Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a continuous flow aerobic granular sludge reactor. Background Technology

[0002] The activated sludge process is the most widely used biological treatment technology for wastewater in my country's wastewater treatment plants. However, this process has the problem of large footprint, which limits its application. Aerobic granular sludge (AGS) is a compact, regularly shaped microbial aggregate formed by the polymerization of microorganisms under specific conditions. Under physical, chemical, or biological forces, the microorganisms adsorb to each other, secreting extracellular polymers (EPS) to create a biogel effect, forming microbial aggregates. Compared with the traditional activated sludge process, aerobic granular sludge technology has more advantages, including smaller footprint, good settling performance, high biomass concentration, high tolerance to organic loads, and less sludge bulking. It is currently the most promising biological wastewater treatment technology.

[0003] However, most existing continuous flow processes involve operating multiple reactors in series or separating the aeration and sedimentation zones, resulting in poor wastewater treatment performance, large overall footprint, and high costs. Furthermore, some reactors cultivate aerobic granular sludge using biofilms, requiring the addition of biofilm structures inside or outside the reactor. Additionally, the selection of biofilm materials, biofilm formation efficiency, and clogging issues must be considered after implementing biofilms, further increasing equipment and material costs.

[0015] This invention discloses a continuous flow aerobic granular sludge reactor. By designing a sedimentation zone between two reaction zones, granular sludge settles on the two slopes of an inclined plane under gravity. The granular sludge on the slopes can then transfer to the reaction zones on both sides under the shear force of the water flow, thus continuing to participate in the recycling reaction. This combination of the sedimentation zone and the two reaction zones improves the wastewater treatment efficiency and has broad application prospects. Furthermore, when using this reactor to treat wastewater, flocculent sludge can be directly added to the reactor body for cultivation, eliminating the need for a biofilm to cultivate aerobic granular sludge. Therefore, this reactor does not require the addition of internal or external biofilm mechanisms, and thus eliminates concerns about biofilm material selection, biofilm formation efficiency, and clogging. The overall structure is simpler, saving space and reducing costs associated with equipment construction and material replacement. Attached Figure Description

[0042] Example 1

[0043] like Figure 1 As shown, in one embodiment of the present invention, a continuous flow aerobic granular sludge reactor is provided, wherein... Figure 2The L, W, and H directions shown on the coordinate axes represent the length, width, and height directions of the reactor body 10 described below, respectively. This continuous flow aerobic granular sludge reactor includes a reactor body 10, two first baffles 20, and two aeration components 30. Inlet ports 11 are provided on both sides of the reactor body 10, and a ramp 12 is provided at the bottom of the reactor body 10. The ramp 12 has a structure that is raised in the middle and gradually decreases on both sides.

[0044] Two first partition plates 20 are disposed within the reactor body 10 along its height, dividing the inner cavity of the reactor body 10 into a connected sedimentation zone 41 and two reaction zones 42. The sedimentation zone 41 is located above the top of the slope 12 and between the two reaction zones 42, with the sedimentation zone 41 formed between the two first partition plates 20. A first gap 43 is formed between the bottom of the first partition plate 20 and the slope surface of the slope 12, and the sedimentation zone 41 and the reaction zone 42 are connected through the first gap 43. The inlet 11 is connected to the corresponding reaction zone 42, and the aeration assembly 30 is disposed within the corresponding reaction zone 42.

[0045] Flocculent sludge is placed inside the reactor body 10. Wastewater enters the two reaction zones 42 through the inlets 11 on both sides of the reactor body 10. The aeration components 30 provide the necessary oxygen for the reaction. Microorganisms come into contact and collide with each other under the action of gravity or water flow, and after a series of reactions, granular sludge is formed. After the water flows into the sedimentation zone 41 through the first gap 43, the water in the sedimentation zone 41 is more stable than the water in the reaction zone 42 due to the obstruction of the two first baffles 20. Therefore, the granular sludge in the sedimentation zone 41 sinks to the two slopes of the slope 12 under the action of gravity. Due to the aeration of the two aeration components 30, the granular sludge on the slope is transferred to the reaction zones 42 on both sides under the action of water flow shear force. After entering the reaction zones 42, it continues to circulate and react, while the treated wastewater is discharged through the top of the sedimentation zone 41.

[0046] This embodiment provides a continuous flow aerobic granular sludge reactor. By designing a sedimentation zone 41 between two reaction zones 42, the granular sludge settles on both sides of the slope 12 under gravity. The granular sludge on the slope 12 can then transfer to the reaction zones 42 on both sides under the shear force of the water flow, thus continuing to participate in the recycling reaction. In this way, by combining the sedimentation zone 41 with the two reaction zones 42, the treatment effect of wastewater is improved, and it has broad application prospects. Furthermore, when using this reactor to treat wastewater, flocculent sludge can be directly added into the reactor body 10 for cultivation, eliminating the need for a biofilm to cultivate aerobic granular sludge. Therefore, this reactor does not require the addition of internal or external biofilm mechanisms, and there is no need to consider issues such as biofilm material selection, biofilm formation efficiency, and clogging. The overall structure is simpler, saving space and reducing costs associated with equipment construction and material replacement.

[0047] In one embodiment, the reactor further includes two second baffles 50, each second baffle 50 being disposed along the height of the reactor body 10 within a corresponding reaction zone 42. The second baffles 50 divide the reaction zone 42 into a connected first reaction chamber 421 and a second reaction chamber 422, with the second reaction chamber 422 located between the first reaction chamber 421 and the sedimentation zone 41. By adding second baffles 50 within the reaction zone 42, the circulation effect of wastewater and granular sludge within the reaction zone 42 can be effectively improved under aeration, thereby enhancing the wastewater treatment effect.

[0048] Furthermore, a second gap 44 is formed between the bottom of the second partition 50 and the slope surface of the slope 12. The second partition 50 is provided with a water passage hole 51, which is located above the second gap 44. The water inlet 11 is close to the bottom of the first reaction chamber 421, and the aeration assembly 30 is located at the bottom of the first reaction chamber 421 and close to the water inlet 11 and the second gap 44.

[0049] After the wastewater enters the first reaction chamber 421 through the inlet 11, most of the wastewater will flow upward and enter the second reaction chamber 422 through the water passage 51 under the action of aeration. Since the aeration component 30 is close to the second gap 44, a strong water flow shear force will be generated near the second gap 44. In this way, the water in the second reaction chamber 422 will flow into the first reaction chamber 421 through the second gap 44. Furthermore, the aforementioned water flow shear force will also carry the granular sludge on the slope 12 into the second reaction chamber 422 or the first reaction chamber 421, thus further improving the wastewater treatment effect.

[0050] Example 2

[0051] This embodiment includes all the components described in Embodiment 1 above, and their working principles are the same. The difference is that, as shown in the reference... Figure 2-11In this embodiment, a first sealing strip 21 is provided on both sides of the first partition 20, and a second sealing strip 52 is provided on both sides of the second partition 50. Both the first partition 20 and the second partition 50 are movably disposed within the reactor body 10. The reactor also includes a pusher plate 60 and an adjustment drive mechanism 70. The pusher plate 60 is disposed along the height direction of the reactor body 10 and can be attached to the first partition 20 or the second partition 50. The pusher plate 60 is detachably connected to the adjustment drive mechanism 70, which can drive the pusher plate 60 to move along the length direction of the reactor body 10.

[0052] When it is necessary to adjust the distance between the two first partitions 20 (i.e., adjust the size of the sedimentation zone 41 and the reaction zone 42), or to adjust the distance between the two second partitions 50 (i.e., adjust the size of the first reaction chamber 421 and the second reaction chamber 422), by installing the push plate 60 onto the adjustment drive mechanism 70, the adjustment drive mechanism 70 will drive the push plate 60 to move along the length of the reactor body 10. In this way, the first partition 20 or the second partition 50 can be moved, thereby achieving adjustment. At the same time, since the first partition 20 is provided with a first sealing strip 21 on both sides and the second partition 50 is provided with a second sealing strip 52 on both sides, the sealing between the first partition 20 or the second partition 50 and the inner wall of the reactor body 10 can be guaranteed after the position is moved.

[0053] By adjusting the size of the sedimentation zone 41, it is possible to effectively ensure that sludge accumulates as little as possible on the slope 12 at the bottom of the sedimentation zone 41, thereby improving the flow effect of granular sludge. At the same time, sludge with poor settling performance can be conveniently and smoothly discharged from the top of the sedimentation zone 41.

[0054] By adjusting the size of reaction zone 42 and observing the cultivation status of granular sludge during reactor operation, the size of reaction zone 42 can be appropriately increased when the granular sludge cultivation effect is not ideal, allowing more sludge to participate in the reaction. When the granular sludge cultivation effect is good, the size of reaction zone 42 can be appropriately reduced to screen out granular sludge with better settling performance and wastewater treatment capacity.

[0055] Specifically, the adjustment drive mechanism 70 includes a bracket 71, a drive assembly 72 mounted on the bracket 71, and two transverse movement assemblies. The bracket 71 is located on the outer wall of the reactor body 10. The transverse movement assembly includes a lead screw 73, a moving seat 74, and two support seats 75. The two support seats 75 are respectively mounted on the bracket 71. The two ends of the lead screw 73 are rotatably connected to the two support seats 75 respectively. The axis of the lead screw 73 is parallel to the length direction of the reactor body 10. The moving seat 74 is threaded onto the lead screw 73 and slides on the bracket 71 in a direction parallel to the axis of the lead screw 73 (the bottom of the moving seat 74 is provided with a guide block 741, and the bracket is provided with two guide grooves 711, in which the guide block 741 slides within the corresponding guide grooves 711). The drive assembly 72 synchronously drives the two lead screws 73 to rotate. The top of the push plate 60 is provided with a connecting seat 61, and connecting posts 62 are provided on both sides of the connecting seat 61. The moving seat 74 is provided with a plug 76 into which the connecting posts 62 can be inserted.

[0056] The two movable seats 74 are aligned. When it is necessary to adjust the position of the first partition 20 and / or the second partition 50, the two connecting posts 62 of the push plate 60 are inserted into the corresponding inserts 76. This connects the push plate 60 with the two movable seats 74. When the drive assembly 72 is started, it will drive the two lead screws 73 to rotate and move the movable seats 74 and the push plate 60 along the length of the reactor body 10. This will push the first partition 20 or the second partition 50 to move, thereby achieving adjustment.

[0057] After adjusting the positions of the first partition 20 and / or the second partition 50, simply remove the push plate 60. The push plate 60 and the adjusting drive mechanism 70 cooperate with each other, resulting in a simple overall structure, minimal space occupation, and convenient adjustment. Of course, the structure in which the drive assembly 72 simultaneously drives the two lead screws 73 to rotate is existing technology and will not be described in detail in this embodiment.

[0058] Furthermore, a support platform 13 is provided on the outer wall of the reactor body 10, and a bracket 71 is mounted on the support platform 13. The support platform 13 has multiple limiting protrusions 131, and the bracket 71 has multiple limiting holes 712, each limiting hole 712 engaging with a corresponding limiting protrusion 131. The design of the support platform 13 provides good and stable support for the entire adjustment drive mechanism 70. Simultaneously, the interaction between the limiting protrusions 131 and the limiting holes 712 ensures precise alignment of the adjustment drive mechanism 70 and the support platform 13 during assembly.

[0059] In one embodiment, the first partition 20 has two first lugs 22 on each side, the first lugs 22 extending out of the reactor body 10 and having a first limiting block 23. The second partition 50 has two second lugs 53 on each side, the second lugs 53 extending out of the reactor body 10 and having a second limiting block 54. The first limiting block 23 and the second limiting block 54 are both attached to the outer wall of the reactor body 10.

[0060] Since the two first limiting blocks 23 are respectively attached to the outer wall of the reactor body 10, during the process of the pusher plate 60 pushing the first partition 20 to move, the cooperation between the first limiting blocks 23 and the outer wall of the reactor body can effectively prevent the first partition 20 from deflecting, thereby ensuring the sealing between the first partition 20 and the inner wall of the reactor body 10. The second partition 50 can also avoid the above problems, which will not be described in detail here.

[0061] Furthermore, the outer wall of the reactor body 10 is provided with a limiting step 14, and the bottoms of the first limiting block 23 and the second limiting block 54 are both attached to the limiting step 14. The design of the limiting step 14 can provide support for the first limiting block 23 and the second limiting block 54, thus achieving support for the first partition 20 and the second partition 50.

[0062] Based on the above, the working principle of this invention is as follows:

[0063] First, flocculent sludge is placed inside the reactor body 10. The wastewater to be treated enters the two reaction zones 42 through the inlets 11 on both sides of the reactor body 10. The aeration components 30 provide the necessary oxygen for the reaction. Microorganisms come into contact with and collide with each other under the action of gravity or water flow, and after a series of reactions, granular sludge is formed.

[0064] After the water in the reactor body 10 enters the sedimentation zone 41 through the first gap 43, the water in the sedimentation zone 41 is more stable than the water in the reaction zone 42 due to the blocking effect of the two first baffles 20. Therefore, the granular sludge in the sedimentation zone 41 sinks to the two slopes of the slope 12 under the action of gravity. Due to the aeration effect of the two aeration components 30, the granular sludge on the slope is transferred to the reaction zones 42 on both sides under the action of water flow shear force. After entering the reaction zone 42, it continues to circulate and react, while the treated wastewater is discharged through the top of the sedimentation zone 41.

[0065] Meanwhile, during the wastewater treatment process, when it is necessary to adjust the distance between the two first partitions 20 or the distance between the two second partitions 50, the two connecting posts 62 of the push plate 60 are inserted into the corresponding inserts 76. When the drive assembly 72 is started, the drive assembly 72 will drive the two lead screws 73 to rotate and move the moving seat 74 and the push plate 60 along the length of the reactor body 10. In this way, the first partition 20 or the second partition 50 can be moved, thereby achieving adjustment.

[0066] By adjusting the size of the sedimentation zone 41, it is possible to effectively ensure that sludge accumulates as little as possible on the slope 12 at the bottom of the sedimentation zone 41, thereby improving the flow effect of granular sludge. At the same time, sludge with poor settling performance can be conveniently and smoothly discharged from the top of the sedimentation zone 41.

[0067] By adjusting the size of reaction zone 42 and observing the cultivation status of granular sludge during reactor operation, the size of reaction zone 42 can be appropriately increased when the granular sludge cultivation effect is not ideal, allowing more sludge to participate in the reaction. When the granular sludge cultivation effect is good, the size of reaction zone 42 can be appropriately reduced to screen out granular sludge with better settling performance and wastewater treatment capacity.

[0068] Numerous specific details are set forth in this specification. However, it will be understood that embodiments of the invention may be practiced without these specific details. In some instances, well-known methods, structures, and techniques have not been shown in detail so as not to obscure the understanding of this specification.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered within the scope of the claims and specification of the present invention.
