Description

Technical Field

[0001] The utility model relates to the technical field of wastewater, in particular to an MBR membrane integrated wastewater treatment device. Background Art

[0002] Sponge city is a new generation of urban stormwater management concept, which means that the city can adapt to environmental changes and respond to natural disasters caused by rainwater like a sponge, with good flexibility. Specifically, rainwater is collected through urban pipes, and then filtered and treated, and finally discharged into storage pools for subsequent use. For rainwater collection modules in residential areas, the treated rainwater is expected to be used for residents' daily water use, which places higher requirements on rainwater filtration.

[0003] In the field of sewage treatment and water resource reuse, MBR membrane, also known as membrane bioreactor, is a new water treatment technology that combines a membrane separation unit with a biological treatment unit. It mainly uses microporous filtration membrane to filter rainwater so that rainwater can be reused. The use of ultrafiltration membrane filtration not only saves the treatment process of the water plant, but also has low cost. MBR ultrafiltration membrane is a porous material that removes impurities in the water by physical interception. Therefore, after a period of use, its micropores are easily blocked and affect the filtration effect. The frequent disassembly and cleaning process is cumbersome and costly. In view of this, we propose an MBR membrane integrated wastewater treatment equipment. Utility Model Content

[0031] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0032] The present invention will be further described below with reference to the embodiments.

[0033] Example: Refer to the attached Figure 1-6As shown in the figure, an MBR membrane integrated wastewater treatment equipment includes a tank body 100, the upper and lower ends of the tank body 100 are provided with openings, and a cavity 101 is opened in the tank body 100; and a moving rod 200 movably connected in the tank body 100, the upper end of the moving rod 200 is fixedly installed with a cover body 210, the inner wall of the cavity 101 is fixedly installed with a guide plate 400, the lower end of the moving rod 200 is fixedly installed with a cylindrical member 220, and the lower side of the cylindrical member 220 is rotatably connected with a lap ring 300; it also includes a mounting ring 500 fixedly installed inside the cavity 101 and located at the lower side of the guide plate 400, a filter membrane 520 is provided between the mounting ring 500 and the middle part of the cylindrical member 220, and the inner wall of the filter membrane 520 is fixedly connected to the outer wall of the lower side of the cylindrical member 220. Specifically, during actual use, the opening located on the upper side of the tank body 100 is used to inject the sewage to be treated from the upper side of the tank body 100. The sewage entering the cavity 101 passes through the guide plate 400 and enters the filter membrane 520. Under the action of gravity, the sewage can be filtered and discharged from the opening on the lower side of the tank body 100.

[0034] Preferably, the guide plate 400 is a circular disc with a raised center, and is provided with a plurality of circulation slots 401 at equal intervals in a circular pattern. A through-hole 402 is provided in the center of the guide plate 400, the inner wall of which slides with the outer wall of the cylindrical member 220. When sewage is injected into the cavity 101 through the opening on the upper side of the tank body 100, the cover 210 fixedly mounted on the upper end of the movable rod 200 guides the sewage and causes it to fall into the circulation slots 401 on the guide plate 400. The sewage that falls through the circulation slots 401 then falls onto the filter membrane 520, where it is filtered.

[0035] In order to improve the filtering effect of the filter membrane 520 and to avoid the filter membrane 520 from being blocked after a period of use, in the present application, an external cylinder is used to drive the movable rod 200 to move back and forth in the vertical direction. Furthermore, an arc groove 221 is provided on the outer wall of the cylindrical member 220, and the arc groove 221 slides with the guide rod 410 fixedly installed on the inner wall of the through hole 402; when the movable rod 200 moves vertically upward under the action of the cylinder, the guide rod 410 slides in the arc groove 221, driving the cylindrical member 220 to rotate and thereby driving the filter membrane 520 to twist. When the cylinder drives the movable rod 200 to move upward, combined with the fixed connection between the movable rod 200 and the cylindrical member 220, the corresponding cylindrical member 220 will also move upward synchronously. Combined with the sliding fit between the guide rod 410 and the arc groove 221, since the guide rod 410, the guide plate 400 and the tank body 100 maintain a fixed connection, when the movable rod 200 moves upward, the corresponding cylindrical member 220 will also rotate relatively. When the cylindrical member 220 rotates, due to the fixed connection between the filter membrane 520 connected to the cylindrical member 220, the corresponding filter membrane 520 will be twisted and wrinkled. In this case, the through hole on the filter membrane 520 will increase, which can effectively avoid the problem of the through hole on the filter membrane 520 being blocked and affecting the filtering effect after a period of use.

[0036] Preferably, a storage chamber 223 is defined within the lower portion of the cylindrical member 220. The lower end of the storage chamber 223 is fixedly connected to the output of an external water pump via a connecting tube 240. Multiple inclined tubes 230 are evenly connected to the outer walls of the storage chamber 223, with the outlets of the inclined tubes 230 aligned with the lower outer wall of the filter membrane 520. A contact sensor 320 is fixedly mounted on the upper end of the lap ring 300. A capsule 310 is located between the lap ring 300 and the guide plate 400 and communicates with a connecting hole 222 defined within the cylindrical member 220 via a curved tube 311. The connecting hole 222 communicates with the storage chamber 223 and contains a control valve. When the movable rod 200 drives the cylindrical member 220 upward, the capsule 310 is compressed, causing the gas stored within the capsule 310 to overflow from the inclined tubes 230 and be blown toward the lower outer wall of the filter membrane 520.

[0037] Preferably, a plurality of collecting holes 501 are evenly opened on the mounting ring 500, and the lower side of the collecting hole 501 is connected to the external collecting tank through the inner wall of the tank body 100 via a hose 510. When the external cylinder drives the movable rod 200 to move upward, the corresponding capsule 310 set on the lap ring 300 will be compressed, and the gas in the corresponding capsule 310 will enter the storage chamber 223. When the movable rod 200 moves to the uppermost position, the contact sensor 320 set on the lap ring 300 will contact the lower side of the guide plate 400. At this time, the movable rod 200 moves upward. The rod 200 stops moving upward, and the control valve provided on the connecting pipe 240 will open. The output end of the external water pump will inject liquid into the storage chamber 223. It should be noted that at this time, the filter membrane 520 is in an inclined state with the middle part bulging upward. When the liquid rushes towards the filter membrane 520, the liquid will clean the impurities on the filter membrane 520 to ensure the filtering effect of the filter membrane 520. The liquid overflowing to the upper side of the filter membrane 520 will flow into the collection hole 501 along the inclined filter membrane 520 and be discharged into the collection tank through the hose 510.

[0038] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the various embodiments of the present invention.
