[0021] See also Figure 1-3The cleaning mechanism 6 includes a cover body 601, the bottom of the cover body 601 is slidably connected to the top of the anaerobic tank 1, and a plurality of scrapers 602 for cleaning the inner wall of the anaerobic tank 1 and the surface of the partition structure 5 are fixedly installed on the bottom of the cover body 601. Specifically, a bidirectional rotating motor 603 is fixedly installed inside the cover body 601, and the output shafts on both sides of the bidirectional rotating motor 603 are fixedly connected with rotating gears 604. A plurality of grooves 605 are provided on the top of the anaerobic tank 1, and the rotating gears 604 are meshed and connected inside the grooves 605. When the bidirectional rotating motor 603 is driven so that its output shaft drives the rotating gears 604 to rotate, the rotating gears 604 can drive the cleaning mechanism 6 to move through the grooves 605 at the top of the inner cavity of the anaerobic tank 1 through the cover body 601, and then the scrapers 602 clean the inner wall of the anaerobic tank 1 and the surface of the partition structure 5 during the movement.

[0022] See also Figure 1-3 The end of the scraper 602 away from the partition structure 5 is fixedly connected to a support bar 606 for supporting the scraper 602, the top of the support bar 606 is fixedly connected to the bottom of the cover body 601, the support bar 606 is internally rotatably connected to a threaded rod 607 for transporting the material scraped by the scraper 602 downward, and the support bar 606 is internally rotatably connected to an arc-shaped baffle 608 for collecting the material scraped by the scraper 602;

[0023] Specifically, there are multiple groups of threaded rods 607, and two groups of threaded rods 607 are fixedly connected with transmission gears 609, and the transmission gears 609 are connected with the rotating gears 604, so that when the rotating gears 604 rotate, the transmission gears 609 are driven to rotate. The outer walls of the two groups of threaded rods 607 are provided with rotating belts 610 through the driving wheel sleeves, and the tops of the other four groups of threaded rods 607 are rotatably connected to the inside of the rotating belts 610 through the driven wheels, so that when the threaded rods 607 drive the rotating belts 610 to rotate through the driving wheels, the rotating belts 610 drive the remaining four groups of threaded rods 607 to rotate through the driven wheels; the top of the arc baffle 608 is movably connected with a pressing plate 611, and the arc baffle 608 is rotatably connected with a rotating shaft 612 inside, and both ends of the rotating shaft 612 are rotatably connected to the inside of the support bar 606, so that the arc baffle 608 is turned over inside the support bar 606 through the rotating shaft 612;

[0024] More specifically, the outer walls of multiple groups of threaded rods 607 are fixedly connected with extension rods for supporting the threaded rods 607, and one end of the extension rods away from the threaded rods 607 is fixedly connected to the inside of the support bar 606; a sliding groove for limiting the pressure plate 611 is opened inside the support bar 606, and a block 704 is slidably connected inside the sliding groove, and the end of the block 704 away from the sliding groove is fixedly connected to the pressure plate 611.

[0025] See also Figure 1 and 4The partition structure 5 includes four groups of partitions 501, which are rotatably installed inside the anaerobic tank 1. Two partitions 501 form a group. The bottoms of the four groups of partitions 501 are rotatably connected to the inside of the anaerobic tank 1 through bearings. When in use, the partitions 501 can divide the inside of the anaerobic tank 1 into several small spaces, so as to treat the wastewater more efficiently and quickly.

[0026] See also Figure 1 and 4 The driving structure 7 includes a support block 701, one end of the support block 701 close to the baffle structure 5 is fixedly connected to the outer wall of the anaerobic tank 1, and the top of the support block 701 is rotatably connected to a connecting belt 702 for driving the baffle 501 to flip;

[0027] Specifically, the top of the support block 701 is rotatably connected to a turntable 703 for driving the connecting belt 702 to rotate. The outer wall of the turntable 703 is movably plugged into the inside of the connecting belt 702 through a second driving wheel. The tops of the four groups of partitions 501 are all plugged into the inside of the connecting belt 702 through driven wheels, so that when the connecting belt 702 rotates, the partitions 501 are driven to flip.

[0028] More specifically, a clamping block 704 is fixedly connected to the bottom of the turntable 703, and two groups of plug-in blocks 705 are fixedly connected to the top of the support block 701. When the turntable 703 drives the clamping block 704 to rotate and contact with a group of plug-in blocks 705, the clamping block 704 and the plug-in block 705 are engaged with each other, thereby limiting the turntable 703.

Therefore, when the turntable 703 drives the clamping block 704 to rotate and contact with a group of plug-in blocks 705, it is determined that the turntable 703 rotates 90°, thereby ensuring that the partition 501 always remains in a parallel state, avoiding the partition 501 from tilting at an angle, resulting in the cleaning mechanism 6 being unable to move on the partition 501.

[0029] The working principle of the utility model is:

[0030] First, the filter device 2 can perform preliminary filtering treatment on the wastewater. When the wastewater enters the anaerobic tank 1 through the first pipe and the first water pump, the baffle 501 is driven to rotate to adjust to the position of the rotating disk 703. Figure 1 state, so that the anaerobic tank 1 treats the wastewater. When the wastewater treatment is completed, the rotating disk 703 is rotated again to flip the partition 501 by 90 degrees, so that the water inside the anaerobic tank 1 enters the aerobic tank 3 through the second pipe and the second water pump, and the organic matter in the wastewater is decomposed by the aerobic tank 3. The wastewater after the decomposition treatment is completed can enter the membrane bioreactor 4 through the third pipe and the third water pump, so that the membrane bioreactor 4 purifies the wastewater, thereby facilitating the recycling of the wastewater for reuse;

[0031] After use, the rotating gear 604 can be driven to rotate by driving the bidirectional rotating motor 603, and the rotating gear 604 can drive the cleaning mechanism 6 to move inside the anaerobic tank 1 through the multiple sets of grooves 605 to clean the inner wall of the anaerobic tank 1 and the surface of the partition 501. During the cleaning process, the threaded rod 607 can push the muddy objects scraped by the scraper 602 downward, so that the muddy objects fall onto the surface of the pressing plate 611, and after accumulating to a certain weight, the pressing plate 611 is pressed downward, so that the arc baffle 608 is turned over to the surface through the rotating shaft 612. Figure 3 state, intercepting the muddy objects on the surface of the pressing plate 611, thereby preventing the muddy objects from escaping from the top of the pressing plate 611.
