Description

Technical Field

[0001] This utility model relates to the field of magnetic Fenton wastewater technology, and in particular to a magnetic Fenton wastewater treatment device. Background Technology

[0002] Magnetic Fenton is an advanced oxidation technology used to treat recalcitrant organic wastewater. This technology combines traditional Fenton reagents with magnetic materials to improve reaction efficiency and facilitate catalyst separation.

[0003] In the prior art, such as Chinese Patent No. CN221821955U, a wastewater treatment device using iron-carbon micro-electrolysis coupled with electromagnetic Fenton reaction is described. This device includes a main body and an auxiliary body, with the auxiliary body located at the outer end of the main body. The main body includes a casing, an outlet, and a catalytic anode plate. The outlet is fixedly located on the right side of the casing. This iron-carbon micro-electrolysis coupled with electromagnetic Fenton reaction device magnetizes water molecules during the Fenton process, disrupting their surface hydration and making it easier for advanced oxidizing media (such as ·OH) to function. Furthermore, in addition to the advanced oxidizing media produced by the Fenton reaction itself, this invention also includes advanced oxidizing media generated by catalytic electro-oxidation through an inert catalytic electrode plate. Iron-carbon filler, acting as a granular electrode, forms a three-dimensional electrode system with the electrode plate. The anode surface of the granular electrode can directly oxidize H2O to ·OH, effectively improving the practicality of the device.

[0004] While the above-mentioned scheme has the advantages mentioned above, its disadvantage is that after the reaction is completed, the magnetic nanoparticles cannot be uniformly adsorbed from the wastewater, resulting in incomplete adsorption of the magnetic nanoparticles, which reduces the overall treatment efficiency of the magnetic Fenton wastewater treatment device. Furthermore, it is not convenient to collect the magnetic nanoparticles uniformly, which reduces the practicality of the magnetic Fenton wastewater treatment device. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art that after the reaction is completed, the magnetic nanoparticles cannot be uniformly adsorbed from the wastewater, resulting in the magnetic nanoparticles not being completely adsorbed, which reduces the overall treatment efficiency of the magnetic Fenton wastewater treatment device and makes it inconvenient to collect the magnetic nanoparticles uniformly, thus reducing the practicality of the magnetic Fenton wastewater treatment device.

[0011] In a preferred embodiment, threaded rods are movably connected to both sides of the inner wall of the expansion plate, and clamping plates are threadedly connected to the outer surface of the threaded rods.

[0012] The technical effect of adopting the above-mentioned further solution is that the hand crank drives the threaded rod two to reverse, the threaded rod two drives the clamping plate to move horizontally, and at this time the limiting post limits the clamping plate.

[0019] In a preferred embodiment, a collection box is provided on the top of the extension plate.

[0020] The technical advantage of adopting the above-mentioned further solution is that the collection box can be removed, and then the magnetic nanoparticles can be recycled.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] 1. In this invention, pre-treated wastewater (with pH adjusted and large particulate impurities removed) is first introduced into a non-magnetic treatment dish through an inlet pipe connected to the wastewater source. The dish is then filled with the wastewater. Magnetic nanoparticle catalyst is added to the wastewater, along with an appropriate amount of hydrogen peroxide and oxygen. Under suitable temperature and pH conditions, the reaction proceeds fully through aeration (providing oxygen to the water). Ferrous ions catalyze the decomposition of hydrogen peroxide to generate hydroxyl radicals, which oxidize and degrade organic pollutants in the wastewater, thus completing the wastewater treatment. After treatment, to facilitate the separation of the magnetic nanoparticles, the operator uses a controller to activate the electric... The machine consists of a motor that drives a threaded rod to rotate forward. As the threaded rod rotates, it causes a sliding block to descend vertically. Simultaneously, the controller activates an electromagnetic rod, filling it with magnetic force. As the sliding block continues to descend, the electromagnetic rod gradually enters the wastewater surface and uses magnetic force to attract a large number of magnetic nanoparticles. As the sliding block continues to descend, the electromagnetic rod gradually touches the bottom. Then, the controller reverses the motor, causing the electromagnetic rod to rise vertically, attracting the magnetic nanoparticles in the wastewater again and gradually moving away from the surface. At this point, the electromagnetic rod is fully saturated with magnetic nanoparticles, thus uniformly removing them from the wastewater and ensuring complete adsorption. This improves the overall treatment efficiency of the magnetic Fenton wastewater treatment device.

[0023] 2. In this invention, after adsorption is complete, the operator starts motor two using the controller. Motor two drives the turntable to rotate and rotates the electromagnetic rod to the top of the collection box. Then, motor two is turned off, and the electromagnetic rod is turned off. The electromagnetic rod then loses its magnetic force, and a large number of magnetic nanoparticles fall into the collection box. When the collection box needs to be removed, the operator manually rotates the hand crank in the opposite direction. The hand crank drives the threaded rod two to rotate in the opposite direction, and the threaded rod two drives the clamping plate to move horizontally. At this time, the limiting post limits the clamping plate to prevent it from spinning freely. The clamping plate no longer holds the collection box, and the operator removes the collection box and then recycles the magnetic nanoparticles. This facilitates the unified collection of magnetic nanoparticles and improves the practicality of the magnetic Fenton wastewater treatment device. Attached Figure Description

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1, please refer to Figure 1 - Figure 4This utility model provides a technical solution: a magnetic Fenton wastewater treatment device, including a base plate 1, a non-magnetic treatment dish 101 fixedly connected to the bottom edge of the base plate 1, a turntable 108 movably connected to the top edge of the base plate 1, a threaded rod 103 movably connected to the top of the turntable 108, a hollow plate 102 fixedly connected to the top of the turntable 108, a motor 104 fixedly installed at the center of the top of the hollow plate 102, the output end of the motor 104 fixedly connected to one end of the threaded rod 103, and the outer surface of the threaded rod 103... A sliding block 105 is threadedly connected to the surface of the non-magnetic treatment dish 101. A fixing rod 106 is fixedly connected to the bottom of the sliding block 105 near the edge. An electromagnetic rod 107 is fixedly installed at the bottom end of the fixing rod 106. A tray 109 is fixedly connected to one side of the outer surface of the non-magnetic treatment dish 101. A motor 110 is fixedly installed at the top center of the tray 109. The output end of the motor 110 is fixedly connected to one side of the turntable 108. A water outlet pipe 111 and a water inlet pipe 112 are fixedly embedded on the outer surface of the non-magnetic treatment dish 101.

[0032] In this embodiment, pre-treated wastewater with adjusted pH and removed large particulate impurities is first introduced into the non-magnetic treatment dish 101 through inlet pipe 112. Inlet pipe 112 is connected to the wastewater source, filling the non-magnetic treatment dish 101 with the wastewater to be treated. Then, magnetic nanoparticle catalyst is added to the wastewater, along with an appropriate amount of hydrogen peroxide and oxygen. Under suitable temperature and pH conditions, the reaction proceeds fully through aeration. Aeration provides oxygen to the water, and ferrous ions catalyze the decomposition of hydrogen peroxide to generate hydroxyl radicals, which oxidize and degrade organic pollutants in the wastewater, thus completing the wastewater treatment. After treatment, to facilitate the separation of the magnetic nanoparticles, the operator uses a controller to start motor 104. Motor 104 drives a screw thread... When rod 103 rotates forward, it drives sliding block 105 to descend vertically. Simultaneously, the controller activates electromagnetic rod 107, filling it with magnetic force. As sliding block 105 continues to descend, electromagnetic rod 107 gradually enters the wastewater surface and uses magnetic force to adsorb a large number of magnetic nanoparticles. As sliding block 105 continues to descend, electromagnetic rod 107 gradually touches the bottom. Then, the operator uses the controller to reverse motor 104, causing electromagnetic rod 107 to rise vertically, adsorbing the magnetic nanoparticles in the wastewater once more and gradually moving away from the surface. At this point, electromagnetic rod 107 is fully adsorbed with a large number of magnetic nanoparticles, thus achieving uniform adsorption of magnetic nanoparticles from the wastewater. This ensures thorough adsorption of magnetic nanoparticles and improves the overall treatment efficiency of the magnetic Fenton wastewater treatment device.

[0033] Example 2, as Figure 1 - Figure 4As shown, an extension plate 2 is fixedly connected to one side of the outer surface of the non-magnetic treatment dish 101. Limiting posts 202 are fixedly connected to both sides of the inner wall of the extension plate 2. Threaded rods 203 are movably connected to both sides of the inner wall of the extension plate 2. A clamping plate 204 is threadedly connected to the outer surface of the threaded rods 203. The inside of the clamping plate 204 is movably sleeved on the outer surface of the limiting posts 202. A hand crank 205 is movably connected to one side of the outer surface of the extension plate 2. One end of the hand crank 205 is fixedly connected to one end of the threaded rods 203. A collection box 201 is provided on the top of the extension plate 2.

[0034] In this embodiment, after adsorption is complete, the operator starts motor 110 using the controller. Motor 110 drives turntable 108 to rotate and rotates electromagnetic rod 107 above collection box 201. Then, motor 110 is turned off, and electromagnetic rod 107 is turned off. Electromagnetic rod 107 immediately loses its magnetic force, and a large number of magnetic nanoparticles fall into collection box 201. When collection box 201 needs to be removed, the operator manually rotates hand crank 205 in the opposite direction. Hand crank 205 drives threaded rod 203 to reverse, and threaded rod 203 drives clamping plate 204 to move horizontally. At this time, limiting post 202 limits clamping plate 204 to prevent clamping plate 204 from spinning freely. At this time, clamping plate 204 no longer clamps collection box 201, and the operator removes collection box 201 and then recycles the magnetic nanoparticles. This facilitates the unified collection of magnetic nanoparticles and improves the practicality of the magnetic Fenton wastewater treatment device.

[0035] Working Principle: In operation, pre-treated wastewater (with pH adjusted and large particulate impurities removed) is first introduced into the non-magnetic treatment dish 101 through inlet pipe 112. Inlet pipe 112 is connected to the wastewater source, filling the non-magnetic treatment dish 101 with the wastewater to be treated. Then, a magnetic nanoparticle catalyst is added to the wastewater, along with an appropriate amount of hydrogen peroxide and oxygen. Under suitable temperature and pH conditions, the reaction proceeds fully through aeration. Aeration provides oxygen to the water, and ferrous ions catalyze the decomposition of hydrogen peroxide to generate hydroxyl radicals, which oxidize and degrade impurities in the wastewater. The process involves treating the wastewater by removing pollutants. After treatment, to facilitate the separation of magnetic nanoparticles, the staff uses a controller to start motor 104. Motor 104 drives threaded rod 103 to rotate forward. As threaded rod 103 rotates, it causes sliding block 105 to descend vertically. Simultaneously, the controller activates electromagnetic rod 107, filling it with magnetism. As sliding block 105 continues to descend, electromagnetic rod 107 gradually enters the wastewater surface and uses magnetic force to attract a large number of magnetic nanoparticles. As sliding block 105 continues to descend, electromagnetic rod 107 gradually touches the bottom. Then, the staff uses the controller... Motor 104 is reversed, causing electromagnetic rod 107 to rise vertically and adsorb the magnetic nanoparticles in the wastewater once more, gradually moving away from the liquid surface. At this point, electromagnetic rod 107 is saturated with a large number of magnetic nanoparticles, thus uniformly adsorbing them from the wastewater and ensuring complete adsorption. This improves the overall treatment efficiency of the magnetic Fenton wastewater treatment device. After adsorption is complete, the operator uses the controller to start motor 110, which drives the turntable 108 to rotate and rotates electromagnetic rod 107 above collection box 201. Then, motor 110 is turned off, followed by the shutdown of electromagnetic rod 107. The electromagnetic rod 107 immediately loses its magnetic force, and a large number of magnetic nanoparticles fall into the collection box 201. When the collection box 201 needs to be removed, the operator manually rotates the hand crank 205 in the reverse direction. The hand crank 205 drives the threaded rod 203 to reverse, and the threaded rod 203 drives the clamping plate 204 to move horizontally. At this time, the limiting post 202 limits the clamping plate 204 to prevent the clamping plate 204 from spinning freely. At this time, the clamping plate 204 no longer clamps the collection box 201, and the operator removes the collection box 201 and then recycles the magnetic nanoparticles. This facilitates the unified collection of magnetic nanoparticles and improves the practicality of the magnetic Fenton wastewater treatment device.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
