Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a water distribution enhancement device for a PDS / PMS oxidation sewage treatment system. Background Art

[0002] With the acceleration of industrialization and urbanization, water pollution is becoming increasingly serious, especially the treatment of difficult-to-degrade organic pollutants has become a major challenge in the field of environmental protection. In the existing technology, photocatalytic technology has attracted widespread attention due to its green and efficient characteristics. However, when used alone, it has problems such as low treatment efficiency and easy deactivation of catalysts. Peroxymonosulfate (PMS) and peroxydisulfate (PDS) are strong oxidants that can generate a variety of active free radicals under photocatalytic conditions, significantly enhancing the oxidative degradation ability. However, how to effectively integrate the PMS and PDS photocatalytic processes and optimize the treatment efficiency remains a technical problem that needs to be solved urgently.

[0003] The working principle of photoactivated persulfate advanced oxidation technology is mainly based on the activation of persulfate (PMS or PDS) molecules under the action of light, which triggers a chain reaction to produce persulfate radicals (SO4 - ·), hydroxyl radical (·OH), superoxide radical (·O2 - ) and singlet oxygen (102). These highly active species have extremely strong oxidizing abilities and can effectively degrade organic pollutants and toxic substances in wastewater. However, when using persulfate to treat wastewater, the contact efficiency between highly active substances with strong oxidizing abilities and organic molecules is low, which in turn reduces the degradation reaction rate. Some wastewater contains a large amount of impurities, and when ultraviolet light is applied to the wastewater, the ultraviolet light cannot penetrate deep into the wastewater, resulting in low degradation efficiency for organic pollutants and toxic substances in the wastewater. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a water distribution strengthening device for a PDS / PMS oxidation sewage treatment system which can improve the degradation efficiency of organic pollutants and toxic substances in sewage and ensure the sewage treatment effect.

[0005] In order to achieve the above purpose, the technical solution provided by the utility model is:

[0006] A water distribution enhancement device for a PDS / PMS oxidation sewage treatment system includes a box body with multiple partitions fixed inside the box body, which divide the interior of the box body into multiple illumination chambers. A branch pipe is fixed in the upper end of each illumination chamber, and a nozzle is fixedly connected to the lower end of the branch pipe. Ultraviolet lamp panels are fixed on the side walls on both sides of the illumination chamber, and a diverter is provided in the illumination chamber. A transparent box is provided in the illumination chamber above the diverter, and a narrow and long channel is formed between the transparent box and the ultraviolet lamp board. Ultraviolet light strips are fixed on both sides of the left and right sides of the transparent box.

[0007] Specifically, the branch pipe is communicated with the manifold.

[0008] Specifically, the diverter includes two guide plates, which are symmetrically arranged on the left and right. The upper ends of the two guide plates are fixedly connected, the upper ends of the guide plates are inclined, and the lower ends of the inclined portions of the guide plates are inclined toward the ultraviolet lamp board on one side thereof. The lower ends of the inclined portions of the guide plates are arc-shaped and bent toward the ultraviolet lamp board on one side thereof to form a curved portion.

[0009] Specifically, the front and rear ends of the guide plate are fixedly connected to the front and rear side walls of the box body.

[0010] Specifically, the upper end of the transparent box is a pointed end, and the front and rear ends of the transparent box are fixedly connected to the front and rear side walls of the box body respectively.

[0011] Specifically, the transparent box is made of transparent glass.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. This device features UV lamp panels installed on both sides of the illumination chamber. The UV light emitted by the UV lamp panels illuminates the wastewater mist flowing within the chamber, fully activating the persulfate. This atomized wastewater increases the contact efficiency between oxygen-containing species such as sulfate radicals, hydroxyl radicals, superoxide radicals, and singlet oxygen and organic pollutants and toxic substances in the wastewater, thereby improving the degradation efficiency of these organic pollutants and toxic substances.

[0014] 2. When the sewage mist flows through the narrow channel between the transparent box and the ultraviolet lamp panel, the sewage mist flows in a thin ribbon. Under the dual illumination of the ultraviolet lamp panel and the ultraviolet lamp strip, the persulfate in the sewage can be completely activated, ensuring the content of oxygen-containing species such as sulfate free radicals, hydroxyl free radicals, superoxide free radicals and singlet oxygen in the sewage.

[0015] 3. After the sewage mist contacts the diverter, the sewage mist is diverted, and under the action of the inclined part and the arc part of the guide plate, turbulence can be generated in the process of the sewage mist contacting the guide plate and flowing downward. The turbulence can stir the sewage mist, and can make the oxygen-containing species such as sulfate free radicals, hydroxyl free radicals, superoxide free radicals and singlet oxygen in the sewage fully react with the organic pollutants and toxic substances in the sewage, thereby improving the degradation efficiency of organic pollutants and toxic substances in the sewage, and can ensure the treatment effect of sewage.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Example 1: Reference Figure 1 and Figure 2 As shown, a water distribution enhancement device for a PDS / PMS oxidation wastewater treatment system includes a housing 4, with multiple baffles 5 fixed within. The baffles 5 divide the interior of the housing 4 into multiple illumination chambers 11. Each illumination chamber 11 has a branch pipe 2 fixed at its upper end, connected to a manifold 1. A nozzle 3 is fixed at its lower end. Ultraviolet lamp panels 6 are fixed to the left and right sidewalls of the illumination chamber 11. Transparent boxes 9 are located within each illumination chamber 11, forming a narrow passage between the transparent boxes 9 and the UV lamp panels 6. Ultraviolet light strips 10 are fixed to the left and right sides of the transparent boxes 9.

[0022] The transparent box 9 is made of transparent glass. The upper end of the transparent box 9 is a pointed tip, and the front and rear ends of the transparent box 9 are fixedly connected to the front and rear side walls of the box body 4 respectively.

[0023] The sewage added with persulfate is distributed to multiple branch pipes 2 through a manifold 1. The sewage in the branch pipes 2 is atomized and sprayed into an irradiation chamber 11 through a nozzle 3. Under the illumination of ultraviolet lamp panels 6 arranged on the left and right sides of the irradiation chamber 11, the sewage mist flowing in the irradiation chamber 11 can be irradiated by the ultraviolet light emitted by the ultraviolet lamp panels 6, which can activate the persulfate and generate oxygen-containing species such as sulfate free radicals, hydroxyl free radicals, superoxide free radicals and singlet oxygen.

[0024] After sewage is atomized, the contact efficiency between oxygen-containing species such as sulfate radicals, hydroxyl radicals, superoxide radicals and singlet oxygen and organic pollutants and toxic substances in sewage can be improved, thereby improving the degradation efficiency of organic pollutants and toxic substances in sewage.

[0025] As the sewage mist flows through the narrow channel between the transparent box 9 and the UV lamp panel 6, it flows in a thin ribbon. Under the dual illumination of the UV lamp panel 6 and the UV light strip 10, the persulfate in the sewage is completely activated, ensuring the content of oxygen-containing species such as sulfate radicals, hydroxyl radicals, superoxide radicals, and singlet oxygen in the sewage. This further improves the degradation efficiency of organic pollutants and toxic substances in the sewage.

[0026] Example 2: Based on Example 1, refer to Figure 1 and Figure 3 As shown, a flow diverter is provided within the illumination chamber 11, located below the transparent box 9. The flow diverter comprises two guide plates 12, the front and rear ends of which are fixedly connected to the front and rear side walls of the housing 4. The two guide plates 12 are symmetrically arranged, with their upper ends fixedly connected. The upper portions of the guide plates 12 form an inclined portion 7, the lower ends of which are inclined toward the UV lamp board 6 on one side. The lower ends of the inclined portions 7 of the guide plates 12 are curved toward the UV lamp board 6 on the other side, forming a curved portion 8.

[0027] After the sewage mist contacts the diverter, the sewage mist is diverted, and under the action of the inclined portion 7 and the arc portion of the guide plate 12, turbulence can be generated in the process of the sewage mist contacting the guide plate 12 and flowing downward. The turbulence can stir the sewage mist, and can enable oxygen-containing species such as sulfate free radicals, hydroxyl free radicals, superoxide free radicals and singlet oxygen in the sewage to fully react with organic pollutants and toxic substances in the sewage, thereby improving the degradation efficiency of organic pollutants and toxic substances in the sewage, and can ensure the treatment effect of the sewage.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
