An anaerobic-aerobic integrated treatment device for landfill leachate

Abstract

This utility model relates to the field of leachate treatment technology, specifically to an integrated anaerobic and aerobic treatment device for landfill leachate. It includes a treatment frame, with a partition plate fixedly connected inside the frame. Two anaerobic packing materials are arranged on one side of the partition plate, and two aerobic packing materials are arranged on the other side. A fixed pipe connects to the top of the treatment frame, and an adjusting mechanism and an adjusting mechanism are arranged inside the frame. In this utility model, a rotating pipe is rotatably connected to the fixed plate, allowing the rotating pipe to rotate relative to the fixed plate. This causes the conveying frame and the air outlet to rotate within the treatment frame. The leachate is then conveyed through the conveying frame to the bottom of the two anaerobic packing materials, ensuring sufficient contact between the leachate and the entire interior of the packing materials. This facilitates anaerobic treatment of the leachate and allows for more uniform mixing of air within the leachate, thus maintaining the oxygen content of the leachate in the aerobic zone.

Description

Technical Field

[0001] This utility model relates to the field of leachate treatment technology, specifically a landfill leachate integrated anaerobic and aerobic treatment device. Background Technology

[0002] Landfill leachate refers to secondary pollutants generated during the landfilling and disposal process due to rainwater rinsing, scouring, and soaking by surface and groundwater. These pollutants are extracted, hydrolyzed, and fermented. Aerobic-anaerobic integrated treatment technology is frequently used to treat landfill leachate. This process connects the anaerobic stage and the aerobic stage in series. In the anaerobic stage, large organic molecules are broken down into smaller ones, and insoluble organic matter is converted into soluble organic matter. In the aerobic stage, microorganisms attached to the packing material carry out biochemical degradation, removing various organic substances from the wastewater.

[0003] In existing integrated anaerobic-aerobic treatment devices for landfill leachate, the leachate is typically transported to a single location within the device via pipelines. This means the leachate may only pass through a portion of the anaerobic packing material, potentially resulting in some packing material not coming into contact with new leachate. This is detrimental to the continuous treatment of the leachate. Furthermore, when air is introduced into the aerobic treatment section, it tends to rise along a fixed path, hindering the mixing of air and leachate. Utility Model Content

[0004] The purpose of this invention is to provide an integrated anaerobic and aerobic treatment device for landfill leachate to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An integrated anaerobic and aerobic treatment device for landfill leachate includes a treatment frame. A partition is fixedly connected inside the treatment frame. Two anaerobic packing materials are arranged on one side of the partition, and two aerobic packing materials are arranged on the other side. A fixed pipe connects to the top of the treatment frame. An adjusting mechanism 1 and an adjusting mechanism 2 are arranged inside the treatment frame. The adjusting mechanism 1 and the adjusting mechanism 2 have the same structure. The adjusting mechanism 1 includes a fixed plate, which is rotatably connected to a rotating pipe. A conveying pipe is connected to the bottom of the rotating pipe, and two conveying frames are connected to the bottom of the conveying pipe. Several air outlets are connected to the top of the conveying pipe of the adjusting mechanism 2. The partition is located between the adjusting mechanism 1 and the adjusting mechanism 2. The adjusting mechanism 1 is located between the two anaerobic packing materials, and the adjusting mechanism 2 is located between the two aerobic packing materials. The fixed pipe corresponds to the top of the aerobic packing materials.

[0007] Furthermore, a second partition is fixedly connected inside the processing frame, and there is a certain gap between the bottom surface of the second partition and the bottom surface inside the processing frame. The second partition is located on the side of the first partition close to the second aerobic packing material.

[0008] Furthermore, the bottom of the conveying pipe of the second regulating mechanism is fixedly connected to two agitators.

[0009] Furthermore, a drive box that is rotatably connected to the top of the fixed plate is fixedly connected to the top of the rotating tube, and a connecting tube that is fixedly connected to the top of the rotating tube is rotatably connected to the top of the drive box.

[0010] Furthermore, a drive motor is fixedly connected inside the drive box, and a drive shaft that is rotatably connected to the output end of the drive motor is driven by the drive box. Both the drive shaft and the rotating tube are fixedly fitted with connecting gears, and the two connecting gears mesh and transmit power.

[0011] Preferably, the second adjustment mechanism is provided with a limiting mechanism, which includes a sliding ring. The sliding ring is slidably connected to the rotating tube of the second adjustment mechanism. The sliding ring is fixedly connected to two baffles. Each baffle is fixedly connected to a triangular plate that is fixedly connected to the sliding ring. The bottom surface of the baffle is flush with the top of the adjacent air outlet.

[0012] Furthermore, the sliding ring is slidably connected to a fixed ring, the fixed ring is fixedly connected to the rotating tube of the second adjusting mechanism, and a return spring fixedly connected to the top of the sliding ring and fixedly connected to the fixed ring.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. A rotating pipe is rotatably connected to a fixed plate, allowing leachate to be introduced into the rotating pipe of adjustment mechanism one. The leachate can flow out from the conveying frame at the bottom of the conveying pipe, and air can be introduced into the rotating pipe of adjustment mechanism two, causing the air to escape from the air outlet. This allows the rotating pipe to rotate relative to the fixed plate, driving the conveying pipe to rotate, which in turn causes the conveying frame and the air outlet to rotate within the treatment frame. In this way, the leachate can be conveyed to the bottom of the two anaerobic packing materials one through the conveying frame, ensuring that the leachate is in full contact with the entire interior of the anaerobic packing material one, which is beneficial for the anaerobic treatment of the leachate. Furthermore, the rotation of the stirring plate within the treatment frame allows the air to be mixed more evenly in the leachate, which helps to maintain the oxygen content of the leachate in the aerobic zone.

[0021] 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.

[0022] Please see Figure 1-5In this embodiment of the present invention, an integrated anaerobic and aerobic treatment device for landfill leachate includes a treatment frame 10. A partition 11 is fixedly connected inside the treatment frame 10. Two anaerobic packing materials 40 are arranged on one side of the partition 11, and two aerobic packing materials 50 are arranged on the other side. A fixed pipe 13 connects to the top of the treatment frame 10. An adjusting mechanism 20 and an adjusting mechanism 30 are arranged inside the treatment frame 10. The fixed pipe 13 corresponds to the top of the aerobic packing materials 50. The partition 11 is located between the adjusting mechanism 20 and the adjusting mechanism 30. The adjusting mechanism 20 is located between the two anaerobic packing materials 40, and the adjusting mechanism 30 is located between the two aerobic packing materials 50. The rotating pipe 22 of the adjusting mechanism 20 passes through the two anaerobic packing materials 40. Between the two aerobic packing materials 250, the rotating tube 22 of the regulating mechanism 2 30 passes through the two aerobic packing materials 2 50. The partition 11 divides the inside of the treatment frame 10 into two treatment spaces, one for anaerobic treatment and the other for aerobic treatment. The anaerobic packing material 1 40 and the regulating mechanism 1 20 are located inside the anaerobic treatment space, while the aerobic packing material 2 50 and the regulating mechanism 2 30 are located inside the aerobic treatment space. The regulating mechanism 1 20 and the regulating mechanism 2 30 have the same structure. The regulating mechanism 1 20 includes a fixed plate 21, which is rotatably connected to the rotating tube 22. The bottom end of the rotating tube 22 is connected to a conveying tube 23, and the bottom of the conveying tube 23 is connected to two conveying frames 60. The top of the conveying tube 23 of the regulating mechanism 2 30 is connected to several air outlets 80.

[0023] Specifically, leachate can be introduced into the rotating pipe 22 of the regulating mechanism 20. The leachate can flow out from the conveying frame 60 at the bottom of the conveying pipe 23, thereby transporting the leachate into the anaerobic treatment space. The leachate can flow upward through the interior of the anaerobic packing material 40, and then enter the aerobic treatment space through the top of the partition 11. The aerobic packing material 50 can perform aerobic treatment on the leachate. After treatment, the leachate can flow out from the fixed pipe 13.

[0024] Air can be introduced into the rotating pipe 22 of the regulating mechanism 2 30, so that the air passes through the conveying pipe 23 of the regulating mechanism 2 30 and then floats out from the air outlet 80. This allows the rotating pipe 22 of the regulating mechanism 1 20 and the regulating mechanism 2 30 to rotate relative to the fixed plate 21, causing the rotating pipe 22 to drive the conveying pipe 23 to rotate. This, in turn, causes the conveying frame 60 and the air outlet 80 to rotate within the processing frame 10. In this way, the leachate can be conveyed to the bottom of the two anaerobic packing materials 40 through the conveying frame 60, so that the leachate can fully contact the entire interior of the anaerobic packing materials 40, which is beneficial to the anaerobic treatment of the leachate. Furthermore, the rotation of the stirring plate 90 within the processing frame 10 allows the air to be mixed more evenly in the leachate, which helps to ensure the oxygen content of the leachate in the aerobic zone.

[0025] Example 1

[0026] like Figure 2 As shown, in this embodiment, a partition 2 12 is fixedly connected inside the processing frame 10. There is a certain gap between the bottom surface of the partition 2 12 and the bottom surface of the processing frame 10. The partition 2 12 is located on the side of the partition 11 close to the aerobic packing material 2 50. Two stirring plates 90 are fixedly connected to the bottom of the conveying pipe 23 of the adjusting mechanism 2 30.

[0027] In practice, after the leachate passes the top of partition 11, it enters between partition 11 and partition 2 12. Then, the leachate can enter the bottom of aerobic packing material 2 50 through the bottom of partition 2 12. The leachate can flow upward through the interior of aerobic packing material 2 50. When the conveying pipe 23 of the regulating mechanism 2 30 rotates, it can drive the stirring plate 90 to rotate. This can stir the leachate at the bottom of the aerobic treatment space, so that the leachate is more evenly distributed at the bottom of the two aerobic packing materials 2 50.

[0028] like Figure 3 and Figure 4 As shown, in this embodiment, a drive box 24 that is rotatably connected to the top of the fixed plate 21 is fixedly connected to the top of the rotating tube 22. A connecting tube 25 that is fixedly connected to the top of the rotating tube 22 is rotatably connected to the top of the drive box 24. A drive motor 26 is fixedly connected inside the drive box 24. A drive shaft 27 that is rotatably connected to the output end of the drive motor 26 is driven by the drive shaft 27. Both the drive shaft 27 and the rotating tube 22 are fixedly sleeved with connecting gears 28, and the two connecting gears 28 mesh and drive each other. The fixed plate 21 can position the connecting tube 25 through the drive box 24, and at the same time, it can position the top of the rotating tube 22.

[0029] In specific implementation, leachate can be introduced into the connecting pipe 25 of the regulating mechanism 1 20. The leachate can enter the rotating pipe 22 through the connecting pipe 25. Air can be introduced into the connecting pipe 25 of the regulating mechanism 2 30. The air can enter the rotating pipe 22 of the regulating mechanism 2 30. The drive shaft 27 can be driven to rotate by the drive motor 26. The drive shaft 27 can drive the rotating pipe 22 to rotate through the two connecting gears 28. In turn, the rotating pipe 22 drives the conveying pipe 23 to rotate slowly inside the processing frame 10, so that the leachate is more evenly distributed at the bottom of the two anaerobic packing materials 40 and the air is more evenly mixed in the leachate.

[0030] Example 2

[0031] Based on Example 1, such as Figure 5As shown, in this embodiment, the second adjustment mechanism 30 is provided with a limiting mechanism 70. The limiting mechanism 70 includes a sliding ring 72, which is slidably connected to the rotating tube 22 of the second adjustment mechanism 30. The sliding ring 72 is fixedly connected to two baffles 74, and the baffles 74 are fixedly connected to a triangular plate 75, which is fixedly connected to the sliding ring 72. The triangular plate 75 can limit the end of the baffles 74. The bottom surface of the baffles 74 is connected to the top of the adjacent air outlet 80. The sliding ring 72 is slidably connected to a fixed ring 71, which is fixedly connected to the rotating tube 22 of the second adjustment mechanism 30. The top of the sliding ring 72 is fixedly connected to a return spring 73, which is fixedly connected to the fixed ring 71. The outer edge of the cross-section of the sliding ring 72 can be set to an ellipse, and the inside of the fixed ring 71 can be set to an ellipse. In this way, the fixed ring 71 can prevent the sliding ring 72 from rotating relative to the rotating tube 22 of the second adjustment mechanism 30, so that the sliding ring 72 can only move up or down relative to the rotating tube 22 of the second adjustment mechanism 30.

[0032] In practice, under the action of the return spring 73, the baffle 74 can be attached to the top of several air outlets 80. When air is introduced into the rotating tube 22 of the second adjustment mechanism 30, the air can be blown out from the air outlets 80. At this time, the air can lift the baffle 74, and then the air will float upward. When the air is stopped being introduced into the rotating tube 22 of the second adjustment mechanism 30, under the action of the return spring 73, the baffle 74 can block the corresponding air outlet 80, so as to avoid sludge falling into the air outlet 80.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0034] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
