Description

Technical Field

[0001] This utility model relates to the field of biological treatment device technology, and in particular to an anaerobic MBR biological treatment device. Background Technology

[0002] Against the backdrop of increasingly severe water scarcity and water pollution, efficient and stable wastewater treatment technologies have become one of the core research directions in the environmental protection field. Anaerobic membrane bioreactors, as a novel wastewater treatment process integrating anaerobic biological treatment and membrane separation technologies, are widely used in the treatment of various types of wastewater, including industrial wastewater and domestic sewage, due to their advantages such as low energy consumption, low sludge production, high pollutant removal rate, and the ability to recover resources (such as methane). They have particularly demonstrated significant application value in the treatment of high-concentration organic wastewater.

[0003] In practical applications, existing biological treatment devices have relatively complete structures and functions, which can meet basic usage requirements, but the following problems still exist:

[0004] During the collection and transportation of industrial or domestic wastewater, larger particles such as sand, suspended solids, and fibrous impurities are often mixed in. These larger particles tend to accumulate on the flow guiding structure and the surface of the biological carrier within the treatment frame, disrupting the living environment of anaerobic microorganisms and reducing their degradation activity for organic pollutants. Furthermore, particulate matter may physically rub against subsequent membrane separation components, causing scratches on the membrane surface and breakage of membrane fibers, thus shortening the lifespan of the filter membrane. Additionally, some wastewater does not remain in the treatment frame for an sufficient time; organic pollutants and toxic substances are not fully decomposed by anaerobic microorganisms before being rapidly carried by the water flow to the surface of the filter membrane frame and filtered out, further reducing the overall treatment efficiency.

[0005] Therefore, this utility model provides an anaerobic MBR biological treatment device. Utility Model Content

[0040] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] This embodiment provides a technical solution: such as Figures 1-5As shown, this embodiment of the present invention provides an anaerobic MBR biological treatment device, comprising a treatment frame 1, a partition plate 2, a detachable filter assembly 3, a barrier filter assembly 4, and a mixing assembly 5. The treatment frame 1 has a cuboid structure and serves as the main housing component of the entire device. The partition plate 2 is fixedly connected to the inner wall of the treatment frame 1 to divide the internal space of the treatment frame 1, thereby optimizing the water flow path and treatment process. The detachable filter assembly 3 is located on the top of the treatment frame 1 and includes a rectangular ring groove 31, a rectangular ring block 32, and a filter screen 36.

The filter screen 36 is fixedly connected to the inner wall of the rectangular ring block 32, performing preliminary filtration of the wastewater entering the treatment frame 1 to prevent larger particles from entering. The barrier filter assembly 4 is located on top of the partition plate 2 and includes a U-shaped frame 43, a hydraulic telescopic rod 44, an auxiliary plate 45, a barrier baffle 46, and a limiting rod 47.

The auxiliary plate 45 is fixedly connected to the output end of the hydraulic telescopic rod 44, transmitting the power of the hydraulic telescopic rod 44. The barrier baffle 46 is fixedly connected to the bottom of the auxiliary plate 45 and can be raised and lowered by the hydraulic telescopic rod 44 to prevent harmful substances in the sewage from flowing to the filter membrane frame 49 before complete decomposition. The limiting rod 47 is fixedly connected to the top of the auxiliary plate 45 and slidably located on top of the U-shaped frame 43, limiting and guiding the lifting and lowering movement of the auxiliary plate 45. The mixing assembly 5 is located inside the treatment frame 1 to promote thorough mixing of sewage and microorganisms, improving treatment efficiency.

[0042] By disassembling and assembling filter component 3, large particulate impurities in wastewater can be filtered to avoid affecting the decomposition and subsequent filtration processes.

[0045] like Figure 3 As shown, a sealing block 39 is snapped into the inner wall of the discharge chute 38 to seal the discharge chute 38 during normal operation. A rectangular baffle 310 is fixedly connected to one side of the sealing block 39. A third screw hole 311 is opened on one side of the rectangular ring plate 37, and a fourth screw hole 312 is opened on one side of the rectangular baffle 310. The third screw hole 311 and the fourth screw hole 312 are threadedly connected by a second threaded clamp 313 to ensure that the sealing block 39 securely seals the discharge chute 38.

[0046] like Figure 2 and Figure 4 As shown, the inner wall of the partition plate 2 has a rectangular slot 42, into which the baffle plate 46 can be inserted to achieve precise control of the sewage flow direction. The inner wall of the partition plate 2 also has a water outlet trough 41, which is used to guide the treated water to the subsequent treatment unit.

[0047] like Figure 2 and Figure 5 As shown, a rectangular slot 48 is provided on one side of the partition plate 2. A filter membrane frame 49 is fitted into the inner wall of the rectangular slot 48. The filter membrane frame 49 contains a hollow fiber membrane made of PVDF material with a pore size of 0.1μm for deep filtration of wastewater. A fifth screw hole 410 is provided on one side of the rectangular slot 48, and a sixth screw hole 411 is provided on one side of the filter membrane frame 49. The fifth screw hole 410 and the sixth screw hole 411 are connected by a third threaded rod 412 to ensure that the filter membrane frame 49 is installed securely.

[0048] like Figure 1 and Figure 5 As shown, the mixing assembly 5 includes a U-shaped plate 51, with a drive motor 52 mounted on one side of the U-shaped plate 51. A drive rod 53 is fixedly connected to the output end of the drive motor 52, and a driven rod 54 is rotatably connected to one side of the U-shaped plate 51. A spiral blade rod 58 is fixedly connected to one end of both the drive rod 53 and the driven rod 54. The drive motor 52 drives the drive rod 53 and the spiral blade rod 58 to rotate, and the transmission structure drives the driven rod 54 and the corresponding spiral blade rod 58 to rotate, thus achieving the mixing of wastewater within the treatment frame 1.

[0049] like Figure 5As shown, a drive pulley 55 is fixedly connected to the outer surface of the drive rod 53, and a driven pulley 56 is fixedly connected to the outer surface of the driven rod 54. A transmission belt 57 is provided on the outer surfaces of the drive pulley 55 and the driven pulley 56. Through the transmission structure composed of the drive pulley 55, the driven pulley 56 and the transmission belt 57, the power transmission from the drive rod 53 to the driven rod 54 is realized.

[0050] Working principle:

[0051] like Figure 1-5 As shown:

[0052] In use, the rectangular ring clamping block 32 is engaged with the rectangular ring clamping groove 31. At this time, the first threaded clamping rod 35 is rotated and fixed with the first screw hole 33 and the second screw hole 34, so that the filter screen plate 36 can be installed. When it is necessary to clean the impurities on the filter screen plate 36, the second threaded clamping rod 313 is separated from the third screw hole 311 and the fourth screw hole 312, so that the sealing block 39 can be disassembled, and the impurities can be taken out from the discharge chute 38.

[0053] The filter membrane frame 49 is snapped into the rectangular slot 48, and the third threaded rod 412 is fixed to the fifth screw hole 410 and the sixth screw hole 411. When the sewage is still decomposing, the hydraulic telescopic rod 44 is activated so that the auxiliary plate 45 can drive the baffle 46 to move, which can then cooperate with the rectangular slot 42 to block the outlet tank 41.

[0054] After the wastewater is filtered by the filter membrane frame 49, disinfectant is added to the filtered wastewater. At this time, the drive motor 52 is started, so that the drive rod 53 can drive the drive pulley 55 to rotate, which in turn drives the transmission belt 57 and the driven pulley 56 to rotate, which in turn drives the driven rod 54 to rotate, causing the two spiral blade rods 58 to rotate, thereby stirring and mixing the disinfectant and wastewater.

[0055] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
