Abstract
Description
Technical Field
[0001] This invention belongs to the field of wastewater treatment technology, and specifically relates to an MBBR packing material. Background Technology
[0002] MBBR is a moving bed bioreactor. When using MBBR for wastewater treatment, suspended media with a density close to that of water are added to the water body to serve as a carrier for microbial attachment and growth. Under the action of aeration or stirring, the suspended media moves with the water flow and is in a fluidized state. The position of the suspended media changes continuously and is distributed throughout the entire water body. The microorganisms attached to the suspended media are distributed throughout the entire water body as the suspended media moves. During the process of microorganisms attaching to the carrier and growing and reproducing, they consume toxic and harmful substances in the wastewater, thereby purifying the wastewater.
[0003] Some existing suspended packing materials have perforated structures. When these materials diffuse and distribute within the water, aeration of the stagnant water provides oxygen to the microorganisms attached to the packing materials, allowing them to grow and reproduce normally. During aeration, the suspended packing materials cut the air bubbles generated, further increasing the oxygen content in the water. The cutting rate is higher when the perforated structure of the packing material faces the rising air bubbles, and lower when the smooth surface faces them. The cutting rate affects the oxygen content of the water, and consequently, the aeration effect. A high cutting rate allows for shorter aeration periods, while a low rate requires longer aeration to maintain adequate dissolved oxygen levels.
[0004] To prevent suspended filler from agglomerating in the water, it is necessary to periodically agitate the water using agitation equipment during use, allowing the suspended filler to disperse and distribute with the disturbance. The movement of suspended filler in the water is complex, involving overturning and shifting. After agitation and settling, the orientation of different suspended fillers changes in the water. Some fillers change from having a perforated structure facing the floating air bubbles to having a smooth surface facing the floating air bubbles, while others change from having a smooth surface facing the floating air bubbles to having a perforated structure facing the floating air bubbles. At this point, compared to before agitation, the shearing rate of the suspended filler on the overall air bubbles in the water changes accordingly. Each time the water is agitated, the shearing rate of the suspended filler on the overall air bubbles in the water changes accordingly.
[0005] Therefore, when aerating water, it is difficult to aerate the water after agitation based on the aeration experience before agitation. After each agitation, it is difficult to control the degree of aeration, resulting in insufficient or excessive aeration, which affects the growth of microorganisms on the suspended packing or leads to high energy consumption. Summary of the Invention
[0006] The technical problem to be solved by the present invention is to provide an MBBR packing material to solve the technical problem that the shearing rate of air bubbles in the water changes after the existing suspended packing material is stirred, making it difficult to control the degree of aeration of the water after each stirring.
[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows:
[0008] An MBBR packing material includes a base and a counterweight disposed within the base; a buoyancy mechanism is provided at the top of the base, and an air bubble splitting mechanism is provided between the base and the buoyancy mechanism.
[0009] Furthermore, the bubble segmentation mechanism includes two winglets located on both sides of the base and symmetrically distributed to each other, and a connecting mechanism embedded in the base and connected between the two winglets; the top of the winglets is connected to the buoyancy mechanism.
[0010] Furthermore, the connecting mechanism includes two U-shaped connecting plates that are parallel to each other, and two rotating rods that are respectively connected between the two connecting plates and respectively connected to the two blades in a one-to-one correspondence and are parallel to each other.
[0011] Furthermore, the connecting plate has a rotating slot adapted to the rotating rod, and both ends of the rotating rod are respectively rotated through the corresponding rotating slot.
[0012] Furthermore, a first mounting groove adapted to the connecting mechanism is provided at the bottom of the base, and the connecting mechanism is mounted in the first mounting groove.
[0013] Furthermore, the buoyancy mechanism includes a connecting rod at the top of the base, a protective shell on the connecting rod, and a buoyancy ball inside the protective shell; the top of the wing is connected to the protective shell.
[0014] Furthermore, the protective shell has an insert cavity adapted to the buoyancy ball, and the buoyancy ball is located in the insert cavity.
[0015] Furthermore, the protective shell has a second mounting groove that matches the top of the wing, and the top of the wing is mounted in the second mounting groove and fixed with bolts.
[0016] Furthermore, an installation cavity is provided inside the base, and a counterweight is located inside the installation cavity. A screw is connected through the counterweight, and both ends of the screw extend out to the two ends of the base. Limiting blocks are threaded to both ends of the screw.
[0017] Furthermore, a permeable groove is provided on the base body that communicates with the installation cavity.
[0018] Compared with the prior art, the present invention has the following beneficial effects:
[0019] This invention features a simple structure, a scientifically sound design, and convenient use. It suspends in water by balancing the weight of the packing material with the buoyancy of the buoyant balls. The invention automatically adjusts its orientation, ensuring that the packing material's position after water agitation matches its position before agitation. This maintains a consistent bubble-cutting rate before and after agitation. Based on this structure, aeration can be performed on the agitated water using experience gained from aeration before agitation. This solves the technical problem of difficulty in controlling the aeration level after each agitation, preventing insufficient or excessive aeration during aeration. It also promotes microbial growth on the suspended packing material and reduces the energy consumption of the aeration equipment. Attached Figure Description

[0039] Example 1
[0040] like Figure 1-14 As shown, the present invention provides an MBBR packing material, including a base 1 and a counterweight 4 disposed in the base 1; a buoyancy mechanism is provided on the top of the base 1, and a bubble splitting mechanism is provided between the base 1 and the buoyancy mechanism.
[0041] This invention features a simple structure, a scientifically sound design, and convenient use. It suspends in water by balancing the weight of the packing material with the buoyancy of the buoyant balls. The invention automatically adjusts its orientation, ensuring that the packing material's position after water agitation matches its position before agitation. This maintains a consistent bubble-cutting rate before and after agitation. Based on this structure, aeration can be performed on the agitated water using experience gained from aeration before agitation. This solves the technical problem of difficulty in controlling the aeration level after each agitation, preventing insufficient or excessive aeration during aeration. It also promotes microbial growth on the suspended packing material and reduces the energy consumption of the aeration equipment.
[0042] The buoyancy ball 2 is located at the top of the base. Due to the buoyancy of the buoyancy ball, before the water is stirred, the packing is distributed in the water with the buoyancy ball on top and the base below. When the water is stirred, the packing is impacted by the water flow and flips or shifts. Due to the buoyancy of the buoyancy ball, the packing automatically adjusts its own position. The end where the buoyancy ball is located gradually moves upward, while the other end of the packing gradually moves downward, until the packing is distributed in the water with the buoyancy ball on top and the base below.
[0043] This invention provides winglets 3 on both sides of the base 1 to increase the force-bearing surface of the packing and improve the balance of the packing in the water. When the water is stirred and the packing is overturned or shifted due to the disturbance of the water flow, the winglets 3 can reduce the degree of overturning or shifting of the packing, which is beneficial for the packing to automatically adjust its own position and restore its original position.

[0047] In this embodiment 2, the vane 3 is used to increase the overall stress-bearing surface of the packing material, and also to break down the floating bubbles. During aeration, the bottom of the seat 1 and the bottom of the vane 3 respectively cut the floating bubbles into more tiny bubbles.

[0062] In this embodiment 5, the rotating rod 7 can rotate between the two connecting plates 6. The wing 3 is fixedly connected to the rotating rod 7, and applying external force to the wing 3 can cause the wing 3 to rotate. When installing the wing 3, first, the connecting mechanism is embedded in the first mounting groove 8, and then the two wing 3 on the connecting mechanism are rotated towards the buoyancy mechanism until the top of the wing 3 is fixedly embedded in the buoyancy mechanism. On the connecting mechanism, a clearance space is formed between the two connecting plates 6 and the two rotating rods 7. The bottom end of the screw 5 extends from the bottom of the base 1 into the clearance space, which facilitates the threaded connection of the limiting block 14 to the bottom end of the screw 5.
