MBR, also known as membrane bioreactor, is a novel water treatment technology combining activated sludge method and membrane separation technology. When treating industrial wastewater, it has good effluent quality, small floor area and energy saving.

A first connection block is connected to the lower side inside the MBR tank, and an MBR membrane connection block is snap-connected above the first connection block. A fourth valve is arranged on the lower right side of the MBR tank, and the fourth valve is connected to the MBR tank through a double-pass water pipe. The blower is connected to the MBR membrane connection block through a double-pass water pipe, and a first valve is arranged on the left side of the blower, and the first valve is located on the right side of the MBR tank. The upper and lower sides of the MBR membrane sheets are both provided with MBR membrane connection blocks. This countercurrent MBR wastewater treatment equipment realizes the complete separation of the sludge retention time and the hydraulic retention time through the MBR membrane sheets, makes the sludge decomposition more complete, and through hydraulic backwashing, makes the sludge and water fully mixed, which is beneficial to the formation of larger zoogloea. And it is provided with a support frame and a spring, saving space and playing a role in shock absorption and reducing noise.

[0004] In order to solve the problems of MBR industrial wastewater treatment, the existing technology is to adopt the method of realizing the complete separation of the sludge retention time and the hydraulic retention time through MBR membrane sheets to make the sludge decomposition more complete. However, there will still be situations where the MBR membrane sheets are not convenient to disassemble and the filter screen is not cleaned sufficiently, which leads to the inconvenience of replacing the MBR membrane sheets and the inability to effectively clean the filter screen, resulting in the problem of insufficient practicality of the equipment. Summary of the Invention

[0005] The purpose of the utility model is to provide a novel MBR industrial wastewater treatment equipment to solve the problems put forward in the above background technique.

[0006] To solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A novel MBR industrial wastewater treatment equipment, including a water tank, a filter screen is installed inside the water tank, a cleaning mechanism is installed on the surface of the filter screen, an aeration tank is installed on one side of the water tank, and an MBR membrane filtration mechanism is installed inside the aeration tank;

[0008] The MBR membrane filtration mechanism includes fixing bolts, which are threadedly connected to both sides of the aeration tank. An assembly component is threadedly connected to the surface of the fixing bolts, and an MBR membrane is installed on the surface of the assembly component. An aeration pipe penetrates through the surface of the MBR membrane.

[0009] A further improvement of the technical solution of the present utility model lies in that: the assembly component includes a cross plate and a notch. The cross plate is threadedly connected to the surface of the fixing bolt. A threaded groove is formed on the surface of the cross plate.

[0011] A further improvement of the technical solution of the present utility model lies in that: the cleaning mechanism includes a motor, which is fixedly connected to the water tank. The output end of the motor is fixedly connected to a transmission shaft. The transmission shaft, and a linkage block is threadedly connected to the surface of the transmission shaft. There are two linkage blocks, and the motor drives the transmission shaft to rotate.

[0012] A further improvement of the technical solution of the present utility model lies in that: a limit post is slidably connected to the surface of the linkage block, and the limit post is used to limit the linkage block.

[0013] A further improvement of the technical solution of the present utility model lies in that: the limit post and the transmission shaft are fixedly connected inside the installation frame. One end of the linkage block is fixedly connected to a connection plate, and a cleaning brush is fixedly connected to the surface of the connection plate.

[0015] Due to the adoption of the above technical solution, the technical progress obtained by the present utility model compared with the prior art is:

[0016] The utility model provides a novel MBR industrial wastewater treatment device. The air diffuser is inserted into the MBR membrane, and water passes through the MBR membrane and is further filtered by the MBR membrane. When the MBR membrane needs to be replaced, the fixing bolt is rotated, and the fixing bolt disengages from the outside of the aeration tank.

Detailed Description of the Specific Embodiment

[0024] The following further elaborates on the utility model in conjunction with the embodiments: Embodiment

[0025] As Figures 1 - 5 shown, the utility model provides a new type of MBR industrial wastewater treatment device, which includes a water tank 1. A filter screen 3 is installed inside the water tank 1. A cleaning mechanism 2 is installed on the surface of the filter screen 3. An aeration tank 4 is installed on one side of the water tank 1. An MBR membrane filtration mechanism 5 is installed inside the aeration tank 4. The MBR membrane filtration mechanism 5 includes fixing bolts 51. The fixing bolts 51 are threadedly connected to both sides of the aeration tank 4. An assembly component 50 is threadedly connected to the surface of the fixing bolts 51. An MBR membrane 52 is installed on the surface of the assembly component 50. An air pipe 53 penetrates through the surface of the MBR membrane 52. The assembly component 50 includes a cross plate 501 and a notch 505. The cross plate 501 is threadedly connected to the surface of the fixing bolts 51. A threaded groove 502 is formed on the surface of the cross plate 501. The notches 505 are formed on both sides of the MBR membrane 52. A connecting groove 506 is formed inside the notches 505. One side of the cross plate 501 is fixedly connected with a stabilizing block 503. One end of the stabilizing block 503 is fixedly connected with a connecting block 504;

[0026] Specifically, the air pipe 53 penetrates into the MBR membrane 52. Water passes through the MBR membrane 52 and is filtered again through the MBR membrane 52. When the MBR membrane 52 needs to be replaced, the fixing bolts 51 are rotated. The fixing bolts 51 are disengaged from the outside of the aeration tank 4. Then the cross plate 501 is pulled. The cross plate 501 drives the stabilizing block 503 and the connecting block 504 to disengage from the notch 505 and the connecting groove 506, so that the MBR membrane 52 is disengaged from the fixation, thus facilitating the flexible fixation and disassembly of the MBR membrane 52. Embodiment

[0027] As Figures 1 - 5 shown, on the basis of Embodiment 1, the utility model provides a technical solution: Preferably, the cleaning mechanism 2 includes a motor 20. The motor 20 is fixedly connected to the water tank 1. The output end of the motor 20 is fixedly connected with a transmission shaft 21. The transmission shaft 21 is threadedly connected with two linkage blocks 23 on its surface. The linkage blocks 23 are slidably connected with limiting columns 22 on their surfaces. The limiting columns 22 and the transmission shaft 21 are fixedly connected inside an installation frame 26. One end of the linkage block 23 is fixedly connected with a connecting plate 24. A cleaning brush 25 is fixedly connected to the surface of the connecting plate 24. The cleaning brush 25 includes a movable sleeve shaft 250. The movable sleeve shaft 250 is fixedly connected to the bottom of the connecting plate 24. An movable column 251 is movably connected inside the movable sleeve shaft 250. One end of the movable column 251 is fixedly connected with a brush body 252;

[0028] Specifically, preliminary filtration is carried out through the filter screen 3. The motor 20 drives the transmission shaft 21 to rotate, so that the transmission shaft 21 drives the connecting plate 24 on the linkage block 23 to move reciprocally. When the connecting plate 24 moves reciprocally, the linkage block 23 is limited by the limit post 22. The connecting plate 24 drives the cleaning brush 25 to move reciprocally. When the cleaning brush 25 moves for cleaning, the movable column 251 on the brush body 252 is driven by the frictional force to rotate inside the movable sleeve shaft 250, so as to strengthen the cleaning of the filter screen 3.

[0029] Next, the working principle of the new MBR industrial wastewater treatment device will be specifically described.

[0030] As Figures 1 - 5 shown, preliminary filtration is carried out through the filter screen 3. The motor 20 drives the transmission shaft 21 to rotate, so that the transmission shaft 21 drives the connecting plate 24 on the linkage block 23 to move reciprocally. When the connecting plate 24 moves reciprocally, the linkage block 23 is limited by the limit post 22. The connecting plate 24 drives the cleaning brush 25 to move reciprocally. When the cleaning brush 25 moves for cleaning, the movable column 251 on the brush body 252 is driven by the frictional force to rotate inside the movable sleeve shaft 250, so as to strengthen the cleaning of the filter screen 3. The air diffuser pipe 53 penetrates into the MBR membrane 52, and the water passes through the MBR membrane 52 for secondary filtration. When the MBR membrane 52 needs to be replaced, the fixing bolt 51 is rotated, and the fixing bolt 51 disengages from the outside of the aeration tank 4. Then, the cross plate 501 is pulled, and the cross plate 501 drives the stabilizing block 503 and the connecting block 504 to disengage from the notch 505 and the connecting groove 506, so that the MBR membrane 52 is disengaged from the fixation, thus facilitating the flexible fixation and disassembly of the MBR membrane 52.

However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art.
