Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and more specifically, to a wastewater treatment device. Background Technology

[0002] With the rapid development of industry and urbanization, the need to remove recalcitrant organic pollutants, pathogenic microorganisms, and other harmful substances from wastewater is becoming increasingly urgent, making wastewater treatment equipment a key piece of equipment in the environmental protection field. Among these, wastewater treatment equipment utilizing the synergistic effect of ultraviolet light and photocatalysis, through ultraviolet light exciting the photocatalyst to generate strong oxidizing free radicals, achieves the degradation of pollutants and the inactivation of microorganisms. Compared with traditional biochemical treatment and chemical oxidation processes, it has outstanding advantages such as simple operation, wide applicability, and no need for the addition of large amounts of chemical reagents.

[0003] However, wastewater typically contains impurities such as suspended solids, colloidal particles, chromatic substances, and large organic molecules. These substances strongly absorb and scatter ultraviolet (UV) light, significantly reducing its penetrating power. As the optical path length increases, the UV intensity decreases rapidly. Since the catalytic activity of photocatalysts depends on sufficient UV irradiation, when UV light cannot effectively penetrate to the photocatalyst surface in the wastewater, or when the intensity of UV light reaching the photocatalyst surface is insufficient, the photocatalyst cannot be fully excited, leading to low photocatalytic reaction efficiency and incomplete pollutant degradation. This problem severely limits the treatment capacity, treatment effect, and large-scale application of wastewater treatment equipment, becoming a core obstacle hindering the further promotion of this technology.

[0018] In wastewater treatment devices that combine ultraviolet (UV) lamps with photocatalytic units, the wastewater typically contains impurities such as suspended solids, colloidal particles, chromatic substances, and large organic molecules. These impurities strongly absorb and scatter the UV light emitted by the UV lamps, significantly reducing the penetration power of UV light in the wastewater. Furthermore, the intensity of UV light decreases rapidly with increasing optical path length. Since the catalytic activity of the photocatalytic unit depends on sufficient UV irradiation, when UV light cannot effectively penetrate to the area where the photocatalytic unit is located within the wastewater treatment chamber, or when the intensity of UV light reaching the surface of the photocatalytic unit is insufficient, the photocatalytic unit cannot be fully excited. This results in low photocatalytic reaction efficiency and incomplete pollutant degradation, severely limiting the treatment capacity, treatment effect, and large-scale application of this type of wastewater treatment device.

[0019] Example 1: This application proposes a wastewater treatment device, such as... Figure 1 and Figure 2 As shown, it includes a housing assembly 10 and multiple processing components 20.

[0020] The housing assembly 10 includes a housing unit 11, an inlet pipe 121, and an outlet pipe 122. The housing unit 11 has a sewage treatment chamber. The inlet pipe 121 and the outlet pipe 122 are respectively connected to the housing unit 11 and respectively communicate with the sewage treatment chamber. The inlet pipe 121 is used to input sewage into the sewage treatment chamber; the outlet pipe 122 is used to discharge the treated sewage from the sewage treatment chamber.

[0021] Multiple processing components 20 are included, each comprising an ultraviolet lamp 21 and a photocatalyst unit 22. The photocatalyst unit 22 is connected to a portion of the outer surface of the ultraviolet lamp 21. The ultraviolet lamp 21 is connected to the housing unit 11 and located within the wastewater treatment chamber. The ultraviolet light emitted by the ultraviolet lamp 21 can directly irradiate the inner surface of the photocatalyst unit 22 to which it is connected. The axes of the multiple ultraviolet lamps 21 are arranged parallel to each other; thus, the ultraviolet light irradiated by the ultraviolet lamps 21 can simultaneously irradiate the outer surface of the photocatalyst connected to adjacent ultraviolet lamps 21.

[0022] The processing component 20 includes a processing state, which includes: ultraviolet light emitted by the ultraviolet lamp 21 irradiating the photocatalytic unit 22 connected to it and the photocatalytic unit 22 connected to adjacent ultraviolet lamps 21. In this way, both the inner and outer surfaces of the photocatalytic unit 22 can be irradiated by ultraviolet light simultaneously, which can increase the amount of ultraviolet light received by a single photocatalytic unit 22, making up for the problems of insufficient ultraviolet light penetration and incomplete photocatalytic reaction in traditional devices, thereby enhancing the intensity of the catalytic reaction and improving the efficiency of pollutant purification.

[0023] Furthermore, such as Figure 4 As shown, the photocatalytic unit 22 includes a braided strip and a photocatalytic material. The braided strip is wrapped around a portion of the surface of the ultraviolet lamp tube 21, and the photocatalytic material is attached to the braided strip. The other portion of the surface of the ultraviolet lamp tube 21, which is not wrapped by the braided strip, is a light-transmitting area. The way the braided strip is wrapped allows the photocatalytic material to be tightly attached to the ultraviolet lamp tube 21, further shortening the ultraviolet light propagation path and reducing light attenuation in wastewater. Moreover, the ultraviolet lamp tube 21 retains a light-transmitting area that is not wrapped by the braided strip, which can prevent the photocatalytic unit 22 from excessively blocking the light source, thereby ensuring that some ultraviolet light can successfully penetrate the wastewater to the photocatalytic unit 22 of the adjacent treatment component 20.

[0024] The processing states include: a portion of the ultraviolet light emitted by the ultraviolet lamp tube 21 irradiates the photocatalyst material attached to the woven strip it is wrapped with, and another portion of the ultraviolet light emitted by the ultraviolet lamp tube 21 passes through the light-transmitting area and irradiates the photocatalyst material of the adjacent processing component 20.

[0025] Furthermore, such as Figure 5 As shown, multiple processing components 20 are arranged in multiple rows within the wastewater treatment chamber; each row of processing components 20 is arranged along a first direction; the projection intervals of any two adjacent rows of processing components 20 in a second direction are set. This provides a propagation channel for ultraviolet light, avoids excessive obstruction by adjacent rows of processing components 20, and ensures that the ultraviolet light emitted from the light-transmitting area of ​​the ultraviolet lamp tube 21 in one row can smoothly penetrate to the photocatalyst material of the adjacent row, reducing blind spots in light irradiation. The first and second directions are horizontal, with the second direction perpendicular to the first direction. Furthermore, both the first and second directions are horizontal and perpendicular to each other, forming a regular spatial layout, reducing flow resistance within the wastewater treatment chamber, allowing for a more uniform residence time of wastewater within the chamber, and further improving the stability of the treatment effect.

[0026] Furthermore, the processing component 20 is divided into multiple first segments and multiple second segments along its own axis; the light-transmitting area of ​​the first segment is larger than that of the second segment; the multiple first segments and multiple second segments are arranged alternately along the axis of the processing component 20. The first segment has a large light-transmitting area, which can emit more ultraviolet light for use by adjacent processing components 20; the second segment has a small light-transmitting area, which allows for a larger area of ​​attached photocatalyst unit 22 and a larger catalytic reaction area.

[0027] In any two adjacent columns of processing components 20, the projection of the first segment of one column of processing components 20 along the radial direction of the ultraviolet lamp tube 21 coincides with the second segment of the other column of processing components 20. Multiple first segments and second segments alternate along the axial direction, so that a single processing component 20 has the segmented function of strong light transmission and strong self-reaction at the same time. This avoids a single processing component 20 focusing only on light transmission or only on self-reaction, and can ensure the uniformity and efficiency of photocatalytic reaction.

[0028] Furthermore, in the direction from the outlet pipe 122 to the inlet pipe 121, the surface area of ​​the photocatalytic material in each row of treatment components 20 gradually increases. The wastewater on the outlet pipe 122 side has already undergone multiple rounds of photocatalytic treatment, resulting in a lower concentration of pollutants. Conversely, the wastewater on the inlet pipe 121 side has just entered the wastewater treatment chamber, with a higher concentration of pollutants. The larger surface area of ​​the photocatalytic material allows for a stronger catalytic reaction, leading to better wastewater treatment. This further enhances the wastewater treatment device's ability to treat wastewater, avoiding both weaker catalytic reactions in highly polluted areas and resource waste in low-pollution areas.

[0029] Furthermore, the cross-section of the woven strip is designed to be flat; the flat cross-section increases the surface area of ​​the woven strip, thereby allowing more photocatalytic material to adhere and enhancing the intensity of the catalytic reaction. The woven strip is detachably wound around the ultraviolet lamp tube 21, which facilitates the periodic replacement of photocatalytic carriers that are aging or have absorbed a large amount of impurities, and also allows for the adaptation of woven strips of different specifications to wastewater of different qualities.

[0030] Furthermore, the photocatalyst material includes a highly active photocatalyst and a broad-spectrum responsive photocatalyst; the highly active photocatalyst is attached to the side of the woven strip closest to the ultraviolet lamp tube 21; the broad-spectrum responsive photocatalyst is attached to the side of the woven strip away from the ultraviolet lamp tube 21; the highly active photocatalyst is used to absorb the ultraviolet light directly emitted by the ultraviolet lamp tube 21; and the broad-spectrum responsive photocatalyst is used to absorb the scattered ultraviolet light in the reaction chamber.

[0031] The highly active photocatalyst is installed close to the lamp tube, which shortens the light propagation path and reduces the attenuation effect of impurities in the wastewater on direct light. This ensures that the highly active photocatalyst always receives sufficient effective light, guaranteeing stable nuclear catalytic efficiency. The broad-spectrum responsive photocatalyst is attached to the side of the braided strip furthest from the lamp tube. It can specifically absorb ultraviolet light scattered by impurities in the wastewater treatment chamber. The scattered ultraviolet light has weak energy and dispersed propagation direction. This design enables the recovery and utilization of scattered light resources, reducing light energy loss.

[0032] It is worth noting that anatase phase titanium dioxide is preferred for highly active photocatalysts due to its high light absorption efficiency, which can precisely match the ultraviolet light emitted by the ultraviolet lamp tube 21. Nitrogen-doped titanium dioxide is preferred for broad-spectrum responsive photocatalysts, as it can respond to scattered ultraviolet light and even some visible light, compensating for insufficient scattered light intensity.

[0033] Furthermore, such as Figure 3 As shown, the wastewater treatment device also includes a flow-dispersing component 30; the flow-dispersing component 30 includes a drive unit and a flow-dispersing element; the flow-dispersing element is drivenly connected to the drive unit and is used to agitate the wastewater in the wastewater treatment chamber, preventing the formation of stagnant zones in local areas, allowing the wastewater to remain in the chamber for a more uniform time, ensuring that all wastewater can fully contact the ultraviolet light and photocatalytic materials, and reducing the situation where pollutants are discharged without reacting. The flow-dispersing element can be a rotatable fan blade, or it can be a liquid transfer pump or an aeration pump.

[0034] Furthermore, the agitator is a microbubble aeration unit; the microbubble aeration unit is connected to an external air supply device to deliver microbubbles into the sewage treatment chamber. The microbubbles can agitate the sewage in the sewage treatment chamber, and since the microbubbles contain oxygen, sufficient oxygen is supplied to the sewage treatment chamber during the aeration process. Under the synergistic effect of ultraviolet light and photocatalysis, the oxygen can be converted into strong oxidizing substances such as hydroxyl radicals. These substances can assist in the decomposition of recalcitrant pollutants such as macromolecular organic matter, further enhancing the degradation of pollutants.

[0035] Furthermore, there are multiple flow-dispersing components, each corresponding to one of the multiple processing components 20. This allows for the directional delivery of microbubbles around each processing component 20, achieving precise one-to-one flow dispersion. Moreover, during the rising process of the bubbles, they can adsorb suspended solids, colloidal particles, and other impurities in the wastewater, preventing impurities from depositing on the surface of the photocatalyst unit 22.

[0036] In other embodiments, the housing unit 11 includes a bottom plate 112 and a plurality of side plates 111, which together form a sewage treatment chamber.

[0037] In some other embodiments, the housing assembly 10 includes a transmission unit 12 and a sewage conveying assembly 40; the transmission unit 12 includes an inlet pipe 121 and an outlet pipe 122; the inlet pipe 121 and the outlet pipe 122 are respectively connected to the side plate 111; the sewage conveying assembly 40 is connected to the inlet pipe 121 and is used to convey sewage into the sewage treatment space through the inlet pipe 121.

[0038] In other embodiments, the outlet pipe 122 is positioned higher than the inlet pipe 121. This way, after the sewage enters the sewage treatment space from the inlet pipe 121, it needs to flow from bottom to top before it can be discharged from the outlet pipe 122. This utilizes gravity to extend the natural residence time of the sewage, providing sufficient time for the catalytic reaction and thus ensuring the sewage treatment effect.

[0039] In other embodiments, a wastewater detection component can be installed inside the wastewater treatment chamber near the outlet pipe 122. This component directly detects the quality of the wastewater about to be discharged, enabling timely detection of substandard treatment and preventing the direct discharge of unqualified wastewater. When the wastewater quality is substandard, the inflow rate through the inlet pipe 121 can be reduced, thereby extending the residence time of the wastewater within the wastewater treatment chamber and ensuring the effectiveness of wastewater treatment.

[0040] Those skilled in the art will understand that the above embodiments are specific examples of implementing this disclosure, and in practical applications, various changes can be made in form and detail without departing from the scope of this disclosure.
