Description

Technical Field

[0001] This utility model belongs to the field of biological packing technology, and in particular relates to environmentally friendly MBBR biological packing. Background Technology

[0002] MBBR biological packing refers to the biological packing material of a moving bed biofilm reactor. It is a functional material used in the field of wastewater treatment, generally composed of high molecular polymers and other materials. Its special structure and large specific surface area can provide sufficient attachment and growth sites for microorganisms. Inside the reactor, MBBR biological packing is in a fluidized state and moves freely with the water flow and aeration, which promotes full contact between microorganisms, wastewater and oxygen, thereby efficiently carrying out biodegradation reactions and achieving the purpose of removing pollutants such as organic matter, nitrogen and phosphorus from wastewater, significantly improving the efficiency and effect of wastewater treatment.

[0003] Most existing MBBR biological packing materials adopt a flat design with uniformly distributed through holes on their surface for microorganisms to attach. However, the space utilization rate of flat packing materials is limited, and there is still room for improvement in their contact area with sewage. This results in limited contact efficiency between pollutants in sewage and microorganisms on the packing surface, affecting the overall efficiency of sewage treatment. Microorganisms accumulated in the through holes are not conducive to natural renewal and proper shedding, which can easily lead to excessive biofilm thickness, resulting in poor sewage flow, reduced biofilm activity, and weakened long-term stability and purification capacity of the sewage treatment system. Improvements are needed in this regard. Therefore, an environmentally friendly MBBR biological packing material is proposed. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] An environmentally friendly MBBR biological packing material includes vertical rods, on which uniformly distributed arc plates are fixedly installed. Multiple sets of arc plates together form a sphere. There are gaps between the arc plates, and the size of the gaps is the same as the size of the arc plates. Inclined plates are fixedly installed on the outer wall of each arc plate. Both the arc plates and the inclined plates are made of polymer materials.

[0025] In the environmentally friendly MBBR biological packing material, the vertical rods support the entire packing material and stably support multiple sets of arc plates. The arc plates are evenly distributed on the vertical rods and together form a sphere, which expands the surface area of ​​the packing material, facilitates rolling in the sewage, improves the flow effect, and thus improves the contact effect with the sewage.

[0026] The arc plates are spaced apart by the same size as the arc plates, which increases the contact area between the packing and the sewage, allowing the sewage to pass through the packing more fully. When the sewage flows through the packing, it can come into more full contact with the outer and inner surfaces of the arc plates. At the same time, inclined plates are fixedly installed on the outer wall of the arc plates, which further expands the surface area of ​​the packing. Under the combined action of the surface and internal structure of the packing, microorganisms can attach and grow to form a biofilm.

[0027] Meanwhile, due to the spacing between adjacent arc plates, with the spacing size being the same as the arc plate size, space is provided for microorganisms to collide and fall, facilitating natural microbial renewal and moderate shedding, avoiding excessive biofilm thickness and reduced activity, and allowing shed microorganisms to continue participating in wastewater purification, thus enhancing treatment capacity;

[0028] This environmentally friendly MBBR biological packing material not only increases the contact area between the packing material and the sewage, allowing pollutants in the sewage to come into contact with the microorganisms on the surface of the packing material more efficiently, thus improving sewage treatment efficiency, but also, through the surface and internal structure of the packing material, it is conducive to the natural renewal and moderate shedding of microorganisms, effectively avoiding the problem of reduced activity caused by excessive biofilm thickness. The shed microorganisms can also purify the sewage, further enhancing the sewage treatment capacity, making it highly practical.

[0029] The surface of the arc plate has evenly distributed holes;

[0030] The surface of the arc plate has evenly distributed pores, which provide a large number of suitable attachment sites for microorganisms, increase the contact area between microorganisms and sewage, and promote microbial renewal under the action of water flow, so that the biofilm can always maintain high activity and continuously and efficiently treat sewage.

[0031] The surface of the inclined plate has evenly distributed stripes;

[0032] The evenly distributed stripes on the inclined plate surface also create favorable conditions for microbial attachment. During the flow of wastewater, the presence of stripes allows for more thorough contact with microorganisms on the inclined plate surface. The stripes increase the roughness of the inclined plate surface, making it easier and more firmly attached for microorganisms. As microorganisms grow and reproduce at the stripes, the resulting biofilm can better capture pollutants in the wastewater, accelerate the decomposition process, and improve the purification effect on wastewater.

[0033] The vertical rod is fixedly installed with evenly distributed support rods in the middle. The number of support rods is the same as the number of arc plate sets, and the ends of the support rods are fixedly installed to the inner wall of the arc plate.

[0034] Evenly distributed support rods are fixedly installed in the middle of the vertical rods. The number of support rod sets is the same as the number of arc plate sets, and the ends of the support rods are fixedly installed to the inner wall of the arc plate. The support rods play an important role in stabilizing and supporting the arc plate and inclined plate. When water flow impacts the packing, especially when aeration causes significant water disturbance, the support rods can ensure that the arc plate and inclined plate will not deform due to external forces, maintain the overall structural stability of the packing, and promote the continuous growth of microorganisms on the arc plate and inclined plate. This ensures stable contact between sewage and microorganisms, thereby ensuring the efficient and stable operation of sewage treatment.

[0035] The materials of the vertical rods and support rods are the same as those of the arc plate.

[0036] The materials of the vertical rods and supports are the same as those of the arc plates. In wastewater purification, due to the consistent materials, the surfaces of the vertical rods and supports are also suitable for microbial attachment. When wastewater flows between the packing materials, microorganisms not only grow on the arc plates and inclined plates, but also cover the surfaces of the vertical rods and supports, increasing the total number of microorganisms involved in wastewater treatment and further improving the wastewater treatment effect.

[0037] Working principle:

[0038] In the environmentally friendly MBBR biological packing material, the vertical rods support the entire packing material and stably support multiple sets of arc plates. The arc plates are evenly distributed on the vertical rods and together form a sphere, which expands the surface area of ​​the packing material, facilitates rolling in the sewage, improves the flow effect, and thus improves the contact effect with the sewage.

[0039] The arc plates are spaced apart by the same size as the arc plates, which increases the contact area between the packing and the sewage, allowing the sewage to pass through the packing more fully. When the sewage flows through the packing, it can come into more full contact with the outer and inner surfaces of the arc plates. At the same time, inclined plates are fixedly installed on the outer wall of the arc plates, which further expands the surface area of ​​the packing. Under the combined action of the surface and internal structure of the packing, microorganisms can attach and grow to form a biofilm.

[0040] Meanwhile, due to the spacing between adjacent arc plates, with the spacing size being the same as the arc plate size, space is provided for microorganisms to collide and fall, facilitating natural microbial renewal and moderate shedding, avoiding excessive biofilm thickness and reduced activity, and allowing shed microorganisms to continue participating in wastewater purification, thus enhancing treatment capacity;

[0041] This environmentally friendly MBBR biological packing material not only increases the contact area between the packing material and the sewage, allowing pollutants in the sewage to come into contact with the microorganisms on the surface of the packing material more efficiently, thus improving sewage treatment efficiency, but also facilitates the natural renewal and moderate shedding of microorganisms through the surface and internal structure of the packing material. This effectively avoids the problem of reduced activity caused by excessive biofilm thickness. The shed microorganisms can also purify the sewage, further enhancing the sewage treatment capacity and making it highly practical.

[0042] in,

[0043] The surface of the arc plate has evenly distributed pores, which provide a large number of suitable attachment sites for microorganisms, increase the contact area between microorganisms and sewage, and promote microbial renewal under the action of water flow, so that the biofilm can always maintain high activity and continuously and efficiently treat sewage.

[0044] The evenly distributed stripes on the inclined plate surface also create favorable conditions for microbial attachment. During the flow of wastewater, the presence of stripes allows for more thorough contact with microorganisms on the inclined plate surface. The stripes increase the roughness of the inclined plate surface, making it easier and more firmly attached for microorganisms. As microorganisms grow and reproduce at the stripes, the resulting biofilm can better capture pollutants in the wastewater, accelerate the decomposition process, and improve the purification effect on wastewater.

[0045] Evenly distributed support rods are fixedly installed in the middle of the vertical rod. The number of support rod sets is the same as the number of arc plate sets, and the ends of the support rods are fixedly installed to the inner wall of the arc plate. The support rods play an important role in stabilizing and supporting the arc plate and inclined plate. When water flow impacts the packing, especially when aeration causes large water disturbance, the support rods can ensure that the arc plate and inclined plate will not be deformed due to external forces, maintain the overall structural stability of the packing, and promote the continuous growth of microorganisms on the arc plate and inclined plate. This ensures stable contact between sewage and microorganisms, thereby ensuring the efficient and stable operation of sewage treatment.

[0046] The materials of the vertical rods and supports are the same as those of the arc plates. In wastewater purification, due to the consistent materials, the surfaces of the vertical rods and supports are also suitable for microbial attachment. When wastewater flows between the packing materials, microorganisms not only grow on the arc plates and inclined plates, but also cover the surfaces of the vertical rods and supports, increasing the total number of microorganisms involved in wastewater treatment and further improving the wastewater treatment effect.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
