[0002] Micro-electrolysis-Fenton coupling is a wastewater treatment method that combines micro-electrolysis and Fenton oxidation. It is particularly suitable for treating wastewater containing high concentrations of difficult-to-degrade organic matter, such as phosphating wastewater.

[0003] When using the micro-electrolysis-Fenton coupling treatment method to treat phosphating wastewater, it is first necessary to use the iron-carbon microbattery principle to form a large number of primary cells in the phosphating wastewater, generate new substances through electrochemical reactions, and then carry out Fenton oxidation reaction by adding hydrogen peroxide. After the Fenton oxidation is completed, the wastewater is treated to make the suspended matter and other substances in the wastewater condense into flocs and precipitate, thereby completing the entire treatment operation.

[0004] However, during long-term use and observation, it was found that the existing micro-electrolysis Fenton coupling device for phosphating wastewater required the discharge of the clearer liquid on the top after sedimentation was completed. When the upper liquid was about to be discharged, the sediment at the bottom would be affected by the water flow and move, and thus would be discharged together with the upper liquid, affecting the treatment effect.

[0005] To this end, the utility model provides a new micro-electrolysis Fenton coupling equipment for phosphating wastewater. Utility Model Content

After a period of sedimentation, the sludge and other sediments will sink to the bottom of the first partition plate 12. At this time, the liquid above the first partition plate 12 is a relatively clear liquid. After the sedimentation is completed, the first motor 15 is started to drive the screw 16 to rotate, thereby driving the bracket 18 to move upward, so that the multiple fixed blocks 19 move up and the multiple drop grooves 13 are blocked, so that the upper and lower parts of the first partition plate 12 are separated. At this time, the clear liquid above the first partition plate 12 is pumped out, which can reduce the occurrence of sediment being discharged along with the clear liquid. Through the above structure, the sediment can be separated from the clear liquid after the sedimentation is completed, so that when the clear liquid is discharged, the sediment can be reduced from mixing into the clear liquid and being discharged, thereby reducing the impact on the phosphating wastewater treatment effect.

[0025] like Figures 1 to 4 As shown, the side wall of the sedimentation tank 1 is fixedly connected to multiple second motors 2; the output end of the second motor 2 is rotatably connected to an auger 21; multiple fixed pipes 22 are fixedly connected to the side of the sedimentation tank 1 away from the multiple second motors 2; the interior of the fixed pipes 22 is fixedly connected to a fixed plate 23; the other end of the auger 21 is rotatably connected to the middle of the fixed plate 23; the side wall of the sedimentation tank 1 is fixedly connected to a collecting tank 24; the collecting tank 24 is located below the multiple fixed pipes 22; when working, before use, the multiple fixed pipes 22 are plugged with a plug. Block it, and then discharge the phosphating wastewater into the sedimentation tank 1 for sedimentation. After the sedimentation is completed and the clear liquid above the first partition plate 12 is discharged, the plug is removed to release the blockage of the fixed pipe 22, and then the multiple second motors 2 are started to drive the multiple screw dragons 21 to rotate, so that the sediment and wastewater below the first partition plate 12 are discharged through the multiple fixed pipes 22 and fall into the collection tank 24. Through the above structure, the sediment at the bottom of the sedimentation tank 1 can be conveniently cleaned and collected, thereby facilitating subsequent treatment of the sediment.

[0026] like Figures 1 to 4As shown, the middle of the fixed pipe 22 is fixedly connected to the filter plate 3; the middle of the fixed pipe 22 is provided with a first drop opening 31; the first drop opening 31 is located below between the auger 21 and the filter plate 3; the middle of the fixed pipe 22 is rotatably connected to a sleeve 32; the middle of the sleeve 32 is provided with a second drop opening 33; the middle of the collecting tank 24 is fixedly connected to a second partition plate 34; during sedimentation, the sleeve 32 is rotated to stagger the first drop opening 31 and the second drop opening 33 to prevent wastewater from flowing out through the first drop opening 31, and the sedimentation tank is filled with wastewater by the rotation of the auger 21. When the internal sediment is discharged through the fixed pipe 22, the sediment and wastewater will first be sent between the auger 21 and the filter plate 3 by the auger 21, and the liquid therein will flow out through the filter plate 3 and fall to one side of the second partition plate 34, while the sediment will remain in the fixed pipe 22. After the liquid separation is completed, the sleeve 32 is rotated to overlap the first drop opening 31 and the second drop opening 33, so that the sediment inside the fixed pipe 22 falls to the other side of the second partition plate 34 through the first drop opening 31, thereby completing the separation of the sediment and the liquid, and facilitating subsequent reprocessing.

[0027] like Figure 1 As shown, the side wall of the sedimentation tank 1 is fixedly connected to a third motor 4; the output end of the third motor 4 is fixedly connected to a first gear 41; the middle part of the sleeve 32 is fixedly connected to a second gear 42; the side wall of the sedimentation tank 1 is rotatably connected to multiple third gears 43; the first gear 41 is engaged with one of the second gears 42; multiple second gears 42 and multiple third gears 43 are engaged with each other; when multiple sleeves 32 need to be rotated, the third motor 4 is started to drive the first gear 41 to rotate, so that the multiple sleeves 32 are rotated at the same time through the cooperation between the first gear 41, the second gear 42, and the third gear 43. Through the above structure, the positions of the multiple second blanking ports 33 can be conveniently adjusted, thereby facilitating the adjustment of the positional relationship between the multiple second blanking ports 33 and the first blanking port 31.

[0028] like Figures 1 to 4 As shown, a scraper 5 is fixedly connected to the end of the auger 21; the other end of the scraper 5 is arranged in contact with the side wall of the filter plate 3; during operation, when the sediment is discharged through the first discharge port 31, the rotation of the auger 21 drives the scraper 5 to rotate, and the sediment remaining on the inner wall of the fixed tube 22 can be scraped off, and the sediment attached to the side wall of the filter plate 3 can be scraped off. Through the above structure, when the sediment is discharged, the residual sediment inside the fixed tube 22 can be reduced, and the discharge of the sediment can be more thorough.

[0029] like Figure 2As shown, the drop chute 13 is arranged in a stepped shape; the upper opening area of the drop chute 13 is larger than the bottom opening area; through the above structure, the plane area of the top of the first partition plate 12 can be reduced, thereby reducing the sediment remaining above the first partition plate 12. At the same time, the reduction in the bottom area of the first partition plate 12 can make the size of the fixed block 19 correspondingly reduced, reducing the sediment remaining above the fixed block 19, and then reducing the sediment remaining above the first partition plate 12 after the precipitated wastewater is separated.

[0030] like Figure 2 As shown, the fixed block 19 is arranged in a stepped manner; the top area of the fixed block 19 is smaller than the bottom area; through the above structure, the residual sediment above the fixed block 19 can be further reduced, and when the fixed block 19 rises, the water flow is used to wash away the sediment in the middle of the fixed block 19, thereby further reducing the residual sediment above the first partition plate 12 after the wastewater after precipitation is separated.

[0031] During operation, the treated phosphating wastewater is discharged into the sedimentation tank 1 for sedimentation. After a period of sedimentation, sludge and other sediments will sink to the bottom of the first partition plate 12. At this time, the liquid above the first partition plate 12 is a relatively clear liquid. After the sedimentation is completed, the first motor 15 is started to drive the screw 16 to rotate, thereby driving the bracket 18 to move upward, so that the multiple fixed blocks 19 move upward and the multiple drop grooves 13 are blocked, so that the upper and lower parts of the first partition plate 12 are separated. At this time, the clear liquid above the first partition plate 12 is pumped out, which can reduce The sediment is discharged along with the clear liquid. Before use, the multiple fixed pipes 22 are blocked with plugs, and then the phosphating wastewater is discharged into the sedimentation tank 1 for sedimentation. After the sedimentation is completed and the clear liquid above the first partition plate 12 is discharged, the plugs are removed to release the blockage of the fixed pipes 22, and then the multiple second motors 2 are started to drive the multiple screw dragons 21 to rotate, so that the sediment and wastewater below the first partition plate 12 are discharged through the multiple fixed pipes 22 and fall into the interior of the collection tank 24. During the sedimentation, the sleeve 32 is rotated to make the first drop The feed port 31 is staggered with the second feed port 33 to prevent wastewater from flowing out through the first feed port 31. When the sediment inside the sedimentation tank 1 is discharged through the fixed pipe 22 by the rotation of the auger 21, the sediment and wastewater will first be sent by the auger 21 between the auger 21 and the filter plate 3, and the liquid therein will flow out through the filter plate 3 and fall to one side of the second partition plate 34, while the sediment will remain inside the fixed pipe 22. After the liquid separation is completed, the sleeve 32 is rotated to make the first feed port 31 overlap with the second feed port 33, so that the liquid inside the fixed pipe 22 The sediment falls to the other side of the second partition plate 34 through the first drop port 31. When it is necessary to rotate multiple sleeves 32, the third motor 4 is started to drive the first gear 41 to rotate, so that the multiple sleeves 32 are rotated at the same time through the cooperation between the first gear 41, the second gear 42, and the third gear 43. When the sediment is discharged through the first drop port 31, the rotation of the auger 21 drives the scraper 5 to rotate, which can scrape off the sediment remaining on the inner wall of the fixed tube 22 and the sediment attached to the side wall of the filter plate 3.
