Description

Technical Field

[0001] This utility model relates to the field of organic wastewater treatment technology, and more specifically, to an ozone catalytic oxidation treatment system for organic wastewater. Background Technology

[0002] Organic wastewater refers to wastewater containing organic pollutants, including carbohydrates, proteins, oils, phenols, alcohols, and organic acids. Its sources are widespread, including industrial production (such as chemical, pharmaceutical, printing and dyeing, and papermaking industries), agricultural activities (such as livestock wastewater and agricultural runoff), and domestic sewage. Organic wastewater has a complex composition, high chemical oxygen demand (COD) and biochemical oxygen demand (BOD), and some parts have poor biodegradability. If discharged directly without effective treatment, it will cause serious pollution to water bodies, soil, and other ecological environments, endangering the survival of aquatic organisms, polluting groundwater resources, and potentially threatening human health through the food chain.

[0003] Ozone catalytic oxidation of organic wastewater is an advanced oxidation technology that utilizes the highly oxidizing hydroxyl radicals generated by ozone under the action of a catalyst to non-selectively oxidize and degrade pollutants in organic wastewater. During the treatment process, ozone reacts on the catalyst surface to generate hydroxyl radicals with extremely high oxidation potentials. These radicals can rapidly react with organic pollutants, decomposing them into small molecules such as carbon dioxide and water, or even completely mineralizing them. This reduces the pollution level of the organic wastewater, improves its biodegradability, and makes subsequent treatment easier to meet standards.

[0004] Existing ozone catalytic oxidation treatment systems generally consist of an organic wastewater storage tank, an ozone generation and delivery unit, and a reaction tower. The reaction tower, filled with a catalyst, is the core of the entire ozone catalytic oxidation reaction and plays a crucial role in treating the organic wastewater. Organic wastewater flows from the storage tank into the reaction tower, where it comes into full contact with the ozone delivered to the tower. Under the action of the catalyst, an oxidation reaction occurs, thereby removing organic pollutants. However, under natural conditions, the solubility of ozone in wastewater is relatively low, which limits the amount of ozone participating in the reaction and prevents it from fully exerting its oxidizing effect, resulting in poor treatment efficiency for the organic wastewater.

[0005] Taking the Chinese utility model patent disclosed in application number CN201220602617.7, which describes an ozone catalytic oxidation treatment device for organic wastewater, as an example, it also suffers from the problem that the amount of ozone dissolved in the wastewater is low, which in turn affects the treatment effect of organic wastewater. Utility Model Content

[0006] The purpose of this invention is to provide an ozone catalytic oxidation treatment system for organic wastewater, which aims to solve the technical problems mentioned in the background.

[0007] The embodiments of this utility model are implemented as follows:

[0008] This application provides an ozone catalytic oxidation treatment system for organic wastewater, comprising: a vertical reaction tower, wherein a reaction chamber, a transition chamber, and a mixing chamber are arranged sequentially from top to bottom inside the tower; a catalyst reaction section is arranged in the reaction chamber; multiple baffles are arranged in the transition chamber, forming a vertical serpentine flow channel; the top and bottom of the vertical serpentine flow channel are respectively connected to the reaction chamber and the mixing chamber; wherein the reaction chamber is connected to a water storage tank; and a mixing assembly, including a base, a rotating shaft, and multiple arc-shaped tubes, wherein the base is disposed within the mixing chamber. The aforementioned rotating shaft is rotatably mounted on the aforementioned base, the aforementioned base is provided with a first flow channel, the aforementioned rotating shaft is provided with a second flow channel that connects to the aforementioned first flow channel, and the aforementioned first flow channel and the aforementioned second flow channel are both located on the central axis of the aforementioned rotating shaft. One end of any of the aforementioned arc-shaped tubes is connected to the aforementioned second flow channel, and the other end is connected to the aforementioned mixing chamber. When at least one of the aforementioned arc-shaped tubes sprays organic wastewater, it drives the aforementioned rotating shaft to rotate. An organic wastewater supply assembly is used to supply organic wastewater to the aforementioned first flow channel. An ozone generation and delivery unit is used to deliver ozone to the aforementioned mixing chamber.

[0009] Furthermore, based on the aforementioned scheme, a rotary joint connecting the first flow channel and the second flow channel is provided at their junction to accommodate the relative rotation of the shaft and the base.

[0010] Furthermore, based on the aforementioned scheme, it also includes an ultrasonic generator and an ultrasonic transducer disposed in the aforementioned mixing cavity.

[0011] Furthermore, based on the aforementioned scheme, the ozone generation and delivery unit includes an oxygen cylinder and an ozone generator that cooperate with each other. The ozone outlet of the ozone generator is connected to a nano-aeration disc, which is disposed at the bottom of the mixing chamber.

[0012] Furthermore, based on the aforementioned scheme, a photocatalyst layer is provided on the surface of any of the aforementioned baffles; wherein, the aforementioned vertical reaction tower is provided with a transparent part, the aforementioned transparent part is opposite to the aforementioned transition cavity, and an ultraviolet irradiation lamp is provided on the outer side of the aforementioned transparent part for irradiating the aforementioned photocatalyst layer.

[0013] Furthermore, based on the aforementioned scheme, the ultraviolet light irradiation lamp cover is equipped with a protective cover.

[0014] Furthermore, based on the aforementioned scheme, any of the baffles is equipped with a heating element.

[0015] Furthermore, based on the aforementioned scheme, the organic wastewater supply component includes a storage tank and a transfer pump. The storage tank is used to store organic wastewater, and the transfer pump is used to transport the organic wastewater stored in the storage tank to the first flow channel.

[0016] Furthermore, based on the aforementioned scheme, a water distributor is provided at the location where the vertical serpentine flow channel connects to the aforementioned reaction chamber.

[0017] Furthermore, based on the aforementioned scheme, the top of the reaction chamber is sequentially connected to a demister, an ozone exhaust gas destroyer, and an explosion-proof fan.

[0018] Compared with the prior art, the embodiments of this utility model have at least the following advantages or beneficial effects:

[0019] In the actual operation of the treatment system of this application, the organic wastewater supply component continuously delivers organic wastewater to the first flow channel. The wastewater flows sequentially through the first and second flow channels before entering the arc-shaped pipe. When the organic wastewater is ejected at high speed from the arc-shaped pipe, a reaction force is generated, driving the rotating shaft to rotate around its axis, thereby creating a stirring effect in the mixing chamber. At the same time, the ozone generation and delivery unit continuously supplies ozone to the mixing chamber. Under the stirring action of the rotating shaft, the ozone and organic wastewater can come into full contact, greatly increasing the solubility of ozone in the organic wastewater. Multiple baffles set in the transition chamber constitute a vertical serpentine flow channel. The gas-liquid mixture rising from the mixing chamber meanders through the vertical serpentine flow channel. Due to the meandering design of the flow channel, the residence time of the gas-liquid mixture is significantly extended. This provides more reaction opportunities between ozone and organic wastewater, further promoting their mixing and reaction. The fully mixed ozone and organic wastewater then enter the reaction chamber, where, under the action of the catalyst reaction section, a series of complex and efficient chemical reactions are triggered. Ozone molecules preferentially adsorb onto the active sites on the catalyst surface. Under the catalytic action of the catalyst, ozone decomposes to generate highly oxidizing hydroxyl radicals. These hydroxyl radicals have extremely high oxidation potentials and can react non-selectively with various complex organic pollutants in organic wastewater. Under the strong oxidizing effect of hydroxyl radicals, the chemical bonds of organic pollutants gradually break, the organic molecular structure is destroyed, and they are gradually oxidized and decomposed into relatively simple small molecules, such as organic acids and aldehydes. As the reaction continues, these small molecules are further oxidized and eventually completely converted into harmless substances such as carbon dioxide and water. The treated water is discharged into a storage tank to achieve water resource recycling or discharge in compliance with standards. The significant advantage of this treatment system lies in its use of a rotating shaft stirring design and a vertical serpentine flow channel to effectively overcome the key challenge of low ozone solubility in wastewater in existing technologies. This not only significantly improves the utilization rate of ozone but also significantly enhances the reaction effect between ozone and organic wastewater, thereby greatly improving the treatment efficiency of organic wastewater and ensuring better water quality and treatment effect.

Detailed Implementation

[0026] The embodiments of this application will now be described in detail with reference to the accompanying drawings. Example

[0027] Please refer to Figures 1-4This application provides an ozone catalytic oxidation treatment system for organic wastewater, comprising: a vertical reaction tower 3, wherein a reaction chamber 301, a transition chamber 302, and a mixing chamber 303 are arranged sequentially from top to bottom inside the tower; a catalyst reaction section 11 is arranged in the reaction chamber 301; a plurality of baffles 14 are arranged in the transition chamber 302, forming a vertical serpentine flow channel; the top and bottom of the vertical serpentine flow channel are respectively connected to the reaction chamber 301 and the mixing chamber 303; wherein the reaction chamber 301 is connected to a water storage tank 8; and a mixing assembly, including a base 21, a rotating shaft 16, and a plurality of arc-shaped tubes 17, wherein the base 21 is disposed in the mixing chamber 301. Within 03, the aforementioned rotating shaft 16 is rotatably mounted on the aforementioned base 21. The aforementioned base 21 is provided with a first flow channel 22, and the aforementioned rotating shaft 16 is provided with a second flow channel 23 that is connected to the aforementioned first flow channel 22. The aforementioned first flow channel 22 and the aforementioned second flow channel 23 are both located on the central axis of the aforementioned rotating shaft 16. One end of any of the aforementioned arc-shaped tubes 17 is connected to the aforementioned second flow channel 23, and the other end is connected to the aforementioned mixing chamber 303. When at least one of the aforementioned arc-shaped tubes 17 sprays organic wastewater, it drives the aforementioned rotating shaft 16 to rotate. The organic wastewater supply assembly 1 is used to supply organic wastewater to the aforementioned first flow channel 22. The ozone generation and delivery unit 2 is used to deliver ozone to the aforementioned mixing chamber 303.

[0028] In the actual operation of the treatment system of this application, the organic wastewater supply component 1 continuously delivers organic wastewater to the first flow channel 22. The wastewater flows sequentially through the first flow channel 22 and the second flow channel 23 before entering the arc-shaped pipe 17. When the organic wastewater is ejected at high speed from the arc-shaped pipe 17, a reaction force is generated, driving the rotating shaft 16 to rotate around its axis, thereby creating a stirring effect in the mixing chamber 303. At the same time, the ozone generation and delivery unit 2 continuously supplies ozone to the mixing chamber 303. Under the stirring action of the rotating shaft 16, the ozone and organic wastewater can fully contact each other, greatly increasing the solubility of ozone in the organic wastewater. The multiple baffles 14 set in the transition chamber 302 constitute a vertical serpentine flow channel. The gas-liquid mixture rising from the mixing chamber 303 meanders through the vertical serpentine flow channel. Due to the meandering design of the flow channel, the residence time of the gas-liquid mixture is significantly extended. This provides more reaction opportunities between ozone and organic wastewater, further promoting their mixing and reaction. After thorough mixing, ozone and organic wastewater enter reaction chamber 301. Within chamber 301, the catalyst reaction section 11 triggers a series of complex and efficient chemical reactions. Ozone molecules preferentially adsorb onto the active sites on the catalyst surface. Under the catalytic action of the catalyst, ozone decomposes to produce highly oxidizing hydroxyl radicals. These hydroxyl radicals possess extremely high oxidation potentials and can react non-selectively with various complex organic pollutants in the wastewater. Under the strong oxidizing effect of the hydroxyl radicals, the chemical bonds of organic pollutants gradually break, the organic molecular structure is destroyed, and they are gradually oxidized and decomposed into relatively simple small molecules, such as organic acids and aldehydes. As the reaction progresses, these small molecules continue to be oxidized, eventually being completely converted into harmless substances such as carbon dioxide and water. The treated water is discharged into storage tank 8, achieving water resource recycling or meeting discharge standards. The significant advantage of this treatment system lies in its effective overcoming of the key challenge of low ozone solubility in wastewater in existing technologies through the stirring design of the rotating shaft 16 and the construction of a vertical serpentine flow channel. It not only significantly improves the utilization rate of ozone, but also significantly enhances the reaction effect between ozone and organic wastewater, thereby greatly improving the treatment efficiency of organic wastewater and ensuring better water quality and treatment effect after treatment.

[0029] In a preferred embodiment, a rotary joint 9 is provided at the junction of the first flow channel 22 and the second flow channel 23 to connect the two, so as to accommodate the relative rotation of the shaft 16 and the base 21.

[0030] In the above embodiments, the design of the rotary joint 9 ensures that the organic wastewater can flow stably from the first flow channel 22 to the second flow channel 23. Even if the rotating shaft 16 continues to rotate in the mixing chamber 303, it will not affect the transportation of wastewater, thus ensuring the continuity of the treatment system operation.

[0031] In a preferred embodiment, the system also includes an ultrasonic generator 19 and an ultrasonic transducer 20 disposed in the mixing chamber 303.

[0032] In the above embodiment, the ultrasonic generator 19 generates high-frequency electrical signals, while the ultrasonic transducer 20 converts these electrical signals into ultrasonic energy and transmits it into the mixing chamber 303. When the ultrasonic waves propagate in the mixture of organic wastewater and ozone, they induce cavitation. During the formation, growth, and collapse of cavitation bubbles, localized high-temperature and high-pressure environments, as well as intense shock waves and microjets, are generated. This not only promotes faster decomposition of ozone to produce highly oxidizing hydroxyl radicals but also significantly increases the contact area between ozone and organic wastewater, accelerating the dissolution of ozone in the wastewater and further enhancing the reactivity of ozone with organic pollutants.

[0033] In a preferred embodiment, the ozone generating and delivering unit 2 includes an oxygen cylinder 201 and an ozone generator 202 that cooperate with each other. The ozone outlet of the ozone generator 202 is connected to a nano-aeration disc 18, which is disposed at the bottom of the mixing chamber 303.

[0034] In the above embodiment, oxygen cylinder 201 provides a stable gas source for ozone generator 202, ensuring continuous ozone generation. Due to its special structure, the nano-aeration disc 18 can uniformly release ozone in the form of microbubbles to the bottom of mixing chamber 303. The microbubbles have a large specific surface area, significantly increasing the contact area between ozone and organic wastewater. During the upward diffusion process from the bottom, they thoroughly mix with the organic wastewater, greatly improving the ozone's dissolution efficiency in the wastewater.

[0035] In a preferred embodiment, a photocatalyst layer 15 is provided on the surface of any of the above-mentioned baffles 14; wherein, the above-mentioned vertical reaction tower 3 is provided with a transparent part 24, the transparent part 24 is opposite to the above-mentioned transition cavity 302, and an ultraviolet light irradiation lamp 10 is provided on the outer side of the transparent part 24 for irradiating the above-mentioned photocatalyst layer 15.

[0036] In the above embodiment, when organic wastewater enters the transition chamber 302 from the mixing chamber 303 and flows in the vertical serpentine flow channel, the photocatalyst layer 15 on the baffle plate 14 is activated under ultraviolet light irradiation, generating electron-hole pairs with strong oxidizing properties, initiating a photocatalytic oxidation reaction, and beginning to degrade some organic pollutants. Subsequently, the wastewater enters the reaction chamber 301, where the catalyst reaction section 11 promotes the decomposition of ozone to generate hydroxyl radicals, further oxidizing the remaining organic pollutants in the wastewater. This synergistic effect of photocatalysis and ozone catalytic oxidation, from the transition chamber 302 to the reaction chamber 301, treats organic wastewater in multiple stages and through multiple pathways, greatly improving the degradation efficiency of various organic pollutants, especially the removal effect of recalcitrant organic pollutants. It can effectively reduce the pollutant content in wastewater, significantly improve the treatment effect of organic wastewater, and make the treated water quality more likely to meet discharge standards.

[0037] As a preferred embodiment, the ultraviolet irradiation lamp 10 is provided with a protective cover 4.

[0038] In the above embodiments, the protective cover 4 provides protection for the ultraviolet irradiation lamp 10. It not only prevents impurities from adsorbing onto the surface of the ultraviolet irradiation lamp 10, but also prevents operators from accidentally coming into contact with the high-temperature ultraviolet tube during equipment operation, thus preventing burn accidents and greatly improving the safety of equipment operation.

[0039] In a preferred embodiment, any of the above-mentioned baffles 14 is provided with a heating element 13.

[0040] In the above embodiments, during the organic wastewater treatment process, the heating element 13 can moderately heat the wastewater passing through the baffle 14. Increasing the wastewater temperature within a certain range can accelerate molecular motion, promote ozone diffusion in the wastewater, and increase the probability of collisions between ozone and organic pollutants, thereby accelerating the reaction rate. Simultaneously, a suitable temperature helps enhance catalyst activity; both the photocatalyst on the baffle 14 and the catalyst reaction section 11 in the reaction chamber 301, with enhanced activity, can more efficiently catalyze the oxidation reaction, strengthening the decomposition effect on organic pollutants.

[0041] In a preferred embodiment, the organic wastewater supply assembly 1 includes a storage tank 101 and a transfer pump 102. The storage tank 101 is used to store organic wastewater, and the transfer pump 102 is used to transport the organic wastewater stored in the storage tank 101 to the first flow channel 22.

[0042] In the above embodiment, the transfer pump 102 can precisely control the flow rate and pressure of the organic wastewater according to the actual needs of the treatment system, and stably and efficiently transport the organic wastewater in the storage tank 101 to the first flow channel 22.

[0043] In a preferred embodiment, a water distributor 12 is provided at the position where the vertical serpentine flow channel connects to the reaction chamber 301.

[0044] In the above embodiment, the water distributor 12 can uniformly disperse the gas-liquid mixture, after being thoroughly mixed and preliminarily reacted in the vertical serpentine flow channel, into the reaction chamber 301. This ensures that all parts of the reaction chamber 301 receive the fluid to be treated with a relatively uniform composition, avoiding uneven local reactions. The uniformly distributed fluid can make more thorough contact with the catalyst reaction section 11 in the reaction chamber 301, allowing the catalyst to fully exert its effect and improving the efficiency and effectiveness of the ozone catalytic oxidation reaction.

[0045] In a preferred embodiment, the top of the reaction chamber 301 is sequentially connected to a demister 5, an ozone exhaust gas destroyer 6, and an explosion-proof fan 7.

[0046] In the above embodiments, the demister 5 effectively removes water mist carried in the reacted gas, preventing water mist from entering subsequent equipment and causing corrosion or affecting equipment performance, thus ensuring the purity of the gas. The ozone exhaust gas destroyer 6 decomposes unreacted ozone, converting it into harmless oxygen, preventing ozone emissions into the environment and causing air pollution, greatly improving the environmental friendliness of the entire treatment system. The explosion-proof fan 7 is responsible for safely discharging the treated gas; its explosion-proof design effectively prevents safety accidents caused by potentially flammable and explosive components in the gas, ensuring safe equipment operation. The coordinated operation of this entire system ensures the safe and stable operation of the treatment system and achieves environmentally friendly exhaust gas emissions, making the organic wastewater treatment process more complete and reliable.
