Description

Technical Field

[0001] This utility model relates to the field of high-concentration organic wastewater treatment technology, specifically to a device for treating high-concentration organic wastewater by combining electrochemical catalytic oxidation. Background Technology

[0002] With rapid industrial development, the discharge of high-concentration organic wastewater is increasing year by year. This type of wastewater typically contains recalcitrant organic matter, high COD (chemical oxygen demand), and toxic and harmful substances. Direct discharge without effective treatment will cause serious harm to the ecological environment and human health. Traditional wastewater treatment methods, such as biological treatment and chemical oxidation, suffer from low treatment efficiency, high operating costs, and the potential for secondary pollution, making them unsuitable for treating high-concentration organic wastewater. Electrochemical catalytic oxidation technology, due to its high efficiency, environmental friendliness, and ease of operation, shows promising application prospects in the treatment of high-concentration organic wastewater. This technology effectively degrades organic matter, even achieving complete mineralization, through redox reactions on the electrode surface. However, existing electrochemical catalytic oxidation devices for treating high-concentration organic wastewater suffer from uneven wastewater flow within the reactor, resulting in insufficient contact with the electrodes. Furthermore, the lack of a flexible adjustment mechanism makes it difficult to adapt to different water qualities and flow rates.

[0003] Announcement No. CN221565879U discloses an apparatus for treating high-concentration organic wastewater using a combination of electrochemical catalytic oxidation. The apparatus includes: a circulation pipe A fixedly connected to the left surface of a pretreatment tank; a conveying pipe A fixedly connected to the right surface of the pretreatment tank; an electrolysis tank fixedly connected to the end of the conveying pipe A furthest from the pretreatment tank; a circulation pipe B fixedly connected to the right surface of the electrolysis tank; a conveying pipe B fixedly connected to the right surface of the electrolysis tank; a secondary treatment tank fixedly connected to the end of the conveying pipe B furthest from the electrolysis tank; and a conveying pipe C fixedly connected to the left surface of the secondary treatment tank. This apparatus enables multiple cycles of wastewater treatment in each process, facilitating precise control of the wastewater treatment process and achieving optimal treatment results.

[0004] Regarding the aforementioned prior art, the inventors believe that the following shortcomings exist: the device for treating high-concentration organic wastewater by combining electrochemical catalytic oxidation can achieve multiple cycles in each process of wastewater treatment, which is beneficial for precise control of the wastewater treatment process and achieving the best treatment effect. However, although this device achieves wastewater circulation through multi-stage tanks and circulation pipes, it does not optimize the water flow distribution inside the reactor, which may lead to insufficient contact between wastewater and electrodes, affecting reaction efficiency and making it impossible to flexibly adjust the treatment parameters according to changes in wastewater flow or water quality. Utility Model Content

[0005] The purpose of this invention is to provide a device for treating high-concentration organic wastewater using electrochemical catalytic oxidation, in order to solve the problem mentioned in the background art. While this device can achieve multiple cycles in each process of wastewater treatment, which is beneficial for precise control of the wastewater treatment process and achieving the best treatment effect, although it achieves wastewater circulation through multi-stage tanks and circulation pipes, it does not optimize the water flow distribution inside the reactor, which may lead to insufficient contact between wastewater and electrodes, affecting reaction efficiency and making it impossible to flexibly adjust treatment parameters according to changes in wastewater flow or water quality.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a device for treating high-concentration organic wastewater by electrochemical catalytic oxidation, including a reactor body: the inner cavity of the reactor body is fixedly provided with an adjustment structure, and the inner cavity of the reactor body is fixedly provided with an aeration structure. The adjustment structure includes a fixed plate 1, a cylinder, a telescopic shaft, a fixed plate 2, a sliding rail, a sliding block, and a guide plate; The first fixing plate is fixedly connected to the outer wall of the reactor body, the cylinder is fixedly connected to one side of the first fixing plate, the telescopic shaft is slidably connected to the inner cavity of the cylinder, the second fixing plate is fixedly connected to the lower side of the telescopic shaft, the sliding track is fixedly connected to the lower side of the second fixing plate, the sliding block is slidably engaged with the lower side of the sliding track, and the guide plate is fixedly installed on the lower side of the sliding block.

[0007] Furthermore, the cylinder is connected to the second fixed plate via a telescopic shaft, the second fixed plate is connected to the second sliding plate via a sliding rail and a sliding block, a plurality of sliding blocks are provided on the lower side of the sliding rail, a plurality of guide plates are provided on the lower side of the sliding rail, and the guide plates are connected to the sliding rail via the sliding blocks.

[0008] Furthermore, the adjustment structure also includes a sliding column, an adjustment plate body, and a sliding groove; The sliding column is fixedly connected to one side of the guide plate, the main body of the adjusting plate is slidably connected to one side of the sliding column, and the sliding groove is opened in the inner cavity of the main body of the adjusting plate.

[0009] Furthermore, the regulating plate body is fixedly installed on the inner wall of the reactor body, the reactor body is connected by a sliding column and a guide plate, and multiple sliding slots are provided on the regulating plate body.

[0010] Furthermore, a top plate is fixedly installed on the upper side of the reactor body, and three slots are opened on the top plate, with the telescopic column slidably connected to the slots.

[0011] Furthermore, the aeration structure includes an external air source, an aeration pipe, and a microporous aeration head; The external air source is fixedly connected to the outer wall of the reactor body, the aeration pipe is arranged in a grid pattern at the bottom of the reactor body, and the microporous aeration heads are evenly distributed on the aeration pipe.

[0012] Furthermore, the aeration pipe is connected to an external air source, the microporous aeration head is made of a flexible polymer material, and the surface of the microporous aeration head is covered with an anti-fouling coating.

[0013] This utility model has the following beneficial effects: I. This utility model incorporates an adjustment structure. This structure, driven by a cylinder, moves a telescopic shaft up and down, causing the fixed plate and sliding track to move synchronously. A sliding block slides on the sliding track, allowing the guide plates to adjust their position and angle according to wastewater treatment requirements, thereby optimizing the wastewater flow path and reaction efficiency. A sliding column is fixed to one side of the guide plate and engages with a sliding groove on the main body of the adjustment plate. This allows the guide plates to adjust the spacing between them according to the shape of the sliding groove, resulting in greater stability during movement. The slots on the top plate slide against the telescopic column, ensuring smooth and airtight movement of the column while protecting the internal structure and preventing external impurities from entering the reactor. The adjustment structure allows for adjustment of the spacing between the guide plates, accommodating wastewater treatment at different flow rates.

[0014] II. Based on the aforementioned beneficial effects, an aeration structure is also incorporated. This structure supplies gas via an external gas source, which is then transported through aeration pipes to microporous aeration heads, forming tiny bubbles that are evenly distributed throughout the wastewater. By optimizing the pore size and spacing of the microporous aeration heads, the gas-liquid contact area is maximized, improving oxygen transfer efficiency and thus enhancing the electrochemical catalytic oxidation reaction. The introduction of gas into the reactor body via aeration creates a gas stirring effect. As the gas rises, it drives the wastewater flow, achieving mixing and mass transfer. This method not only promotes contact between organic matter and the electrodes but also washes away contaminants from the electrode surface, reducing pollutant deposition and improving electrode stability and lifespan.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0020] Please see Figure 1-4 As shown, this utility model is a device for treating high-concentration organic wastewater by electrochemical catalytic oxidation, including a reactor body 1: the inner cavity of the reactor body 1 is fixedly provided with an adjustment structure 2, and the inner cavity of the reactor body 1 is fixedly provided with an aeration structure 3. The adjustment structure 2 includes a fixed plate 21, a cylinder 22, a telescopic shaft 23, a fixed plate 24, a sliding rail 25, a sliding block 26, and a guide plate 27; Fixed plate 21 is fixedly connected to the outer wall of reactor body 1, cylinder 22 is fixedly connected to one side of fixed plate 21, telescopic shaft 23 is slidably connected to the inner cavity of cylinder 22, fixed plate 24 is fixedly connected to the lower side of telescopic shaft 23, sliding track 25 is fixedly connected to the lower side of fixed plate 24, sliding block 26 is slidably engaged with the lower side of sliding track 25, and guide plate 27 is fixedly installed on the lower side of sliding block 26.

[0021] The adjustment structure 2 drives the telescopic shaft 23 to move up and down via the cylinder 22, which in turn drives the fixed plate 24 and the sliding track 25 to move synchronously. The sliding block 26 slides on the sliding track 25, allowing the guide plate 27 to adjust its position and angle according to the wastewater treatment requirements, thereby optimizing the flow path and reaction efficiency of the wastewater. The reactor body 1 is a three-dimensional electrode reactor, model BDD-MT12, which works by filling granular particle electrodes between the anode and cathode main electrodes. Under the action of an external electric field, the particle electrodes are polarized to form multiple micro "electrolytic cells", thereby achieving efficient degradation of organic matter.

[0022] The cylinder 22 is connected to the fixed plate 24 via the telescopic shaft 23. The fixed plate 24 is connected to the sliding block 26 via the sliding rail 25. Multiple sliding blocks 26 are provided on the lower side of the sliding rail 25. Multiple guide plates 27 are provided on the lower side of the sliding rail 25. The guide plates 27 are connected to the sliding rail 25 via the sliding blocks 26.

[0023] The multiple settings of the sliding slots 210 provide flexible adjustment space for the guide plate 27, further enhancing the controllability of wastewater flow.

[0024] The adjustment structure 2 also includes a sliding column 28, an adjustment plate body 29, and a sliding groove 210; The sliding column 28 is fixedly connected to one side of the guide plate 27, the regulating plate body 29 is slidably connected to one side of the sliding column 28, and the sliding groove 210 is opened in the inner cavity of the regulating plate body 29.

[0025] The regulating plate body 29 is fixedly installed on the inner wall of the reactor body 1. The reactor body 1 is connected to the guide plate 27 through the sliding column 28. Multiple sliding slots 210 are provided on the regulating plate body 29.

[0026] The sliding slot 210 allows the sliding column 28 to move the guide plate 27 along the shape of the sliding slot 210, thus adjusting the spacing between each guide plate 27. For wastewater treatment with a large flow rate, the spacing can be appropriately increased to ensure smooth flow of wastewater. For cases with higher treatment requirements and where it is necessary to increase the contact time between wastewater and electrodes, the spacing can be reduced, allowing the wastewater to flow in a narrower channel and prolonging the residence time.

[0027] A top plate 11 is fixedly installed on the upper side of the reactor body 1. Three slots are opened on the top plate 11, and the telescopic column is slidably connected to the slots.

[0028] The slots on the top plate 11 are slidably connected to the telescopic column, ensuring smooth and airtight movement of the telescopic column. The top plate 11 not only protects the internal structure but also facilitates maintenance and repair, while preventing external impurities from entering the reactor and affecting the treatment effect. Working principle: The adjusting structure 2 drives the telescopic shaft 23 to move up and down via the cylinder 22, which in turn drives the fixed plate 24 and the sliding track 25 to move synchronously. The sliding block 26 slides on the sliding track 25, allowing the guide plate 27 to adjust its position and angle according to the wastewater treatment requirements, thereby optimizing the wastewater flow path and reaction efficiency. The sliding column 28 is fixed to one side of the guide plate 27 and cooperates with the sliding slot 210 on the adjusting plate body 29, allowing the guide plate 27 to adjust the spacing between the guide plates 27 according to the shape of the sliding slot 210, and making it more stable during movement. The slot on the top plate 11 is slidably connected to the telescopic column, ensuring the smoothness and sealing of the telescopic column during up and down movement, while protecting the internal structure and preventing external impurities from entering the reactor.

[0029] This step allows for adjustment of the spacing between the guide plates 27 by adjusting the configuration of structure 2, thus adapting to wastewater treatment with different flow rates.

[0030] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, also includes an aeration structure 3. The aeration structure 3 includes an external air source 31, an aeration pipe 32, and a microporous aeration head 33; An external air source 31 is fixedly connected to the outer wall of the reactor body 1, and an aeration pipe 32 is arranged in a grid pattern at the bottom of the reactor body 1. Microporous aeration heads 33 are evenly distributed on the aeration pipe 32.

[0031] The aeration pipe 32 is connected to the external air source 31. The microporous aeration head 33 is made of a flexible polymer material and has an anti-fouling coating on its surface.

[0032] This flexible polymer material has good flexibility and anti-clogging ability. Its surface is coated with an anti-fouling coating, which can effectively reduce the adhesion of impurities in high-concentration organic wastewater to the surface of the microporous aerator head 33. The pore size of the microporous aerator head 33 is 100-150μm, and the distance between adjacent microporous aerator heads 33 is 20-30cm, ensuring that the gas can be evenly dispersed into the wastewater, forming microbubbles and increasing the gas-liquid contact area.

[0033] Working Principle: The aeration structure 3 receives gas from an external gas source 31. The gas is transported through the aeration pipe 32 to the microporous aeration head 33, forming tiny bubbles that are evenly distributed in the wastewater. By setting the pore size and spacing of the microporous aeration head 33, the gas-liquid contact area can be maximized, improving oxygen transfer efficiency and thus enhancing the electrochemical catalytic oxidation reaction effect. Gas is introduced into the reactor body 1 via aeration, creating a gas stirring effect. As the gas rises, it drives the wastewater flow, achieving mixing and mass transfer. This method not only promotes the contact between organic matter and the electrodes but also washes the electrode surface, reducing pollutant deposition and improving electrode stability and service life.
