[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0018] like Figure 1 - Figure 12 As shown, the present invention provides: An automated membrane filtration water treatment device includes an anaerobic tank 10 and an anoxic tank 20 installed on one side of the anaerobic tank 10, with an MBR tank 30 provided on one side of the anoxic tank 20. The MBR tank 30 is equipped with an MBR membrane unit 40. The MBR membrane unit 40 includes a mounting frame 41 and an MBR membrane module 42 mounted on the mounting frame 41. Preferably, the MBR membrane module 42 is a hollow fiber membrane. The MBR membrane unit 40 also includes an aeration component fixed to the bottom of the mounting frame 41. A product water pipe is installed on the MBR membrane module 42, and a water collection pipe connected to the product water pipe is mounted on the mounting frame 41. Specifically, after being treated in anaerobic tank 10 and facultative tank 20, the wastewater is sent to MBR tank 30 for further treatment. During water production, under pressure or suction, water permeates from the outside of the membrane to the inside (the lumen of the hollow fiber membrane), and then flows through the permeate pipe into the collection pipe for discharge, thus achieving solid-liquid separation. The aeration device generates bubbles in the tank, creating shear force to remove pollutants from the membrane surface and control membrane fouling.

[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 10 As shown, a tension adjustment unit 50 is mounted on the inner wall of the mounting frame 41. The tension adjustment unit 50 includes a bottom rod 51 mounted on the inner wall of the mounting frame 41. The MBR membrane module 42 is slidably mounted on the bottom rod 51. A first pull rope 54 is fixed on one side of the MBR membrane module 42 to realize the tension adjustment of the MBR membrane module 42. The tension adjustment unit 50 also includes a side crossbar installed on the top of the mounting frame 41. A first take-up reel 55 is rotatably connected to one of the side crossbars via a first U-shaped frame. A guide wheel is installed at the bottom of the outer wall of the mounting frame 41. One end of the first pull rope 54 passes around the guide wheel and is connected to the first take-up reel 55. Preferably, a first guide tube is also installed on one side of the mounting frame 41, which is located above the guide wheel. That is, the first pull rope 54 passes around the guide wheel and then passes into the first guide tube, and then is connected to the first take-up reel 55. The guide wheel guides the first pull rope 54. A first drive member 56 with its output end connected to the first take-up reel 55 is installed on one side of the outer wall of the first U-shaped frame. A guide rod 52 is fixed inside the base rod 51. A movable tube 53 is slidably sleeved on the guide rod 52. The MBR membrane module 42 is fixed to the movable tube 53. Preferably, a semi-circular piece that fits against the movable tube 53 is fixed to one side of the MBR membrane module 42. A bolt is threaded through the semi-circular piece, and the MBR membrane module 42 is fixed to the movable tube 53 by the bolt. A first spring 57 is sleeved on the outer surface of the guide rod 52, and the two ends of the first spring 57 are respectively connected to one end of the movable tube 53 and one end of the guide rod 52. Specifically, in actual use, when it is necessary to... When adjusting the tension of the MBR membrane module 42, the first drive unit 56 is activated, causing the first winding wheel 55 to rotate clockwise and winding the first pull rope 54. During the winding process, the first pull rope 54 pulls the entire MBR membrane module 42 to move from front to back. At this time, the entire MBR membrane module 42 gradually tilts, thereby adjusting the tension of the MBR membrane module 42. Combined with intermittent pulse aeration, turbulence is used to remove sludge. It is worth noting that during the process, the top position of the MBR membrane module 42 remains stationary, and only the bottom position moves, thus causing it to tilt. After removing the MBR membrane unit 40, the tension of the MBR membrane module 42 can be adjusted in the above manner before offline rinsing, without the need to disassemble the membrane.

[0020] like Figure 2 , Figure 4 , Figure 5 and Figure 7 As shown, a dispersion unit 60 is also assembled on the inner wall of the mounting frame 41. The dispersion unit 60 includes a guide frame 61 fixed on the mounting frame 41. The MBR membrane module 42 is dispersed by an interlaced member 63 slidably mounted on the guide frame 61. The staggered component 63 includes a front rod 631, and a rear rod 632 is symmetrically arranged on one side of the front rod 631. A lever 633 is fixed on both the front rod 631 and the rear rod 632. The front rod 631 and the rear rod 632 are slidably connected to the guide frame 61 by a slider. Preferably, the positions of the levers 633 on the front rod 631 and the rear rod 632 are staggered. One end of multiple front rods 631 is fixed to a first connecting rod 634, and the first connecting rod 634 is inserted into a rear rod 632. After the first connecting rod 634 is inserted into the rear rod 632, it can slide within the rear rod 632. One end of multiple rear rods 632 is equipped with a second connecting rod 635, and the second connecting rod 635 is inserted into a front rod 631. After the second connecting rod 635 is inserted into the front rod 631, it can slide within the front rod 631. In particular, the other ends of multiple front rods 631 and multiple rear rods 632 are connected together by long rods. With the connecting rod, multiple front rods 631 and multiple rear rods 632 can move simultaneously. Specifically, during the process of the first pull rope 54 controlling the tilt of the MBR membrane module 42, since the front rod 631 and the rear rod 632 are far away from the sides of the MBR membrane module 42 in the initial state, the position of the rods will not obstruct the membrane module during the tilting process.

[0021] like Figure 4 , Figure 5 , Figure 7 , Figure 11 and Figure 12 As shown, the dispersing unit 60 also includes abutting rods 62 slidably connected in the guide frame 61. In particular, the inner sides of the two abutting rods 62 are in smooth contact with the front rod 631 and the rear rod 632. The front rod 631 and the rear rod 632 will not be unable to move left or right due to the abutting of the abutting rods 62. The inner wall of the guide frame 61 is provided with a sliding groove adapted to the slider. The two side walls of the sliding groove are respectively provided with a front outlet groove and a rear outlet groove adapted to the slider. When the front side rod 631 moves backward until its slider aligns with the front outlet groove, the front side rod 631 can move from left to right. When the rear side rod 632 moves forward until its slider aligns with the rear outlet groove, the rear side rod 632 can move from right to left. During the forward and backward movement of the front side rod 631 and the rear side rod 632, the levers 633 on their surfaces will insert into the MBR membrane module 42. When the front side rod 631 and the rear side rod 632 move relative to each other from left to right, they will pull the membrane body and disperse it, so that the MBR membrane module 42 can fully contact the sewage in the MBR tank 30. At the same time, it can also improve the cleaning effect during subsequent cleaning and prevent the hollow fiber membranes in the middle of each group from not being thoroughly cleaned. In particular, when the MBR membrane module 42 is in the tank, the above-mentioned method of dispersing the membrane can also improve the removal effect of underwater sludge, alleviate sludge accumulation, and improve the efficiency of offline cleaning after removal. At the same time, it can reciprocate, causing the membrane to vibrate. It should be noted that the amplitude of the reciprocating motion should not be too large, which helps to promote sludge detachment. A telescopic rod 64 is installed on one side of the push rod 62, and the other end of the telescopic rod 64 is fixed to the mounting frame 41. A second spring 65 is sleeved on the outer surface of the telescopic rod 64. In particular, in the initial state, the second spring 65 is in a compressed state. A connecting block is fixed inside the push rod 62. One end of the two connecting blocks is slidably connected to the front rod 631 and the rear rod 632 respectively. A second pull rope 67 is fixed on the outer wall of the connecting block. A second U-shaped frame is assembled on the other side crossbar. The second U-shaped frame and the first U-shaped frame are both rotatably connected to a second take-up wheel 66. The outer walls of the second U-shaped frame and the first U-shaped frame are both equipped with a second drive unit 68. Preferably, the first drive unit 56 and the second drive unit 68 are both motors. The inner side of the mounting frame 41 is fixed with a second guide rope tube. One end of the second pull rope 67 passes through the second guide rope tube and is connected to the second take-up wheel 66. In particular, in the initial state, a portion of the length of the second pull rope 67 is wound onto the second take-up wheel 66. In this state, the push rod 62 is in the state of compressing the second spring 65, and at the same time, the front rod 631 and the rear rod 632 are also away from the front and back of the MBR membrane module 42. Specifically, when it is necessary to control the front rod 631 and the rear rod 632 to move closer to each other until the lever 633 is inserted into the membrane gap, the second drive unit 68 is activated to control the second take-up wheel 66 to rotate counterclockwise, unwinding the second pull rope 67. At this time, the second spring 65, which is in a compressed state on the side close to the front rod 631, also gradually extends, and under the action of its elastic force, it drives the abutment rod 62 in contact with the front rod 631 to move from front to back, thereby pushing the front rod 631 to move from front to back. At the same time, the second spring 65 on the other side drives the abutment rod 62 in contact with the rear rod 632 to move from back to front, thereby pushing the rear rod 632 to move from back to front. When the sliders on the front rod 631 and the rear rod 632 correspond to the front outlet groove and the rear outlet groove, the second drive unit 68 is closed. At this time, the levers 633 on the front rod 631 and the rear rod 632 are inserted into the membrane gap.

[0022] like Figure 2 , Figure 4 , Figure 7 and Figure 8 As shown, the top of the mounting bracket 41 is also equipped with a middle crossbar, on which two toothed rods 69 are slidably connected. A gear 610 that meshes with the toothed rods 69 is rotatably connected to the middle of the middle crossbar. An electric push rod 611 with one end connected to one of the toothed rods 69 is fixed on the middle crossbar. In particular, the height of the middle crossbar and the side crossbar is higher than the height of the MBR tank 30. A slide block 612 is slidably connected to one side of the first link 634 and the second link 635. A third pull rope 613 is fixed to one side of the slide block 612. A positioning rod with one end fixed to the mounting bracket 41 is inserted into the top of the slide block 612. The positioning rod is designed so that the slide block 612 will not move back and forth when the first link 634 and the second link 635 move back and forth, so that the slide block 612 can remain in the original position. A third guide rope tube is fixed to one end of the positioning rod and the top of the outer wall of the mounting bracket 41. One end of the third pull rope 613, which passes through the two third guide rope tubes, is connected to the toothed rod 69. Specifically, after the operation of driving the front rod 631 and the rear rod 632 closer to each other is completed, the electric push rod 611 is activated to pull the connected toothed rod 69 inward. During the process, the gear 610 meshing with it drives the other toothed rod 69 to make relative movement, so that the front rod 631 moves from left to right and the rear rod 632 moves from right to left. During the process, the dispersion of the membrane is completed by the lever 633.

[0023] Specifically, this automated membrane filtration water treatment equipment operates / is used as follows: 1. Installation and Initial Setup 1.1 Equipment Assembly: Hoist the MBR membrane unit 40 into the MBR tank 30, ensuring that the connection between the water collection pipe and the product water pipe is sealed; 1.2 Tension initialization: Start the first drive unit 56, and the first pull rope 54 is wound up by the first take-up wheel 55, which pulls the bottom of the membrane module to move backward, so that the membrane filaments are in the initial tension state, and the top is fixed to the top of the mounting frame 41 to form an inclined angle; 1.3 Pre-adjustment of the dispersion unit 60: Start the second drive unit 68, rotate the second winding wheel 66 counterclockwise, unwind the second pull rope 67, so that the push rod 62 pushes the front rod 631 and the rear rod 632 to the position of the chute outlet groove under the elastic force of the second spring 65. At this time, the lever 633 is inserted into the gap of the membrane fibers to complete the initial positioning (steps 1.2 and 1.3 can be omitted, maintain the initial tension state of the MBR membrane module 42, and keep the lever 633 away from the membrane fibers). 2.
