the following scheme is proposed, which includes a dehydration stirring tank and a sludge collection tank, wherein a suction pipe is fixedly installed at the center point of the upper end of the sludge collection tank, and the suction pipe is fixedly connected to a feed pipe at the upper end position away from the sludge collection tank, and a sludge extraction pump is fixedly installed at the side wall position of the feed pipe close to the suction pipe, and the feed pipe is fixedly connected to a dehydration stirring tank at the side wall position away from the sludge collection tank, and a feed pipe is fixedly installed at the upper end position of the side wall of the sludge collection tank. The patent structure is novel and solves the problem that the current sewage treatment device has unqualified sludge recovery process when in use, which easily leads to environmental pollution. However, the above device cannot well control the amount of flocculant added and the mixing quality when used, so a water conservancy project sewage treatment equipment is proposed to solve the above problems. Summary of the Invention

[0004] To overcome the above-mentioned defects, an embodiment of the present invention provides a water conservancy project sewage treatment equipment, which solves the technical problem in the prior art that the amount of flocculant added and the mixing quality cannot be well controlled.

[0005] According to one aspect, at least one embodiment of the present invention provides a water conservancy project sewage treatment equipment, including a tank body and a frame, a discharge port is provided on the left side of the tank body, a pumping assembly is fixedly connected to the top of the tank body, a mud discharge mechanism is provided at the bottom of the inner wall of the tank body, an adsorption tank is provided inside the tank body, a stirring and dosing mechanism is provided at the bottom of the frame, and a surging mechanism is provided inside the tank body; the stirring and dosing mechanism includes: a motor bracket, a motor, a rotating shaft, and a stirring paddle. The motor bracket is fixedly connected to the top of the frame, the motor is fixedly connected to the top of the motor bracket, the rotating shaft is fixedly connected to the output end of the motor, and the stirring paddle is fixedly connected to the circumferential surface of the rotating shaft. The stirring and dosing mechanism also includes: a medicine discharge box, a medicine discharge pipe, a baffle, and a sleeve. The medicine discharge box is fixedly installed on the left inner wall of the tank body, the medicine discharge pipe is slidably connected to the inside of the medicine discharge box, the sleeve is fixedly connected to the inside of the medicine discharge box, the baffle is fixedly connected to the circumferential surface of the medicine discharge pipe, the medicine discharge pipe is slidably connected to the inner wall of the sleeve, and the end of the medicine discharge pipe away from the baffle is fixedly connected to a spring.

[0006] For example, in a water conservancy project sewage treatment equipment provided by at least one embodiment of the present invention, the mud discharge mechanism includes: mud pushing plate 1, mud pushing plate 2, connecting rod 1, slide rail 1, slide rail 2, connecting rod 2, bottom plate 1, bottom plate 2, and connecting seat, the mud pushing plate 1 is fixedly connected to the left side of connecting rod 1, the mud pushing plate 2 is fixedly connected to the left side of connecting rod 2, the slide rail 1 is fixedly connected to the bottom of bottom plate 2, the bottom plate 1 and bottom plate 2 are fixedly connected to the bottom of the pool body, the connecting rod 2 is slidably connected to the bottom of slide rail 1, the connecting rod 1 and connecting rod 2 are fixedly connected to the left side of the connecting seat, the slide rail 2 is fixedly connected to the bottom of the pool body, and the connecting seat is slidably connected to the surface of slide rail 2.

[0007] After the sewage is discharged into the pool, the motor starts and drives the rotating shaft to rotate. The rotation of the rotating shaft drives the stirring paddle to rotate. The stirring paddle stirs the sewage. During the stirring process, the stirring paddle will contact the baffle. Continuous rotation of the stirring paddle pushes the baffle. The baffle moves outward, driving the medicine discharge tube to move outward, stretching the spring and exposing the liquid outlet hole on the medicine discharge tube. At this time, the flocculant inside the medicine discharge box flows out and mixes with the sewage with the stirring of the stirring paddle.

[0008] When the agitator moves away from the stop lever, the spring resets and drives the discharge pipe back, retracting it and stopping the discharge. This reciprocating motion prevents overdosing during manual dosing, which can lead to excessive concentration of the drug in a local area, making it difficult to diffuse and wasting drug costs. This device allows for multiple, small additions of the drug, which helps gradually disperse the drug, reduces the risk of agglomeration, and improves mixing quality.

[0009] Dosing small amounts multiple times can avoid manual dosing, which can lead to over-control of the dosage. Excessive dosing can lead to localized concentration of the agent, hindering rapid diffusion, wasting the agent and increasing costs. Insufficient dosing can prevent the wastewater from fully flocculating and settling, impacting treatment quality. Dosing small amounts multiple times helps gradually disperse the agent, reducing the risk of agglomeration and improving mixing quality.

[0010] The mud discharge mechanism also includes: a first protrusion, a mud discharge plate, a second protrusion, and an elastic stopper. The mud discharge plate is hinged at the bottom of the pool body, the first protrusion is fixedly connected to the surface of the mud discharge plate, the second protrusion is fixedly connected to the bottom of the second connecting rod, and the elastic stopper is fixedly connected to the inner wall of the frame.

[0011] After the sewage has been fully precipitated, the pumping assembly pumps the water into the adsorption tank. Motor 2 starts and drives the cam to rotate. The rotation of the cam drives the connecting rod to move along the circumferential direction of the cam. The movement of the connecting rod drives the connecting block to move. The movement of the connecting block drives the connecting seat to move. The connecting seat is constrained by the second slide rail and can only do reciprocating motion along the direction of the second slide rail. When the connecting seat moves to the left side of the pool body, it will drive connecting rod 1 and slide rail 1 to move to the left. Connecting rod 1 pushes mud pusher 1, and slide rail 1 pushes mud pusher 2 to move. Mud pusher 1 pushes the settled silt from bottom plate 2 to bottom plate 1, and mud pusher 2 pushes the silt from bottom plate 1 to the discharge port for discharge.

[0012] At the same time, when the connecting rod 2 moves to the left, the protrusion 2 will touch the protrusion 1, and the continuous movement of the protrusion 2 will squeeze the protrusion 1. The protrusion 2 squeezes the protrusion 1, causing the mud discharge plate in contact with it to deviate downward and compress the elastic stopper in contact with the mud discharge plate. When the connecting seat moves back, the mud pusher plate 2 pushes the silt pushed down by the mud pusher plate 1 to the gap between the bottom plate 1 and the bottom plate 2 and falls onto the mud discharge plate. At the same time, the protrusion 2 moves away from the protrusion 1, and the mud discharge plate loses its constraint. The elastic stopper resets and bounces the mud discharge plate back. The reciprocating up and down shaking of the mud discharge plate will discharge the silt better and improve the discharge efficiency.

[0013] Through the mutual cooperation among: connecting rod 1, slide rail 1, slide rail 2, connecting rod 2, protrusion 1, mud discharge plate, protrusion 2 and elastic stopper, the sludge is discharged better and the discharge efficiency is improved.

[0014] According to another aspect, at least one embodiment of the present invention also provides a water conservancy project sewage treatment equipment, wherein the mud pusher plate 2 contacts the surface of the bottom plate 1, the mud pusher plate 1 contacts the surface of the bottom plate 2, the protrusion 1 contacts the protrusion 2, and the mud outlet plate contacts the elastic stop block.

[0015] The adsorption tank includes: an activated carbon filter plate, a connecting block, a connecting rod, a cam, and a second motor. The activated carbon filter plate is fixedly connected to the top of the connecting seat, the connecting block is fixedly connected to the right side of the connecting seat, the connecting rod is rotatably connected to the inside of the connecting block, the second motor is fixedly connected to the bottom of the tank body, the cam is fixedly connected to the output end of the second motor, and the connecting rod is rotatably connected to the surface of the cam.

[0016] For example, in a water conservancy project sewage treatment equipment provided by at least one embodiment of the present invention, the adsorption tank also includes: a gear, a reciprocating screw, a shift rod, and a rack groove. The gear is rotatably connected to the inside of the connecting seat, the reciprocating screw is fixedly connected to the inside of the gear, the shift rod is movably connected to the circumferential surface of the reciprocating screw, and the rack groove is fixedly connected to the inner wall of the tank body.

[0017] When the connecting seat moves back and forth, it drives the activated carbon filter plate to move. The activated carbon filter plate moves to capture the color and odor substances in the filtered sewage. At the same time, the reciprocating movement of the connecting seat drives the gear to move. The gear engages with the rack groove and rotates as it moves. The rotation of the gear drives the reciprocating screw to rotate. The rotation of the reciprocating screw drives the lever to move back and forth. The lever moves the activated carbon powder in the activated carbon filter plate, so that the internal activated carbon particles are always in an active state to enhance the adsorption effect.

[0018] Through the cooperation among the connecting seat, gear, reciprocating screw, lever, activated carbon filter plate, connecting block, connecting rod, cam, rack groove and motor, the internal activated carbon particles are kept in an active state to improve the adsorption effect.

[0019] The gear is engaged with the rack groove, the reciprocating screw is rotatably connected to the bottom of the connecting seat, the cam is rotatably connected to the bottom of the inner wall of the pool body, and the internal space of the activated carbon filter plate is provided with modified activated carbon for specific pollutants such as sulfur modification to remove mercury and iron oxide modification to remove arsenic.

[0020] The surging mechanism includes a transmission rod, a spiral blade, a reciprocating screw, a moving block, a limiting rod, a scraper bar, and a filter plate. The transmission rod is rotatably connected to the inner wall of the pool body, the spiral blade is fixedly connected to the circumferential surface of the transmission rod, the reciprocating screw is fixedly connected to the left end of the transmission rod, the moving block is movably connected to the circumferential surface of the reciprocating screw, the limiting rod is fixedly connected to the right side of the moving block, the scraper bar is fixedly connected to the surface of the moving block, and the filter plate is fixedly installed at the bottom of the pumping assembly. The spiral blade rotates and pushes the sewage inside the pool body, further promoting the contact area between the sewage and the activated carbon filter plate, and improving the adsorption effect of odor in the sewage.

[0021] The scraper bar is in contact with the filter disc, the circumferential surface of the limit rod is slidably connected to the inner wall of the pool body, the circumferential surface of the transmission rod is movably connected to the inner wall of the activated carbon filter plate, and a non-self-locking spiral groove is provided on the surface of the transmission rod. The inner wall of the activated carbon filter plate is provided with a block, and the block is located in the non-self-locking spiral groove. The filter disc can block the sludge and sediment on the left side of the pool body to prevent the sludge and sediment from being pumped to the right side of the pool body by the pumping assembly for deodorization, and the reciprocating movement of the scraper bar can scrape off the sludge and sediment blocked at the bottom of the filter disc to prevent the sludge and sediment from accumulating at the bottom of the filter disc and affecting its subsequent pumping effect.

[0022] The beneficial effects of the embodiments of the present invention are: In the present invention, the coordinated operation among the motor bracket, motor 1, rotating shaft, stirring paddle, medicine outlet box, medicine outlet pipe, baffle and sleeve can be used to intermittently and quantitatively add medicine, which can avoid poor control of medicine dosage during manual dosing. Excessive dosage will lead to excessive concentration of medicine in local areas, making it difficult to diffuse quickly, wasting medicine and increasing cost investment. Insufficient dosage will lead to insufficient flocculation and sedimentation of sewage, affecting the quality of treatment. Multiple small additions will help to gradually disperse, reduce the risk of agglomeration, and improve the mixing quality. At the same time, the stirring paddle can quickly mix the medicine and sewage, thereby improving the purification treatment effect of sewage.

[0023] In the present invention, through the mutual cooperation between connecting rod 1, slide rail 1, slide rail 2, connecting rod 2, protrusion 1, mud discharge plate, protrusion 2, and elastic stop block, the sludge and sediment after the wastewater is drained can be pushed out. Compared with the manual cleaning of sludge and sediment by workers in the prior art, the device can reduce the labor intensity of workers in subsequent cleaning of sludge and sediment. At the same time, the reciprocating swing of the mud discharge plate can prompt the sludge and sediment on its surface to be discharged, preventing the discharged sludge and sediment from staying on the mud discharge plate and affecting the discharge and cleaning effect.

[0024] In the present invention, the activated carbon filter plate can be in contact with the wastewater through the mutual cooperation between the connecting seat, gear, reciprocating screw rod, shift rod, activated carbon filter plate, connecting block, connecting rod, cam, rack groove and motor 2. The odor in many wastewaters comes from harmful chemical substances, such as ammonia nitrogen, hydrogen sulfide, etc. These substances not only produce odor, but also pollute the water body. Activated carbon can adsorb these harmful substances and reduce environmental pollution. At the same time, the activated carbon inside the activated carbon filter plate can be turned over by the reciprocating shift rod, thereby further increasing the contact area between the activated carbon and the wastewater and improving the effect of activated carbon on odor adsorption.

[0025] In the present invention, through the coordinated operation of the transmission rod, spiral blade, reciprocating screw, moving block, limit rod, scraper bar and filter disc, the spiral blade rotates and pushes the sewage inside the pool body, further promoting the contact area between the sewage and the activated carbon filter plate, and improving the adsorption effect of odor in the sewage. At the same time, the filter disc can block the sludge and sediment on the left side of the pool body, preventing the sludge and sediment from being pumped to the right side of the pool body by the pumping assembly for deodorization, and the reciprocating movement of the scraper bar can scrape off the sludge and sediment blocked at the bottom of the filter disc, preventing the sludge and sediment from accumulating at the bottom of the filter disc and affecting its subsequent pumping effect.

Therefore, it should not be understood as a limitation on the present invention.

[0033] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0034] like Figures 1 to 12As shown, it shows a water conservancy project sewage treatment equipment in one embodiment of the present invention, including a tank body 1 and a frame 2, a discharge port 3 is provided on the left side of the tank body 1, a pumping assembly 4 is fixedly connected to the top of the tank body 1, a mud discharge mechanism 6 is provided at the bottom of the inner wall of the tank body 1, an adsorption tank 7 is provided inside the tank body 1, a stirring and dosing mechanism 5 is provided at the bottom of the frame 2, and a surging mechanism 8 is provided inside the tank body 1; the stirring and dosing mechanism 5 includes: a motor bracket 501, a motor 502, a rotating shaft 503, and a stirring paddle 504. The motor bracket 501 is fixedly connected to the top of the frame 2, the motor 502 is fixedly connected to the top of the motor bracket 501, the rotating shaft 503 is fixedly connected to the output end of the motor 502, and the stirring paddle 504 is fixedly connected to the circumferential surface of the rotating shaft 503. The stirring and dosing mechanism 5 also includes: a medicine box 505, a medicine pipe 506, a blocking rod 507, a sleeve 50 8. The medicine outlet box 505 is fixedly installed on the left inner wall of the pool body 1, the medicine outlet pipe 506 is slidably connected to the inside of the medicine outlet box 505, the sleeve 508 is fixedly connected to the inside of the medicine outlet box 505, the baffle 507 is fixedly connected to the circumferential surface of the medicine outlet pipe 506, the medicine outlet pipe 506 is slidably connected to the inner wall of the sleeve 508, and the end of the medicine outlet pipe 506 away from the baffle 507 is fixedly connected with a spring, which can intermittently and quantitatively add medicine, and avoid manual dosing and poor control of the medicine dosage. Excessive dosage causes excessive concentration of medicine in local areas, which makes it difficult to diffuse quickly and wastes medicine, and increases the cost investment. Insufficient dosage causes the sewage to be unable to fully flocculate and precipitate, affecting the treatment quality. Multiple small additions help to gradually disperse, reduce the risk of caking, and improve the mixing quality. At the same time, the stirring paddle 504 can quickly mix the medicine and sewage, thereby improving the sewage purification treatment effect.

[0035] In some examples, after the sewage is discharged into the tank body 1, the motor 502 is started to drive the rotating shaft 503 to rotate, and the rotation of the rotating shaft 503 drives the stirring paddle 504 to rotate, and the stirring paddle 504 stirs the sewage. During the stirring process, the stirring paddle 504 will contact the baffle 507, and the stirring paddle 504 is continuously rotated to push the baffle 507. The baffle 507 moves outward and drives the medicine outlet pipe 506 to move outward to stretch the spring and expose the liquid outlet hole on the medicine outlet pipe 506, so that the medicine can be added intermittently and quantitatively, which can avoid the poor control of the medicine dosage by manual dosing, and the excessive concentration of the medicine in the local area is difficult to quickly Diffusion also wastes chemicals and increases cost investment, while insufficient dosage results in the inability of sewage to fully flocculate and precipitate, affecting the quality of treatment. Multiple small additions help to gradually disperse, reduce the risk of agglomeration, and improve mixing quality. At this time, the flocculant inside the medicine box 505 flows out and is mixed with the sewage by the stirring of the stirring paddle 504. When the stirring paddle 504 moves away from the 507 baffle, the spring resets and drives the 506 medicine outlet pipe to move back. The 506 medicine outlet pipe is retracted to stop discharging medicine. At the same time, the stirring paddle 504 can quickly mix the chemical and sewage, thereby improving the sewage purification treatment effect.

[0036] For example, Figures 1 to 12 As shown, the mud discharge mechanism 6 includes: a mud pushing plate 1 601, a mud pushing plate 2 602, a connecting rod 1 603, a slide rail 1 604, a slide rail 2 605, a connecting rod 2 606, a bottom plate 1 611, a bottom plate 2 612, and a connecting seat 701.

The mud discharge mechanism 6 also includes: a protrusion 607, a mud discharge plate 608, a protrusion 2 609, and an elastic stopper 610. The mud discharge plate 608 is hinged at the bottom of the pool body 1, a protrusion 607 is fixedly connected to the surface of the mud discharge plate 608, a protrusion 2 609 is fixedly connected to the bottom of the connecting rod 2 606, and an elastic stopper 610 is fixedly connected to the inner wall of the frame 2. The mud pusher 602 is in contact with the surface of the bottom plate 1 611, the mud pusher 601 is in contact with the surface of the bottom plate 2 612, and the protrusion 1 607 is in contact with the protrusion 607. Block 2 609 is in contact, and the mud discharge plate 608 is in contact with the elastic stop block 610, which can push the sludge and sediment after the wastewater is drained out. Compared with the workers manually cleaning the sludge and sediment in the existing technology, this device can reduce the labor intensity of the workers when cleaning the sludge and sediment later. At the same time, the reciprocating swing of the mud discharge plate 608 can promote the discharge of the sludge and sediment on its surface, and prevent the discharged sludge and sediment from staying on the mud discharge plate 608 and affecting its discharge and cleaning effect.

[0037] like Figures 1 to 12As shown, it shows another embodiment of the present invention, the adsorption tank 7 includes: an activated carbon filter plate 705, a connecting block 706, a connecting rod 707, a cam 708, and a second motor 710. The activated carbon filter plate 705 is fixedly connected to the top of the connecting seat 701, the connecting block 706 is fixedly connected to the right side of the connecting seat 701, the connecting rod 707 is rotatably connected to the inside of the connecting block 706, the second motor 710 is fixedly connected to the bottom of the tank body 1, the cam 708 is fixedly connected to the output end of the second motor 710, and the connecting rod 707 is rotatably connected to the surface of the cam 708. The adsorption tank 7 also includes: a gear 702, a reciprocating screw rod 703, a shift rod 704, and a rack groove 709. The gear 702 is rotatably connected to the inside of the connecting seat 701, the reciprocating screw rod 703 is fixedly connected to the inside of the gear 702, the shift rod 704 is movably connected to the circumferential surface of the reciprocating screw rod 703, and the rack groove 709 is fixedly connected to the inner wall of the tank body 1. The gear 702 is engaged with the rack groove 709, the reciprocating screw 703 is rotatably connected to the bottom of the connecting seat 701, and the cam 708 is rotatably connected to the bottom of the inner wall of the pool body 1. The internal space of the activated carbon filter plate 705 is provided with modified activated carbon powder for specific pollutants (such as sulfur modification to remove mercury, iron oxide modification to remove arsenic), so that the activated carbon filter plate 705 can come into contact with the wastewater. The odor in many wastewaters comes from harmful chemicals, such as ammonia nitrogen, hydrogen sulfide, etc. These substances not only produce odor, but also pollute the water body. Activated carbon can adsorb these harmful substances and reduce environmental pollution. At the same time, the reciprocating lever 704 can flip the activated carbon inside the activated carbon filter plate 705, further increasing the contact area between the activated carbon and the wastewater, and improving the effect of activated carbon on odor adsorption. In some examples, after the sewage has been fully settled, the pumping assembly 4 pumps the water out to the adsorption tank 7, the motor 2 710 is started to drive the cam 708 to rotate, the rotation of the cam 708 drives the connecting rod 707 to move along the circumferential direction of the cam 708, the movement of the connecting rod 707 drives the connecting block 706 to move, the movement of the connecting block 706 drives the connecting seat 701 to move, the connecting seat 701 is constrained by the slide rail 2 605 and can only do reciprocating motion along the direction of the slide rail 2 605, when the connecting seat 70 When the tank body 1 moves to the left, it will drive the connecting rod 1 603 and the slide rail 1 604 to move to the left. The connecting rod 1 603 pushes the mud pusher 1 601, and the slide rail 1 604 pushes the mud pusher 2 602 to move. The mud pusher 1 601 pushes the precipitated silt from the bottom plate 2 612 to the bottom plate 1 611, and the mud pusher 2 602 pushes the silt from the bottom plate 1 611 to the discharge port 3 for discharge, thereby pushing and discharging the silt and sediment after the wastewater is discharged. Compared with the existing In the conventional technology, workers manually clean up the silt and sediment. The device can reduce the labor intensity of workers in the subsequent cleaning of the silt and sediment. At the same time, when the connecting rod 2 606 moves to the left, the protrusion 2 609 will touch the protrusion 1 607. The continuous movement of the protrusion 2 609 will squeeze the protrusion 1 607. The protrusion 2 609 squeezes the protrusion 1 607 to deflect the mud plate 608 in contact with it downward and compress the elastic stopper 610 in contact with the mud plate 608. The connecting seat 70 When moving back, the mud pushing plate 1 602 pushes the mud pushed down by the mud pushing plate 1 601 to the gap between the bottom plate 1 611 and the bottom plate 2 612 and drops it to the mud discharging plate 608. At the same time, the protrusion 2 609 moves away from the protrusion 1 607, and the mud discharging plate 608 loses its constraint and the elastic stopper 610 returns to its original position. The reciprocating swing of the mud discharging plate 608 can promote the discharge of the mud and sediment on its surface, and prevent the discharged mud and sediment from staying on the mud discharging plate 608 and affecting its discharge and cleaning effect.

[0038] When the connecting seat 701 moves back and forth, it drives the activated carbon filter plate 705 to move, so that the activated carbon filter plate 705 can come into contact with the wastewater. The odor in many wastewaters comes from harmful chemicals, such as ammonia nitrogen, hydrogen sulfide, etc. These substances not only produce odor, but also pollute the water body. Activated carbon can absorb these harmful substances and reduce environmental pollution. At the same time, the reciprocating movement of the connecting seat 701 drives the gear 702 to move, and the gear 702 engages with the rack groove 709 to rotate as it moves. The rotation of the gear 702 drives the reciprocating screw 703 to rotate, and the rotation of the reciprocating screw 703 drives the lever 704 to move back and forth. The lever 704 moves the activated carbon powder in the activated carbon filter plate 705. The reciprocating lever 704 can flip the activated carbon inside the activated carbon filter plate 705, further increasing the contact area between the activated carbon and the wastewater, and improving the effect of the activated carbon on adsorbing odors.

[0039] like Figures 1 to 12As shown, it shows another embodiment of the present invention, the surging mechanism 8 includes a transmission rod 801, a spiral blade 802, a reciprocating screw 803, a moving block 804, a limiting rod 805, a scraper 806, and a filter disc 807. The transmission rod 801 is rotatably connected to the inner wall of the pool body 1, the spiral blade 802 is fixedly connected to the circumferential surface of the transmission rod 801, the reciprocating screw 803 is fixedly connected to the left end of the transmission rod 801, the moving block 804 is movably connected to the circumferential surface of the reciprocating screw 803, the limiting rod 805 is fixedly connected to the right side of the moving block 804, the scraper 806 is fixedly connected to the surface of the moving block 804, and the filter disc 807 is fixedly installed at the bottom of the pumping component 4; the scraper 806 contacts the filter disc 807, the circumferential surface of the limiting rod 805 is slidably connected to the inner wall of the pool body 1, and the transmission rod 80 1 is movably connected to the inner wall of the activated carbon filter plate 705, and a non-self-locking spiral groove is provided on the surface of the transmission rod 801. A card block is provided on the inner wall of the activated carbon filter plate 705, and the card block is located in the non-self-locking spiral groove, so that the spiral blade 802 rotates and pushes the sewage inside the pool body 1, further promoting the contact area between the sewage and the activated carbon filter plate 705, and improving the adsorption effect of odor in the sewage. At the same time, the filter disc 807 can block the sludge and sediment on the left side of the pool body 1 to prevent the sludge and sediment from being pumped to the right side of the pool body 1 by the pumping component 4 for deodorization, and the reciprocating movement of the scraper bar 806 can scrape off the sludge and sediment blocked at the bottom of the filter disc 807 to prevent the sludge and sediment from accumulating at the bottom of the filter disc 807 and affecting its subsequent pumping effect.

[0040] When the activated carbon filter plate 705 moves, it will drive the transmission rod 801 to rotate through the internal block and the non-self-locking spiral groove on the surface of the transmission rod 801. The transmission rod 801 drives the spiral blade 802 to rotate, causing the spiral blade 802 to rotate and push the sewage inside the pool body 1, further promoting the contact area between the sewage and the activated carbon filter plate 705, and improving the adsorption effect of odor in the sewage. At the same time, the filter disc 807 can block the sludge and sediment on the left side of the pool body 1, preventing the sludge and sediment from being pumped to the right side of the pool body 1 by the pumping assembly 4 for deodorization. The rotation of the transmission rod 801 will drive the reciprocating screw 803 to rotate, and the reciprocating screw 803 drives the moving block 804 guided by the limit rod 805 to move back and forth. The moving block 804 drives the scraper 806 to move back and forth. The reciprocating movement of the scraper 806 can scrape off the sludge and sediment blocked at the bottom of the filter disc 807, preventing the sludge and sediment from accumulating at the bottom of the filter disc 807 and affecting its subsequent pumping effect.
