[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] like Figure 1 - Figure 7 As shown, an integrated MBR wastewater treatment device includes a water storage tank 1. A partition 8 is fixedly connected to the left side of the inner cavity of the water storage tank 1. A partition 9 is fixedly connected to the middle of the inner cavity of the water storage tank 1. A partition 3 10 is fixedly connected to the middle of the right side of the partition 2 9. A partition 4 11 is fixedly connected to the right side of the inner cavity of the water storage tank 1. An inlet 2 is fixedly connected to the upper left side of the water storage tank 1. An outlet 7 is fixedly connected to the lower right side of the water storage tank 1. A sedimentation mechanism 3 is fixedly connected to the left side of the partition 8. The sedimentation mechanism 3 includes a coarse screen 31, the right side of which is fixedly connected to the upper part of the left side of the partition 8, and a fine screen 32 is fixedly connected to the lower surface of the coarse screen 31. A drain outlet 34 is provided in the middle of the partition 8.

[0019] It should be noted that the storage tank 1, as the main container of the entire wastewater treatment device, provides installation space and a wastewater containment environment for each treatment unit, ensuring that the wastewater can pass through each treatment stage sequentially according to the preset process. Baffle 1 8 divides the sedimentation area, introducing wastewater into the sedimentation unit 3 for preliminary treatment. Baffle 2 9 separates the settled wastewater from the water quality adjustment area, allowing the settled wastewater to enter the water quality adjustment unit 4 for water quality adjustment. Baffle 3 10 further divides the biological reaction unit 5 into an anoxic tank 51 and an aerobic tank 52, creating a suitable environment for the growth and metabolism of different microorganisms. Baffle 4 11 separates the biological reaction wastewater from the membrane separation area, guiding the wastewater into the membrane separation unit 6 for final filtration. The inlet 2 is used to introduce the wastewater to be treated into the storage tank 1, serving as the entry point for the wastewater into the treatment system. The outlet 7 discharges the qualified water filtered by the membrane separation unit 6 from the storage tank 1, completing the entire wastewater treatment process. The coarse screen 31 intercepts larger suspended and floating solids in the wastewater, while the fine screen 32 further filters smaller impurities, reducing the burden on subsequent treatment units and preventing clogging. The drain outlet 34 allows the settled wastewater to be smoothly discharged from the sedimentation area and enter the water quality conditioning mechanism 4.

[0020] like Figure 3 As shown, a water quality regulating mechanism 4 is fixedly connected to the left side of partition 2 9. The water quality regulating mechanism 4 includes a support plate 1 41. A support plate 2 42 is fixedly connected to the middle of the left side of partition 2 9. Two feeding bins 44 distributed in front and behind are fixedly connected to the left and right sides of support plate 1 41 and support plate 2 42. A stirring assembly 43 is movably connected to the middle of support plate 1 41.

[0021] It should be noted that support plate 41 and support plate 42 provide installation support for the feeding hopper 44 and the mixing assembly 43, ensuring the stable operation of each component. The feeding hopper 44 is used to store and transport the chemical agents or nutrients required for water quality conditioning, ensuring that the wastewater quality meets the requirements for biological treatment.

[0022] like Figure 4 As shown, the stirring assembly 43 includes three rotating shafts 432. The upper part of the outer periphery of the rotating shafts 432 is rotatably connected to the middle part of the support plate 41. A transmission wheel 433 is fixedly connected to the side of the outer periphery of the rotating shafts 432 near the support plate 41. A drive gear 435 is fixedly connected to the lower surface of the drive wheel 433. A toothed belt 434 meshes with the outer periphery of the three drive wheels 433. Two driven gears 436 distributed on the left and right are meshed with the outer periphery of the drive gear 435. A stirring rod 437 is fixedly connected to the middle part of the driven gear 436. Multiple stirring blades 439 are fixedly connected to the outer periphery of the rotating shafts 432. Multiple stirring blades 438 are fixedly connected to the outer periphery of the stirring rod 437. A motor 431 is fixedly connected to the middle part of the upper surface of the support plate 41. The rotating shaft 432 located in the middle is fixedly connected to the output end of the motor 431.

[0023] It should be noted that motor 431 provides power to rotating shaft 432, driving the entire mixing system. Rotating shaft 432 drives transmission wheel 433 and stirring blade 439 to rotate, achieving mixing of the wastewater. Transmission wheel 433 and toothed belt 434 transmit the power of motor 431 to the three rotating shafts 432, achieving synchronous rotation. Driven gear 435 and driven gear 436 mesh to convert the rotation of rotating shaft 432 into the rotation of stirring rod 437, causing stirring blade 438 and stirring blade 439 to work together to thoroughly mix the wastewater and reagents, promoting chemical reactions and mass transfer.

[0024] like Figure 3 As shown, a biological reaction mechanism 5 is fixedly connected to the right side of the partition 2 9. The biological reaction mechanism 5 includes an anoxic tank 51 and an aerobic tank 52. The anoxic tank 51 is fixedly connected to the rear side of the partition 3 10, and the aerobic tank 52 is fixedly connected to the front side of the partition 3 10. An air pump 521 is fixedly connected to the upper part of the aerobic tank 52, and an aeration plate 522 is fixedly connected to the output end of the air pump 521.

[0025] It should be noted that in the anoxic tank 51, under anoxic conditions, denitrifying bacteria reduce nitrate nitrogen in the wastewater to nitrogen gas, thus achieving denitrification. Air pump 521 provides oxygen to the aerobic tank 52, and aeration plates 522 evenly disperse oxygen into the wastewater, providing sufficient dissolved oxygen for the growth and metabolism of aerobic microorganisms, promoting the decomposition of organic matter and the nitrification of ammonia nitrogen.

[0026] like Figure 5 As shown, a membrane separation mechanism 6 is fixedly connected to the right side of the partition 4 11. The membrane separation mechanism 6 includes a drain pipe 61, which is fixedly connected to the upper part of the right side of the inner cavity of the water storage tank 1. Two filter frames 62 are slidably connected to the upper part of the right side of the water storage tank 1. A microfiltration membrane 63 is fixedly connected to the bottom of the inner side of the filter frame 62. A handle 64 is fixedly connected to the front side of the filter frame 62. A sealing ring 66 is movably connected to the outer periphery of the front side of the filter frame 62. Locking components 65 are movably connected to the opposite sides of the two handles 64.

[0027] It should be noted that the drain pipe 61 introduces the wastewater after the biological reaction into the membrane separation area, providing a water flow channel for membrane filtration. The filter frame 62 and the microfiltration membrane 63 filter the wastewater, intercepting particulate matter. The two microfiltration membranes 63, located at the top and bottom, have different filtration gaps; the upper microfiltration membrane 63 has a larger filtration gap than the lower one. The handle 64 facilitates the installation and removal of the filter frame 62 by the operator. The sealing ring 66 ensures a tight seal between the filter frame 62 and the water storage tank 1, preventing wastewater leakage.

[0028] like Figure 6As shown, the locking component 65 includes a locking block 652, which is slidably connected to the upper part of the right side of the water tank 1. A lever 651 is fixedly connected to the front side of the locking block 652, and two compression springs 654 distributed on the left and right sides are fixedly connected to the opposite sides of the two locking blocks 652.

[0029] It should be noted that the locking block 652, by engaging with the filter frame 62, secures the filter frame 62 within the water storage tank 1, ensuring the stability of the filtration process. The lever 651 allows operators to manually operate the locking block 652 to lock and unlock the filter frame 62. The compression spring 654 provides elastic force to the locking block 652, enabling it to automatically reset and remain locked.

[0030] like Figure 6 As shown, two sliding rods 653 are slidably connected to opposite sides of the two locking blocks 652, and limit plates 655 are fixedly connected to opposite sides of the two sets of sliding rods 653.

[0031] It should be noted that the slide bar 653 and the limiting plate 655 are used to guide the sliding direction of the locking block 652, limit its range of motion, and ensure the normal operation of the locking component 65.

[0032] The working principle of this utility model is as follows: Wastewater enters the storage tank 1 through the inlet 2 and first flows into the sedimentation mechanism 3 area. The coarse screen 31 intercepts larger suspended solids and floating objects, and the fine screen 32 further filters smaller impurities. After sedimentation, the wastewater enters the water quality adjustment area through the outlet 34, where chemical agents or nutrients are added to the feeding hopper 44. The motor 431 starts, driving the central rotating shaft 432 to rotate. The transmission wheel 433 on the shaft drives the other two transmission wheels 433 to rotate synchronously through the toothed belt 434, causing the three rotating shafts 432 to rotate. The second stirring plate 439 stirs the wastewater. At the same time, the driving gear 435 on the rotating shaft 432 drives the driven gear 436 to rotate, and the driven gear 436 drives the stirring rod 437 to rotate. The first stirring plate 438 further stirs the wastewater, promoting the mixing of wastewater and chemicals and adjusting the water quality. After water quality conditioning, the wastewater enters the biological reaction unit 5 area. In the anoxic tank 51, denitrifying bacteria reduce nitrate nitrogen to nitrogen gas for denitrification. It then enters the aerobic tank 52, where air pump 521 delivers air to the aeration vents 522, providing dissolved oxygen for the aerobic microorganisms to decompose organic matter and nitrify ammonia nitrogen. The wastewater after biological reaction enters the membrane separation unit 6 area, flowing in through the drain pipe 61. It undergoes preliminary filtration through the microfiltration membrane 63 in the upper filter frame 62, followed by fine filtration through the microfiltration membrane 63 in the lower filter frame 62, removing impurities. When the filter frame 62 needs replacement or maintenance, move the lever 651 to disengage the locking block 652 from the filter frame 62, and then pull out the filter frame 62 by holding the handle 64. During installation, insert the filter frame 62 into the water storage tank 1, release the lever 651, and the locking block 652 will automatically reset and lock. The filtered, qualified water is discharged from the water storage tank 1 through the discharge port 7, completing the entire wastewater treatment process.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
