Description

Technical Field

[0001] This utility model relates to the field of algal wastewater treatment technology, specifically to an advanced persulfate oxidation device. Background Technology

[0002] With the rapid development of society, environmental issues have received more attention, especially water pollution. The most common form of water pollution is eutrophication, which causes algae to grow in large quantities, leading to algal blooms, which deteriorate water quality and seriously affect water safety.

[0003] Existing methods for treating cyanobacterial wastewater mainly employ physical / chemical approaches. Physical methods involve manually or mechanically removing cyanobacteria from the water surface, increasing dissolved oxygen levels, improving water quality, directly replacing the water, reducing nutrient concentrations, and controlling cyanobacterial proliferation. However, these methods have limited effectiveness and are costly. Chemical methods involve adding chemical agents, such as copper-based agents and algaecides, to the water. These can quickly and effectively kill cyanobacteria, but may cause environmental pollution and are costly. Long-term use of chemical agents will also incur significant costs.

[0004] To address this, we provide a more efficient and environmentally friendly persulfate advanced oxidation device. Persulfate has strong oxidizing properties and can oxidize and decompose algal cells by generating strong oxidant sulfate free radicals, thereby achieving the purpose of algae removal. Utility Model Content

[0005] The purpose of this invention is to provide an advanced oxidation device for persulfate to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an advanced oxidation device for persulfate, comprising an oxidation treatment chamber, a matching top cover on the top of the oxidation treatment chamber, a feeding pipe connected to one side of the oxidation treatment chamber, wastewater inlets equidistantly distributed on the outer circumference of the upper part of the oxidation treatment chamber, three support legs fixedly connected to the bottom of the oxidation treatment chamber, a solenoid valve control slot on one side of the bottom of the oxidation treatment chamber, and a filter funnel inside the oxidation treatment chamber to remove impurities;

[0007] The oxidation treatment chamber has a built-in stirring mechanism, which mainly includes a drive motor located at the top of the chamber. The output end of the drive motor is fixedly connected to a stirring shaft. Filter plates are equidistantly fixed to the outer circumference of the stirring shaft. The surface of the filter plates is coated with a nano-catalyst coating. Under ultraviolet light irradiation, this nano-catalyst coating can generate highly oxidizing free radicals. These free radicals can destroy the cell structure of algae, thereby achieving sterilization and algae removal. The filter plates also contain electrode plates connected to an external power source. The electrode plates can be made of metal materials such as aluminum or iron. Taking an aluminum electrode plate as an example, the aluminum oxide and other active substances generated during electrolysis destroy the cell structure of cyanobacteria, thus removing them. During electrolysis, the aluminum anode is oxidized, releasing aluminum ions. These aluminum ions react with hydroxide ions in the water to form aluminum hydroxide precipitate, thereby adsorbing and removing cyanobacteria from the water. The active oxygen and hydroxyl free radicals generated during electrolysis also effectively kill cyanobacteria cells, improving wastewater treatment efficiency.

[0008] Preferably, the bottom surface of the top cover is provided with an ultraviolet irradiation device, which includes an ultraviolet lamp tube. The ultraviolet light generated by the ultraviolet lamp tube passes through the filter funnel and filter screen to efficiently inactivate algae, while preventing the deposition of algal residue on the filter funnel and filter screen, thus effectively improving the algae treatment efficiency.

[0009] Preferably, a basket funnel is fixedly installed on one side of the bottom of the oxidation treatment chamber. The inner wall of the basket funnel is provided with a semi-permeable membrane that allows only liquid to flow and does not allow solid solutes to pass through. The bottom of the basket funnel is provided with three sets of threaded holes, and a sterilization heating cylinder is threadedly connected through the threaded holes.

[0010] Preferably, the sterilization heating cylinder adopts a dual-cavity integrated structure, with the outermost cavity being the heating cavity. Both the outermost and innermost cavities are coated with a nano-catalyst coating to enhance heat transfer efficiency. After the wastewater undergoes preliminary solid-liquid separation through a basket funnel, the solid solutes flowing into the inner cavity of the sterilization heating cylinder, including various bacteria and algae cells, undergo further treatment. A three-way pipe is connected to the bottom of the sterilization heating cylinder, and the other end of the three-way pipe extends to the bottom of the oxidation treatment chamber through a one-way valve pump. Heating ring structures are equidistantly built into the heating cavity.

[0011] Preferably, the heating ring structure includes an annular metal tube coated with a nano-catalyst coating to effectively improve thermal energy utilization efficiency. An annular heat-conducting tube is installed inside the annular metal tube, and an annular insulating tube is installed inside the annular insulating tube. An annular heat-conducting plate is built into the annular insulating tube, and wire holes are equidistantly opened on the surface of the annular heat-conducting plate. Heating wires are built into the wire holes, which pass through the annular metal tube and extend out to connect to an external power source. When the electrode wire is energized, it can heat up rapidly. Through the heat conduction of the annular heat-conducting plate, the surface temperature of the annular metal tube is evenly distributed, thereby causing the temperature of the entire sterilization heating cylinder chamber to rise, thus sterilizing the solid solute at high temperature.

[0012] This invention provides an advanced oxidation apparatus for persulfate. It has the following beneficial effects:

[0013] (1) The present invention uses a nano-catalyst coating on the surface of the filter plate. Under ultraviolet light irradiation, the nano-catalyst coating can generate highly oxidizing free radicals. These free radicals can destroy the cell structure of algae, thereby achieving the effect of sterilization and algae removal.

[0014] (2) This utility model has an electrode plate inside the filter screen. The electrode plate is connected to an external power source. The electrode plate can be made of metal materials such as aluminum or iron. Taking the aluminum electrode plate as an example, the aluminum oxide and other active substances generated by the electrode plate during the electrolysis process are used to destroy the cell structure of cyanobacteria, thereby achieving the effect of removing cyanobacteria. When the electrode plate is in the electrolysis process, the aluminum anode will be oxidized and release aluminum ions. These aluminum ions react with hydroxide ions in the water to form aluminum hydroxide precipitate, thereby adsorbing and removing cyanobacteria in the water. The active oxygen and hydroxyl radicals generated during the electrolysis process can also effectively kill cyanobacteria cells and improve the wastewater treatment efficiency.

[0015] (3) This utility model adds sulfide and uses ultraviolet light to irradiate the sulfide to promote the generation of reactive oxygen free radicals. The strong oxidant sulfate free radicals are generated to oxidize and decompose algal cells, thereby removing algae contained in wastewater.

[0016] (4) By setting the heating ring structure, this utility model can achieve secondary heating of wastewater, ensuring that the cell structure of microorganisms such as cyanobacteria is completely destroyed, and further improving the purity of wastewater treatment. Attached Figure Description

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0026] Example 1:

[0027] A preferred embodiment of the advanced oxidation apparatus for persulfate provided by this utility model is, for example... Figure 1-6As shown: An advanced oxidation device for persulfate includes an oxidation treatment chamber 11. A matching top cover 12 is provided on the top of the oxidation treatment chamber 11. A feeding pipe 13 is connected to one side of the oxidation treatment chamber 11. Wastewater inlets 14 are equidistantly distributed on the outer circumference of the upper part of the oxidation treatment chamber 11. Three support legs 15 are fixedly connected to the bottom of the oxidation treatment chamber 11. A solenoid valve control slot 16 is provided on one side of the bottom of the oxidation treatment chamber 11. A filter funnel 26 is also provided inside the oxidation treatment chamber 11 to remove impurities. The oxidation treatment chamber 11 has a built-in stirring mechanism, which mainly includes a drive motor 21. The drive motor 21 is located on the top of the oxidation treatment chamber 11. A stirring shaft 22 is fixedly connected to the output end of the drive motor 21. Filter screen plates 24 are equidistantly fixed to the outer circumference of the stirring shaft 22. The surface of the filter screen plates 24... The filter screen 24 is coated with a nano-catalyst coating. Under ultraviolet light, the nano-catalyst coating can generate highly oxidizing free radicals. These free radicals can destroy the cell structure of algae, thereby achieving the effect of sterilization and algae removal. The filter screen 24 is equipped with an electrode plate 25, which is connected to an external power source. The electrode plate 25 can be made of metal materials such as aluminum or iron. Taking an aluminum electrode plate as an example, the aluminum oxide and other active substances generated by the electrode plate 25 during electrolysis can destroy the cell structure of cyanobacteria, thereby achieving the effect of removing cyanobacteria. During the electrolysis process, the aluminum anode of the electrode plate 25 is oxidized, releasing aluminum ions. These aluminum ions react with hydroxide ions in the water to form aluminum hydroxide precipitate, thereby adsorbing and removing cyanobacteria from the water. The active oxygen and hydroxide free radicals generated during the electrolysis process can also effectively kill cyanobacteria cells and improve wastewater treatment efficiency.

[0028] Example 2:

[0029] Please see Figures 1-6 Furthermore, based on Example 1, the following is obtained: an ultraviolet irradiation device is provided on the bottom surface of the top cover 12. The ultraviolet irradiation device includes an ultraviolet lamp tube 23. The ultraviolet light generated by the ultraviolet lamp tube 23 passes through the filter funnel 26 and the filter screen plate 24 to efficiently inactivate algae, while preventing the deposition of algal residues on the filter funnel 26 and the filter screen plate 24, thus effectively improving the algae treatment efficiency.

[0030] Further details reveal that a basket funnel 27 is fixedly installed on one side of the bottom of the oxidation treatment chamber 11. The inner wall of the basket funnel 27 is equipped with a semi-permeable membrane, which allows only liquid flow and not solid solutes. The bottom of the basket funnel 27 has three sets of threaded holes, through which a sterilization heating cylinder 28 is threadedly connected. The sterilization heating cylinder 28 adopts a dual-cavity integrated structure, with its outermost cavity being the heating cavity. Both the outermost and innermost cavities are coated with a nano-catalyst coating to enhance heat transfer efficiency. Wastewater passes through the basket... After the solid-liquid separation is initially achieved by funnel 27, the solid solutes, including various bacteria and algae cells, flow into the inner cavity of sterilization heating cylinder 28 for further treatment. A three-way pipe 29 is connected to the bottom of sterilization heating cylinder 28, and the other end of the three-way pipe 29 extends to the bottom of oxidation treatment tank 11 through a one-way valve pump. Heating ring structures 3 are equidistantly built into the heating chamber. By setting the heating ring structure 3, secondary heating of wastewater can be achieved, ensuring that the cell structure of microorganisms such as cyanobacteria is completely destroyed, and further improving the purity of wastewater treatment.

[0031] Example 3:

[0032] Please see Figures 1-6 Furthermore, based on Examples 1 and 2, the heating ring structure 3 includes an annular metal tube 31, the surface of which is coated with a nano-catalyst coating, which can effectively improve the thermal energy utilization efficiency. An annular heat-conducting tube 32 is arranged inside the annular heat-conducting tube 32, and an annular insulating tube 33 is arranged inside the annular insulating tube 33. An annular heat-conducting plate 34 is built into the annular insulating tube 33. The annular heat-conducting plate 34 has wire holes equidistantly opened on the circumference of its surface. The wire holes are filled with heating wires 35. The heating wires 35 pass through the annular metal tube 31 and extend out to connect with an external power source. After being energized, the electrode wires 35 can heat up rapidly. Through the heat conduction of the annular heat-conducting plate 34, the surface temperature of the annular metal tube 31 is evenly distributed, thereby causing the temperature of the entire sterilization heating cylinder 28 chamber to rise, thereby sterilizing the solid solute at high temperature.

[0033] The heating ring structure 3 consists of an annular metal tube 31, the surface of which is coated with a nano-catalyst coating, which not only improves thermal efficiency but also has good corrosion resistance and extends the service life of the equipment. The annular heat-conducting tube 32 is used to uniformly transfer heat, reduce energy consumption, and guide the temperature to the outside, so that the annular metal tube 31 can ultimately concentrate heat. The annular insulating tube 33 ensures the safety of the heating wire 35. In addition, the heating wire 35 on the annular heat-conducting plate 34 is made of high-purity nickel-chromium alloy material, which is resistant to high temperature and tensile strength, ensuring the stability and durability of heating.

[0034] In operation, when treating cyanobacteria wastewater, the wastewater is first introduced into the oxidation treatment tank through the wastewater inlet 14. Sulfide is added through the feed pipe 13. Ultraviolet light irradiation of the sulfide promotes the generation of reactive oxygen free radicals. These free radicals, which are strong oxidants, oxidize and decompose algal cells, thereby removing algae from the wastewater. Then, the drive motor 21 is started. The output shaft of the drive motor 21 drives the stirring shaft 22 to rotate. The stirring shaft 22 drives the filter plate 24 and electrode plate 25 to rotate. An external power supply provides power to the electrode plate 25, making the electrode plate 25 conductive. Subsequently, the electrode plate 25 can be made of metal materials such as aluminum or iron. Taking the aluminum electrode plate as an example, the aluminum oxide and other active substances generated by the electrode plate 25 during the electrolysis process can destroy the cell structure of cyanobacteria, thereby achieving the effect of removing cyanobacteria. When the electrode plate 25 is in the electrolysis process, the aluminum anode will be oxidized and release aluminum ions. These aluminum ions react with hydroxide ions in the water to form aluminum hydroxide precipitate, thereby adsorbing and removing cyanobacteria in the water. The strong oxidants such as active oxygen and hydroxyl radicals generated during the electrolysis process can also effectively kill cyanobacteria cells and improve wastewater treatment efficiency.

[0035] In addition, the ultraviolet light generated by the ultraviolet lamp tube 23 on the top cover 12 passes through the filter funnel 26 and the filter screen 24 to efficiently inactivate algae, while preventing the deposition of algal residues on the filter funnel 26 and the filter screen 24, thus effectively improving the algae treatment efficiency.

[0036] Afterwards, the solenoid valve controls the slot 16 to open, allowing wastewater to flow into the basket funnel 27. Since the inner wall of the basket funnel 27 is equipped with a semi-permeable membrane, the wastewater undergoes preliminary solid-liquid separation through the basket funnel 27 before flowing into the sterilization heating cylinder 28. The solid solutes, including various bacteria and algae cells, are then subjected to further treatment.

[0037] Heated by a heating ring, the heating wire 35 passes through the annular metal tube 31 and extends out to connect with an external power source. After being energized, the electrode wire 35 can heat up rapidly. Through the heat conduction of the annular heat-conducting plate 34, the surface temperature of the annular metal tube 31 is evenly distributed, thereby raising the temperature of the entire sterilization heating cylinder 28 chamber, thus sterilizing the solid solute at high temperature, and finally flowing out from the three-way pipe 29.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
