Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, and in particular relates to a device for treating aquaculture wastewater using MOFs materials. Background Technology

[0002] Antibiotic and organic pollution in water bodies has become a global environmental challenge, with its widespread presence and potential risks posing a serious threat to ecosystems and human health. With the rapid development of medicine, agriculture, and industry, the use of antibiotics and organic pollutants has increased year by year. These substances enter the aquatic environment through various pathways, leading to increasingly serious water pollution problems. Antibiotics, as an important class of drugs, are widely used in human medicine, animal husbandry, and aquaculture; however, their residues and accumulation in the environment have triggered the spread of antimicrobial resistance, forming "superbugs" that seriously threaten public health and safety. Furthermore, pesticides, industrial chemicals, and other organic pollutants also enter water bodies through agricultural runoff, industrial wastewater, and domestic sewage, further exacerbating water pollution. Existing aquaculture wastewater treatment equipment requires shutdown and disassembly, replacement, and reassembly before it can be reused, which seriously affects the efficiency of aquaculture wastewater treatment. For example, Chinese patent application number CN202020039334.0 discloses a wastewater treatment device for pig farming. A filter screen is installed at the bottom of the recovery cylinder. The recovery cylinder is hung on the upper opening of a filter box via hooks. Limiting mechanisms for the hooks are located on both sides of the upper surface of the filter box. A connecting hole is opened on the recovery cylinder corresponding to the wastewater inlet pipe. The two ends of a connecting rope are tied to the two hooks on the left and right sides. The right end of the horizontal shaft is fixedly connected to the output shaft of the winding motor, and a coil is fixedly connected to the left end of the horizontal shaft. A lifting device is wound on the coil. A hook is fixed to one end of the hoisting rope extending from the reel, and the other end of the wastewater outlet pipe is connected to the upper side of the outer circumference of the treatment tank. Inside the treatment tank, PP cotton filter layer and activated carbon filter layer are installed sequentially from top to bottom. Ozone generator is placed on one side of the treatment tank, and ozone inlet pipe extends into the treatment tank. Clean water outlet pipe is connected to the bottom side of the outer circumference of the treatment tank. However, the disadvantage of this technical solution is that when installing the PP cotton filter layer and activated carbon filter layer, the machine needs to be stopped for disassembly, replacement and reassembly. It can only be reused after the above operations are completed, which seriously affects the efficiency of aquaculture wastewater treatment. Utility Model Content

[0003] The purpose of this invention is to provide a device for treating aquaculture wastewater using MOFs materials, in order to solve the problems in the prior art. The specific technical solution is as follows: A device for treating aquaculture wastewater using MOFs materials includes a housing, an inlet pipe rotatably connected to the upper end of the housing, an outlet at the lower end of the housing, a wastewater switching component inside the housing, and two wastewater treatment components below the wastewater switching component. Both wastewater treatment components are fixed inside the housing by locking screws, and MOFs material plates are placed inside each wastewater treatment component.

[0004] Furthermore, a filter box is inserted into the box body, the filter box is located above the wastewater switching component, and the filter box is equipped with a filter screen.

[0005] Furthermore, the box is equipped with a partition plate, which divides the box into two chambers, both of which are connected to the outside through water outlets.

[0006] Furthermore, the wastewater switching assembly includes a Y-shaped bracket, which is fixed inside the housing. The Y-shaped bracket has two through holes, which are located above the two chambers respectively.

[0007] Furthermore, the Y-shaped bracket is rotatably connected to the lower end of the pressure plate, a counterweight is provided inside the pressure plate, and rubber rings are provided on both sides of the pressure plate. The pressure plate seals the through hole, and the rubber rings are pressed against the edge of the through hole.

[0008] Furthermore, both ends of the pressure plate are rotatably connected to the box body, and a turntable is fixed at both ends of the pressure plate. A rotating rod is fixed at an eccentric position on the outer surface of the turntable, and a fixing column is fixed on the outer wall of the box body. A spring is provided between the rotating rod and the fixing column.

[0009] Furthermore, a rotating cylinder is rotatably connected to the rotating rod.

[0010] Furthermore, the wastewater treatment component includes two storage boxes, both of which are fixed to the housing by locking screws, and the two storage boxes are located below the two through holes respectively.

[0011] Furthermore, the storage box has a concealed handle on the side and a strip-shaped hole at the bottom, and MOFs material plates are placed inside the storage box.

[0012] Furthermore, detection tubes are provided on both sides of the box, and the two chambers inside the box are connected to the outside through two detection tubes, with ball valves installed inside the detection tubes.

[0013] The advantages of this utility model are: Aquaculture wastewater is introduced into the tank through the inlet pipe. It then passes through a wastewater switching component and enters the first wastewater treatment unit. The MOF (Metal-Oxide-Foil) material plates in this unit remove antibiotics and organic matter from the water. The treated wastewater is then discharged through the outlet. When the filtration efficiency of the MOF material plates in this wastewater treatment unit deteriorates after prolonged use, the wastewater is redirected to the second wastewater treatment unit via the wastewater switching component. The MOF material plates in the second wastewater treatment unit remove antibiotics and organic matter from the water. The first wastewater treatment unit can then be removed for cleaning or replacement of its MOF material plates without affecting the second unit's wastewater treatment function. This eliminates the need for downtime and increases the efficiency of wastewater treatment. Attached Figure Description

Detailed Implementation

[0015] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0017] Example 1: like Figures 1-5 As shown, a device for treating aquaculture wastewater using MOFs materials includes a housing 1, an inlet pipe 2 rotatably connected to the upper end of the housing 1, an outlet 9 at the lower end of the housing 1, a wastewater switching component inside the housing 1, and two wastewater treatment components below the wastewater switching component. Both wastewater treatment components are fixed inside the housing 1 by locking screws 18, and MOFs material plates 21 are placed inside both wastewater treatment components. The working principle of the above technical solution is as follows: Aquaculture wastewater is added into the tank 1 through the inlet pipe 2. The aquaculture wastewater enters the first wastewater treatment component through the wastewater switching component. The MOFs material plate 21 in the wastewater treatment component removes antibiotics and organic matter from the water. The treated aquaculture wastewater is discharged through the outlet 9. When the filtration effect of the MOFs material plate 21 in the wastewater treatment component deteriorates after long-term use, the aquaculture wastewater is switched to the second wastewater treatment component through the wastewater switching component. The MOFs material plate 21 in the second wastewater treatment component removes antibiotics and organic matter from the water. The first wastewater treatment component can be removed to clean or replace the MOFs material plate 21 without affecting the operation of the second wastewater treatment component in treating aquaculture wastewater. There is no need to stop the machine and wait, thus increasing the efficiency of aquaculture wastewater treatment. MOFs material plate 21 is an emerging porous material with high specific surface area, tunable pore structure and functionalized sites, showing great application potential in environmental pollution control.

[0018] Example 2: like Figures 1-5 As shown, a filter box 3 is inserted into the housing 1. The filter box 3 is located above the wastewater switching component, and a filter screen 4 is provided inside the filter box 3. The working principle of the above technical solution is as follows: the filter screen 4 in the filter box 3 can filter out large particulate impurities in the aquaculture wastewater. The large particulate impurities remain in the filter box 3. The filter box 3 and the filter screen 4 can be pulled out from the box 1 for easy cleaning and replacement.

[0019] Example 3: like Figures 1-5 As shown, the box 1 is provided with a partition plate 16, which divides the box 1 into two chambers. Both chambers are connected to the outside through the water outlet 9. The wastewater switching assembly includes a Y-shaped bracket 14, which is fixed inside the housing 1. The Y-shaped bracket 14 has two through holes 15, which are located above the two chambers respectively. The Y-shaped bracket 14 is rotatably connected to the lower end of the pressure plate 11. The pressure plate 11 is provided with a counterweight 12. Rubber rings 13 are provided on both sides of the pressure plate 11. The pressure plate 11 is sealed at the through hole 15, and the rubber rings 13 are pressed against the edge of the through hole 15. Both ends of the pressure plate 11 are rotatably connected to the box body 1. Both ends of the pressure plate 11 are fixed with turntables 10. A rotating rod 5 is fixed at an eccentric position on the outer surface of the turntable 10. A fixing column 8 is fixed on the outer wall of the box body 1. A spring 7 is provided between the rotating rod 5 and the fixing column 8. The working principle of the above technical solution: Aquaculture wastewater flows into its corresponding wastewater treatment component through the first through hole 15. When the MOFs material plate 21 in the wastewater treatment component is used for a long time and its filtration effect deteriorates, the rotating rod 5 is rotated to drive the turntable 10 to rotate, which in turn drives the pressure plate 11 to rotate, and the pressure plate 11 presses on the through hole 15. The second through hole 15 is separated from the pressure plate 11 and the second through hole 15 is opened. The aquaculture wastewater flows into its corresponding wastewater treatment component through the second through hole 15. At this time, the wastewater treatment component with poor filtration effect can be taken out and the MOFs material plate 21 inside can be cleaned to achieve non-stop switching and increase the efficiency of aquaculture wastewater treatment. Under the tension of spring 7 and the gravity of counterweight 12, pressure plate 11 is pressed tightly against through hole 15, and rubber ring 13 plays a certain sealing role, allowing most of the aquaculture wastewater to flow through the open through hole 15.

[0020] Example 4: like Figures 1-5 As shown, the rotating rod 5 is rotatably connected to the rotating cylinder 6; The working principle of the above technical solution is as follows: by rotating the rotating cylinder 6, the rotating rod 5 and the turntable 10 are driven to rotate, which is convenient and quick.

[0021] Example 5: like Figures 1-5 As shown, the wastewater treatment assembly includes storage boxes 17. Both storage boxes 17 are fixed inside the housing 1 by locking screws 18. The two storage boxes 17 are located below the two through holes 15 respectively. The storage box 17 has a hidden handle 19 on its side and a strip hole 20 at the bottom. MOFs material plate 21 is placed inside the storage box 17. The working principle of the above technical solution is as follows: the aquaculture wastewater falls into the storage box 17 through the through hole 15, the MOFs material plate 21 removes antibiotics and organic matter from the water, and the treated aquaculture wastewater is discharged through the strip hole 20 and then discharged through the outlet 9. Remove the locking screw 18 to pull the storage box 17 out of the housing 1 for easy cleaning or replacement of the MOFs material plate 21.

[0022] Example 6: like Figures 1-5 As shown, detection tubes 22 are provided on both sides of the box 1. The two chambers inside the box 1 are connected to the outside through the two detection tubes 22 respectively. A ball valve 23 is provided inside the detection tube 22. The working principle of the above technical solution is as follows: Open the ball valve 23 to release the treated aquaculture wastewater through the detection pipe 22 for testing.
