Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and in particular to a sewage treatment device and method for environmental monitoring using high-efficiency activated carbon. Background Art

[0002] High-efficiency activated carbon wastewater treatment equipment, with its superior adsorption performance and recyclability, plays an indispensable role in purifying water containing complex organic matter and some inorganic pollutants. The lifespan of high-efficiency activated carbon is not a fixed value but depends on a variety of factors, including influent quality, pollution load, process design, pretreatment effectiveness, and the application of regeneration technology.

[0003] Generally speaking, in order to ensure the adsorption effect and effluent water quality without regeneration treatment, it is recommended that the cumulative operating time in most industrial applications should not exceed about 500 hours, or be maintained for a maximum of about 3 months under continuous use; once this period is reached, the adsorption capacity of activated carbon tends to decrease significantly, and regeneration or replacement measures need to be taken.

[0004] Publication No. CN117142564B discloses an activated carbon adsorption device, which relates to the field of sewage treatment technology. The device comprises a tube body having an axial flow channel therein, and an activated carbon adsorption module detachably assembled within the axial flow channel. A sealing assembly is provided within the flow channel, the sealing assembly comprising a positioning frame plate, a movable frame plate, and a first drive device sequentially arranged within the axial flow channel along the direction of fluid flow. The outer wall of the positioning frame plate is fixedly connected to the inner wall of the flow channel, the outer wall of the movable frame plate is tightly attached to the inner wall of the flow channel, and the first drive device is used to drive the movable frame plate to slide axially in both directions between a clamping position and an installation position within the flow channel. The present invention, while taking into account sealing requirements and without affecting the sewage treatment effect, enables each activated carbon adsorption assembly to be fully utilized, maximally adsorbing organic pollutants in the sewage, reducing the subsequent treatment cost of the activated carbon and the labor intensity of the staff.

[0005] Although the activated carbon particles themselves have a uniform structure, due to the unidirectional flow of water, the adsorption states on the side facing the water flow and the side facing away from the water flow are usually not exactly the same. The side of the activated carbon facing the water flow directly encounters a high concentration of pollutants, and the adsorption process mainly proceeds rapidly on this surface, so this area is more likely to reach saturation. On the other hand, due to the effect of fluid dynamics and the reduction of local concentration, the side facing away from the water flow has relatively few opportunities to contact pollutants and a lower adsorption load. Although there are a large number of pores in activated carbon that can provide adsorption space, the actual adsorption process depends not only on surface contact, but also on internal diffusion and mass transfer rate. Driven by the water flow, the area facing the water flow forms a concentration gradient due to prior adsorption, prompting the pollutants to gradually diffuse inward, but this diffusion is often limited by the pore mass transfer rate, resulting in a certain difference in the adsorption state between the interior and back areas of the activated carbon and the front. Summary of the Invention

[0006] One of the purposes of the present invention is to provide a sewage treatment device and method for environmental monitoring using high-efficiency activated carbon, which can better utilize high-efficiency activated carbon to complete the treatment of sewage, achieve adsorption of pollutants from multiple directions, and ensure that the problem of inconsistent adsorption states on both sides of the activated carbon due to unidirectional water flow is avoided.

[0029] The above explanation does not fully include the relationship definitions given in this application, but only represents part of it.

[0030] See Figure 1-12 As shown, the present invention provides a sewage treatment device for environmental monitoring using high-efficiency activated carbon, which is used for adsorption treatment of sewage. During the continuous adsorption process, the difference in adsorption states on both sides of the activated carbon can be ensured, so that the activated carbon can be fully used, rather than the problem of inconsistency between the front adsorption state and the back adsorption state, and the need to completely replace the activated carbon when the back is not fully used.

[0031] The sewage treatment plant includes: A treatment chamber 1 for treating sewage, wherein the treatment chamber 1 is provided with an inlet pipe 2 and an outlet pipe 3 and is connected to the inlet pipe 2 and the outlet pipe 3; Among them, the water inlet pipe 2 and the water outlet pipe 3 are both designed with double channels, that is, the water inlet pipe 2 and the water outlet pipe 3 are connected to the two ends of the treatment chamber 1 and are equipped with control valves to control the on-off; A holder 4 is disposed inside the processing chamber 1. A first mounting platform 11 and a second mounting platform 12 are disposed inside the holder 4. The first mounting platform 11 and the second mounting platform 12 are staggered and can swing. When the first mounting platform 11 and the second mounting platform 12 swing to their respective extreme positions, the first mounting platform 11 and the second mounting platform 12 contact each other. A switching member 13 connecting the first mounting platform 11 and the second mounting platform 12 is provided in the middle of the retaining frame 4. When water enters different sides of the processing chamber 1, the switching member 13 controls the first mounting platform 11 and the second mounting platform 12 to switch the front and back of the activated carbon.

[0032] In one practicable embodiment, activated carbon is disposed within the first and second mounting platforms 11, 12. When treating sewage, the first and second mounting platforms 11, 12 can be switched based on the different inlet locations of the sewage at both ends. This allows the front and rear portions of the activated carbon within the first and second mounting platforms 11, 12 to be switched, enabling the use of both the front and rear portions of the activated carbon, greatly improving utilization and service life.

[0033] Among them, since the water inlet pipe 2 and the water outlet pipe 3 are configured at both ends of the processing chamber 1, and the water inlet pipe 2 corresponds to the control of the first mounting platform 11 and the second mounting platform 12, therefore, only one of the two passages of the water inlet pipe 2 can be opened at the same time, while the two passages of the water outlet pipe 3 can be opened simultaneously and separately, and the two passages of the water outlet pipe 3 can be connected to different post-processing ends.

[0034] In one embodiment, the treatment chamber 1 is double-layered to form an inner cavity 14 and an outer cavity 15, the water inlet pipe 2 is connected to the outer cavity 15, and the water outlet pipe 3 is connected to the inner cavity 14. The outer cavity 15 is provided with a plurality of water holes 16 connected to the inner cavity 14, and a screen 17 is provided at the water hole 16 for pre-treating the incoming water.

[0035] In one feasible method, a screen 17 for preliminary treatment of sewage is arranged inside the outer cavity 15. During use, large particles can be intercepted to prevent large particles from entering the inner cavity 14, affecting the adsorption state of the activated carbon and causing blockage of local positions of the activated carbon. The screen 17 can be set to multiple to achieve multiple interceptions of sewage.

[0036] In one embodiment, a cover plate 21 is provided at both ends of the processing chamber 1, and the cover plate 21 is used to seal the processing chamber 1. The blocking net 17 is connected to the cover plate 21 by bolts. After the bolts connecting the blocking net 17 and the cover plate 21 are removed, the blocking net 17 can be removed. A plurality of partitions 23 are provided inside the inner cavity 14 to split the inner cavity 14 into a plurality of processing channels 22. The first mounting platform 11 and the second mounting platform 12 are both provided inside the processing channel 22.

[0037] In one feasible method, the inner cavity 14 is divided into multiple treatment channels 22 by a partition 23, and each treatment channel 22 corresponds to at least one water hole 16. When sewage treatment is performed, each treatment channel 22 can treat the sewage, and the sewage in the water inlet pipe 2 completely enters the outer cavity 15, and enters the inner cavity 14 from the outer cavity 15 to multiple water holes 16.

[0038] Optionally, the blocking nets 17 are connected to the cover plate 21 and contact one side of the processing chamber 1. In this state, multiple blocking nets 17 are connected to the cover plate 21 by bolts. When the connection between the cover plate 21 and the processing chamber 1 is removed, all the blocking nets 17 can be removed through the cover plate 21. When all the bolts between the cover plate 21 and the blocking nets 17 are removed, the cover plate 21 can be removed and a single blocking net 17 can be removed.

[0039] In another embodiment, the blocking net 17 extends to the outside of the cover plate 21 and is connected by bolts. In this connection state, the connecting bolts between the blocking net 17 and the cover plate 21 can be removed separately, so that the blocking net 17 can be removed to facilitate cleaning and replacement.

[0040] In one embodiment, the water inlet pipe 2 is connected to the cover plate 21, a drive chamber 24 is provided on the inner side of the cover plate 21, a roller 25 is arranged inside the drive chamber 24, a rotating shaft 26 is provided in the middle of the roller 25, and the rotating shaft 26 extends to the inner chamber 14 and is connected to the switching member 13, the drive chamber 24 is connected to the outer chamber 15, and the rollers 25 on both sides rotate in opposite directions.

[0041] In one feasible method, since the water inlet pipe 2 has its own flow characteristics when driving water into the treatment chamber 1, the flow of the sewage itself is used to drive the roller 25 to rotate, thereby determining the position of the water inlet, so as to achieve mechanical judgment of the switching state. The rotation directions of the rollers 25 at both ends are inconsistent. Therefore, during the rotation of the shaft 26, the switching member 13 can be driven to switch the first mounting platform 11 and the second mounting platform 12 to different states.

[0042] In one embodiment, the retaining frame 4 extends between the first mounting platform 11, the second mounting platform 12 and the partition 23, and the first mounting platform 11 and the second mounting platform 12 are both located between the partition 23 and are respectively connected to the two side walls of the processing channel 22. A connecting piece is configured between the first mounting platform 11 and the second mounting platform 12 to connect with the retaining frame 4. The switching piece 13 includes at least one retaining ring 31 for sealing the gap between the partition 23 and the retaining frame 4. A connecting frame 32 is configured on the outside of the retaining ring 31 to extend to the inside of the retaining frame 4 and be connected to the connecting piece.

[0043] In one feasible method, the first mounting platform 11 and the second mounting platform 12 are firmly connected to the retaining frame 4 through a connecting piece, and are connected to the connecting piece through the connecting frame 32. When the state of the first mounting platform 11 and the second mounting platform 12 needs to be changed, the switching piece 13 changes the state of the connecting piece through the connecting frame 32, so that the first mounting platform 11 and the second mounting platform 12 move, thereby realizing the adjustment of the activated carbon.

[0044] In one embodiment, a first push rod 35 and a second push rod 36 are disposed within the retaining ring 31 and extend through the connecting frame 32 to the outside of the connecting frame 32. A collar 33 is disposed on a portion of the first and second push rods 35 and 36 extending toward the central axis of the inner cavity 14. The collar 33 is sleeved on the outer side of the rotating shaft 26, and a damping member 34 is disposed between the collar 33 and the rotating shaft 26. The first push rod 35 and the second push rod 36 are arranged up and down, and a section of the first push rod 35 and the second push rod extending toward the damping member 34 is an engaging protrusion 37. A limiting groove 38 is provided on the outside of the ring 33. When the engaging protrusion 37 is embedded in the limiting groove 38, the ring 33 is limited.

[0045] In one practicable manner, the positions of the first mounting platform 11 and the second mounting platform 12 are adjusted by adjusting the positions of the first push rod 35 and the second push rod 36. In order to allow the rollers 25 on both sides to rotate in different directions, the rotating shaft 26 can drive the rings 33 at different positions to rotate through the damping member 34, so that the first push rod 35 or the second push rod 36 extends outward to change the position of the first mounting platform 11 and the second mounting platform 12. The meshing setting between the first push rod 35, the second push rod 36 and the ring 33 plays the role of ratchet cooperation, and only pushes the first push rod 35 or the second push rod 36 to move during the rotation process.

[0046] In one embodiment, the damping member 34 is elastically configured, a spring structure is configured inside the rotating shaft 26, a ball 39 is configured at one end of the spring structure extending outward from the rotating shaft 26, a pit is configured at a corresponding position on the inner wall of the ring 33, and the ball 39 cooperates with the pit, and a support spring 310 is configured at one end of the first push rod 35 and the second push rod 36 extending to the outside of the connecting frame 32 so that the first push rod 35 and the second push rod 36 contact the ring 33.

[0047] In one practicable manner, the spring structure provides stable resistance under the cooperation of the ball 39 and the pit. During the rotation of the shaft 26, the ring 33 can rotate along with the shaft 26. When the first push rod 35 or the second push rod 36 restricts the ring 33, the rotation of the shaft 26 cooperates with the ring 33 to squeeze the ball 39, causing the spring structure to be compressed, thereby limiting the rotation of one of the rings 33, and the first push rod 35 or the second push rod 36 corresponding to the ring 33 will not be pushed outward.

[0048] With this design, when the roller 25 drives the rotation in one direction, the collar 33 in the other direction is stably restricted. Thus, the first push rod 35 and the second push rod 36 can only move individually, ensuring the stable position of the first mounting platform 11 and the second mounting platform 12.

[0049] In one embodiment, the connector includes: The mounting head 41 is fixed to the bottom of the first mounting platform 11 and the second mounting platform 12, and extends through the retainer 4 to between the retainer 4 and the partition 23; The meshing gear 42 is sleeved on the outside of the mounting head 41. The meshing gear 42 is arranged up and down and corresponds to the first push rod 35 and the second push rod 36. The meshing frame 43 is disposed outside the meshing gear 42 and when the first push rod 35 and the second push rod 36 push the meshing frame 43 to move, the meshing frame 43 meshes with the meshing gear 42 for transmission. When the meshing frame 43 pushes different meshing gears 42 to rotate, the directions are opposite.

[0050] In one practicable manner, the first push rod 35 and the second push rod 36 are each correspondingly configured with an engaging frame 43 and an engaging gear 42. When the first push rod 35 or the second push rod 36 is pushed outward by the ring 33, the engaging frame 43 moves with the movement of the first push rod 35 or the second push rod 36. The engaging frame 43 drives the engaging gear 42 to rotate, causing the first mounting platform 11 and the second mounting platform 12 to rotate, thereby switching the front and back of the activated carbon.

[0051] Among them, when the meshing frame 43 is not pushed by the first push rod 35 or the second push rod 36, it does not contact the meshing gear 42 and remains stationary, avoiding motion interference caused by the other meshing frame 43 during movement, and further ensuring the movement stability of the meshing gear 44. The rotation accuracy of the meshing gear 42 and the flexible response of the meshing frame 43 ensure the smooth switching of the first mounting platform 11 and the second mounting platform 12.

[0052] In one embodiment, a compression spring 311 is configured at one end of the engagement frame 43 away from the first push rod 35 and the second push rod 36. The compression spring 311 supports the engagement frame 43. The support spring 310 is located between the engagement frame 43 and the first push rod 35 or the second push rod 36 and contacts the two. The elastic force of the support spring 310 is greater than that of the compression spring 311, and the elastic force is greater than the friction between the engagement frame 43 and the engagement gear 42.

[0053] In one practicable manner, through the cooperation of the support spring 310 and the compression spring 311, when the first push rod 35 or the second push rod 36 pushes the engagement frame 43, the compression spring 311 will be compressed first, and the support spring 310 will then provide additional resistance to ensure stable movement of the engagement frame 43, avoid damage to the engagement gear 42 due to instantaneous excessive force, and maintain the balance and precision of the overall structure.

[0054] When resetting by the compression spring 311 and the support spring 310, the first push rod 35 or the second push rod 36 will first move closer to the collar 33 under the action of the support spring 310. At this time, the engagement frame 43 will not move. Therefore, even if the shaft 26 drives the collar 33 to rotate continuously, when the first push rod 35 or the second push rod 36 enters the limiting groove 38 of the collar 33, the engagement frame 43 still remains stationary. During the continuous rotation of the collar 33, the engagement frame 43 is always stable.

[0055] In one embodiment, each group of the first mounting platform 11 and the second mounting platform 12 constitutes an adsorption unit, and each group of the first mounting platform 11 and the second mounting platform 12 moves synchronously. A meshing wheel 44 is provided at the bottom of the first mounting platform 11 and the second mounting platform 12 for meshing transmission. When the first push rod 35 or the second push rod 36 pushes the meshing gear to rotate through the meshing frame 43, the first mounting platform 11 and the second mounting platform 12 rotate synchronously. The rotation range of the first mounting platform 11 and the second mounting platform 12 is 180° and when located at the two extreme positions of the rotation range, the first mounting platform 11 and the second mounting platform 12 are in contact.

[0056] In one feasible method, through the precise design of the meshing gear 42, it is ensured that each rotation angle is accurate to 1°, thereby achieving efficient switching of the activated carbon, switching the front and back of the activated carbon, ensuring the continuity and stability of the adsorption effect, extending the service life of the activated carbon, and improving the working efficiency and reliability of the overall device.

[0057] The present application also provides a sewage treatment method, which is used in the above-mentioned sewage treatment device, comprising the following steps: The sewage enters the treatment chamber 1 through the water inlet pipe 2 and is based on the sewage inlet end; Determine the switching state of the switching element 13 based on the sewage inlet end; The first mounting platform 11 and the second mounting platform 12 are switched between the front and the back based on the switching member 13; The adsorbed sewage enters the middle of the treatment chamber 1 and is discharged through the outlet pipe 3.

[0058] Although the present invention is disclosed in conjunction with the above embodiments, it is not intended to limit the present invention. Anyone familiar with this technology can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the definition of the attached claims.
