Description

Technical Field

[0001] The present invention relates to the technical field of sewage purification and treatment, and particularly relates to a hierarchical treatment type sewage purification and treatment device. Background Art

[0002] Sewage refers to water that has been polluted, whose physical, chemical, and biological properties have changed, containing various pollutants, making it no longer suitable for its original use. The pollutants in sewage include organic matter, inorganic matter, microorganisms, and other components. The presence of these components will have an adverse impact on the water environment, ecosystem, and human health. The pollutants in sewage will cause direct or indirect harm to aquatic organisms. Heavy metal ions, toxic organic substances, etc. will directly poison aquatic organisms and cause their death. Sewage contains various microorganisms, including bacteria, viruses, fungi, and protozoa.

[0003] When performing hierarchical treatment on sewage, it is first necessary to perform pretreatment work on the sewage. However, when performing pretreatment work on the sewage, when intercepting some solid debris, when the sewage passes through, the impurities in the sewage easily clog the mesh holes on the mesh plate, thereby interfering with the filtration work of the pretreatment. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the technical solution adopted by the present invention to solve its technical problems is: A hierarchical treatment type sewage purification and treatment device of the present invention includes: A pretreatment component, which is used to purify the impurities in the sewage. A feeding component is fixedly connected to the side of the pretreatment component, and a precipitation component is fixedly connected to the side of the feeding component away from the pretreatment component; The pretreatment component includes a connecting pipe. A mesh plate is fixedly connected to the inner side of the connecting pipe. A connecting shaft is slidably connected to the side of the mesh plate. One end of the connecting shaft away from the mesh plate is fixedly connected to a connecting frame. A first spring is sleeved on the connecting shaft. One end of the first spring is fixedly connected to the connecting frame, and the other end of the first spring is fixedly connected to the mesh plate. A cleaning mechanism is fixedly connected to the side of the connecting frame close to the mesh plate, and the cleaning mechanism is concentrically arranged with the mesh holes of the mesh plate; After the sewage pipe is connected to one end of the connecting pipe, as sewage continuously enters the connecting pipe, the impurities in the sewage are blocked by the mesh plate. At the same time, as sewage continuously enters the connecting pipe, due to the impact force of the sewage, the connecting frame moves away from the mesh plate through the connecting shaft; Preferably, the cleaning mechanism includes a cleaning rod. One end of the cleaning rod away from the mesh plate is fixedly connected to a connecting frame. A notch is formed on the side surface of the cleaning rod. A slider is slidably connected to the inner side of the notch. A connecting rod is fixedly connected to the side surface of the slider. The side surface of the connecting rod is slidably connected to the inner side of the cleaning rod. One end of the connecting rod away from the slider is fixedly connected to a cleaning block. A fourth spring is sleeved on the connecting rod. One end of the fourth spring is fixedly connected to the cleaning block, and the other end of the fourth spring is fixedly connected to the cleaning rod. When the mesh plate filters sewage, after the impurities in the sewage clog the mesh plate and the impact force of the sewage passing through the mesh plate is less than the tensile force of the first spring, the connecting frame is driven by the tensile force of the first spring, so that the connecting frame drives the cleaning rod to move towards the mesh holes of the mesh plate, and then the cleaning rod drives the cleaning block to move towards the mesh holes of the mesh plate to eject the impurities blocking the mesh holes of the mesh plate. At the same time, when the cleaning block extrudes and ejects the impurities in the mesh holes of the mesh plate, when the extrusion force between the cleaning block and the impurities blocking the mesh holes of the mesh plate is greater than the tensile force of the fourth spring, the cleaning block drives the connecting rod to slide inside the notch through the slider, and at the same time, through the buffering work of the fourth spring, it is avoided that the extrusion force between the cleaning block and the impurities blocking the mesh holes of the mesh plate is too large, which may cause extrusion damage to the cleaning block and may cause frictional damage to the aperture of the mesh holes of the mesh plate, and further cause the phenomenon of the expansion of the mesh holes of the mesh plate. Preferably, the feeding component includes a feeding housing. The side surface of the feeding housing is fixedly connected to a connecting pipe. A support one is fixedly connected to the inner side of the feeding housing. A rotating blade is rotatably connected to the side surface of the support one. One side of the rotating blade away from the support one is rotatably connected to a support two. The side surface of the support two is fixedly connected to the inner side of the feeding housing. The side surface of the feeding housing is fixedly connected to a feeding box. The top of the feeding box is fixedly connected to a feeding port. An extrusion mechanism is fixedly connected in the feeding box. Preferably, the extrusion mechanism includes an extrusion shaft, the side surface of the extrusion shaft is slidably connected to the inner sides of the feeding housing and the feeding box, the bottom of the extrusion shaft is fixedly connected with an extrusion plate, the top of the extrusion shaft is fixedly connected with a connecting plate, a second spring is sleeved on the extrusion shaft, the top of the second spring is fixedly connected with the bottom of the connecting plate, and the bottom of the second spring is fixedly connected with the bottom of the inner cavity of the feeding box. Both sides of the bottom of the connecting plate are fixedly connected with sliding rods, the bottom of the sliding rods is fixedly connected with a material blocking plate, the side surface of the material blocking plate is slidably connected to the inner side of the feeding box, the bottom of the material blocking plate is fixedly connected with a material blocking block, and the side surface of the material blocking block is slidably connected to the inner side of the feeding housing; Flocculant is added into the feeding box through the feed port. When the sewage enters the feeding housing through the connecting pipe, due to the impact force of the sewage passing through the feeding housing, the sewage drives the rotating blade to rotate inside the feeding housing. Then, according to the passing speed of the sewage, the rotating blade rotates inside the feeding housing, so that the rotating blade squeezes the extrusion plate. When the extrusion plate receives the squeezing force, the extrusion plate drives the connecting plate to move upward inside the feeding housing through the extrusion shaft. At the same time, the connecting plate drives the material blocking plate and the material blocking block to move upward through the sliding rods, so that the flocculant in the feeding box enters the feeding housing through the gap generated between the material blocking block and the feeding housing. Furthermore, according to the speed of the sewage passing through, the impact speed of the rotating blade on the extrusion plate in the feeding housing can be used to add an appropriate amount of flocculant to the sewage; Preferably, the precipitation component includes a precipitation tank, the precipitation tank is fixedly connected to the side of the feeding housing away from the connecting pipe, a gate valve is fixedly connected to the inner side of the precipitation tank, a check valve is fixedly connected to the side of the precipitation tank away from the gate valve, a fixing frame one is fixedly connected to the inner side of the precipitation tank, an impact mechanism is rotatably connected to the side of the fixing frame one away from the check valve, and a fixing frame two is rotatably connected to the side of the impact mechanism away from the fixing frame one. The side surface of the fixing frame two is fixedly connected to the inner side of the precipitation tank; When the sewage mixed with the flocculant enters the precipitation tank through the check valve, the impact of the sewage drives the impact mechanism to rotate in the precipitation tank, so as to carry out an impact operation on the sewage mixed with the flocculant, so that the flocculant can fully react with the sewage. At the same time, the sewage can be discharged into the sedimentation tank by opening the gate valve, so as to carry out the subsequent sedimentation treatment work; Preferably, the impact mechanism includes an impact plate. A sliding rod is slidably connected to the inner side of the impact plate. One end of the sliding rod away from the impact plate is fixedly connected to a scraper. A third spring is sleeved on the sliding rod. One end of the third spring is fixedly connected to the scraper, and the other end of the third spring is slidably connected to the inner side of the impact plate. A collection assembly is fixedly connected to the side of the impact plate. Due to the impact of sewage, the impact plate rotates inside the sedimentation tank. At the same time, due to the action of centrifugal force, the scraper slides out inside the impact plate through the sliding rod, so that the scraper fully impacts the sewage mixed with the medicament. At the same time, by contacting and rotating with the inner wall of the sedimentation tank, the flocculent impurities attached to the inner wall of the sedimentation tank are scraped off. At the same time, when the impact plate rotates, the collection assembly can collect the impurities in the sedimentation tank. Preferably, the collection assembly includes a collection box. The side of the collection box is fixedly connected to the impact plate. A baffle is fixedly connected to the inner side of the collection box. A rotating plate is rotatably connected to the side of the collection box. Arc-shaped rods are rotatably connected to both sides of the rotating plate. A sliding groove is formed on the side of the arc-shaped rod. Shafts are fixedly connected to both sides of the collection box. The side of the shaft is slidably connected to the inner side of the sliding groove. A spring rod is fixedly connected to the side of the shaft, and the other end of the spring rod is fixedly connected to the inner side of the sliding groove. When the impact plate rotates due to the impact force of sewage, the collection box is driven to rotate at the same time. When the scraper fully impacts the sewage mixed with the flocculant medicament, when the collection box rotates accordingly, the larger flocs formed by the reaction of sewage and flocculant drugs can be brought into the collection box. At the same time, when the collection box rotates, due to the impact force of sewage entering the inner side of the collection box and the circular holes evenly formed on the side of the collection box, the rotating plate rotates on the shaft through the arc-shaped rod, so that the flocs in the sewage enter the collection box through the gap generated by the rotating plate for collection work. At the same time, when the impact plate stops rotating, the arc-shaped rod moves back on the shaft through the sliding groove on the side due to the reset work of the spring rod, so as to drive the rotating plate to reset and block, thus preventing the flocs in the collection box from slipping out.

[0005] The beneficial effects of the present invention are as follows: 1. By setting the pretreatment component in the present invention, after one end of the sewage pipe is connected to the connecting pipe, as sewage continuously enters the connecting pipe, the net plate blocks the impurities in the sewage. At the same time, as sewage continuously enters the connecting pipe, due to the impact force of the sewage, the connecting frame moves away from the net plate side through the connecting shaft.

[0006] 2. By providing a cleaning mechanism in the present invention, when the mesh plate filters sewage, after impurities in the sewage clog the mesh plate and the impact force of the sewage passing through the mesh plate is less than the tensile force of the first spring, the connecting frame is driven by the tensile force of the first spring, so that the connecting frame drives the cleaning rod to move towards the mesh holes of the mesh plate, and then the cleaning rod drives the cleaning block to move towards the mesh holes of the mesh plate, ejecting the impurities blocking the mesh holes of the mesh plate.

[0007] 3. By providing a feeding component in the present invention, a flocculating agent is added into the feeding tank through the feeding port. When the sewage enters the feeding outer shell through the connecting pipe, due to the impact force of the sewage passing through the feeding outer shell, the sewage drives the rotating blade to rotate inside the feeding outer shell. Then, according to the passing speed of the sewage, the rotating blade rotates inside the feeding outer shell, so that the rotating blade squeezes the extrusion plate. When the extrusion plate is subjected to the squeezing force, the extrusion plate drives the connecting plate to move upward inside the feeding outer shell through the extrusion shaft. At the same time, the connecting plate drives the blocking plate and the blocking block to move upward through the sliding rod, so that the flocculating agent in the feeding tank enters the feeding outer shell through the gap generated between the blocking block and the feeding outer shell. Thus, an appropriate amount of flocculating agent can be added to the sewage according to the impact speed of the rotating blade on the extrusion plate in the feeding outer shell due to the passing speed of the sewage.

[0008] 4. By providing an impact mechanism in the present invention, due to the impact of the sewage, the impact plate rotates inside the sedimentation tank. At the same time, due to the action of centrifugal force, the scraping plate slides out inside the impact plate through the sliding rod. Then, the scraping plate fully impacts the sewage with the mixed agent. At the same time, by contacting and rotating with the inner wall of the sedimentation tank, the flocculating impurities attached to the inner wall of the sedimentation tank are scraped off. At the same time, when the impact plate rotates, the impurity collection component can collect the impurities in the sedimentation tank. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Embodiment 1, using Figures 1 - 4 A hierarchical treatment type sewage purification treatment device according to an embodiment of the present invention is described as follows; As Figures 1 - 4 shown, a hierarchical treatment type sewage purification treatment device of the present invention includes: A pretreatment component 1, which is used for purifying impurities in sewage. A feeding component 2 is fixedly connected to the side of the pretreatment component 1, and a precipitation component 3 is fixedly connected to the side of the feeding component 2 away from the pretreatment component 1; The pretreatment component 1 includes a connecting pipe 11. A net plate 12 is fixedly connected to the inner side of the connecting pipe 11. A connecting shaft 13 is slidably connected to the side surface of the net plate 12. One end of the connecting shaft 13 away from the net plate 12 is fixedly connected to a connecting frame 15. A first spring 14 is sleeved on the connecting shaft 13. One end of the first spring 14 is fixedly connected to the connecting frame 15, and the other end of the first spring 14 is fixedly connected to the net plate 12. A cleaning mechanism 16 is fixedly connected to the side of the connecting frame 15 close to the net plate 12. The cleaning mechanism 16 is concentrically arranged with the mesh holes of the net plate 12. After the sewage pipe is connected to one end of the connecting pipe 11, as sewage continuously enters the connecting pipe 11, the net plate 12 blocks impurities in the sewage. At the same time, as sewage continuously enters the connecting pipe 11, due to the impact force of the sewage, the connecting frame 15 moves away from the net plate 12 through the connecting shaft 13. The cleaning mechanism 16 includes a cleaning rod 161. One end of the cleaning rod 161 away from the net plate 12 is fixedly connected to the connecting frame 15. A notch 162 is formed on the side surface of the cleaning rod 161. A slider 163 is slidably connected to the inner side of the notch 162. A connecting rod 164 is fixedly connected to the side surface of the slider 163. The side surface of the connecting rod 164 is slidably connected to the inner side of the cleaning rod 161. One end of the connecting rod 164 away from the slider 163 is fixedly connected to a cleaning block 165. A fourth spring 166 is sleeved on the connecting rod 164. One end of the fourth spring 166 is fixedly connected to the cleaning block 165, and the other end of the fourth spring 166 is fixedly connected to the cleaning rod 161. When the net plate 12 filters sewage, when impurities in the sewage block the net plate 12 and the impact force of the sewage on the net plate 12 is less than the tensile force of the first spring 14, the connecting frame 15 is driven by the tensile force of the first spring 14, so that the connecting frame 15 drives the cleaning rod 161 to move towards the mesh holes of the net plate 12, and then the cleaning rod 161 drives the cleaning block 165 to move towards the mesh holes of the net plate 12 to eject the impurities blocking the mesh holes of the net plate 12. At the same time, when the cleaning block 165 extrudes and ejects the impurities in the mesh holes of the net plate 12, when the extrusion force between the cleaning block 165 and the impurities blocking the mesh holes of the net plate 12 is greater than the tensile force of the fourth spring 166, the cleaning block 165 drives the connecting rod 164 to slide inside the notch 162 through the slider 163. At the same time, through the buffering of the fourth spring 166, it is avoided that the extrusion force between the cleaning block 165 and the impurities blocking the mesh holes of the net plate 12 is too large, which may cause extrusion damage to the cleaning block 165 and frictional damage to the aperture of the mesh holes of the net plate 12, resulting in the phenomenon of the expansion of the mesh holes of the net plate 12. Example 2, usage Figures 5 - 6 The following description is made for a hierarchical treatment type sewage purification treatment device of the present invention; As Figures 5 - 6 shown, a hierarchical treatment type sewage purification treatment device of the present invention is based on Example 1; The feeding component 2 includes a feeding outer shell 21. The side surface of the feeding outer shell 21 is fixedly connected to the connecting pipe 11. Inside the feeding outer shell 21, a first support 22 is fixedly connected. A rotating blade 24 is rotatably connected to the side surface of the first support 22. On the side of the rotating blade 24 away from the first support 22, a second support 23 is rotatably connected. The side surface of the second support 23 is fixedly connected to the inside of the feeding outer shell 21. A feeding box 25 is fixedly connected to the side surface of the feeding outer shell 21. At the top of the feeding box 25, a feeding port 26 is fixedly connected. An extrusion mechanism 27 is fixedly connected in the feeding box 25; The extrusion mechanism 27 includes an extrusion shaft 271. The side surface of the extrusion shaft 271 is slidably connected to the inside of the feeding outer shell 21 and the feeding box 25. At the bottom of the extrusion shaft 271, an extrusion plate 272 is fixedly connected. At the top of the extrusion shaft 271, a connecting plate 273 is fixedly connected. A second spring 274 is sleeved on the extrusion shaft 271. The top of the second spring 274 is fixedly connected to the bottom of the connecting plate 273. The bottom of the second spring 274 is fixedly connected to the bottom of the inner cavity of the feeding box 25. On both sides of the bottom of the connecting plate 273, sliding rods 275 are fixedly connected. At the bottom of the sliding rods 275, a material blocking plate 276 is fixedly connected. The side surface of the material blocking plate 276 is slidably connected to the inside of the feeding box 25. At the bottom of the material blocking plate 276, a material blocking block 277 is fixedly connected. The side surface of the material blocking block 277 is slidably connected to the inside of the feeding outer shell 21; By adding a flocculant into the feeding box 25 through the feeding port 26, when the sewage enters the feeding outer shell 21 through the connecting pipe 11, due to the impact force of the sewage passing through the feeding outer shell 21, the sewage drives the rotating blade 24 to rotate inside the feeding outer shell 21. Then, according to the passing speed of the sewage, the rotating blade 24 rotates inside the feeding outer shell 21, so that the rotating blade 24 squeezes the extrusion plate 272. When the extrusion plate 272 is subjected to the squeezing force, the extrusion plate 272 drives the connecting plate 273 to move upward inside the feeding outer shell 21 through the extrusion shaft 271. At the same time, the connecting plate 273 drives the material blocking plate 276 and the material blocking block 277 to move upward through the sliding rods 275, so that the flocculant in the feeding box 25 enters the feeding outer shell 21 through the gap generated between the material blocking block 277 and the feeding outer shell 21. Thus, an appropriate amount of flocculant can be added to the sewage according to the speed of the sewage passing through and the impact speed of the rotating blade 24 on the extrusion plate 272 in the feeding outer shell 21; Example 3, usage Figures 7 - 9 The following is an explanation of a hierarchical treatment type sewage purification treatment device of the present invention; As Figures 7 - 9 shown, a hierarchical treatment type sewage purification treatment device of the present invention, on the basis of Example 1; The precipitation component 3 includes a precipitation tank 31. The precipitation tank 31 is fixedly connected to the side of the feeding housing 21 away from the connecting pipe 11. A gate valve 32 is fixedly connected to the inside of the precipitation tank 31. A one-way valve 33 is fixedly connected to the side of the precipitation tank 31 away from the gate valve 32. A first fixing frame 34 is fixedly connected to the inside of the precipitation tank 31. An impact mechanism 36 is rotatably connected to the side of the first fixing frame 34 away from the one-way valve 33. A second fixing frame 35 is rotatably connected to the side of the impact mechanism 36 away from the first fixing frame 34. The side of the second fixing frame 35 is fixedly connected to the inside of the precipitation tank 31. When the sewage mixed with the flocculant enters the precipitation tank 31 through the one-way valve 33, the impact of the sewage drives the impact mechanism 36 to rotate in the precipitation tank 31, so as to impact the sewage mixed with the flocculant, so that the flocculant can fully react with the sewage. At the same time, the sewage can be discharged into the sedimentation tank by opening the gate valve 32 for subsequent precipitation treatment work; The impact mechanism 36 includes an impact plate 361. A sliding rod 362 is slidably connected to the inside of the impact plate 361. A scraping plate 363 is fixedly connected to the end of the sliding rod 362 away from the impact plate 361. A third spring 364 is sleeved on the sliding rod 362. One end of the third spring 364 is fixedly connected to the scraping plate 363. The other end of the third spring 364 is slidably connected to the inside of the impact plate 361. A collection component 365 is fixedly connected to the side of the impact plate 361. Due to the impact of the sewage, the impact plate 361 rotates inside the precipitation tank 31. At the same time, due to the action of centrifugal force, the scraping plate 363 slides out inside the impact plate 361 through the sliding rod 362, so that the scraping plate 363 fully impacts the sewage mixed with the medicine. At the same time, by contacting and rotating the inner wall of the precipitation tank 31 through the scraping plate 363, the flocculant impurities attached to the inner wall of the precipitation tank 31 are scraped off. At the same time, when the impact plate 361 rotates, the collection component 365 can collect the impurities in the precipitation tank 31; The collection component 365 includes a collection box 3651. The side of the collection box 3651 is fixedly connected to the impact plate 361. A baffle 3652 is fixedly connected to the inner side of the collection box 3651. A rotating plate 3653 is rotatably connected to the side of the collection box 3651. Arc-shaped rods 3655 are rotatably connected to both sides of the rotating plate 3653. A sliding groove 3656 is formed on the side of the arc-shaped rod 3655. Rotating shafts 3654 are fixedly connected to both sides of the collection box 3651. The side of the rotating shaft 3654 is slidably connected to the inner side of the sliding groove 3656. A spring rod 3657 is fixedly connected to the side of the rotating shaft 3654. The other end of the spring rod 3657 is fixedly connected to the inner side of the sliding groove 3656. When the impact plate 361 rotates by the impact force of the sewage, it simultaneously drives the collection box 3651 to rotate. Thus, when the scraper 363 fully impacts the sewage mixed with the flocculant agent, while the collection box 3651 rotates accordingly, it can bring the larger flocs formed by the reaction of the sewage and the flocculant drug into the collection box 3651. At the same time, when the collection box 3651 rotates, due to the impact force of the sewage entering the inner side of the collection box 3651, and through the uniformly arranged round holes on the side of the collection box 3651, the rotating plate 3653 rotates on the rotating shaft 3654 through the arc-shaped rod 3655. Thus, the flocs in the sewage enter the collection box 3651 through the gap generated by the rotating plate 3653 for collection work. At the same time, when the impact plate 361 stops rotating, the arc-shaped rod 3655 performs a reset movement on the rotating shaft 3654 through the reset work of the spring rod 3657, thereby driving the rotating plate 3653 to perform a reset blocking work, thus avoiding the phenomenon that the flocs in the collection box 3651 slide out. The specific working process is as follows: During operation, one end of the sewage pipe is connected to the pretreatment component 1 to perform pretreatment filtration on the sewage in the sewage pipe. The sewage passing through the pretreatment component 1 enters the feeding component 2 to perform drug feeding on the sewage. At the same time, due to the continuous flow of the sewage, the sewage with the added drug enters the precipitation component 3 to accelerate the reaction time between the impurities and the drug in the sewage. After the sewage pipe is connected to one end of the connecting pipe 11, as the sewage continuously enters the connecting pipe 11, the net plate 12 blocks the impurities in the sewage. At the same time, as the sewage continuously enters the connecting pipe 11, due to the impact force of the sewage, the connecting frame 15 moves away from the net plate 12 through the connecting shaft 13. When the wire mesh plate 12 filters sewage, when the impurities in the sewage clog the wire mesh plate 12, and the impact force of the sewage passing through the wire mesh plate 12 is less than the tensile force of the first spring 14, the connecting frame 15 is driven by the tensile force of the first spring 14, so that the connecting frame 15 drives the cleaning rod 161 to move towards the mesh holes of the wire mesh plate 12. Thus, the cleaning rod 161 drives the cleaning block 165 to move towards the mesh holes of the wire mesh plate 12, ejecting the impurities blocking the mesh holes of the wire mesh plate 12. At the same time, when the cleaning block 165 squeezes and ejects the impurities in the mesh holes of the wire mesh plate 12, when the extrusion force between the cleaning block 165 and the impurities blocking the mesh holes of the wire mesh plate 12 is greater than the tensile force of the fourth spring 166, the cleaning block 165 drives the connecting rod 164 to slide inside the notch 162 through the slider 163. At the same time, through the buffering work of the fourth spring 166, it is possible to avoid excessive extrusion force between the cleaning block 165 and the impurities blocking the mesh holes of the wire mesh plate 12, which may cause extrusion damage to the cleaning block 165 and frictional damage to the aperture of the mesh holes of the wire mesh plate 12, and further cause the phenomenon of the expansion of the mesh holes of the wire mesh plate 12; Add flocculant into the feeding box 25 through the feeding port 26. When the sewage enters the feeding outer shell 21 through the connecting pipe 11, due to the impact force of the sewage passing through the feeding outer shell 21, the sewage drives the rotating blade 24 to rotate inside the feeding outer shell 21. Then, according to the speed of the sewage passing through, the rotating blade 24 rotates inside the feeding outer shell 21, so that the rotating blade 24 squeezes the extrusion plate 272. When the extrusion plate 272 is subjected to the extrusion force, the extrusion plate 272 drives the connecting plate 273 to move upward inside the feeding outer shell 21 through the extrusion shaft 271. At the same time, the connecting plate 273 drives the blanking plate 276 and the blanking block 277 to move upward through the sliding rod 275, so that the flocculant in the feeding box 25 enters the feeding outer shell 21 through the gap generated by the blanking block 277 and the feeding outer shell 21. Thus, it is possible to add an appropriate amount of flocculant to the sewage according to the impact speed of the rotating blade 24 on the extrusion plate 272 in the feeding outer shell 21 according to the speed of the sewage passing through; When the sewage mixed with the flocculant enters the sedimentation tank 31 through the one-way valve 33, the impact mechanism 36 is driven to rotate in the sedimentation tank 31 by the impact of the sewage, so as to impact the sewage mixed with the flocculant. Thus, the flocculant can fully react with the sewage. At the same time, the sewage can be discharged into the sedimentation pond by opening the gate valve 32 for subsequent sedimentation treatment; Through the impact of sewage, the impact plate 361 rotates inside the sedimentation tank 31. Meanwhile, under the action of centrifugal force, the scraping plate 363 slides out inside the impact plate 361 through the sliding rod 362. Furthermore, the scraping plate 363 fully impacts the sewage with the mixed medicament. At the same time, by contacting and rotating with the inner wall of the sedimentation tank 31, the flocculent impurities attached to the inner wall of the sedimentation tank 31 are scraped off. Meanwhile, when the impact plate 361 rotates, the collection assembly 365 can collect the impurities in the sedimentation tank 31; When the impact plate 361 rotates due to the impact force of sewage, it drives the collection box 3651 to rotate simultaneously. Thus, when the scraping plate 363 fully impacts the sewage with the mixed flocculent medicament, while the collection box 3651 rotates accordingly, the larger flocs formed by the reaction of sewage and flocculent drugs can be brought into the collection box 3651. At the same time, when the collection box 3651 rotates, due to the impact force of sewage entering the inside of the collection box 3651, and since circular holes are evenly formed on the side surface of the collection box 3651, the rotating plate 3653 rotates on the rotating shaft 3654 through the arc rod 3655. Thus, the flocs in the sewage enter the collection box 3651 through the notch generated by the rotating plate 3653 for collection work. Meanwhile, when the impact plate 361 stops rotating, the arc rod 3655 moves back on the rotating shaft 3654 through the side sliding groove 3656 due to the reset work of the spring rod 3657, thereby driving the rotating plate 3653 to perform a reset and blocking operation, thus preventing the flocs in the collection box 3651 from sliding out.
