Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a biological packing support structure for a microbial attached wastewater MABR treatment device. Background Technology

[0002] In the field of wastewater treatment, MABR (membrane bioreactor) technology has gained widespread application and attention due to its high wastewater treatment capacity and low energy consumption. As the carrier for microbial attachment and growth in MABR treatment equipment, the rationality of the supporting structure of the biological packing directly affects the microbial living environment, the contact efficiency between wastewater and the biological packing, and thus determines the wastewater treatment effect.

[0003] Currently, flexible biological packing materials are commonly used in existing technologies to facilitate the installation and replacement of biological packing materials. These materials are usually equipped with locking hooks, which generally consist of a hook body and a movable locking component. The hook body is used to connect with the support structure, while the locking component can firmly fix the end of the flexible biological packing material through elastic deformation or mechanical snapping, preventing the biological packing material from detaching from the hook during sewage flow.

[0004] However, existing biological packing support structures often have many problems when adapting to flexible biological packing with locking hooks: the structure of the biological packing support components is fixed, making it difficult to adjust the installation spacing according to different specifications of biological packing, resulting in poor versatility. Furthermore, the installation and replacement of biological packing require the disassembly of a large number of parts, making the operation cumbersome and the maintenance inefficient. Therefore, we propose a biological packing support structure for a microbial attached wastewater MABR treatment equipment. Utility Model Content

[0005] The purpose of this invention is to provide a biological packing support structure for a microbial attached wastewater MABR treatment device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A biological packing support structure for a microbial attachment wastewater MABR treatment device includes a treatment tank. The treatment tank has side plates on both sides. One side plate has an inlet at its bottom for introducing wastewater to be treated, and the other side plate has an outlet at its bottom for discharging treated wastewater. The bottom of the treatment tank's interior has multiple bottom baffles to guide wastewater flow. A top baffle is located at the top of the treatment tank, between the bottom baffles. The bottom baffles and the top baffle cooperate to extend the flow path of wastewater within the tank. Multiple sets of biological packing support components are located inside the treatment tank, between the bottom and top baffles, to stably support the biological packing and ensure a suitable environment for microbial attachment.

[0008] As a preferred embodiment of this utility model, the top ends of the multiple bottom partitions and the bottom ends of the top partitions are not connected to the equipment processing box, and a flow port is formed between them. This flow port can guide the sewage to form a baffle between the bottom partitions and the top partitions, thereby prolonging the contact time between the sewage and the biological packing material.

[0009] As a preferred embodiment of this utility model, the multiple sets of biological filler support components include support frames fixed inside the equipment processing box on both sides and the bottom. Insertion track grooves are provided on both sides and the bottom of the inner surface of the support frame, and an installation frame is inserted into the support frame.

[0010] As a preferred embodiment of this utility model, the top and bottom of the mounting frame are respectively provided with an upper base and a lower base, and both the bottom of the upper base and the bottom of the lower base are provided with sliding grooves, and both the front of the upper base and the lower base are provided with communicating grooves that communicate with the sliding grooves.

[0011] As a preferred embodiment of this utility model, multiple connecting seats are slidably connected in the chute. Each of the multiple connecting seats extends a connecting groove at one end of its front side and is threaded with a fastening bolt. Each of the multiple connecting seats extends from the top of the chute and is connected with an installation ring. The upper and lower installation rings are used to connect to the locking hooks on the flexible biological packing material.

[0012] As a preferred embodiment of this utility model, the inner back of the slide groove is provided with a fixing groove for fastening bolts to lock and abut against it.

[0013] As a preferred embodiment of this utility model, the mounting frame is provided with plug-in blocks that are adapted to the plug-in track groove on both sides and the bottom, the mounting frame is provided with handles on the top, and the top of the equipment processing box is provided with multiple slots that are adapted to the top plate of the mounting frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this invention, the biological filler support assembly includes a support frame, a connecting track groove, and an installation frame. The support frame provides a fixed foundation for the assembly, the connecting track groove enables precise guidance and quick insertion of the installation frame, and the installation frame can be removed entirely from the support frame. At the same time, with the cooperation of the connecting track groove and the connecting blocks on both sides and the bottom of the installation frame, the installation frame is ensured to be smoothly inserted into the support frame, which facilitates the batch installation, replacement, and maintenance of the biological filler and reduces the difficulty of operation.

[0016] Furthermore, through the design of the sliding grooves and connecting grooves opened in the upper and lower bases within the installation frame, as well as the sliding connection seats, fastening bolts on the connecting seats, and installation rings within the sliding grooves, the sliding grooves allow the connecting seats to flexibly adjust their positions to adapt to the installation gap distribution of different specifications of biological packing materials. The connecting grooves provide a channel for the operation of the fastening bolts, and the installation rings can be connected to the locking hooks of the biological packing materials. At the same time, with the cooperation of the fastening bolts and the fixing grooves on the back of the sliding grooves, the connecting seats can be firmly fixed, preventing them from shifting under the impact of water flow. This enables the rapid connection, disassembly, and stable installation of the biological packing materials, ensuring a stable environment required for microbial attachment.

[0017] In this invention, the design of the handle on the top of the mounting frame provides a convenient point of force for inserting and removing the mounting frame. At the same time, with the cooperation of the handle and the slot on the top of the equipment processing box, the operator can quickly take the mounting frame out of or into the slot. Combined with the guiding effect of the insertion track slot and the insertion block, the efficiency of maintenance and replacement of biological packing is greatly improved and the maintenance cost is reduced.

[0028] Example

[0029] like Figures 1-5As shown, this utility model provides a technical solution: a biological packing support structure for a microbial attachment wastewater MABR treatment device, including a treatment tank 1. The treatment tank 1 has side plates 101 on both sides. One side plate 101 has an inlet 2 at its bottom for introducing wastewater to be treated, and the other side plate 101 has an outlet 201 at its bottom for discharging treated wastewater. The bottom of the treatment tank 1 has multiple bottom partitions 3 for guiding wastewater flow. A top partition 301 is located at the top of the treatment tank 1, between the multiple bottom partitions 3. The bottom partitions 3 and the top partition 301 cooperate to extend the flow path of wastewater within the tank. Multiple sets of biological packing support components 4 are located inside the treatment tank 1, between the bottom partitions 3 and the top partition 301, for stabilizing and supporting the biological packing and ensuring a suitable environment for microbial attachment.

[0030] The top ends of multiple bottom baffles 3 and the bottom ends of top baffles 301 are not connected to the equipment treatment box 1. A flow port 302 is formed between them. The design of the flow port 302 breaks the closed state of the bottom baffles 3 and top baffles 301, guides the sewage to form a baffle, and changes the straight flow mode of the sewage. The baffle phenomenon directly prolongs the residence time of sewage in the equipment, thereby increasing the contact time between sewage and biological packing, allowing microorganisms more time to decompose pollutants in sewage.

[0031] The multi-group biological filler support assembly 4 includes support frames 401 fixed inside the equipment processing box 1 on both sides and the bottom. The inner surface of the support frame 401 has insertion track grooves 4011 on both sides and the bottom. An installation frame 402 is inserted into the support frame 401. The support frame 401 provides a fixed foundation for the entire biological filler support assembly 4, ensuring the stability of the structure under the impact of water flow. The insertion track grooves 4011 provide precise installation guidance for the installation frame 402, which facilitates the quick positioning and insertion of the installation frame 402. As the direct load-bearing structure of the biological filler, the installation frame 402 can be removed as a whole from the support frame 401, which facilitates the batch installation, replacement and maintenance of the biological filler.

[0032] The mounting frame 402 has an upper base 403 at the top and a lower base 404 at the bottom. The bottom of the upper base 403 and the bottom of the lower base 404 are both provided with sliding grooves 405. The front of the upper base 403 and the lower base 404 are both provided with connecting grooves 406 that communicate with the sliding grooves 405. The upper base 403 and the lower base 404 provide an installation platform for the connecting components of the biological packing. The sliding grooves 405 provide space for the sliding adjustment of the connecting seat 407, which can be distributed according to the installation gap of the biological packing and flexibly change the position of the connecting seat 407. The connecting grooves 406 provide a channel for the operation of the fastening bolts 408, which facilitates fixing after the position of the connecting seat 407 is adjusted.

[0033] Multiple connecting seats 407 are slidably connected within the chute 405. Each connecting seat 407 has a connecting groove 406 extending from one end of its front side, threaded with a fastening bolt 408. Each connecting seat 407 has an installation ring 409 extending from the top of the chute 405. The upper and lower installation rings 409 are used to connect to the locking hooks on the flexible biological packing. The connecting seats 407 can be adjusted in position by sliding within the chute 405 to meet the installation requirements of biological packing of different specifications. The fastening bolts 408 can firmly fix the connecting seats 407 within the chute 405 to prevent them from shifting under the impact of water flow. The installation rings 409 cooperate with the locking hooks of the biological packing to achieve quick connection and disassembly of the biological packing, and the connection is stable, ensuring that the biological packing does not fall off during equipment operation.

[0034] The inner back of the slide groove 405 is provided with a fixing groove 4010 for locking the fastening bolt 408. The fixing groove 4010 provides a dedicated abutment position for the fastening bolt 408. When the fastening bolt 408 is locked, its end is embedded in the fixing groove 4010, which increases the contact area and friction between the bolt and the slide groove 405, making the fixing of the connecting seat 407 more secure and reliable, and preventing the connecting seat 407 from shifting due to the loosening of the bolt caused by water flow vibration.

[0035] The mounting frame 402 has plug-in blocks 4021 on both sides and bottom that are compatible with the plug-in rail grooves 4011. The top of the mounting frame 402 is equipped with handles 4022. The top of the equipment handling box 1 has multiple slots 5 that are compatible with the top plate of the mounting frame 402. The plug-in blocks 4021 are precisely matched with the plug-in rail grooves 4011 to ensure that the mounting frame 402 can be inserted into the support frame 401 smoothly and accurately, ensuring the sealing and stability of the structural connection. The handles 4022 provide a force point for the insertion and removal of the mounting frame 402, making it convenient for operators to quickly remove or put into the mounting frame 402 and reducing the difficulty of maintenance.

[0036] The working process of this utility model is as follows: When using a biological packing support structure for a microbial attached wastewater MABR treatment device, the wastewater to be treated first enters the device through the inlet 2 at the bottom of the side plate 101 on one side of the treatment tank 1. At this time, the treatment tank 1, as the core load-bearing structure, provides a closed reaction space for wastewater treatment. The side plates 101 on both sides play the role of sealing and fixing the inlet 2 and outlet 201. After the wastewater enters, it begins to flow under the guidance of multiple bottom baffles 3 at the bottom of the treatment tank 1. The bottom baffles 3 initially regulate the flow direction of the wastewater, laying the foundation for the subsequent formation of baffles.

[0037] As the sewage continues to flow, since the tops of the multiple bottom baffles 3 and the bottoms of the top baffles 301 are not connected to the equipment treatment tank 1, the flow port 302 formed between them begins to function. The flow port 302 guides the sewage to form a baffle between the bottom baffles 3 and the top baffles 301, breaking the straight flow pattern of the sewage. This baffle phenomenon prolongs the residence time of the sewage in the equipment, allowing the sewage to fully contact the biological packing material on the biological packing material support assembly 4 in the area between the bottom baffles 3 and the top baffles 301. At the same time, the cooperation between the bottom baffles 3 and the top baffles 301 further prolongs the flow path of the sewage in the tank, ensuring that the sewage has a longer contact time with the biological packing material, creating favorable conditions for microorganisms to decompose pollutants.

[0038] In the area between the bottom partition 3 and the top partition 301, multiple sets of biological packing support components 4 begin to function stably. Among them, the support frame 401, which is fixed inside the equipment treatment box 1 on both sides and the bottom, provides a stable foundation for the entire component, ensuring that the structure will not shake under the impact of water flow. The insertion track groove 4011 in the support frame 401 ensures the accurate positioning and stable insertion of the installation frame 402. The installation frame 402, as the direct load-bearing structure of the biological packing, fixes the flexible biological packing through components such as the upper base 403, lower base 404, connecting seat 407, and installation ring 409.

[0039] The upper base 403 and lower base 404 within the mounting frame 402 provide an installation platform for the connecting seat 407. The connecting seat 407 can slide and adjust its position within the slide groove 405. The operator operates the fastening bolt 408 through the connecting groove 406 to fix the connecting seat 407 in a suitable position. At this time, the fixing groove 4010 on the back of the slide groove 405 allows the fastening bolt 408 to firmly abut against it, preventing the connecting seat 407 from shifting under the impact of water flow. The mounting ring 409 at the top of the connecting seat 407 is connected to the locking hook on the biological packing, achieving stable installation of the biological packing and ensuring a stable environment required for microbial attachment. During the flow deflection process, the sewage comes into full contact with the biological packing, and the microorganisms on the biological packing utilize the pollutants in the sewage for metabolic activities, thereby achieving sewage purification.

[0040] When maintenance or replacement of the biological packing material is required, the operator can remove the mounting frame 402 from the slot 5 at the top of the equipment processing box 1 using the handle 4022 on the top of the mounting frame 402. The plug-in blocks 4021 on both sides and the bottom of the mounting frame 402 are compatible with the plug-in track groove 4011 in the support frame 401, allowing the mounting frame 402 to be pulled out of the support frame 401 smoothly and easily, reducing the difficulty of operation. After removing the mounting frame 402, the fastening bolts 408 on the connecting seat 407 can be loosened, the position of the connecting seat 407 can be adjusted, or the biological packing material can be replaced. Then, the mounting frame 402 can be reinserted into the support frame 401 through the cooperation of the plug-in blocks 4021 and the plug-in track groove 4011 to complete the maintenance or replacement work. During this process, the guiding effect of the plug-in track groove 4011 and the labor-saving design of the handle 4022 greatly improve the maintenance efficiency.

[0041] After thorough purification, the wastewater flows to the outlet 201 at the bottom of the side plate 101 on the other side of the equipment treatment tank 1 under the baffle effect, and is discharged from the equipment through the outlet 201. During this process, the baffle design ensures full contact between the wastewater and the biological packing material, and the biological packing material support component 4 ensures the stability of the biological packing material and the activity of microorganisms, so that pollutants in the wastewater are effectively removed, and the wastewater discharged in the end meets the treatment requirements.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
