Description

Technical Field

[0001] The present invention relates to the technical field of anaerobic ponds, and particularly to an anaerobic pond for industrial wastewater treatment. Background Art

[0002] Industrial wastewater refers to the wastewater containing pollutants generated during industrial production processes, usually including toxic substances and organic matter. In order to treat this wastewater, anaerobic ponds are often used to decompose organic matter by anaerobic microorganisms.

[0003] Traditional anaerobic ponds generally remove pollutants by decomposing organic matter in wastewater by anaerobic microorganisms in an anoxic environment. The specific principle is as follows: After the wastewater enters a closed anaerobic environment, a specific anaerobic microbial community gradually decomposes complex organic matter into simple small-molecule substances through stages such as hydrolysis, acidification, and methane production under anaerobic conditions, and finally converts them into gas products such as methane and carbon dioxide and a small amount of residual sludge, thereby achieving the degradation and transformation of pollutants.

[0004] The above treatment method of traditional anaerobic ponds has advantages such as low energy consumption, low sludge production, and recoverable energy gas, and has been widely used in the field of industrial wastewater treatment. However, since most traditional anaerobic ponds adopt a simple static structure design, it may lead to problems such as insufficient contact between anaerobic microorganisms and wastewater and poor water body fluidity, resulting in uneven residence time distribution, short circuit or dead zone phenomena during the treatment of wastewater, and reducing the pollutant removal efficiency. Therefore, the present invention aims to provide an anaerobic pond for industrial wastewater treatment that can improve the contact efficiency between anaerobic microorganisms and wastewater.

Detailed implementation mode

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0033] Embodiment: Please refer to Figures 1 to 7 , and a technical solution is provided according to the embodiment of the present invention: An anaerobic pool for industrial wastewater treatment includes a pool body 1 having an inner cavity 2, and a water outlet part 3 and a water inlet part 4 communicating with the inner cavity 2 are arranged on the pool body 1; a support frame 5, with both ends protruding upward to form support parts 6, and the pool body 1 is rotatably arranged between the two support parts 6; a driving member for driving the pool body 1 to reciprocally rotate along its axis; and a film-forming member arranged in the inner cavity 2 for enhancing the water body mixing and providing an attachment carrier for anaerobic microorganisms as the pool body 1 reciprocally rotates.

[0034] For the anaerobic pool for industrial wastewater treatment with the above structure, when the user needs to treat the wastewater, first, the wastewater and anaerobic microorganisms enter the inner cavity 2 of the pool body 1 through the water inlet part 4. As the driving member starts, the pool body 1 begins to reciprocally rotate along its axis. At this time, the film-forming member moves accordingly under the reciprocating rotation of the pool body 1, enhancing the mixing effect of the wastewater and anaerobic microorganisms, ensuring full contact between the wastewater and anaerobic microorganisms. During the movement of the film-forming member, anaerobic microorganisms attach to the surface of the film-forming member, decompose the organic matter in the wastewater through anaerobic metabolism, and generate gases such as methane and carbon dioxide, achieving the purpose of wastewater treatment. During the movement of the film-forming member, it continuously contacts the wastewater, providing more surfaces for anaerobic microorganisms to attach and reproduce, enhancing the degradation ability of anaerobic microorganisms. As the pool body 1 reciprocally rotates, the contact time between the wastewater and anaerobic microorganisms is extended, thereby improving the removal rate of organic matter.

[0035] It should be noted that although the reciprocating rotation of the pool body 1 helps to enhance the contact between the wastewater and anaerobic microorganisms, an overly strong rotational movement may have an adverse effect on anaerobic microorganisms. Especially when the rotation speed is too fast, it may cause the anaerobic microorganisms to be unable to effectively adhere to the film-forming components or be overly agitated, affecting their degradation effect. Therefore, users can reasonably control the rotation speed and frequency of the pool body 1 to ensure that while the anaerobic microorganisms are fully mixed, they can maintain stable adhesion and growth.

[0036] In addition, long-term reciprocating rotation may lead to uneven sedimentation of anaerobic microorganisms. Especially when the wastewater concentration is high, the anaerobic microorganism population may be overly suspended and unable to effectively precipitate. To avoid this problem, users can use an intermittent reciprocating rotation mode, enabling the anaerobic microorganisms to sediment and regenerate within a certain period, thereby ensuring the stability and efficiency of the anaerobic microorganism community in the reaction pool.

[0037] In this embodiment, the pool body 1 has a cylindrical structure, and the water outlet part 3 and the water inlet part 4 are respectively arranged at opposite ends of the pool body 1; with such an arrangement, the water inlet part 4 and the water outlet part 3 can conveniently achieve the stable inflow and outflow of wastewater, and the cylindrical pool body 1 facilitates the rotation of the pool body 1.

[0038] In this embodiment, the water inlet part 4 and the water outlet part 3 are configured as hollow pipe bodies, and flange plates 7 are fixedly arranged at the free ends of the water inlet part 4 and the water outlet part 3; the flange plates 7 can conveniently connect with external pipelines or equipment to ensure the sealing and stability of the water inlet and outlet pipelines.

[0039] In this embodiment, the water inlet part 4 is configured as an L-shaped structure with an upward opening; the design of the L-shaped structure helps to control the inflow direction and flow rate of the wastewater, and the upward opening design can prevent the wastewater from directly impacting the bottom of the pool when entering the pool body 1, thereby reducing the disturbance to the anaerobic microorganisms in the pool and maintaining the stability of the biofilm in the pool.

[0040] In this embodiment, the driving member includes a rotating disk 8, a rack 9, a gear 10, a driving member 11, a coupling portion and two guide rods 12; the rotating disk 8 is rotatably arranged on a support portion 6, the rotating disk 8 is fixed to the outer wall of the water inlet portion 4, the rack 9 is a C-shaped structure and is arranged on the first surface of the rotating disk 8, and the first surface of the rotating disk 8 is provided with a C-shaped slide groove 13, and the slide groove 13 is arranged on the edge of the rack 9; a fixing plate 15 is connected to the support frame 5, and the fixing plate 15 is arranged away from the support portion 6. Two guide rods 12 are fixed on the fixed plate 15, and both guide rods 12 are movable through a moving block 16. A rotating shaft 14 is rotatably provided on the moving block 16. The end of the rotating shaft 14 is slidably provided in the slide groove 13. The gear 10 is sleeved on the rotating shaft 14, and the gear 10 is meshed with the rack 9. The rotating shaft 14 is coaxially fixed with the end of the coupling part, and the other end of the coupling part is coaxially fixed with the driving member 11. When the user needs to drive the pool body 1 to reciprocate, first, the driving member 11 is used to provide a driving force. The force drives the coupling part to transmit the power to the rotating shaft 14. At this time, the rotating shaft 14 rotates, driving the gear 10 to rotate. The gear 10 is meshed with the rack 9, and the gear 10 is restricted by the rotating shaft 14 and the moving block 16, so that the gear 10 cannot move left and right. In this way, when the gear 10 is meshed with the rack 9, the rack 9 slides along the slide groove 13 of the rotating disk 8, pushing the rotating disk 8 to rotate, thereby driving the entire pool body 1 to start rotating. Since the slide groove 13 of the rotating disk 8 cooperates with the edge of the rack 9, the rack 9 moves along a predetermined trajectory in the slide groove 13 to ensure that the rotating disk 8 maintains a stable rotation path. When the rotation of the rotating disk 8 causes the end of the rack 9 to contact the gear 10, the gear 10 will move up to the slide groove 13 above the rack 9 through the meshing with the rack 9 (in this process, the gear 10 will drive the coupling part and the moving block 16 to move up), thereby pushing the rotating disk 8 to continue to rotate in the opposite direction until the next end of the rack 9 contacts the gear 10 to achieve reciprocating rotation.

[0041] In this embodiment, the coupling portion includes a coupling member 17, a coupling member 2 18, a coupling member 3 19 and a coupling member 4 20;

[0042] The driving member 11 is configured as a motor; the end of the first coupling member 17 is coaxially fixed to the rotating shaft 14, and two first fixing blocks 21 are provided at intervals at the free end of the first coupling member 17. A first shaft body 25 is rotatably provided between the two first fixing blocks 21. Two second fixing blocks 22 are provided at intervals at the end of the second coupling member 18. A second shaft body 26 is rotatably provided between the two second fixing blocks 22. The second shaft body 26 movably penetrates through the first shaft body 25; a limiting groove 29 is formed at the free end of the second coupling member 18. A limiting rod 30 is fixed to the end of the third coupling member 19. The limiting rod 30 is movably arranged in the limiting groove 29. Two third fixing blocks 23 are provided at intervals at the other end of the third coupling member 19. A third shaft body 27 is rotatably provided between the third fixing blocks 23. The end of the fourth coupling member 20 is coaxially fixed to the output end of the driving member 11. Two fourth fixing blocks 24 are provided at intervals at the free end of the fourth coupling member 20. A fourth shaft body 28 is rotatably provided between the fourth fixing blocks 24. The third shaft body 27 movably penetrates through the fourth shaft body 28; when the user needs to drive the pool body 1 to rotate reciprocally, first, the driving member 11 outputs power, and drives the third coupling member 19 to move accordingly through the fourth coupling member 20 coaxially fixed to its output end. The third coupling member 19 enables the power to be continuously transmitted to the second coupling member 18 through the limiting rod 30. The second coupling member 18 and the first coupling member 17 form a movable nested relationship. The end of the first coupling member 17 is coaxially fixed to the rotating shaft 14. Finally, the power is transmitted to the rotating shaft 14 itself. As the power is introduced, the rotating shaft 14 starts to rotate, and the gear 10 sleeved thereon rotates synchronously. As the gear 10 continuously meshes and rotates, the rack 9 slides along a preset trajectory in the sliding groove 13, thereby pushing the rotating disk 8 to rotate. While the rotating disk 8 rotates, it also drives the pool body 1 to rotate around the axis direction. Since the rack 9 is C-shaped and the path of the sliding groove 13 is also C-shaped, when the rotating disk 8 rotates to a certain angle, the gear 10 will move to the end of the rack 9, and with the help of its fixed structure with the rotating shaft 14 and the moving block 16, as well as the limitation of the sliding groove 13 trajectory, a vertical driving force is generated, enabling the gear 10 to "climb" along the edge of the rack 9 to above another section of the sliding groove 13. During this process, the upward movement of the gear 10 will drive the entire first coupling member 17, second coupling member 18, third coupling member 19 and the moving block 16 to move upward together. When the gear 10 completes the upward movement and continues to mesh with a new section of the rack 9, the driving direction is reversed, and the rack 9 starts to slide in the sliding groove 13 in the reverse direction, and the rotating disk 8 also rotates in the reverse direction accordingly, thereby enabling the pool body 1 to enter the reverse rotation stage. In this way, when the rotating disk 8 rotates to the other end, the gear 10 will "descend" back to the initial position along the sliding groove 13, and the first coupling member 17, second coupling member 18, third coupling member 19 and the moving block 16 also reset downward, completing a complete reciprocating rotation cycle.

[0043] In this embodiment, a limiting top 31 is provided at the ends of the two guide rods 12; with such a setting, when the coupling part starts to move upward, the limiting top 31 will limit the moving block 16 from moving out of the guide rods 12.

[0044] In this embodiment, the film-forming member includes a plurality of support rods 32 fixedly arranged along the axial direction of the pool body 1 in the inner cavity 2 and a plurality of filter plates 33 movably sleeved on each support rod 32. With such an arrangement, the filter plates 33 can move along with the reciprocating rotation of the pool body 1. Each filter plate 33 comes into full contact with the wastewater during the rotation process, increasing the contact area between the wastewater and the anaerobic microorganisms, which helps the anaerobic microorganisms to adhere to its surface and form a biofilm. At the same time, the mobility of the filter plates 33 enables them to adapt to the liquid flow in the pool during the rotation process, preventing the excessive deposition of anaerobic microorganisms and solid particles on the surface of the filter plates 33 and ensuring the continuous formation of the biofilm and the anaerobic microorganism degradation process.

[0045] In this embodiment, a scrubbing filter brush 34 is provided at the end of the filter plate 33. With such an arrangement, the scrubbing filter brush 34 can perform dynamic cleaning when the pool body 1 reciprocates and rotates, preventing the excessive accumulation of anaerobic microorganisms and solid particles on the inner wall of the inner cavity 2. At the same time, the scrubbing filter brush 34 also acts as a filtering structure, enabling anaerobic microorganisms to adhere to its surface, form a biofilm, and further degrade the organic matter in the wastewater through the anaerobic metabolism of the anaerobic microorganisms.

[0046] In this embodiment, locking valves are arranged in both the water inlet part 4 and the water outlet part 3. With such an arrangement, it is convenient to effectively control the water inlet and outlet when needed, so as to quickly cut off the water flow during maintenance, repair, or adjustment processes and prevent the wastewater from leaking.

[0047] Working principle: When the user needs to treat wastewater, first, the wastewater and anaerobic microorganisms enter the inner cavity 2 of the tank body 1 through the water inlet part 4. With the power output by the driving part 11, the coupling part three 19 is driven to move along with the coupling part four 20 fixedly connected to its output end coaxially. The power is continuously transmitted to the coupling part two 18 through the limiting rod 30 by the coupling part three 19. The coupling part two 18 and the coupling part one 17 form a movable nested relationship. The end of the coupling part one 17 is fixedly connected to the rotating shaft 14 coaxially. Finally, the power is transmitted to the rotating shaft 14 itself. With the power input, the rotating shaft 14 starts to rotate, and the gear 10 sleeved on it rotates synchronously. With the continuous meshing rotation of the gear 10, the rack 9 slides along the preset track in the chute 13, thereby pushing the rotating disk 8 to rotate. While the rotating disk 8 rotates, it also drives the tank body 1 to rotate around the axis direction. Since the rack 9 is C-shaped and the path of the chute 13 is also C-shaped, when the rotating disk 8 rotates to a certain angle, the gear 10 will move to the end of the rack 9 and, with the help of its fixed structure with the rotating shaft 14 and the moving block 16 and the limitation of the chute 13 track, generate a vertical driving force, so that the gear 10 "climbs" along the edge of the rack 9 to above another section of the chute 13. During this process, the upward movement of the gear 10 will drive the entire coupling part one 17, coupling part two 18, coupling part three 19 and the moving block 16 to move upward together. When the gear 10 completes the upward movement and continues to mesh with a new section of the rack 9, the driving direction is reversed, the rack 9 starts to slide in the chute 13 in the opposite direction, and the rotating disk 8 also rotates in the opposite direction, so that the tank body 1 enters the reverse rotation stage. In this way, when the rotating disk 8 rotates to the other end, the gear 10 will "descend" back to the initial position along the chute 13, and the coupling part one 17, coupling part two 18, coupling part three 19 and the moving block 16 also return to their original positions downward, completing a complete reciprocating rotation cycle. At this time, the filter plate 33 can move along with the reciprocating rotation of the tank body 1. Each filter plate 33 is in full contact with the wastewater during the rotation process, increasing the contact area between the wastewater and the anaerobic microorganisms, which helps the anaerobic microorganisms to adhere to its surface and form a biofilm. At the same time, the mobility of the filter plate 33 enables it to adapt to the liquid flow in the tank during the rotation process, avoiding excessive deposition of anaerobic microorganisms and solid particles on the surface of the filter plate 33, ensuring the continuous formation of the biofilm and the anaerobic degradation process of the anaerobic microorganisms. The scrubbing filter wool 34 can be dynamically cleaned when the tank body 1 reciprocates, preventing excessive accumulation of anaerobic microorganisms and solid particles on the inner wall of the inner cavity 2. At the same time, the scrubbing filter wool 34 also acts as a filtering structure, enabling anaerobic microorganisms to adhere to its surface, form a biofilm, and further degrade the organic matter in the wastewater through the anaerobic metabolism of the anaerobic microorganisms. With the reciprocating rotation of the tank body 1, the contact time between the wastewater and the anaerobic microorganisms is extended, thereby improving the removal rate of the organic matter.

[0048] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art will appreciate that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
