Description

Technical Field

[0001] This invention belongs to the field of wastewater treatment technology, specifically an anaerobic treatment device based on biochar packing reinforcement. Background Technology

[0002] In the field of wastewater treatment, anaerobic treatment has the advantages of high load, low energy consumption and small amount of residual sludge, making it the preferred method for treating medium and high concentration organic wastewater.

[0003] Biochar packing is one type of biological packing material for wastewater treatment, also known as fluidized bed packing. It is a highly efficient wastewater treatment method that combines the advantages of traditional fluidized bed and biological contact anaerobic processes. Currently, in equipment that uses biochar packing to treat wastewater, the biochar packing is filled inside the treatment tank. When wastewater needs to be treated, it is introduced into the treatment tank and passes through the biochar packing. During this process, because the wastewater has a short flow path inside the treatment tank, the contact time between the wastewater and the biochar packing is relatively limited, resulting in an unsatisfactory treatment effect of the biochar packing for wastewater. Summary of the Invention

[0004] To address the shortcomings of the prior art, the technical problem to be solved by the embodiments of the present invention is to provide an anaerobic treatment device based on biochar packing reinforcement.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: An anaerobic treatment device based on biochar filler reinforcement includes a housing, a first storage tank, a second storage tank, a connecting tank, a sealing assembly, a driving assembly, and an elastic assembly. A water inlet pipe is provided at the bottom of the side wall of the box, and a water outlet pipe is provided at the top of the side wall of the box. The first and second storage bins are fixedly installed inside the housing and are arranged opposite each other on the left and right sides. The first and second storage bins are used to store biochar filler. The first storage bin has a first slot on its upper and lower side walls, and the second storage bin has a second slot on its upper and lower sides. The connecting box is disposed between the first storage box and the second storage box, and is used to connect the first storage box and the second storage box. The sealing assembly comprises four sets, which are respectively disposed on the upper and lower sides of the first storage box and the second storage box. The driving component and the elastic component are disposed inside the housing. The driving component and the elastic component cooperate to drive the four sets of sealing components to move, so that the first slot and the second slot located on one diagonal line open, and the first slot and the second slot located on the other diagonal line close.

[0006] As a further improvement of the present invention: the first storage box includes a first top plate and a first bottom plate. The first top plate and the first bottom plate are distributed at intervals between each other. The first top plate and the first bottom plate are fixedly installed on the left side wall inside the box. A first chamber is formed between the first top plate and the first bottom plate. The first slot is provided on both the first top plate and the first bottom plate.

The third top plate and the third bottom plate are spaced vertically apart. Both ends of the third top plate and the third bottom plate are fixedly provided with inclined plates. The four sets of inclined plates are fixedly connected to the first top plate, the first bottom plate, the second top plate, and the second bottom plate, respectively. The third top plate and the third bottom plate form a third chamber for connecting the first chamber and the second chamber.

[0009] As a further improvement of the present invention: a few interference flow rods are fixedly arranged between the third top plate and the third bottom plate.

[0010] As a further improvement to the present invention: the four sets of sealing components have the same structure, all including a sealing plate. The sealing plates corresponding to two sets of sealing components are respectively disposed on the upper part of the first top plate and the second top plate, and the sealing plates corresponding to the other two sets of sealing components are respectively disposed on the lower part of the first bottom plate and the second bottom plate. A third groove is provided on all four sets of sealing plates.

[0011] As a further improvement to the present invention: the sealing assembly further includes a piston sleeve and a U-shaped tube. The piston sleeves are provided in four sets, and the four sets of piston sleeves are respectively fixedly installed on the side walls of the four sets of sealing plates. The U-shaped tubes are provided in two sets. The vertical portion of one set of U-shaped tubes penetrates through the first top plate and the first bottom plate, and the horizontal portion of this set of U-shaped tubes extends into the interior of two sets of piston sleeves. The vertical portions of the other two sets of U-shaped tubes penetrate through the second top plate and the second bottom plate, and the horizontal portions of this set of U-shaped tubes extend into the interior of the other two sets of piston sleeves. The drive assembly includes an arc-shaped block, a rotating wheel, a rotating shaft, and a motor. The motor is fixedly mounted on the outer wall of the housing. One end of the rotating shaft is connected to the output end of the motor, and the other end extends into the housing. The rotating wheel is fixedly mounted on the shaft located inside the housing, and the arc-shaped block is fixedly mounted on the circumferential side wall of the rotating wheel. The elastic component includes a push rod, a slide rod, and an elastic element. The slide rod is provided in two sets. The two sets of slide rods are respectively fixedly installed at the bottom of the two sets of sealing plates located at the lower position. The two sets of slide rods are distributed in a left-right opposite direction. A set of top rods is fixedly installed on the opposite side of the two sets of slide rods. The side of the two sets of slide rods that are far apart from each other is connected to the inner wall of the box through a set of elastic elements.

[0012] As a further improvement of the present invention: the elastic component further includes a guide rod, which is fixedly disposed on the inner wall of the box, and the two sets of slide rods are slidably sleeved on the outside of the guide rod.

[0013] As a further improvement of the present invention: the elastic element is a spring or a metal sheet.

[0014] As a further improvement of the present invention: both the first slot and the second slot are fitted with a mesh.

[0015] Compared with the prior art, the beneficial effects of the present invention are: In this embodiment of the invention, initially, the first slot on the bottom wall of the first storage tank is open, the first slot on the top wall of the first storage tank is closed, the second slot on the bottom wall of the second storage tank is closed, and the second slot on the top wall of the second storage tank is open. The biochar filler is concentrated inside the first storage tank. When wastewater needs to be treated, the wastewater can be pumped from the inlet pipe to the bottom of the tank. After entering the bottom of the tank, the wastewater passes through the first slot on the bottom wall of the first storage tank from bottom to top and enters the first storage tank. Then, the wastewater, carrying the biochar filler, gradually enters the second storage tank to the right through the connecting box. After the wastewater enters the second storage tank, it passes through the first... The second slot on the top wall of the second storage tank outputs wastewater, while the biochar filler remains inside the second storage tank after entering. Once all the biochar filler is entrained by the wastewater into the second storage tank, the drive component and the elastic component work together to move the four sets of sealing components. When the sealing component above the first storage tank moves, it closes the first slot on the top wall of the first storage tank; when the sealing component below the first storage tank moves, it opens the first slot on the bottom wall of the first storage tank. When the sealing component above the second storage tank moves, it closes the second slot on the top wall of the second storage tank; when the sealing component below the second storage tank moves, it closes the second slot on the bottom wall of the second storage tank. The inlet is opened, and the wastewater entering the bottom of the inner tank enters the second storage tank through the second slot on the bottom wall of the second storage tank. It then carries the biochar packing material inside the second storage tank and gradually flows to the left through the connecting box into the first storage tank. Once the wastewater enters the first storage tank, it exits through the first slot on the top wall of the first storage tank. The biochar packing material remains inside the first storage tank. When all the biochar packing material is carried into the first storage tank by the wastewater, the drive component and the elastic component work together to move the four sets of sealing components in the opposite direction. The two sets of first slots and the two sets of second slots return to their initial state, and the wastewater entering the bottom of the inner tank re-enters the first storage tank. Inside the material tank, the biochar packing material from the first storage tank is gradually transferred to the second treatment tank via a connecting box. This cycle repeats, allowing the biochar packing material to move repeatedly between the first storage tank and the second treatment tank along with the wastewater. This repeated flow of wastewater prolongs the contact time between the biochar packing material and the wastewater, thereby improving the wastewater treatment effect. After the wastewater is discharged through the first slot on the top wall of the first storage tank and the second slot on the top wall of the second storage tank, it can be discharged to the outside of the tank through an outlet pipe. Compared to existing technologies, this method prolongs the contact time between the wastewater and the biochar packing material during wastewater treatment, thus improving the wastewater treatment effect.

[0021] Please see Figures 1-7 This embodiment provides an anaerobic treatment device based on biochar filler reinforcement, including a housing 10, a first storage tank 20, a second storage tank 30, a connecting tank 40, a sealing assembly 50, a driving assembly 60, and an elastic assembly 70. A water inlet pipe 101 is provided at the bottom of the side wall of the housing 10, and a water outlet pipe 102 is provided at the upper part of the side wall of the housing 10. The first storage tank 20 and the second storage tank 30 are fixedly installed inside the housing 10 and are arranged in a left-right opposite distribution. The first storage tank 20 and the second storage tank 30 are used to store biochar filler. First slots 204 are opened on the upper and lower side walls of the first storage tank 20, and second slots 304 are opened on the upper and lower sides of the second storage tank 30. A connecting box 40 is disposed between the first storage box 20 and the second storage box 30 to connect the first storage box 20 and the second storage box 30. The sealing assembly 50 is provided in four sets, which are respectively disposed on the upper and lower sides of the first storage box 20 and the second storage box 30. The driving assembly 60 and the elastic assembly 70 are disposed inside the box body 10. The driving assembly 60 and the elastic assembly 70 cooperate to drive the four sets of sealing assemblies 50 to move, so that the first slot 204 and the second slot 304 located on one diagonal line open, and the first slot 204 and the second slot 304 located on the other diagonal line close.

[0022] Initially, the first slot 204 on the bottom wall of the first storage tank 20 is open, and the first slot 204 on the top wall of the first storage tank 20 is closed. The second slot 304 on the bottom wall of the second storage tank 30 is closed, and the second slot 304 on the top wall of the second storage tank 30 is open. The biochar packing is concentrated inside the first storage tank 20. When wastewater needs to be treated, the wastewater can be pumped from the inlet pipe 101 to the bottom of the tank 10. After entering the bottom of the tank 10, the wastewater passes through the first slot 204 on the bottom wall of the first storage tank 20 from bottom to top and enters the first storage tank 20. Then, the wastewater, carrying the biochar packing, gradually flows to the right through the connecting box 40 into the second storage tank 20. Inside the second storage tank 30, wastewater enters and exits through the second slot 304 on the top wall of the second storage tank 30. Biochar filler, after entering the second storage tank 30, remains inside. When all the biochar filler is entrained by the wastewater into the second storage tank 30, the drive component 60 and the elastic component 70 cooperate to move the four sets of sealing components 50. When the sealing component 50 above the first storage tank 20 moves, it closes the first slot 204 on the top wall of the first storage tank 20. When the sealing component 50 below the first storage tank 20 moves, it opens the first slot 204 on the bottom wall of the first storage tank 20. The sealing component 50 above the second storage tank 30... When the sealing component 50 moves, it closes the second slot 304 on the top wall of the second storage tank 30. When the sealing component 50 located below the second storage tank 30 moves, it opens the second slot on the bottom wall of the second storage tank 30. At this time, the sewage that subsequently enters the bottom of the inner side of the tank 10 enters the interior of the second storage tank 30 through the second slot 304 on the bottom wall of the second storage tank 30. Then, carrying the biochar packing material inside the second storage tank 30, it gradually enters the interior of the first storage tank 20 to the left through the connecting box 40. After the sewage enters the interior of the first storage tank 20, it is discharged through the first slot 204 on the top wall of the first storage tank 20. The biochar packing material remains inside the first storage tank 20 after entering it. After the biochar packing is carried into the first storage tank 20 by the sewage, the drive component 60 and the elastic component 70 cooperate to drive the four sets of sealing components 50 to move in the opposite direction. The two sets of first slots 204 and the two sets of second slots 304 return to their initial state. Subsequently, the sewage entering the bottom of the inner side of the tank 10 re-enters the first storage tank 20, so as to carry the biochar packing inside the first storage tank 20 into the second treatment tank 30 through the connecting box 40. This cycle repeats, allowing the biochar packing to move repeatedly between the first storage tank 20 and the second treatment tank 30 with the sewage. During the repeated flow of the sewage, the contact time between the sewage and the biochar packing can be extended, thereby improving the sewage treatment effect.The wastewater, after being discharged through the first slot 204 on the top wall of the first storage tank 20 and the second slot 304 on the top wall of the second storage tank 30, can be discharged to the outside of the tank body 10 through the outlet pipe 102.

[0023] Please see Figure 1 , Figure 5 as well as Figure 6 In one embodiment, the first storage box 20 includes a first top plate 201 and a first bottom plate 202, which are arranged vertically at intervals. The first top plate 201 and the first bottom plate 202 are fixedly installed on the inner left side wall of the box body 10, and a first chamber 203 is formed between the first top plate 201 and the first bottom plate 202. The first slot 204 is provided on both the first top plate 201 and the first bottom plate 202. The second storage box 30 includes a second top plate 301 and a second bottom plate 302, which are arranged vertically at intervals. The second top plate 301 and the second bottom plate 302 are fixedly installed on the inner right side wall of the box body 10, and a second chamber 303 is formed between the second top plate 301 and the second bottom plate 302. The second slot 304 is provided on both the second top plate 301 and the second bottom plate 302.

[0024] When the first slot 204 on the first bottom plate 202 is open, the second slot 304 on the second top plate 301 is also open, while the first slot 204 on the first top plate 201 and the second slot 304 on the second bottom plate 302 are closed. At this time, sewage can enter the first chamber 203 and carry biochar packing material through the connecting box 40 into the second chamber 303. When the second slot 304 on the second bottom plate 302 is open, the first slot 204 on the first top plate 201 is also open, while the first slot 304 on the second top plate 301 and the first slot 204 on the first bottom plate 202 are closed. At this time, sewage can enter the second chamber 303 and carry biochar packing material through the connecting box 40 into the first chamber 203.

[0025] Please see Figure 1 as well as Figure 2In one embodiment, the communicating box 40 includes a third top plate 401 and a third bottom plate 405. The third top plate 401 and the third bottom plate 405 are spaced vertically apart. Inclined plates 402 are fixedly provided at both ends of the third top plate 401 and the third bottom plate 405. The four sets of inclined plates 402 are fixedly connected to the first top plate 201, the first bottom plate 202, the second top plate 301, and the second bottom plate 302, respectively. A third chamber 403 for communicating between the third top plate 401 and the third bottom plate 405 is formed.

[0026] When the first slot 204 on the first bottom plate 202 and the second slot 304 on the second top plate 301 are open, sewage enters the first chamber 203 and carries biochar packing material through the third chamber 405 into the second chamber 303. Subsequently, the sewage is discharged from the open second slot 304. Please see Figure 1 as well as Figure 2 In one embodiment, a few interference flow rods 404 are fixedly disposed between the third top plate 401 and the third bottom plate 405.

[0027] As the wastewater carrying the biochar packing material flows along the third chamber 403, the flow disturbance rod 404 can agitate the flowing wastewater and biochar packing material to slow down the flow rate of the wastewater, thereby further extending the contact time between the wastewater and the biochar packing material and further improving the wastewater treatment effect.

[0028] Please see Figure 4 , Figure 5 , Figure 6 as well as Figure 7 In one embodiment, the four sets of sealing components 50 have the same structure and each includes a sealing plate 501. The sealing plates 501 corresponding to two sets of sealing components 50 are respectively disposed on the upper part of the first top plate 201 and the second top plate 301, and the sealing plates 501 corresponding to the other two sets of sealing components 50 are respectively disposed on the lower part of the first bottom plate 202 and the second bottom plate 302. A third slot 502 is provided on each of the four sets of sealing plates 501.

[0029] Initially, the third slot 502 on the sealing plate 501 above the first top plate 201 is misaligned with the first slot 204 on the first top plate 201, and the sealing plate 501 seals the first slot 204; the third slot 502 on the sealing plate 501 below the second bottom plate 302 is misaligned with the second slot 304 on the second bottom plate 302, and the sealing plate seals the second slot 304; the third slot 502 on the sealing plate 501 below the first bottom plate 202 is misaligned with the first slot 204 on the first bottom plate 202. The first slot 204 is in a connected state, and the third slot 502 on the sealing plate 501 above the second top plate 301 is in a connected state with the second slot 304 on the second top plate 301. At this time, the sewage entering the bottom of the inner side of the tank 10 passes through the connected third slot 502 and the first slot 204 and enters the first chamber 203. Then, it carries the biochar packing material from the third chamber 403 into the second chamber 303. When all the biochar packing material has entered the second chamber 303, the drive component 60 and the elastic component... The 70 components work together to move four sets of sealing plates 501. When the sealing plate 501 above the first top plate 201 moves, the third groove 502 on the sealing plate 501 communicates with the first groove 204 on the first top plate 201. When the sealing plate 501 below the second bottom plate 302 moves, the third groove 502 on the sealing plate 501 communicates with the second groove 304 on the second bottom plate 302. And when the sealing plate 501 below the first bottom plate 202 moves, the third groove 502 on the sealing plate 501 communicates with the first groove 204 on the first bottom plate 202. The first slot 204 is misaligned to achieve a seal. When the sealing plate 501 above the second top plate 301 moves, the third slot 502 on the sealing plate 501 is misaligned with the second slot 304 on the second top plate 301 to achieve a reset of the second slot 304. At this time, the subsequent sewage entering the bottom of the inner side of the tank 10 passes through the connected third slot 502 and second slot 304 and enters the interior of the second chamber 203. Then, carrying the biochar packing, it enters the interior of the first chamber 203 from the third chamber 403.

[0030] Please see Figure 3 , Figure 4 , Figure 5 , Figure 6 as well as Figure 7In one embodiment, the sealing assembly 50 further includes piston sleeves 503 and U-shaped tubes 504. Four sets of piston sleeves 503 are provided, each fixedly mounted on the sidewall of one of the four sets of sealing plates 501. Two sets of U-shaped tubes 504 are provided. The vertical portion of one set of U-shaped tubes 504 penetrates the first top plate 201 and the first bottom plate 202, and the horizontal portion of this set extends into the interior of two sets of piston sleeves 503. The vertical portions of the other two sets of U-shaped tubes 504 penetrate the second top plate 301 and the second bottom plate 302, and the horizontal portions of these sets extend into the interior of the other two sets of piston sleeves 503. The driving assembly 60 includes an arc-shaped block 601, a rotating wheel 602, a rotating shaft 603, and a motor 604. The motor 604 is fixedly installed on the outer wall of the housing 10. One end of the rotating shaft 603 is connected to the output end of the motor 604, and the other end extends into the housing 10. The rotating wheel 602 is fixedly installed on the shaft of the rotating shaft 603 located inside the housing 10. The arc-shaped block 601 is fixedly installed on the circumferential side wall of the rotating wheel 603. The elastic component 70 includes a top rod 701, a slide rod 702, and an elastic element 703. There are two sets of slide rods 702. The two sets of slide rods 702 are respectively fixedly installed at the bottom of the two sets of sealing plates 501 located at the lower position. The two sets of slide rods 702 are distributed in a left-right opposite direction. A set of top rods 701 is fixedly installed on the opposite side of the two sets of slide rods 702. The sides of the two sets of slide rods 702 that are far apart from each other are connected to the inner wall of the housing 10 through a set of elastic elements 703.

[0031] While the sewage is pumped from the inlet pipe 101 to the bottom of the tank 10, the motor 604 is started. The motor 604 drives the rotating shaft 603, the rotating wheel 602, and the arc-shaped block 601 to rotate. When the arc-shaped block 601 rotates, it alternately acts on the two sets of push rods 701. When all the biochar packing material in the first chamber 203 has entered the second chamber 303, the rotating arc-shaped block 601 separates from the push rod 701 on the left side and simultaneously acts on the push rod 701 on the right side. At this time, the left elastic element 703 pushes the left sliding rod 702, which in turn drives the first bottom plate 202. The lower sealing plate 501 moves to the right, and the third slot 502 on the sealing plate 501 is misaligned with the first slot 204 on the first base plate 202, thus sealing the first slot 204. When the sealing plate 501 below the first base plate 202 moves to the right, it drives the piston sleeve 503 on its side wall to move to the right simultaneously. At this time, the piston sleeve 503 draws air from the corresponding U-shaped tube 504, causing the piston sleeve 503 above the first top plate 201 to move to the left. This leftward movement of the piston sleeve 503 drives the piston sleeve 501 above the first top plate 201 to move to the left. The third slot 502 on the upper piston sleeve 501 is connected to the first slot 204 on the first top plate 201; when the arc block 601 acts on the right push rod 701, it can push the push rod 701 to move the right slide rod 702 to the right. When the right slide rod 702 moves to the right, it drives the sealing plate 501 below the second bottom plate 302 to move to the right. When the sealing plate 501 moves to the right, the third slot 502 on it is connected to the second slot 304 on the second bottom plate 302. When the right sealing plate 501 moves to the right, it drives the piston sleeve 503 on its side wall to move to the right. At this time, the piston sleeve 503... 03. Pressing the air inside the corresponding U-shaped tube 504 causes the piston sleeve 503 above the second top plate 301 to move to the left. When the piston sleeve 503 moves to the left, it drives the sealing plate 501 above the second top plate 301 to move to the left. At this time, the third slot 502 on the piston plate 501 above the second top plate 301 is misaligned with the second slot 304 on the second top plate 301, thus sealing the second slot 304. At this time, the sewage that subsequently enters the bottom of the inner side of the tank 10 enters the second chamber 303 and carries the biochar packing through the third chamber 403 into the first chamber 203.

[0032] Please see Figure 1 In one embodiment, the elastic component 70 further includes a guide rod 704, which is fixedly disposed on the inner wall of the housing 10, and two sets of slide rods 702 are slidably sleeved on the outside of the guide rod 704.

[0033] The sliding engagement of the two sets of slide rods 702 and guide rods 704 provides guidance for the movement of the sealing plate 501, thereby improving the sealing effect and sealing release effect of the first groove 204 and the second groove 304.

[0034] In one embodiment, the elastic element 703 can be a spring or a metal sheet, and there is no limitation on this.

[0035] Please see Figure 5 as well as Figure 6 In one embodiment, both the first slot 204 and the second slot 304 are fitted with a mesh.

[0036] By setting up a screen, the biochar packing material entering the first chamber 203 and the second chamber 303 can be blocked, thereby preventing sewage from carrying the biochar packing material out of the first chamber 203 and the second chamber 303.

[0037] In this embodiment of the invention, initially, the first slot 204 on the bottom wall of the first storage tank 20 is open, the first slot 204 on the top wall of the first storage tank 20 is closed, the second slot 304 on the bottom wall of the second storage tank 30 is closed, and the second slot 304 on the top wall of the second storage tank 30 is open. The biochar filler is concentrated inside the first storage tank 20. When wastewater needs to be treated, the wastewater can be pumped from the inlet pipe 101 to the bottom of the tank 10. After entering the bottom of the tank 10, the wastewater passes through the first slot 204 on the bottom wall of the first storage tank 20 from bottom to top and enters the interior of the first storage tank 20. Then, the wastewater carrying the biochar filler gradually passes through the connecting box 4. The wastewater enters the second storage tank 30 to the right. After entering the second storage tank 30, the wastewater exits through the second slot 304 on the top wall of the second storage tank 30. The biochar filler, after entering the second storage tank 30, remains inside. Once all the biochar filler is entrained by the wastewater into the second storage tank 30, the drive component 60 and the elastic component 70 cooperate to move the four sets of sealing components 50. When the sealing component 50 above the first storage tank 20 moves, it closes the first slot 204 on the top wall of the first storage tank 20. When the sealing component 50 below the first storage tank 20 moves, it opens the first slot 204 on the bottom wall of the first storage tank 20. The sealing component 50 located above the first storage tank 20 closes the first slot 204 on the top wall of the first storage tank 20. When the upper sealing component 50 moves, it closes the second slot 304 on the top wall of the second storage tank 30. When the lower sealing component 50 moves, it opens the second slot on the bottom wall of the second storage tank 30. At this time, the sewage that subsequently enters the bottom of the inner side of the tank 10 enters the interior of the second storage tank 30 through the second slot 304 on the bottom wall of the second storage tank 30. Then, carrying the biochar packing material inside the second storage tank 30, it gradually enters the interior of the first storage tank 20 to the left through the connecting box 40. After the sewage enters the interior of the first storage tank 20, it is discharged through the first slot 204 on the top wall of the first storage tank 20. The biochar packing material remains inside the first storage tank 20 after entering it. After all the biochar packing material is carried into the first storage tank 20 by the sewage, the drive component 60 and the elastic component 70 cooperate to drive the four sets of sealing components 50 to move in the opposite direction. The two sets of first slots 204 and the two sets of second slots 304 return to their initial state. Subsequently, the sewage entering the bottom of the inner side of the tank 10 re-enters the first storage tank 20, so as to carry the biochar packing material inside the first storage tank 20 into the second treatment tank 30 through the connecting box 40. This cycle repeats, allowing the biochar packing material to move repeatedly between the first storage tank 20 and the second treatment tank 30 with the sewage. During the repeated flow of the sewage, the contact time between the sewage and the biochar packing material can be extended, thereby improving the sewage treatment effect.The wastewater, after exiting through the first slot 204 on the top wall of the first storage tank 20 and the second slot 304 on the top wall of the second storage tank 30, can be discharged to the outside of the tank 10 through the outlet pipe 102. Compared with the prior art, this method can prolong the contact time between wastewater and biochar filler when treating wastewater, thereby improving the wastewater treatment effect.

[0038] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
