Description

Technical Field

[0001] This utility model relates to the field of MBBR packing technology, and in particular to a portable MBBR packing module. Background Technology

[0002] MBBR packing is a key component used in moving bed biofilm reactors to provide a large surface area for the growth and attachment of microorganisms.

[0003] Currently, an existing MBBR packing structure, disclosed in publication number (CN210885481 U), includes a packing body with a columnar structure. The packing body has a central hexagonal cross-section, and multiple packing rings are formed around the central hexagon. Each packing ring consists of 6n regular hexagons, where n is the number of rings closest to the central hexagon. The outermost packing rings have anti-adhesion protrusions. This invention prevents the MBBR packing material from adhering to each other, thus avoiding the loss of effective surface area. Furthermore, the MBBR is designed with multiple hexagonal (cross-section) rings, further increasing the surface area of ​​the MBBR packing and enhancing biofilm adhesion, thereby improving wastewater treatment efficiency.

[0004] During the implementation of the existing technical solution, at least the following technical problems were found:

[0005] The existing MBBR packing has a fixed structure. When multiple MBBR packings are transported, they are stacked together and many gaps are generated. This occupies a large amount of transport space, but the transport volume is not large, resulting in problems such as difficulty in transportation and poor portability. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a portable MBBR packing module, solving the problems of existing MBBR packings being difficult to transport and having poor portability.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A portable MBBR packing module includes an MBBR module comprising eleven packing bodies, each of which is fixedly connected to a first polymer connector and a second polymer connector.

[0009] Preferably, the surface of the packing body has nineteen hexagonal through holes.

[0010] Preferably, the inner walls of each hexagonal through-hole in the filler body are coated with a cationic polymer coating, which is a chitosan coating.

[0011] Preferably, the outer wall of the filler body is coated with a hydrophilic polymer, which is a PDA coating.

[0012] Preferred: The hexagonal through hole is hexagonal.

[0013] Preferably, the filler body is made of polyvinyl chloride.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] I. In this application, the entire packing body is connected in series by a first polymer connector and a second polymer connector, and the whole is composed of a hexagonal structure. During transportation, the edges of each packing body can be directly brought together, reducing the gaps between them and making it easy to transport. At the same time, when only a few packing bodies are needed, one MBBR module can be held with one hand. The design of the first and second polymer connectors allows workers to hold twenty-two packing bodies with both hands. If workers hug the MBBR modules, they can hold six to twelve MBBR modules at a time. That is to say, workers can transport sixty-six to one hundred and ten packing bodies without using any tools, making this application easy to transport.

[0016] II. In practical use, each of the first or second polymer connectors can be torn off as needed. Simply hold the two packing bodies with both hands and pull hard to break off the first or second polymer connectors. Alternatively, this application can be used directly in the filtration system of a fishpond or swimming pool without breaking off the first or second polymer connectors. Or, each of the first or second polymer connectors can be torn off to make each packing body a single unit for use in a moving bed biofilm reactor, making this application highly applicable.

[0024] This application provides a portable MBBR packing module, which effectively solves the problems of existing MBBR packings being difficult to transport and having poor portability.

[0025] Example

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the technical solution in this embodiment effectively solves the technical problems of existing MBBR packings being difficult to transport and having poor portability. The overall idea is as follows:

[0027] To address the problems existing in the prior art, this utility model provides a portable MBBR packing module, including an MBBR module 1. The MBBR module 1 includes eleven packing bodies 2, and each packing body 2 is fixedly connected to a first polymer connector 202 and a second polymer connector 203.

[0028] Nineteen hexagonal through holes 201 are opened on the surface of the packing body 2.

[0029] The inner walls of each hexagonal through-hole 201 in the filler body 2 are coated with a cationic polymer coating 3, which is a chitosan coating.

[0030] The outer wall of the filler body 2 is coated with hydrophilic polymer 4, which is a PDA coating.

[0031] The hexagonal through hole 201 is hexagonal in shape.

[0032] The packing body 2 is made of polyvinyl chloride, and the second polymer connector 203 and the first polymer connector 202 are made of the same material as the packing body 2.

[0033] MBBR Module 1: As a whole unit, multiple packing bodies 2 are connected into a detachable and combinable system, which facilitates batch transportation and installation and can adapt to filtration needs of different scales.

[0034] Packing body 2: Provides the main structure for microbial attachment, and increases the specific surface area through hexagonal through-holes 201 to promote biofilm formation and contact reaction with pollutants.

[0035] Cationic polymer coating 3: Coated on the inner wall of hexagonal through-hole 201, utilizing the positive charge properties of chitosan to adsorb negatively charged microorganisms, accelerating biofilm formation and inhibiting harmful bacteria, thereby improving treatment efficiency.

[0036] Hydrophilic polymer 4: Covers the outer wall of the packing body 2, enhances the contact with sewage through the hydrophilicity of the PDA coating, and prevents the packing material from sticking together, thus maintaining fluidization performance.

[0037] Hexagonal through-hole 201: Arranged in regular hexagonal shapes, it optimizes water flow distribution and turbulence, increases the surface area for microbial attachment, and reduces the weight of the packing material, thus reducing energy consumption.

[0038] The first polymer connector 202 is a thin sheet made of polyvinyl chloride, which serves to connect the filler body 2 in series, maintain structural stability during transportation, and can be manually torn apart to adjust the module shape during use, thus achieving modular disassembly.

[0039] Second polymer connector 203: Works in conjunction with first polymer connector 202 to strengthen the structural strength of the module, support multi-angle folding and deformation, and adapt to different filtration system spaces.

[0040] Working principle:

[0041] In the first step, in this application, the entire filler body 2 is connected in series by the first polymer connector 202 and the second polymer connector 203, and the whole is composed of a hexagonal structure. During transportation, the edges of each filler body 2 can be directly brought together, reducing the gaps between them and making it easy to transport. At the same time, when only a few filler bodies 2 are needed, one MBBR module 1 can be held with one hand. The arrangement of the first polymer connector 202 and the second polymer connector 203 allows the worker to hold twenty-two filler bodies 2 with both hands. If the worker hugs the MBBR module 1, six to twelve MBBR modules 1 can be held at once. That is to say, the worker can transport sixty-six to one hundred and ten filler bodies 2 without using any tools, so that this application has the effect of facilitating transportation.

[0042] Secondly, in actual use, each of the first polymer connectors 202 or the second polymer connectors 203 can be torn off as needed. Simply hold both packing bodies 2 with both hands and pull hard to break off the first polymer connectors 202 or the second polymer connectors 203. Alternatively, this application can be used directly in the filtration system of a fishpond or swimming pool without breaking off the first polymer connectors 202 or the second polymer connectors 203. Alternatively, each of the first polymer connectors 202 or the second polymer connectors 203 can be torn off so that each packing body 2 becomes a separate unit and is used in a moving bed biofilm reactor. Alternatively, only the first polymer connectors 202 or the second polymer connectors 203 can be torn off so that the MBBR module 1 can be folded into a circle. This gives this application the effect of being deformable and adaptable to the internal space of different filtration systems.

[0043] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
