Description

Technical Field

[0001] The present invention relates to the technical field of wastewater treatment, and particularly to a wastewater treatment device and method for wastewater containing pigments. Background Technique

[0002] Wastewater treatment aims to remove or reduce harmful substances in wastewater containing pollutants generated in various production and living activities through a series of physical, chemical, and biological methods, so that it meets the discharge standards or can be reused. In the pretreatment stage, large particle impurities are removed through operations such as grids and sedimentation; then, in the chemical treatment link, specific pollutants are treated by methods such as flocculation precipitation and neutralization reaction; in the biological treatment process, organic substances are decomposed by the metabolic activities of microorganisms; in the advanced treatment stage, technologies such as adsorption and membrane separation are used to further purify the water quality. Finally, part of the treated water is discharged up to standard into natural water bodies, and part is reused in fields such as industrial production and urban greening, achieving the dual goals of efficient utilization of water resources and environmental protection.

[0003] When treating wastewater containing pigments, the separation of pigments is usually achieved by adding flocculants. However, in addition to pigments, the wastewater may also contain other substances, such as surfactants. Surfactants may wrap pigment particles, making it difficult for them to come into full contact with flocculants or adsorbents, reducing the flocculation and adsorption efficiency.

[0015] A method for treating wastewater containing pigments, comprising the following steps:

[0016] S1: First, introduce the wastewater into the inner wall of the device through the access port, and the pretreatment unit will intercept larger impurities in the wastewater;

[0017] S2: Then, the wastewater will flow into the flocculation and precipitation unit, and the added flocculant will interact with the pigment particles in the wastewater to coagulate them into larger flocs;

[0018] S3: After flocculation, the waste will flow into the disinfection and adsorption unit to remove residual fine particles and part of the dissolved organic matter, and then be discharged from the device;

[0019] S4: The final cleaning unit will clean the filter plate in the pretreatment unit to facilitate subsequent recycling.

[0020] The beneficial effects of the present invention are as follows:

[0021] 1. By setting up a flocculation and sedimentation unit in the present invention, the air extraction device will extract external air and flow out through the ventilation pipe and the air outlet end. After the air enters the wastewater, a large amount of foam is generated, and the surfactant will be enriched on the surface of the foam. The foam is separated by the mobile phone mechanism, so as to remove part of the surfactant in the wastewater. At the same time, in order to improve the separation effect, an appropriate amount of foaming agent can be added to the sewage, and the ventilation volume and foam height can be controlled.

[0022] 2. By setting up a collection unit in the present invention, the first magnet will attract the second magnet, so that the sliding plate and the collection plate move upward, and the collection plate is aligned with the notch, so as to send the collected foam to the notch. When the moving block stops moving, the inertial effect will cause the foam to flow out, thus realizing the removal of the surfactant.

[0023] 3. By setting up a mechanism for absorbing pigments in the present invention, the buoyancy of the bubbles will cause the fan blades to rotate, which will drive the first support column and the spiral plate to rotate, so that the sewage and the flocculant entering the flocculation pipe are fully mixed. It is also possible to remove the telescopic rod one and pull the overall blocking circular block out of the device through the handle. During this process, the scraping ring will scrape off the pigments adsorbed on the inner wall of the flocculation pipe, avoiding the adhesion of pigments after long-term operation, reducing the cross-sectional area of the pipeline, and reducing the heat transfer efficiency of the equipment.

[0024] 4. By setting up a pretreatment unit in the present invention, the second servo motor will drive the first rotating shaft to rotate, and then drive the second support rod and the filter plate to rotate and move into the cleaning unit. When the filter plate passes through the cleaning mechanism, the scraping plate will first scrape off the dirt on the filter plate, and then the micro motor will drive the second rotating shaft and the hook to rotate to hook impurities such as hair, realizing the cleaning of the filter plate.

[0041] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are given for the purpose of illustration and description, and are not exhaustive or limited to the disclosed form. Many modifications and variations will be obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thus design various embodiments with various modifications suitable for specific purposes.

[0042] Embodiment 1: Use Figures 1 - 14 A wastewater treatment device and treatment method containing pigments according to an embodiment of the present invention will be described as follows.

[0043] As Figures 1 - 2As shown in the figure, a wastewater treatment device containing pigments according to the present invention includes a device housing 1. A base 2 is fixedly connected to the bottom of the device housing 1. An inlet 3 is fixedly connected to the outer surface of the device housing 1. A pretreatment unit 4 is fixedly connected to one end of the device housing 1 near the inlet 3. A flocculation and sedimentation unit 5 is fixedly connected to the inner wall of the device housing 1. An operation console 9 is fixedly connected to the outer surface of the device housing 1. A cleaning unit 6 is fixedly connected to one side of the device housing 1 away from the operation console 9. A disinfection and adsorption unit 7 is fixedly connected to the outer surface of the flocculation and sedimentation unit 5. A top cover 8 is fixedly connected to the top of the device housing 1;

[0044] When the present invention works, first, wastewater is introduced into the inner wall of the device through the inlet 3. Then, the pretreatment unit 4 intercepts larger impurities in the wastewater. At the same time, the cleaning unit 6 cleans the pretreatment unit 4 to ensure the filtering effect. The flocculation and sedimentation unit 5 removes pigment molecules in the sewage. Finally, the disinfection and adsorption unit 7 removes residual fine particles and some dissolved organic matters.

[0045] As Figures 3 - 4 shown, the flocculation and sedimentation unit 5 includes a water storage tank 51. A partition 52 is fixedly connected to the inner wall of the water storage tank 51. A natural sedimentation tank 53 is arranged on the inner wall of the water storage tank 51. A flocculation tank 55 is arranged on the inner wall of the water storage tank 51. A water pump 54 is fixedly connected to the outer surface of the partition 52. Absorbing pigment mechanisms 56 are symmetrically arranged on the inner wall of the flocculation tank 55. A foam separation mechanism 58 is fixedly connected to the bottom of the flocculation tank 55. A collection mechanism 57 is fixedly connected to the top of the flocculation tank 55. A top plate 511 is fixedly connected to one end of the water storage tank 51 near the flocculation tank 55. A dosing device 59 is fixedly connected to the top of the top plate 511. An access pipe 510 is fixedly connected to the outer surface of the dosing device 59;

[0046] As Figure 5 shown, the foam separation mechanism 58 includes an air extraction device 581. An external connection plate 582 is fixedly connected to the outer surface of the air extraction device 581. An air pipe 583 is fixedly connected to one end of the air extraction device 581 away from the external connection plate 582. Air outlet ends 584 are evenly arranged on the outer surface of the air pipe 583.

[0047] The sewage will first enter the natural sedimentation tank 53 for the sedimentation of fine dust. Then, the water pump 54 pumps the sewage into the flocculation tank 55. Then, the air extraction device 581 extracts external air and flows out through the air pipe 583 and the air outlet ends 584. After the air enters the wastewater, a large amount of foam is generated. The surfactant will accumulate on the surface of the foam. The foam is separated through the collection mechanism, thereby removing part of the surfactant in the wastewater. At the same time, in order to improve the separation effect, an appropriate amount of foaming agent can be added to the sewage, and the air flow rate and foam height can be controlled.

[0048] The outer surface of the water storage tank 51 is fixedly connected to the inner wall of the device housing 1, and the outer surface of the air extraction device 581 is fixedly connected to the inner wall of the flocculation tank 55.

[0049] As Figures 8 - 9 shown, the collection mechanism 57 includes a first servo motor 571, which is fixedly connected to the outer surface of the water storage tank 51. The output end of the first servo motor 571 is fixedly connected to a lead screw 572. A moving block 573 is threadedly connected to the outer surface of the lead screw 572. A second support plate 576 is fixedly connected to the outer surface of the moving block 573. A sliding plate 577 is slidably connected to the inner wall of the second support plate 576. A collection plate 578 is fixedly connected to the outer surface of the sliding plate 577. A magnetic block is fixedly connected to the top of the collection plate 578. A first magnetic block 574 is fixedly connected to one end of the water storage tank 51 near the first servo motor 571. A notch 575 is provided on one side of the water storage tank 51 near the first magnetic block 574.

[0050] After the foam adsorbs the surfactant, the first servo motor 571 will drive the lead screw 572 to rotate, thereby controlling the movement of the moving block 573. During this process, the collection plate 578 will collect the foam on the surface of the sewage. At the same time, when the moving block 573 moves to the notch 575, the first magnetic block 574 will attract the second magnetic block 579, so that the sliding plate 577 and the collection plate 578 move upward, and the collection plate 578 is aligned with the notch 575, so as to send the collected foam to the notch 575. When the moving block 573 stops moving, the inertial effect will cause the foam to flow out, thereby realizing the removal of the surfactant.

[0051] As Figures 6 - 7 shown, the pigment absorption mechanism 56 includes a second water pump 561, which is fixedly connected to the inner wall of the water storage tank 51. A first water pipe 562 is fixedly connected to the outer surface of the second water pump 561. A flocculation pipe 563 is fixedly connected to one side of the second water pump 561 away from the first water pipe 562. A first telescopic rod 564 is fixedly connected to the outer surface of the water storage tank 51. The first telescopic rod 564 is detachable. The output end of the first telescopic rod 564 is fixedly connected to a first support plate 565. A pull rod 566 is fixedly connected to the outer surface of the first support plate 565. A blocking round block 567 is fixedly connected to one side of the first support plate 565 away from the pull rod 566. A first support column 568 is rotatably connected to one side of the blocking round block 567 away from the first support plate 565. A fan blade 569 is fixedly connected to one end of the first support column 568 near the blocking round block 567. A first support rod 5610 is fixedly connected to one end of the first support column 568 away from the blocking round block 567. A scraping ring 5611 is fixedly connected to one end of the first support rod 5610. A spiral plate 5612 is fixedly connected to the outer surface of the first support column 568.

[0052] After collecting the surfactant bubbles, the first telescopic rod 564 will extend, causing the first support plate 565 and the barrier circular block 567 to move a certain distance, allowing sewage to enter the flocculation tube 563. Meanwhile, the dosing device 59 will inject the flocculant into the flocculation tube 563 through the connecting pipe 510. The flocculant interacts with the pigment particles in the wastewater, causing them to aggregate into larger flocs, which then precipitate onto the inner wall of the flocculation tube 563 under the action of gravity. During this process, ventilation is continuously carried out, and the buoyancy of the bubbles causes the fan blade 569 to rotate, driving the first support column 568 and the spiral plate 5612 to rotate, ensuring that the sewage and the flocculant entering the flocculation tube 563 are fully mixed. The overall barrier circular block 567 can also be moved out of the device by removing the first telescopic rod 564 and pulling it with the handle. During this process, the scraping ring 5611 will scrape off the pigment adsorbed on the inner wall of the flocculation tube 563, preventing the adhesion of pigment after long-term operation from reducing the cross-sectional area of the pipeline and lowering the heat transfer efficiency of the equipment.

[0053] The specific working process is as follows:

[0054] During operation, first, the sewage will settle fine dust in the natural sedimentation tank 53. Then, the first water pump 54 will pump the sewage into the flocculation tank 55. The air extraction device 581 will extract external air and flow out through the ventilation pipe 583 and the air outlet 584. After the air enters the wastewater, a large amount of foam is generated, removing some surfactants in the wastewater. Then, the collection plate 578 will collect the foam on the surface of the sewage. Finally, the sewage can enter the flocculation tube 563, and at the same time, the dosing device 59 will inject the flocculant into the flocculation tube 563 through the connecting pipe 510. The flocculant interacts with the pigment particles in the wastewater, causing them to aggregate into larger flocs, which then precipitate onto the inner wall of the flocculation tube 563 under the action of gravity.

[0055] Example 2, using Figures 1 - 15 A wastewater treatment device and method for wastewater containing pigments according to an embodiment of the present invention will be described as follows.

[0056] As Figure 10 As shown, in a wastewater treatment device for wastewater containing pigments according to the present invention, on the basis of Example 1, the pretreatment unit 4 includes a separation frame 41. The outer surface of the separation frame 41 is fixedly connected to the inner wall of the device housing 1. The inner wall of the separation frame 41 is fixedly connected with a partition layer 42.

The outer surface of the filter plate 44 is slidably connected with the partition layer 42.

[0057] When the sewage passes through the filter plate 44 and the separation frame 41, larger impurities such as soil and hair will be separated. Long-term operation will cause the filtering effect of the filter plate 44 to deteriorate, or even cause blockage. The second servo motor 45 will drive the first rotating shaft 46 to rotate, and then drive the second support rod 48 and the filter plate 44 to rotate and move into the cleaning unit 6.

[0058] Such as Figure 11 As shown in the figure, the cleaning unit 6 includes an outer frame 61. The outer surface of the outer frame 61 is fixedly connected to the outer surface of the device housing 1. The inner wall of the outer frame 61 is fixedly connected with a second telescopic rod 62. The output end of the second telescopic rod 62 is fixedly connected with a fourth support plate 63. The outer surface of the fourth support plate 63 is fixedly connected with a second support column 64. One end of the second support column 64 away from the fourth support plate 63 is fixedly connected with a cleaning mechanism 65.

[0059] The second telescopic rod 62 will drive the cleaning mechanism 65 to move, so that the cleaning mechanism 65 can come into contact with the rotated filter plate 44.

The output end of the micro motor 654 is fixedly connected with a second rotating shaft 655. The outer surface of the second rotating shaft 655 is fixedly connected with a hook 656.

[0061] For the second telescopic rod 62, when the filter plate 44 passes through the cleaning mechanism 65, the scraping plate will first scrape off the soil on the filter plate 44. Then, the micro motor 654 will drive the second rotating shaft 655 and the hook 656 to rotate, and hook impurities such as hair, so as to clean the filter plate 44.

[0062] Such as Figure 13As shown, the disinfection and adsorption unit 7 includes a first treatment tank 71.

One end of the third water pipe 711 away from the fourth water pump 710 is fixedly connected to the outer surface of the water storage tank 51.

[0063] After the wastewater undergoes flocculation and sedimentation, when it enters the first treatment tank 71, residual fine particles and some dissolved organic matters are further removed through the activated carbon fiber felt 73 and the ion exchange resin 74, and pigment molecules and other organic pollutants in the wastewater are adsorbed, further reducing the chromaticity and organic matter content of the wastewater. At the same time, after the sewage enters the second treatment tank 77, the sewage is disinfected by the ultraviolet device 79 and discharged through the outlet mechanism 78.

[0064] As Figure 14 shown, the outlet mechanism 78 includes a fourth water pipe 781. One end of the fourth water pipe 781 is fixedly connected to the outer surface of the second treatment tank 77.
