[0057] Two first I-shaped wheels are provided and are respectively fixed to the extended end of the first rotating shaft and the output end surface of the servo motor;

[0058] A first belt, drivingly connected between the circumferential surfaces of the two first spools;

[0059] A vertical plate, fixed to the top of the flocculation box and rotatably connected to one end of the first rotating shaft;

[0060] A small I-shaped wheel, fixed on the circumferential surface of the first rotating shaft;

[0061] A large I-shaped wheel fixed to the extended end surface of the transmission shaft;

[0062] The third belt is drivingly connected between the circumferential surfaces of the small I-shaped wheel and the large I-shaped wheel.

[0063] A method for using a vertical mixing device for sewage treatment comprises the following steps:

[0064] S1. First, the sewage is injected from the water inlet pipe into the sewage disinfection tank, and the sewage is filtered through the first filter plate, so that large particles in the sewage are intercepted and roll down from the surface of the first filter plate, and the sewage falls into the sewage disinfection tank, and then disinfectant is added from the disinfectant feed hopper. At this time, the large particles rolling down from the first filter plate enter the collecting bucket from the collecting port, and are intercepted and filtered again by the second filter plate. At the same time, the water flowing into the collecting bucket along the surface of the first filter plate will flow into the bottom of the collecting bucket through the second filter plate, and return to the sewage disinfection tank through the reflux intubation and the reflux fixed pipe;

[0065] S2. At this time, the servo motor in the driving mechanism is started, and the output end of the servo motor drives the driving gear and the second I-shaped wheel to rotate, and the driving gear drives multiple meshing driven gears to rotate, so that the multiple second stirring shafts rotate to achieve longitudinal stirring of the longitudinal stirring rods in the sewage disinfection tank. At the same time, the second I-shaped wheel drives another second I-shaped wheel to drive the worm to rotate through the transmission of the second belt. Since the worm and the worm wheel are meshed, the first stirring shaft rotates to achieve the rotation of multiple transverse stirring rods, so that the transverse stirring rods are transversely stirred in the sewage disinfection tank. At this time, longitudinal and transverse stirring forces are generated in the sewage disinfection tank, which can fully mix the disinfectant and sewage to achieve sewage purification;

[0066] S3. When the sewage purification is completed, the valve is opened to allow the purified sewage to enter the flow box from the outlet pipe for storage. After the sewage disinfection box is empty, the valve is closed and sewage and disinfectant are added to the sewage disinfection box again. Since the servo motor is always started, the process in S1 is repeated in the sewage disinfection box to achieve sewage treatment.

[0067] S4. At this time, the disinfected sewage flowing into the flow box is pumped out by a water pump and introduced into the flocculation box through a water pipe. Then, flocculants are added into the flocculation box, so that the small particles or suspended matter in the sewage in the flocculation box are aggregated into larger flocs, and the sewage in the flocculation box submerges the lowest part of the upper surface of the conveyor belt.

[0068] S5. After the power is transmitted through the transmission mechanism, the power of the output end of the servo motor can drive the first shaft to rotate through the transmission of the first I-shaped wheel and the first belt, and the first shaft drives the roller and the arc block to rotate, so as to intermittently abut against the bottom of one side of the first filter plate, so that one side of the first filter plate reciprocates and bumps, so that the large particles on the surface of the first filter plate can fall into the collection bucket better, and at the same time, the first shaft drives the small I-shaped wheel to rotate, and the small I-shaped wheel, the large I-shaped wheel and the third belt are used to transmit power, so that the transmission shaft rotates, thereby The conveyor belt is driven on the surface of two transmission shafts. At this time, the transmission belt can move multiple J-shaped hooks. Since the flocs flocculated by flocculants in the flocculation box will float on the upper side of the sewage, the flocs can be picked up to the surface of the transmission belt through the J-shaped hook, and transported to the floc collection box through the transmission belt. If the flocs remain in the J-shaped hook, the J-shaped hook will collide with the impact roller when passing through the impact roller, generating vibration, which can shake off the flocs and drop them into the floc collection box for collection, thereby making the sewage in the flocculation box be treated more cleanly and reducing the damage to the environment when discharged.

[0069] Compared with the prior art, the present invention has the following beneficial effects:

[0070] 1. In the present invention, by means of the transverse stirring rod and the longitudinal stirring rod, transverse stirring and longitudinal stirring can be achieved in the sewage disinfection tank, so that the sewage and the disinfectant in the sewage disinfection tank can be better mixed, which can not only effectively improve the sewage treatment efficiency, but also have a better mixing effect.

[0071] 2. In the present invention, the filtering mechanism is provided, so that the treated sewage is not likely to contain large particles, and is not likely to cause blockage to the transmission pipeline, and at the same time, the sewage treatment can be more efficient. At the same time, since one end of the first filter plate in the filtering mechanism is hinged and the other end is intermittently abutted, the first filter plate can reciprocate in an inclined state, and can effectively introduce the large particles filtered out of its surface into the collecting mechanism for collection, and is not likely to block the first filter plate, so that the sewage can be better filtered.

[0072] 3. In the present invention, the collecting mechanism is provided, which can not only collect the filtered particulate matter, but also guide the generated return sewage into the sewage disinfection box for purification, making it difficult for the sewage to be discharged randomly.

[0073] 4. In the present invention, by providing a flow box and a flocculation box, the sewage purified by the disinfectant can be introduced into the flocculation box through the flow box, and can be further filtered by adding flocculants, thereby realizing multiple effective purification treatments of the sewage.

[0074] 5. In the present invention, the cleaning mechanism is provided to make the transmission shaft rotate, so that the transmission belt is driven on the surface of the two transmission shafts. At this time, the transmission belt can move multiple J-shaped hooks. Since the flocs flocculated by the flocculant in the flocculation box will float on the upper side of the sewage, the flocs can be scooped up to the surface of the transmission belt by the J-shaped hook, and transported to the floc collection box through the transmission belt. If the flocs remain in the J-shaped hook, the J-shaped hook will collide with the impact roller when passing through the impact roller, generating vibration, which can shake off the flocs and drop them into the floc collection box for collection, so that the sewage in the flocculation box can be treated more cleanly and the damage to the environment can be reduced when discharged.

[0104] The transmission mechanism is connected with the driving mechanism to realize the transmission of power, so that the filtering mechanism and the cleaning mechanism can operate.

[0105] In a specific embodiment of the present invention, in this device, when sewage enters the sewage disinfection tank 2 through the water inlet pipe 201, large particles are filtered through the filtering mechanism, and the filtered particles are recovered by the collecting mechanism. The first stirring shaft 23 and the second stirring shaft 5 provided in the sewage disinfection tank 2 can respectively drive the horizontal stirring rod 231 and the vertical stirring rod 501 to rotate, so as to achieve simultaneous horizontal and vertical stirring, so that the disinfectant added to the sewage disinfection tank 2 from the disinfectant feed hopper 202 can be fully mixed with the sewage to disinfect and purify the sewage. The disinfected sewage can be transmitted to the flocculation tank 3, and is subjected to secondary treatment by the flocculant. By adding the flocculant, it can be further filtered to achieve multiple effective purification treatments of the sewage. The flocs produced by the flocculant can be cleaned by the cleaning mechanism and collected in the flocculant collecting box 4, which is convenient for the discharge and treatment of the sewage.

[0106] Specifically, the bottom of the sewage disinfection box 2 is fixed with the flow box 1 by four columns. The flow box 1 and the sewage disinfection box 2 are connected by an outlet pipe 203. A valve 204 is provided on the outlet pipe 203. The treated sewage in the sewage disinfection box 2 can be transmitted to the flow box 1 through the outlet pipe 203.

[0107] Specifically, the flocculation box 3 is fixed to the other side of the top of the flow box 1 , and the flow box 1 and the flocculation box 3 are connected through a water pipe 1001 , and a water pump 1002 is provided on the water pipe 1001 .

[0108] In this embodiment: the flocculation box 3 is used to hold the disinfected sewage, and the top is open, and flocculants can be placed to make the small particles or suspended matter in the sewage in the flocculation box 3 gather into larger flocs, which are easy to clean. The water pump 1002 can pump out the sewage in the flow box 1 and discharge it into the flocculation box 3 through the water pipe 1001.

[0109] Specifically, the driving mechanism includes:

[0110] A servo motor 6 is fixed to one side of the flocculation box 3;

[0111] A driving gear 601 is fixed on the circumferential surface of the servo motor 6;

[0112] A plurality of driven gears 502 are provided, which are respectively fixed to the extended end surfaces of the plurality of second stirring shafts 5 and mesh with the driving gears 601;

[0113] The worm 8 is rotatably connected between the inner walls of the sewage disinfection tank 2, and one end of the worm 8 is movable to penetrate the outer side of the sewage disinfection tank 2 and extend;

[0114] The second I-shaped wheels 801 are provided with two and are respectively fixed to the extension end of the worm 8 and the output end of the servo motor 6;

[0115] The second belt 802 is drivingly connected between the circumferential surfaces of the two second I-shaped wheels 801;

[0116] The worm wheel 803 is fixed to the bottom of the circumferential surface of the first stirring shaft 23 , and the worm wheel 803 is meshed with the worm 8 .

[0117] In this embodiment: in the driving mechanism, the servo motor 6 serves as a power output component, driving the driving gear 601 to rotate, which can cause multiple driven gears 502 to rotate, so that the second stirring shaft 5 drives the longitudinal stirring rod 501 to perform longitudinal stirring. At the same time, the output end of the servo motor 6 transmits power through the second I-shaped wheel 801 and the second belt 802, so that the worm 8 rotates, and can drive the first stirring shaft 23 to rotate through the meshing worm gear 803, so that the transverse stirring rod 231 can perform transverse stirring.

[0118] Specifically, the filtering mechanism includes:

[0119] The first bottom plate 704 is fixed to an inner wall of one side of the sewage disinfection tank 2;

[0120] A first spring 705, of which a plurality is provided, one end of each of which is fixed to the top of the first bottom plate 704;

[0121] The first filter plate 7 is arranged on the upper part of the inner wall of the sewage disinfection box 2. One end of the first filter plate 7 is movably hinged to the sewage disinfection box 2, and the other end is located on the upper side of the first bottom plate 704. When the first filter plate 7 is lifted up by the arc block 703, the first spring 705 is stretched. When the arc block 703 is not in contact with the first filter plate 7, the elasticity of the first spring 705 allows the first filter plate 7 to be reset and reciprocatingly shaken.

[0122] A first rotating shaft 701 is rotatably connected to an inner wall of one side of the sewage disinfection tank 2, and one end of the first rotating shaft 701 movably penetrates and extends outside the sewage disinfection tank 2;

At the same time, since one end of the first filter plate 7 in the filtering mechanism is hinged and the other end is intermittently abutted, the first filter plate 7 can reciprocate in an inclined state, and can effectively introduce the larger particles filtered out of its surface into the collecting mechanism for collection, and is not easy to block the first filter plate 7, so that the sewage can be better filtered. When the first filter plate 7 is lifted by the arc block 703, the first spring 705 will be stretched. When the arc block 703 is not in contact with the first filter plate 7, the first filter plate 7 is reset by the elasticity of the first spring 705, and can be reciprocated, so that it is not easy to produce residue on the surface of the first filter plate 7.

[0126] Specifically, a movable groove 709 is opened on one inner wall of the sewage disinfection box 2 , and one end of the first filter plate 7 is located in the movable groove 709 .

[0127] In this embodiment: through the movable groove 709, when the arc block 703 is not in contact with the first filter plate 7, the bottom of the first filter plate 7 is located in the movable groove 709 and abuts against the bottom of the movable groove 709, and does not contact the surface of the roller 702, so that when the roller 702 rotates, it does not contact the first filter plate 7 to generate friction, and does not cause a reduction in service life.

[0128] Specifically, the collection agencies include:

[0129] Two support frames 904 are provided, both of which are fixed to one end of the sewage disinfection tank 2;

[0135] In this embodiment: through the provided collecting mechanism, large particles rolling down from the surface of the first filter plate 7 enter the collecting bucket 9 from the collecting port 905, and are intercepted and filtered again by the second filter plate 901. At the same time, the water flowing into the collecting bucket 9 along the surface of the first filter plate 7 will pass through the second filter plate 901 and flow into the bottom of the collecting bucket 9, and flow back to the sewage disinfection tank 2 through the reflux cannula 902 and the reflux fixed pipe 903. The collecting bucket 9 is placed in two support frames 904, and the reflux cannula 902 is inserted into the reflux fixed pipe 903, so that the collecting bucket 9 is easy to disassemble and the large particles collected in the collecting bucket 9 are easy to handle. The upper part of the support frame 904 is in an "L" shape, and the bottom is sealed, and a space for accommodating the collecting bucket 9 is formed with the end of the sewage disinfection tank 2. The edges on both sides of the bottom of the collecting bucket 9 are flat, which can be better placed on the support frame 904.

[0140] A transmission belt 12 is drivingly connected between the circumferential surfaces of the two transmission shafts 11;

[0141] A plurality of J-shaped hooks 13 are provided and are all fixed to the circumferential surface of the transmission belt 12;

[0142] The second bottom plate 15 is fixed between the adjacent ends of the two support plates 14;

[0143] A second spring 16, of which a plurality of springs are provided, and one end of each of the plurality of second springs 16 is fixed to the top of the second bottom plate 15;

[0144] A connecting plate 17, fixed to the other end of the plurality of second springs 16;

[0145] Two connecting blocks 18 are provided and are fixed to both sides of the top of the connecting plate 17 respectively;

[0146] The impact roller 19 is rotatably connected between the adjacent ends of the two connection blocks 18 , and the impact roller 19 abuts against the J-shaped hook 13 intermittently.

[0147] In this embodiment: when flocs are produced in the flocculation box 3, the transmission mechanism is used to rotate the transmission shaft 11, so that the transmission belt 12 is transmitted on the surface of the two transmission shafts 11. At this time, the transmission belt 12 can move multiple J-shaped hooks 13. Since the flocs flocculated by the flocculant in the flocculation box 3 will float on the upper side of the sewage, the flocs can be scooped up to the surface of the transmission belt 12 by the J-shaped hook 13, and transported to the floc collection box 4 through the transmission belt 12. If the flocs remain in the J-shaped hook 13, the J-shaped hook 13 will collide with the impact roller 19 when passing through the impact roller 19, generating vibration, which can shake off the flocs and drop them into the floc collection box 4 for collection, so that the sewage in the flocculation box 3 can be treated more cleanly and the damage to the environment can be reduced when discharged. The impact roller 19 is elastically supported by the second spring 16 The property makes it that when the impact roller 19 contacts the J-shaped hook 13, there will be no rigid connection, and the J-shaped hook 13 can be better collided, so that the flocs in the J-shaped hook 13 can fall into the floc collecting box 4. The transmission belt 12 is arranged in an inclined state at the middle and upper part of the flocculation box 3, and a part of it extends into the floc collecting box 4. Since the transmission belt 12 is inclined and the flocs are wet, they can be smoothly transmitted to the floc collecting box 4 through the surface of the transmission belt 12. The flocs in the flocculation box 3 drive the J-shaped hook 13 to move under the rotation of the transmission belt 12. The movement of the J-shaped hook 13 causes the sewage to generate inertia and move to the lower side of the transmission belt 12. At the same time, the shape of the J-shaped hook 13 can pick up the flocs, so that the flocs can be better salvaged. Preferably, the J-shaped hook 13 can be provided with small protrusions to facilitate better salvaging of the flocs.

[0148] Specifically, the transmission mechanism includes:

[0149] Two first I-shaped wheels 706 are provided and are respectively fixed to the extended end of the first rotating shaft 701 and the output end surface of the servo motor 6;

[0150] A first belt 707 is drivingly connected between the circumferential surfaces of the two first I-shaped wheels 706;

[0151] The vertical plate 708 is fixed to the top of the flocculation box 3 and is rotatably connected to one end of the first rotating shaft 701;

[0152] The small I-shaped wheel 20 is fixed on the circumferential surface of the first rotating shaft 701;

[0153] A large I-shaped wheel 21 is fixed to the extended end surface of the transmission shaft 11;

[0154] The third belt 22 is drivingly connected between the circumferential surfaces of the small I-shaped wheel 20 and the large I-shaped wheel 21 .

[0155] In this embodiment: the first I-shaped pulley 706 and the first belt 707 can realize power transmission, and transmit the power of the output end of the servo motor 6 to the first rotating shaft 701, so that the first rotating shaft 701 rotates, and the small I-shaped pulley 20, the large I-shaped pulley 21 and the third belt 22 can transmit the power of the first rotating shaft 701 to the transmission shaft 11. At the same time, due to the different diameters of the small I-shaped pulley 20 and the large I-shaped pulley 21, the transmission ratio is different, so that when the small I-shaped pulley 20 rotates, the third belt 22 rotates slowly after the power is transmitted by the third belt 22, so that the transmission shaft 11 drives the transmission belt 12 to rotate slowly, and it is not easy to cause the transmission belt 12 to rotate too fast and throw the flocs out.

[0156] It should be noted that the servo motor 6 and the water pump 1002 are both existing technologies, and corresponding models can be selected according to actual needs, and no further details will be given for this.

[0157] Example 2

[0158] This embodiment 2 provides a method for using a vertical mixing device for sewage treatment, which is used to further explain and illustrate the working principle and method for using a vertical mixing device for sewage treatment provided in the above embodiment 1, as follows:

[0159] A method for using a vertical mixing device for sewage treatment comprises the following steps:

[0160] S1. First, the sewage is injected into the sewage disinfection tank 2 from the water inlet pipe 201, and the sewage is filtered through the first filter plate 7, so that large particles in the sewage are intercepted and roll down from the surface of the first filter plate 7, and the sewage falls into the sewage disinfection tank 2, and then disinfectant is added from the disinfectant feed hopper 202. At this time, the large particles rolling down from the first filter plate 7 enter the collecting bucket 9 from the collecting port 905, and are intercepted and filtered again by the second filter plate 901. At the same time, the water flowing into the collecting bucket 9 along the surface of the first filter plate 7 will pass through the second filter plate 901 and flow into the bottom of the collecting bucket 9, and flow back to the sewage disinfection tank 2 through the reflux intubation 902 and the reflux fixed pipe 903;

[0161] S2. At this time, the servo motor 6 in the driving mechanism is started, and the output end of the servo motor 6 drives the driving gear 601 and the second I-shaped wheel 801 to rotate, and the driving gear 601 drives the multiple meshing driven gears 502 to rotate, so that the multiple second stirring shafts 5 rotate, so as to realize the longitudinal stirring rods 501 to perform longitudinal stirring in the sewage disinfection tank 2, and at the same time, the second I-shaped wheel 801 drives another second I-shaped wheel 801 to drive the worm 8 to rotate through the transmission of the second belt 802. Since the worm 8 and the worm wheel 803 are meshed, the first stirring shaft 23 rotates to realize the rotation of multiple transverse stirring rods 231, so that the transverse stirring rods 231 are transversely stirred in the sewage disinfection tank 2. At this time, longitudinal and transverse stirring forces are generated in the sewage disinfection tank 2, which can make the disinfectant and sewage fully mixed, so as to achieve the purification of sewage;

[0162] S3. When the sewage purification is completed, the valve 204 is opened to allow the purified sewage to enter the flow box 1 from the outlet pipe 203 for storage. After the sewage disinfection box 2 is empty, the valve 204 is closed, and sewage and disinfectant are added to the sewage disinfection box 2 again. Since the servo motor 6 is always started, the process in S1 is repeated in the sewage disinfection box 2 to achieve sewage treatment.

[0163] S4, the disinfected sewage flowing into the flow box 1 is pumped out by the water pump 1002, and introduced into the flocculation box 3 through the water pipe 1001, and then a flocculant is added into the flocculation box 3, so that the small particles or suspended matter in the sewage in the flocculation box 3 are aggregated into larger flocs, and the sewage in the flocculation box 3 submerges the lowest part of the upper surface of the transmission belt 12;

[0164] S5. After the power is transmitted through the transmission mechanism, the power of the output end of the servo motor 6 can drive the first rotating shaft 701 to rotate through the transmission of the first I-shaped wheel 706 and the first belt 707. The first rotating shaft 701 drives the roller 702 and the arc block 703 to rotate, so as to intermittently abut against the bottom of one side of the first filter plate 7, so that one side of the first filter plate 7 reciprocates and bumps, so that the large particles on the surface of the first filter plate 7 can better fall into the collecting bucket 9. At the same time, the first rotating shaft 701 drives the small I-shaped wheel 20 to rotate, and the small I-shaped wheel 20, the large I-shaped wheel 21 and the third belt 22 are used to transmit power, so that the transmission shaft 11 rotates. Thereby, the transmission belt 12 is driven on the surface of the two transmission shafts 11. At this time, the transmission belt 12 can move multiple J-shaped hooks 13. Since the flocs flocculated by the flocculant in the flocculation box 3 will float on the upper side of the sewage, the flocs can be scooped up to the surface of the transmission belt 12 through the J-shaped hook 13, and transported to the floc collection box 4 through the transmission belt 12. If the flocs remain in the J-shaped hook 13, the J-shaped hook 13 will collide with the impact roller 19 when passing through the impact roller 19, generating vibration, which can shake off the flocs and drop them into the floc collection box 4 for collection, so that the sewage in the flocculation box 3 can be treated more cleanly and the damage to the environment can be reduced when discharged.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.

First, sewage is injected from the water inlet pipe (201) into the sewage disinfection tank (2), and the sewage is filtered through the first filter plate (7) so that large particles in the sewage are intercepted and roll down from the surface of the first filter plate (7), and the sewage falls into the sewage disinfection tank (2). Then, disinfectant is added from the disinfectant feed hopper (202). At this time, the large particles rolling down from the first filter plate (7) enter the collection bucket (9) from the collection port (905), and are intercepted and filtered again by the second filter plate (901). At the same time, the water flowing into the collection bucket (9) along the surface of the first filter plate (7) will pass through the second filter plate (901) and flow into the bottom of the collection bucket (9), and flow back to the sewage disinfection tank (2) through the reflux intubation tube (902) and the reflux fixed pipe (903); S2, at this time, the servo motor (6) in the driving mechanism is started, and the output end of the servo motor (6) drives the driving gear (601) and the second I-shaped wheel (801) to rotate, and the driving gear (601) drives the plurality of meshing driven gears (502) to rotate, thereby causing the plurality of second stirring shafts (5) to rotate, so that the longitudinal stirring rods (501) can perform longitudinal stirring in the sewage disinfection tank (2), and at the same time, the second I-shaped wheel (801) drives another second I-shaped wheel (801) to drive the worm (8) to rotate through the second belt (802), and since the worm (8) and the worm wheel (803) are meshed, the first stirring shaft (23) can rotate, so that the plurality of transverse stirring rods (231) can rotate, so that the transverse stirring rods (231) can stir transversely in the sewage disinfection tank (2), and at this time, longitudinal and transverse stirring forces are generated in the sewage disinfection tank (2), so that the disinfectant and the sewage can be fully mixed, thereby achieving sewage purification; S3. When the sewage purification is completed, the valve (204) is opened to allow the purified sewage to enter the flow box (1) from the outlet pipe (203) for storage. After the sewage disinfection box (2) is empty, the valve (204) is closed and sewage and disinfectant are added to the sewage disinfection box (2) again. Since the servo motor (6) is always started, the process in S1 is repeated in the sewage disinfection box (2) to achieve sewage treatment. S4, the disinfected sewage flowing into the flow box (1) is pumped out by the water pump (1002), and introduced into the flocculation box (3) through the water pipe (1001), and then a flocculant is added into the flocculation box (3), so that the small particles or suspended matter in the sewage in the flocculation box (3) are aggregated into larger flocs, and the sewage in the flocculation box (3) submerges the lowest part of the upper surface of the transmission belt (12); S5.

The first rotating shaft (701) drives the rotating roller (702) and the arc block (703) to rotate, so as to intermittently abut against the bottom of one side of the first filter plate (7), so that one side of the first filter plate (7) reciprocates and bumps, so that large particles on the surface of the first filter plate (7) can fall into the collecting bucket (9) better.

The conveyor belt (12) is moved so that the conveyor belt (12) is driven on the surfaces of the two conveyor shafts (11). At this time, the conveyor belt (12) can move the plurality of J-shaped hooks (13). Since the flocs flocculated by the flocculant in the flocculation box (3) float on the upper side of the sewage, the flocs can be scooped up to the surface of the conveyor belt (12) by the J-shaped hooks (13) and transported to the floc collection box (4) through the transmission of the conveyor belt (12). If the flocs remain in the J-shaped hooks (13), the J-shaped hooks (13) will collide with the impact roller (19) when passing through the impact roller (19), generating vibration, which can shake the flocs off and drop them into the floc collection box (4) for collection, thereby making the sewage in the flocculation box (3) be treated more cleanly and reducing the damage to the environment when discharged.
