[0002] Membrane bioreactor is a water treatment technology that combines membrane separation unit with biological treatment unit.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-8 A membrane bioreactor for sewage treatment includes a membrane bioreactor body 1 and a membrane material assembly 2, the upper and lower sides of the membrane material assembly 2 are both provided with mounting ends 21, the membrane bioreactor body 1 is adapted to be provided with mounting holes 11 corresponding to the mounting ends 21, and the membrane bioreactor body 1 is fixedly provided with lower reinforcing plates 3 below the mounting holes 11. A removable upper reinforcing plate 31 is mounted on the top of the lower reinforcing plate 3, and a slot is adapted to be provided on the lower reinforcing plate 3 and the upper reinforcing plate 4 corresponding to the mounting ends 21. It is worth noting that the device only provides reinforcing support for the membrane material assembly 2 after installation. The installation of the membrane material assembly 2 can be achieved by assembling the mounting end 21 in the mounting hole 11. The specific structure of the mounting hole 11 and the mounting end 21 and the installation method thereof are all existing technologies currently disclosed on the market, which are all common knowledge known to those skilled in the art, and do not belong to the main technical problems to be solved in the present technical solution, so they are not elaborated in the present utility model.

[0024] Among them, a plurality of positioning columns 32 are fixed vertically downward at the bottom of the upper reinforcing plate 31, and corresponding positioning columns 32 on the lower reinforcing plate 3 are adapted to open positioning cavities 33. Through the adaptation of the positioning columns 32 and the positioning cavities 33, the upper reinforcing plate 31 can be positioned when it is installed.

[0025] Among them, the top of the lower reinforcing plate 3 is fixedly provided with a fixing seat 5 on both sides of the upper reinforcing plate 31, and an anti-dropping cavity 51 is provided in the fixing seat 5. Both ends of the upper reinforcing plate 31 are provided with a limiting hole 34, and a detachable limiting column 4 is adapted and inserted in the limiting hole 34. An anti-dropping piece 42 is fixedly provided on the outside of the limiting column 4, and the diameter of the limiting column 4 is the same as the diameter of the anti-dropping cavity 51. By setting the anti-dropping piece 42 and the anti-dropping cavity 51, the limiting column 4 can be prevented from falling off when being clamped.

[0026] Among them, a fixing cavity 41 is vertically penetrated on the limiting column 4, a detachable movable column 6 is inserted in the fixing cavity 41, a handle 61 is fixedly provided on the top of the movable column 6, and a fixing hole 63 is adapted to be opened on the lower reinforcing plate 3 corresponding to the movable column 6. The fixing of the limiting column 4 can be realized by the adaptation and clamping between the movable column 6, the fixing cavity 41 and the fixing hole 63.

[0027] Among them, the membrane bioreactor body 1 is fixedly provided with a mounting seat 7 corresponding to the movable column 6, and the mounting seat 7 is fixedly provided with a clamping piece 71, and the movable column 6 is adapted to be vertically provided with a clamping slot 62 corresponding to the clamping piece 71. The clamping piece 71 is located in the clamping slot 62, and the clamping piece 71 is fixedly provided. The clamping between the clamping slot 62 and the clamping piece 71 can prevent the movable column 6 from falling off during the upward and downward movement.

[0028] In the present embodiment, sewage treatment can be achieved by setting up the membrane bioreactor body 1 and the membrane material assembly 2, and the specific structure of the membrane bioreactor body 1 and the membrane material assembly 2 and the installation method are both existing technologies currently disclosed on the market. They are all common knowledge well known to technical personnel in this field, and are not the main technical problems to be solved in this technical solution. Therefore, they are not elaborated in this utility model.

[0029] Furthermore, the user can assemble the membrane material assembly 2 on the mounting hole 11 through the mounting end 21, and the specific assembly methods are all prior art. At this time, the mounting end 21 of the membrane material assembly 2 is located above the lower reinforcing plate 3, and the user only needs to assemble the upper reinforcing plate 31 above the lower reinforcing plate 3, so as to achieve the reinforcement and fixation of the mounting end 21.

[0030] Furthermore, when the user needs to assemble the upper reinforcing plate 31, the user only needs to insert the positioning posts 32 at the bottom of the upper reinforcing plate 31 into the positioning cavity 33 in the lower reinforcing plate 3. Then, the limiting posts 4 on both sides are pushed into the limiting holes 34 in the upper reinforcing plate 31, so that the upper reinforcing plate 31 can be clamped.

[0031] Furthermore, the user only needs to move the movable column 6 downward so that the positioning column 6 passes through the fixing cavity 41 and is inserted into the fixing hole 63, thereby the limiting column 4 can be clamped by the movable column 6. And because the positioning column 6 is arranged vertically, its own gravity can prevent it from falling off from the fixing hole 63.

[0032] Furthermore, the anti-dropping member 42 and the anti-dropping cavity 51 can prevent the limiting column 4 from dropping during the clamping process, and the matching clamping between the clamping slot 62 and the clamping member 71 can prevent the movable column 6 from dropping during the upward and downward movement.

[0033] In the utility model, sewage treatment can be achieved through the arrangement of the membrane bioreactor body 1 and the membrane material assembly 2. The membrane material assembly 2 can be reinforced and fixed after installation through the arrangement of the lower reinforcing plate 3 and the upper reinforcing plate 31, thereby ensuring the stability of the membrane material assembly 2 during operation and preventing it from loosening, thereby further improving the sewage treatment efficiency of the membrane bioreactor body 1.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
