Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to a wastewater treatment apparatus and method based on high-temperature resistant electrode foil for AI servers. Background Technology

[0002] High-temperature resistant electrode foil is a high-performance product developed for high-temperature environment applications in the field of electrode foil. When AI servers process large-scale computing tasks, core components such as GPUs and CPUs generate a lot of heat, causing a significant increase in internal temperature. Traditional electrode foils are prone to performance degradation at high temperatures, such as recrystallization and agglomeration of metal films, resulting in decreased conductivity and increased leakage current, which in turn affects the lifespan and stability of electronic components such as capacitors. Therefore, AI servers need to use high-temperature resistant electrode foil. High-temperature resistant electrode foil must undergo a formation process, which is an indispensable core step in its manufacturing process. The formation process uses electrochemical methods to artificially grow a dense aluminum oxide dielectric layer on the surface of aluminum foil. The quality of this oxide film directly determines the key performance of the electrode foil, especially its high-temperature resistance.

[0003] During the formation of high-temperature resistant electrode foil, electrolyte, unreacted chemicals, and impurities remain on the surface of the electrode foil. To ensure the quality of subsequent processes, the formed foil needs to be rinsed multiple times with a large amount of water to remove surface residues. This generates wastewater. To avoid water pollution caused by direct discharge of wastewater, the wastewater needs to be treated. When treating the wastewater, it is necessary to first filter the wastewater, then adjust the pH of the wastewater, and add flocculants to the wastewater for flocculation.

[0004] Flocculation is a common wastewater treatment method. For example, the wastewater flocculation device disclosed in CN221740009U introduces wastewater and flocculant into a chamber through a feed pipe. The pneumatic motor assembly is then activated, which drives the rotating shaft to rotate. This rotating shaft then drives multiple sets of stirring blades to mix the wastewater and flocculant in the chamber, thereby improving the mixing effect of the flocculant.

[0005] After flocculation and sedimentation, the supernatant needs to be extracted using pumping equipment to achieve solid-liquid separation. However, due to the different impurity content in the wastewater, the volume of the sediment varies. The depth of the pumping pipe needs to be repeatedly adjusted before each operation, which is inconvenient and affects the efficiency of wastewater treatment. At the same time, the strong negative pressure generated during the pumping process can easily cause the sediment in the lower layer of clear liquid to be resuspended, which can easily affect the effect of discharging clear water. Summary of the Invention

[0006] The purpose of this invention is to provide a wastewater treatment device and method based on high-temperature resistant electrode foil for AI servers. This device utilizes a buoyancy block that gradually descends to discharge upper-layer wastewater sequentially from top to bottom, reducing secondary resuspension of sediment. Simultaneously, when the buoyancy block reaches the location of sludge and impurities, the filter holes in the suction pipe block the sludge, preventing further sludge deposition, and the buoyancy block can no longer descend. This ensures sufficient absorption of upper-layer clean water even when there are differences in sediment volume. Compared to existing technologies, this reduces the need for repeated adjustments to the absorption depth, improves wastewater treatment efficiency, and solves the problems mentioned in the background section.

[0010] Preferably, the wastewater treatment device further includes: The scraping assembly, located to the right of the spring, is used to scrape the right side of the suction tube to reduce the clogging of the filter holes by impurities. The scraping assembly includes a rotating rod rotatably connected to the right side of the suction tube. A scraper is fixedly connected to the outer right side of the rotating rod. A rotating frame is arranged on the left side of the rotating rod. A guide slider is fixedly connected to the inner side of the rotating frame. The outer right side of the motion shaft is threaded, and the guide slider moves inside the thread. The right side of the motion shaft extends into the interior of the rotating frame.

[0011] Preferably, the length of the inclined side at the top left side of the buoyancy block is less than the length of the inclined side at the bottom left side of the buoyancy block, and a one-way bearing is installed between the inner side of the rotating frame and the outer side of the rotating rod.

[0012] Preferably, an inlet pipe is inserted into the top of the flocculation box, a motor is fixedly connected to the middle of the top of the flocculation box, the output shaft of the motor passes through the flocculation box and is fixedly connected to the vertical rod, a rotary joint is fixedly installed at the bottom of the vertical rod, a drain pipe is fixedly inserted into the rotary joint, a valve is installed on the part of the drain pipe that passes through the flocculation box, and a stirring blade is fixedly connected to the outer wall of the suction pipe.

[0013] Preferably, the wastewater treatment device further includes: A mixing component is located at the top inner side of the flocculation box. The mixing component is used to mix the coagulant floating on the water surface into the water. The mixing component includes an adsorption tube fixedly connected to the eccentric part inside the buoyancy block. An adsorption frame is fixedly connected to the top of the adsorption tube. A small frame is fixedly connected to the inside of the adsorption tube. A rotating shaft is rotatably connected to the inside of the small frame. Blades are fixedly connected to the outer wall of the rotating shaft. A lifting frame is slidably connected to the top of the outer wall of the rotating shaft.

[0014] Preferably, a piston plate is fixedly connected to the top of the rotating shaft, the outer side of the piston plate is in contact with the inner side of the lifting frame, the interior of the lifting frame above the piston plate is filled with a medium, an elastic rubber membrane is fixedly connected to the top ring side of the lifting frame, and a ball for reducing friction is rotatably connected to the top of the lifting frame.

[0015] Preferably, the bottom of the flocculation box is equipped with a sludge discharge assembly, which includes a long plate fixedly connected to the bottom of the flocculation box, an electric telescopic rod fixedly connected to the bottom of the long plate, and a sealing frame fixedly connected to the output shaft of the electric telescopic rod through the long plate.

[0016] A wastewater treatment method based on high-temperature resistant electrode foil for AI servers. S1, Neutralization: An alkaline solution is added inside the neutralization tank to neutralize the acid in the wastewater; S2. Flocculation: Add flocculant inside the flocculation box to allow impurities to settle.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. Through the action of the drainage component, the buoyancy block will gradually descend under the action of gravity, and squeeze and limit the left end of the movement shaft inside other suction pipes in turn, thereby discharging the upper layer of sewage from top to bottom. This avoids the discharge of clean water from a lower position, which would cause greater disturbance inside the water and reduce the occurrence of secondary suspension of sediment. At the same time, when the buoyancy block moves to the position of sludge and impurities, the filter holes opened in the suction pipe at that time block the sludge and prevent the sludge from moving, and the buoyancy block can no longer descend. This can ensure that enough upper layer of clean water is absorbed even when there are differences in the volume of sediment. Compared with the existing technology, it reduces the process of repeatedly adjusting the absorption depth and improves the efficiency of sewage treatment. 2. The pipes used for discharging sewage in this scheme are stationary and will not disturb the lower layer of sludge, further reducing the possibility of secondary suspension of sediment. Moreover, no external power is required for pumping, reducing energy consumption. 3. The scraping component causes the rotating frame to rotate, which in turn causes the rotating rod to rotate the scraper. The scraper scrapes the filter holes, reducing clogging and improving the efficiency of discharging the upper layer of clean water. 4. The buoyancy block moves downward. Because the inclined side of the bottom left side of the buoyancy block is relatively long, the buoyancy block has to descend a greater distance to allow the moving shaft to move to the right. This makes the rotating frame and rotating rod rotate at a slower speed, reducing the disturbance to the water and further reducing the secondary suspension of sludge. When the moving shaft resets, the scraper does not rotate, further reducing the disturbance to the water. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1: Please refer to Figures 1 to 10This invention provides a technical solution: a wastewater treatment device based on high-temperature resistant electrode foil for AI servers, including an inlet tank 1, a neutralization tank 2 for pH adjustment fixed on the right side of the inlet tank 1, a flocculation tank 3 fixed on the right side of the neutralization tank 2, a first pipe fixedly inserted into the bottom of the inlet tank 1, the first pipe being fixedly inserted into the top of the neutralization tank 2 at a position away from the inlet tank 1, a second pipe fixedly inserted into the bottom of the neutralization tank 2, the second pipe being fixedly inserted into the top of the flocculation tank 3 at a position away from the neutralization tank 2, a water pump for transporting wastewater installed at both the first and second pipes, the water pumps being made of corrosion-resistant materials, an inlet pipe 10 inserted into the top of the flocculation tank 3, a rotary joint 12 fixedly installed at the bottom of the vertical rod 41, the rotary joint 12 being a mature existing technology and not described in detail, a drain pipe 9 fixedly inserted into the rotary joint 12, and a valve 13 installed on the part of the drain pipe 9 that extends out of the flocculation tank 3.

[0023] In use, the wastewater after washing is added into the tank 1, and then the water pump at the first pipe is started, so that the wastewater after filtering impurities enters from the top of the neutralization tank 2. Then, an alkaline solution is added to the neutralization tank 2 to neutralize the acid in the wastewater. The neutralization tank 2 is also equipped with a stirring mechanism for stirring. The structure for stirring is a common existing technology, which will not be described in detail. It is conducive to the thorough mixing of the alkaline solution added inside the neutralization tank 2 with the wastewater. Then, the water pump at the second pipe is started to facilitate the wastewater to enter the flocculation tank 3. At this time, flocculant is added to the flocculation tank 3 through the inlet pipe 10, which is conducive to the sedimentation of impurities in the water.

[0024] The wastewater treatment device also includes a drainage component 4 disposed inside the flocculation tank 3. The drainage component 4 is used to discharge the upper layer of clear water after flocculation and sedimentation while avoiding disturbance to the lower layer of sediment. The drainage component 4 includes a vertical rod 41 disposed inside the flocculation tank 3. A buoyancy block 42 is slidably connected to the outside of the vertical rod 41. A slot 43 is opened on the right side of the buoyancy block 42. A suction pipe 44 is linearly and fixedly inserted into the outer wall of the vertical rod 41 inside the slot 43. A motion shaft 45 is disposed inside the suction pipe 44. The left side of the motion shaft 45 is slidably connected to the vertical rod 41. A sealing plate 46 is fixedly connected to the outer wall of the motion shaft 45. Inside the 4, a retaining ring 47 is fixed to the left of the sealing plate 46. A spring 48 is fixedly connected between the motion shaft 45 and the outer wall of the vertical rod 41. The top and bottom ends of the left side of the buoyancy block 42 are inclined. A filter hole 49 is opened on the right side of the suction pipe 44. A sealing gasket 412 is fixedly connected to the side of the sealing plate 46 near the retaining ring 47. An O-ring seal 411 is installed at the connection between the interior of the vertical rod 41 and the motion shaft 45. The suction pipe 44 is set horizontally. A ball bearing 410 for reducing friction is rotatably connected to the left end of the motion shaft 45. The interior of the buoyancy block 42 is hollow and is made of a high-density metal material.

[0025] By adopting the above technical solution, when the left side of the buoyancy block 42 squeezes and limits the left end of the motion shaft 45, the motion shaft 45 overcomes the elastic force of the spring 48 and moves to the right. At this time, the sealing plate 46 moves to the right and does not block the retaining ring 47. At this time, the inside of the sewage is connected to the inside of the vertical rod 41.

[0026] When the left side of the buoyancy block 42 does not squeeze and limit the left end of the motion shaft 45, the spring force of the spring 48 causes the sealing plate 46 and the sealing gasket 412 on its right side to seal the retaining ring 47. At this time, sewage cannot enter the vertical rod 41 from the suction pipe 44 at this location.

[0027] The external fixed connection of the vertical rod 41 is a limiting strip. During the flocculation stage, the flocculation box 3 needs to be filled with enough water so that the top of the buoyancy block 42 is close to the limiting strip. At this time, the buoyancy block 42 is in a position to squeeze and limit the left end of the motion shaft 45 inside the uppermost suction pipe 44. Since the valve 13 at the drain pipe 9 is closed at this time, the sewage will not be discharged.

[0028] After the flocculant causes impurities to settle, the wastewater inside the flocculation box 3 can be discharged from the drain pipe 9 by opening valve 13 at drain pipe 9. At this time, the buoyancy block 42 is in a position to squeeze and limit the left end of the motion shaft 45 inside the uppermost suction pipe 44, causing the upper layer of clean water to enter the vertical rod 41 from the uppermost suction pipe 44 and be discharged from the drain pipe 9. This will cause the liquid level to drop. As the liquid level drops, under the action of gravity, the buoyancy block 42 will gradually descend, squeezing and limiting the left end of the motion shaft 45 inside the other suction pipes 44 in turn, thereby discharging the upper layer of wastewater from top to bottom. This avoids large internal disturbances caused by discharging clean water from a lower position, reduces the occurrence of secondary suspension of sedimentation, and improves the effect of discharging clean water.

[0029] It should be noted that when the buoyancy block 42 moves downward and gradually discharges the upper layer of clean water, when the buoyancy block 42 moves to the position of sludge and impurities, the filter hole 49 opened in the suction pipe 44 at this point blocks the sludge and prevents the sludge from moving. The buoyancy block 42 can no longer descend. In this way, even when there are differences in the volume of sediment, it can still ensure the absorption of enough upper layer of clean water. Compared with the existing technology, this reduces the process of repeatedly adjusting the absorption depth and improves the efficiency of sewage treatment.

[0030] It should be noted that the pipes used for discharging sewage in this scheme are in a stationary state, which will not disturb the lower layer of sludge, further reducing the possibility of secondary suspension of sediment. In addition, no external power is required for pumping, reducing energy consumption.

[0031] This solution automatically adjusts the height of the drain liquid level, eliminating the need for external power to adjust the drain outlet and reducing energy consumption.

[0032] It should be noted that the suction pipe 44 is arranged horizontally to further reduce disturbance to the water, thereby further reducing the secondary suspension of sediment carried by the lower clear liquid.

[0033] It should be noted that the buoyancy block 42 is made of a metal material with a high density. When the liquid level drops, the gravity of the buoyancy block 42 is sufficient to squeeze and limit the motion shaft 45 and gradually lower it. The buoyancy block 42 has a large volume and is hollow inside, which is sufficient to ensure that it can float smoothly by buoyancy.

[0034] The thickness of the inner side of the buoyancy block 42 is greater than the distance between the two adjacent motion axes 45.

[0035] When wastewater is added into the flocculation box 3, the buoyancy block 42 can gradually rise under the action of buoyancy. During this process, the valve 13 is closed. During this process, when the buoyancy block 42 squeezes the left end of the motion shaft 45, the motion shaft 45 can still move to the right.

[0036] A motor 11 is fixedly connected to the top center of the flocculation box 3. The output shaft of the motor 11 passes through the flocculation box 3 and is fixedly connected to the vertical rod 41. An agitator 8 is fixedly connected to the outer wall of the suction pipe 44.

[0037] It should be noted that the design of the rotary joint 12 ensures that water can be discharged from the drain pipe 9 without affecting the rotation of the vertical rod 41. When the output shaft of the motor 11 rotates, the vertical rod 41 rotates along with the suction pipe 44 and the stirring blade 8, which facilitates the mixing of flocculant and sewage.

[0038] The wastewater treatment device also includes a scraping assembly 5 located to the right of the spring 48, which is used to scrape the right side of the suction pipe 44 to reduce the clogging of the filter holes 49 by impurities. The scraping assembly 5 includes a rotating rod 51 rotatably connected to the right side of the suction pipe 44. A scraper 52 is fixedly connected to the outer right side of the rotating rod 51. A rotating frame 53 is arranged on the left side of the rotating rod 51. A guide slider 54 is fixedly connected to the inner side of the rotating frame 53. A thread 55 is opened on the right side of the outer wall of the motion shaft 45. The guide slider 54 moves inside the thread 55. The right side of the motion shaft 45 extends into the interior of the rotating frame 53.

[0039] By adopting the above technical solution, when the motion shaft 45 is squeezed and limited by the buoyancy block 42, relative motion is generated between the motion shaft 45 and the rotating frame 53. At this time, the guide slider 54 moves inside the thread 55, which can make the rotating frame 53 rotate, thereby making the rotating rod 51 rotate with the scraper 52. In this way, the scraper 52 scrapes the filter hole 49, reducing the clogging of the filter hole 49, thereby improving the efficiency of discharging the upper layer of clean water.

[0040] The length of the inclined side at the top left of the buoyancy block 42 is less than the length of the inclined side at the bottom left of the buoyancy block 42. A one-way bearing 56 is installed between the inner side of the rotating frame 53 and the outer side of the rotating rod 51. The one-way bearing 56 is a mature existing technology and will not be described in detail. It can make the rotating rod 51 not rotate when the rotating frame 53 rotates in one direction.

[0041] By adopting the above technical solution, under the action of the one-way bearing 56, the rotating rod 51 rotates with the rotating frame 53 only when the motion shaft 45 is squeezed and moves to the right. When the motion shaft 45 moves to the left due to the elastic force of the spring 48, the rotating rod 51 does not rotate with the rotating frame 53.

[0042] When draining water, the buoyancy block 42 moves downward. Because the inclined side of the bottom left side of the buoyancy block 42 is relatively long, the buoyancy block 42 needs to descend a greater distance to allow the motion shaft 45 to move to the right. This results in the rotating frame 53 and the rotating rod 51 rotating at a slower speed, reducing disturbance to the water and further reducing the occurrence of secondary suspension of sludge. When the motion shaft 45 resets, the scraper 52 does not rotate, further reducing disturbance to the water.

[0043] When the buoyancy block 42 moves upward, the length of the inclined side at the top left side of the buoyancy block 42 is small, which makes the rotating frame 53 and the rotating rod 51 rotate faster, ensuring the cleaning effect.

[0044] Example 2: The technical solution of this example differs from that of Example 1 in that: Figures 1 to 6 and Figures 11 to 12 The wastewater treatment device also includes a mixing component 6 located at the top inner side of the flocculation tank 3. The mixing component 6 is used to mix the coagulant floating on the water surface into the water. The mixing component 6 includes an adsorption tube 61 fixedly connected to the eccentric part inside the buoyancy block 42. An adsorption frame 62 is fixedly connected to the top of the adsorption tube 61. A small frame 63 is fixedly connected inside the adsorption tube 61. A rotating shaft 64 is rotatably connected inside the small frame 63. A blade 65 is fixedly connected to the outer wall of the rotating shaft 64. The top of the outer wall of the rotating shaft 64 is... The mixing assembly 6 includes a sliding connection of a lifting frame 66 and a transmission ring 68 fixedly connected to the top of the inner side of the flocculation box 3. A ball bearing 610 for reducing friction is rotatably connected to the top of the lifting frame 66. A piston plate 67 is fixedly connected to the top of the rotating shaft 64. The outer side of the piston plate 67 is in contact with the inner side of the lifting frame 66. The interior of the lifting frame 66, located above the piston plate 67, is filled with a medium. An elastic rubber membrane 69 is fixedly connected to the top ring side of the lifting frame 66. The elastic rubber membrane 69 is relatively thick.

[0045] In the initial stage of flocculant addition, some flocculant may float on the surface of the liquid, which will affect the wastewater treatment effect. Therefore, this solution is equipped with a mixing component 6.

[0046] By adopting the above technical solution, since the sewage is placed inside the flocculation box 3, under the action of buoyancy, after the top of the ball 610 is attached to the inner top of the flocculation box 3, under the action of buoyancy, the rotating shaft 64 and the lifting frame 66 generate relative movement, which causes the piston plate 67 to push the medium inside the lifting frame 66. At this time, under the pressure of the medium, the elastic rubber membrane 69 expands, which makes the elastic rubber membrane 69 tightly attached to the inner side of the transmission ring 68, which can generate a large friction force.

[0047] When the output shaft of motor 11 rotates with the stirring blade 8, the buoyancy block 42 rotates with the adsorption tube 61, causing the rotating shaft 64 and the lifting frame 66 to rotate around the axis of motor 11. At this time, under the action of friction between the elastic rubber diaphragm 69 and the transmission ring 68, the rotating shaft 64 causes the blade 65 to rotate around the axis of the rotating shaft 64, which facilitates the adsorption frame 62 to draw the flocculant floating on the liquid surface into the liquid surface. When the blade 65 rotates, it mixes the flocculant, thereby improving the flocculation effect and thus increasing the wastewater treatment rate.

[0048] The bottom of the flocculation box 3 is equipped with a sludge discharge assembly 7. The sludge discharge assembly 7 includes a long plate 71 fixedly connected to the bottom of the flocculation box 3. An electric telescopic rod 72 is fixedly connected to the bottom of the long plate 71. The output shaft of the electric telescopic rod 72 passes through the long plate 71 and is fixedly connected to a sealing frame 73. A sealing material is provided near the flocculation box 3 to ensure the sealing of the flocculation box 3 near the sealing frame 73 when the output shaft of the electric telescopic rod 72 is extended.

[0049] By adopting the above technical solution, after the sewage is extracted, the output shaft of the electric telescopic rod 72 retracts, so that the sealing frame 73 moves away from the flocculation box 3, making it easier to remove the sludge.

[0050] It should be noted that the structure used in this solution is made of corrosion-resistant materials.

[0051] A wastewater treatment method based on high-temperature resistant electrode foil for AI servers. S1. Start the water pump at the first pipeline so that the wastewater after filtering impurities enters from the top of the neutralization tank 2. Then, add an alkaline solution to the neutralization tank 2 to neutralize the acid in the wastewater. S2. Flocculation: By starting the water pump at the second pipeline, the sewage can enter the flocculation tank 3. At this time, flocculant is added to the top of the flocculation tank 3 to facilitate the sedimentation of impurities in the water.

[0052] Working principle: When the left side of the buoyancy block 42 squeezes and limits the left end of the motion shaft 45, the motion shaft 45 moves to the right against the elastic force of the spring 48. At this time, the sealing plate 46 moves to the right as well. The sealing plate 46 does not block the retaining ring 47. At this time, the sewage is connected to the inside of the drain pipe 9. When the left side of the buoyancy block 42 does not squeeze and limit the left end of the motion shaft 45, under the elastic force of the spring 48, the sealing plate 46 and its right sealing gasket 412 seal the retaining ring 47. At this time, the sewage cannot enter the vertical rod 41 from the suction pipe 44. The vertical rod 41 is fixedly connected to the outside of the limiting strip. During the flocculation stage, the flocculation box 3 needs to be filled with enough water so that the top of the buoyancy block 42 is close to the limiting strip. At this time, the buoyancy block 42 is squeezing and limiting the left end of the motion shaft 45 inside the uppermost suction pipe 44. Since the valve 13 at the drain pipe 9 is closed at this time, the sewage will not be discharged.

[0053] After the flocculant causes impurities to settle, the wastewater inside the flocculation box 3 can be discharged from the drain pipe 9 by opening valve 13 at drain pipe 9. At this time, the buoyancy block 42 is in a position to squeeze and limit the left end of the motion shaft 45 inside the uppermost suction pipe 44, causing the upper layer of clean water to enter the vertical rod 41 from the uppermost suction pipe 44 and be discharged from the drain pipe 9. This will cause the liquid level to drop. As the liquid level drops, under the action of gravity, the buoyancy block 42 will gradually descend, squeezing and limiting the left end of the motion shaft 45 inside the other suction pipes 44 in turn, thereby discharging the upper layer of wastewater from top to bottom. This avoids the discharge of clean water from a lower position, which would cause greater disturbance inside the water and reduce the occurrence of secondary suspension of sediment.

[0054] When the motion shaft 45 is squeezed and limited by the buoyancy block 42, relative motion occurs between the motion shaft 45 and the rotating frame 53. At this time, the guide slider 54 moves inside the thread 55, which allows the rotating frame 53 to rotate, thereby causing the rotating rod 51 to rotate with the scraper 52. In this way, the scraper 52 scrapes the filter holes 49, reducing the clogging of the filter holes 49. When draining, the buoyancy block 42 moves downward. Because the inclined side of the bottom left end of the buoyancy block 42 is relatively long, the buoyancy block 42 has to descend a greater distance to allow the motion shaft 45 to move to the right. This makes the rotating frame 53 and the rotating rod 51 rotate at a slower speed, reducing the disturbance to the water and further reducing the secondary suspension of sludge. When the motion shaft 45 is reset, the scraper 52 does not rotate, further reducing the disturbance to the water.

[0055] When the output shaft of motor 11 rotates with stirring blade 8, buoyancy block 42 rotates with adsorption tube 61, causing rotating shaft 64 and lifting frame 66 to rotate around the axis of motor 11. At this time, under the action of friction between elastic rubber membrane 69 and transmission ring 68, rotating shaft 64 with blade 65 rotates around the axis of rotating shaft 64, which facilitates adsorption frame 62 to mix flocculant floating on the liquid surface, thereby improving the flocculation effect.
