Description

Technical Field

[0001] The utility model relates to the technical field of sewage and wastewater treatment, in particular to an MBR membrane treatment device with ultrafiltration membrane filaments placed horizontally. Background Art

[0002] Wastewater treatment refers to the process of treating urban drainage and domestic and industrial sewage to prevent water pollution and ensure environmental safety. The MBR membrane treatment method is to filter out stains in sewage through a filter membrane to achieve the purpose of purification.

[0003] However, it still has the following disadvantages in actual use:

[0004] Existing MBR sewage treatment usually adopts the vertical placement of membrane fiber groups. Because there is a water collection pipe at the bottom, the aeration at the bottom cannot effectively enter the gaps between the membrane fibers, which hinders the efficiency of aeration and sludge removal. As a result, sludge is easily accumulated between the membrane fibers after long-term use, resulting in serious membrane pollution and a significant decrease in water production. Utility Model Content

[0005] The purpose of the present invention is to provide an MBR membrane treatment device with horizontally placed ultrafiltration membrane filaments, so as to solve the problem raised in the above background technology that the existing MBR sewage treatment usually adopts a vertical placement of membrane filament membrane groups, because there is a water collection pipeline at the bottom, which causes the aeration at the bottom to be unable to effectively enter between the membrane filaments, hindering the efficiency of aeration and sludge removal, resulting in sludge accumulation between the membrane filaments after long-term use, causing serious membrane pollution and a significant decrease in water production.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The utility model is an MBR membrane treatment device with ultrafiltration membrane filaments placed horizontally, comprising:

[0008] A sewage and wastewater treatment unit, comprising a first mounting frame, a second mounting frame, an ultrafiltration membrane, and an aerator;

[0009] A second mounting frame is arranged on one side of the first mounting frame, and the end of the ultrafiltration membrane is threaded on the inner middle of the first mounting frame and the second mounting frame. The aerator is arranged at the lower end of the ultrafiltration membrane, and the ultrafiltration membrane is arranged horizontally.

[0010] Furthermore, a threaded hole extending into the end of the ultrafiltration membrane is formed through the middle of the upper end of the first mounting bracket and the second mounting bracket.

[0011] Furthermore, it also includes a stabilizing portion, which includes a sleeve and a stabilizing seat;

[0012] The sleeves are fixed to the outer edge of the bottom end of the aerator at equal distances, and the stabilizing seat is sleeved on the lower end of the sleeves.

[0013] Compared with the prior art, the advantages of the present invention are:

[0014] The utility model arranges the ultrafiltration membrane horizontally and arranges an aerator underneath. Aeration is generated by the controlled operation of the aerator and acts on the ultrafiltration membrane above, thereby achieving the effect of aeration and sludge removal and maintaining the long-term, efficient and stable treatment effect of the ultrafiltration membrane.

[0024] See also Figure 1-3 As shown, this embodiment is an MBR membrane treatment device with ultrafiltration membrane filaments placed horizontally, comprising:

[0025] The sewage and wastewater treatment unit includes a first mounting frame 11, a second mounting frame 12, an ultrafiltration membrane 13, and an aerator 14;

[0026] A second mounting frame 12 is arranged on one side of the first mounting frame 11, and the end of the ultrafiltration membrane 13 is threaded on the inner middle part of the first mounting frame 11 and the second mounting frame 12. The aerator 14 is arranged at one end below the ultrafiltration membrane 13, and the ultrafiltration membrane 13 is arranged horizontally.

[0027] The first mounting frame 11 and the second mounting frame 12 are used to install the ultrafiltration membrane 13. The ultrafiltration membrane 13 filters and purifies the wastewater. The aerator 14 acts on the ultrafiltration membrane 13 by generating aeration, which can be used to treat the sludge and improve the use effect.

[0028] A threaded hole extending into the end of the ultrafiltration membrane 13 is formed through the middle of the upper end of the first mounting frame 11 and the second mounting frame 12;

[0029] Insert the external screws into the threaded holes and tighten them, and the ultrafiltration membrane 13 can be installed on the inner side of the first mounting frame 11 and the second mounting frame 12. The threaded connection method is convenient for structural disassembly and assembly;

[0030] It also includes a stabilizing portion, which includes a sleeve 21 and a stabilizing seat 22;

[0031] The sleeve 21 is fixed to the outer edge of the bottom end of the aerator 14 at equal distances, and the fixing seat 22 is sleeved on the lower end of the sleeve 21;

[0032] The sleeve 21 is used to install the structure of the stabilizing seat 22, and the contact between the stabilizing seat 22 and the contact surface provides structural stability to the aerator 14;

[0033] Working principle: After placing the ultrafiltration membrane 13 in the middle of the first mounting frame 11 and the second mounting frame 12, insert a screw into the threaded hole and tighten it so that the thread at the lower end of the screw extends into the threaded hole at the end of the ultrafiltration membrane 13;

[0034] At this time, a plurality of aerators 14 are evenly spaced at one end below the ultrafiltration membrane 13. When the wastewater is filtered and purified by the ultrafiltration membrane 13, aeration acts on the ultrafiltration membrane 13 to flush and remove the sludge.

[0035] This solution can achieve the effect of aeration and sludge removal, and maintain long-term, efficient and stable treatment of the ultrafiltration membrane 13.
