DETAILED DESCRIPTION

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0015] The device for treating antibiotic wastewater with a MOFs membrane having a biomimetic pore structure comprises a treatment box 2, wherein an inlet pipe 1 is provided on the upper side of one end of the treatment box 2, and the lower side of the other end of the treatment box 2 is fixedly connected to a first water outlet channel 3, and the lower end of the first water outlet channel 3 is fixedly connected to a second water outlet channel 4; The upper side of the treatment box 2 is provided with an opening 201, and the middle position of the lower side of the interior of the treatment box 2 is a slope surface 202, and the slope surface 202 extends upward from one end close to the water inlet pipe 1 to the other end; A primary filter assembly is provided in the processing box 2 , and the primary filter assembly is driven by a driving assembly, which is connected to the processing box 2 .

[0016] In this embodiment, wastewater enters the treatment box 2 from the water inlet pipe 1, and the slope surface 202 on the lower side of the interior of the treatment box 2 is used to form a specific flow path for the wastewater in the treatment box 2. The first-level filter component moves under the drive component to perform preliminary filtration of impurities in the wastewater. The filtered wastewater is discharged through the first water outlet channel 3 and the second water outlet channel 4. The design of the slope surface 202 can make the wastewater flow slowly in the treatment box 2, prolong the contact time between the wastewater and the filter component, improve the filtration effect, and also facilitate the precipitation and collection of impurities. The setting of the first-level filter component and the drive component realizes the preliminary filtration of the wastewater. The drive component provides power for the movement of the filter component, so that it can more effectively intercept and remove larger particulate impurities in the wastewater.

[0017] The primary filter assembly includes a first connecting rod 12, a second connecting rod 13, a third connecting rod 14, a fourth connecting rod 16, a first gear rod 18, a second gear rod 17, a third gear rod 19 and a fourth gear rod 20. One end of the first connecting rod 12, the second connecting rod 13, the third connecting rod 14 and the fourth connecting rod 16 are respectively rotatably connected to one side of the processing box 2, one end of the first connecting rod 12 is fixedly connected to the first gear rod 18, one end of the second connecting rod 13 is fixedly connected to the second gear rod 17, one end of the third connecting rod 14 is fixedly connected to the third gear rod 19, one end of the fourth connecting rod 16 is fixedly connected to the fourth gear rod 20, and the third gear rod 19 and the fourth gear rod 20 are rotated along the processing box 2. Arranged in the height direction, the first baffle 18 and the second baffle 17 are arranged along the height direction of the processing box 2, the first baffle 18 and the fourth baffle 20 are arranged along the length direction of the processing box 2, the second baffle 17 and the third baffle 19 are arranged along the length direction of the processing box 2, the first connecting rod 12, the second connecting rod 13, the third connecting rod 14 and the fourth connecting rod 16 are arranged in a rectangular shape with the rotation connection points of the processing box 2, the first baffle 18 and the second baffle 17 are arranged corresponding to the lower end of the slope surface 202, the third baffle 19 and the fourth baffle 20 are arranged corresponding to the high end of the slope surface 202, and a discharge valve is provided on one side of the processing box 2 corresponding to the position of the first baffle 18 and the fourth baffle 20.

[0018] In this embodiment, each connecting rod of the first-stage filter assembly is rotatably connected to the treatment box 2 to form a movable structure. When the driving assembly drives the filter assembly to move, the blocking teeth on each lever cooperate with each other to intercept and filter impurities in the wastewater. Among them, the blocking teeth of the fourth lever 20 are more dense, which can filter smaller particles of impurities more finely. The arrangement and rotation connection points of each lever are arranged in a rectangular shape, so that the filter assembly can form a more comprehensive filtration area in the treatment box 2 during movement. The blocking teeth density of the fourth lever 20 is greater than that of other levers, which can achieve graded filtration of impurities of different particle sizes in the wastewater. The first lever 18 and the second lever 17 are set corresponding to the lower end of the slope surface 202, and the third lever 19 and the fourth lever 20 are set corresponding to the high end of the slope surface 202. This layout is matched with the design of the slope surface 202 to better adapt to the wastewater in The flow direction in the treatment box 2 improves the filtering effect. When the first baffle 18 and the second baffle 17 are opened, the third baffle 19 and the fourth baffle 20 are in a closed state to achieve filtration. After the water passes through, large impurities are blocked and fall on the slope surface 202. The impurities remain between the slope surface 202 and the first baffle 18 and the slope surface 202 and the fourth baffle 20. The opening 201 on the upper side of the treatment box 2 is convenient for removing large impurities. A discharge valve is provided. Opening the discharge valve facilitates the discharge of impurities accumulated in the treatment box 2.

[0019] The driving assembly includes a motor 22, a cavity 23, a limiting slot 6, a straight slot rod 7, a sliding rod 8, a first limiting slot rod 9, a second limiting slot rod 15, a rotating shaft 10, a rotating roller and a turntable 11. The two sides of the processing box 2 are respectively fixed with mounting brackets 301. The other ends of the first connecting rod 12 and the second connecting rod 13 are respectively arranged in the limiting slots of the first limiting slot rod 9, and the other ends of the first connecting rod 12 and the second connecting rod 13 are slidably connected to the first limiting slot rod 9. The other ends of the third connecting rod 14 and the fourth connecting rod 16 are respectively arranged in the limiting slots of the second limiting slot rod 15, and the other ends of the third connecting rod 14 and the fourth connecting rod 16 are slidably connected to the second limiting slot rod 15. The first limiting slot rod 9 and the second limiting slot rod 1 5, the lower end of the slide bar 8 is fixedly connected to the slide bar 8, the slide bar 8 is slidably connected to the limit slot 6, the limit slot 6 is fixedly connected to one of the mounting brackets 301, one end of the slide bar 8 is fixedly connected to the middle part of one side of the straight slot rod 7, the slide slot of the straight slot rod 7 is provided with the rotating shaft 10, the rotating shaft 10 is fixedly connected to the edge position of one side of the turntable 11, the center of the turntable 11 is fixedly connected to one end of the rotating roller, the two ends of the rotating roller are respectively rotatably connected to the cavity 23, the rotating roller is arranged in the cavity 23, the cavity 23 is fixedly connected to the mounting bracket 301, and the other mounting bracket 301 is fixedly connected to the motor 22 through the motor mounting plate 24, and the output shaft of the motor 22 is fixedly connected to the other end of the rotating roller.

[0020] In this embodiment, the motor 22 drives the rotating roller to rotate, which in turn drives the turntable 11 to rotate. The rotating shaft 10 on the turntable 11 slides in the sliding groove of the straight groove rod 7, thereby driving the straight groove rod 7 to move. The straight groove rod 7 drives the slide bar 8 to slide in the limit slot 6. The slide bar 8 in turn drives the first limit slot rod 9 and the second limit slot rod 15 to move, thereby causing the first connecting rod 12, the second connecting rod 13, the third connecting rod 14, and the fourth connecting rod 16 to drive the various blocking rods to move, thereby achieving reciprocating motion of the primary filter assembly. The cooperation between the limit slot 6 and the slide bar 8 limits the movement of the slide bar 8, ensuring that the slide bar 8 moves in a specific direction. The cooperation between the straight groove rod 7 and the rotating shaft 10 converts the circular motion of the turntable 11 into the linear motion of the straight groove rod 7.

[0021] The angle between the sloped surface 202 and the horizontal plane is 15-20 degrees. This angle allows the wastewater to flow within the treatment tank 2 at an appropriate speed, neither too fast, resulting in a short contact time between the wastewater and the filter assembly, nor too slow, affecting treatment efficiency. Furthermore, this angle facilitates the sedimentation and sliding of impurities on the sloped surface 202, facilitating their collection.

[0022] It also includes a reverse osmosis membrane, which is arranged in the secondary water outlet channel. The secondary water outlet channel and the treatment box 2 are arranged vertically. Relative and penetrating accommodating holes are respectively opened on both sides of the middle of the secondary water outlet channel. An osmotic membrane mounting plate 5 is inserted into the accommodating hole. An osmotic membrane mounting groove 21 for installing a reverse osmosis membrane is opened on the osmotic membrane mounting plate 5. A sealing ring is provided on the upper side of the osmotic membrane mounting plate 5 for sealing between the secondary water outlet channel. Both ends of the osmotic membrane mounting plate 5 are screwed with bolts in the outer area of the secondary water outlet channel. The bolts are used to prevent the osmotic membrane mounting plate 5 from escaping from the accommodating hole.

[0023] In this embodiment, a reverse osmosis membrane is arranged in the second water outlet channel 4. The wastewater enters the second water outlet channel 4 after the first-level filtration. The filtering effect of the reverse osmosis membrane further removes small molecular impurities, antibiotics and other pollutants in the wastewater. The reverse osmosis membrane is installed in the osmotic membrane mounting groove 21 of the osmotic membrane mounting plate 5. The osmotic membrane mounting plate 5 is inserted into the second water outlet channel 4 through the accommodating hole, sealed with a sealing ring, and fixed with bolts to prevent the osmotic membrane mounting plate 5 from detaching. The setting of the reverse osmosis membrane realizes the deep treatment of the wastewater. As the last filtration treatment of the entire treatment process, the purification degree of the wastewater is further improved, so that the treated wastewater can meet higher emission standards or reuse requirements. The setting of the osmotic membrane mounting plate 5 facilitates the installation and replacement of the reverse osmosis membrane. The setting of the sealing ring ensures the sealing of the reverse osmosis membrane installation, prevents wastewater leakage, and affects the treatment effect. The setting of the bolts fixes the osmotic membrane mounting plate 5 to ensure that it will not loosen or detach during operation.

[0024] The osmotic membrane mounting plate 5 is made of metal-organic framework material, which is a porous crystalline material formed by self-assembly of metal ions and organic ligands through coordination bonds. Due to its adjustable pore structure, large specific surface area, and diverse chemical functions, it has unique advantages in the fields of antibiotic separation, detection, and pollution control, and provides a suitable installation carrier for reverse osmosis membranes.

[0025] The reverse osmosis membrane utilizes a MOF membrane with a biomimetic pore structure. This membrane mimics the structure and function of biological pores, possessing unique pore structure and surface properties. Under pressure, as wastewater passes through the membrane, the biomimetic pore structure selectively filters water molecules and pollutant molecules, allowing water molecules to pass through the pores while intercepting pollutants such as antibiotics, thereby purifying the wastewater.

[0026] The method of use of the present invention is as follows: antibiotic wastewater is introduced into the treatment box 2 through the water inlet pipe 1, and the wastewater flows slowly under the action of the slope surface 202. At the same time, the first-level filter component is driven by the driving component to reciprocate, and the blocking teeth on each baffle perform preliminary filtering on impurities in the wastewater. Large particles of impurities are intercepted and precipitated between the slope surface 202 and the first baffle 18 and the slope surface 202 and the fourth baffle 20. The wastewater after the first-level filtration flows into the area provided with the reverse osmosis membrane through the first water outlet channel 3 and the second water outlet channel 4. Under the action of pressure and gravity, the wastewater passes through the bionic pore structure MOFs membrane, and water molecules pass through the membrane. Pollutants such as antibiotics are intercepted, thereby achieving deep purification of the wastewater. The purified water is discharged from the second water outlet channel 4. When impurities need to be cleaned after treatment, larger impurities can be manually removed through the opening 201 on the upper side of the treatment box 2; the impurities accumulated in the treatment box 2 can be discharged by opening the discharge valve; Regularly check the filtration effect of the reverse osmosis membrane. If the membrane performance is found to be degraded, unscrew the bolts, remove the membrane mounting plate 5, replace the reverse osmosis membrane, and reinstall it to ensure sealing to ensure continued efficient operation of the device. The above disclosure is only a specific embodiment of the present invention, but the present invention is not limited to this. Any changes that can be conceived by those skilled in the art should fall within the scope of protection of the present invention.
