Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a device for comprehensive wastewater treatment based on advanced oxidation. Background Technology

[0002] With the accelerating pace of industrialization and urbanization, wastewater discharge is increasing daily. This wastewater contains a wide variety of pollutants, such as organic matter, heavy metal ions, nitrogen and phosphorus nutrients, etc. If discharged directly into the environment without effective treatment, it will cause serious damage to water bodies, soil, and ecosystems, threatening human health, the survival of aquatic organisms, and the sustainable use of water resources.

[0003] Advanced oxidation processes (AEs) are an emerging wastewater treatment technology. Their main principle is to oxidize and decompose pollutants in wastewater by generating highly oxidizing free radicals, such as ·OH radicals. ·OH radicals have extremely high oxidation potentials and can react rapidly and non-selectively with the vast majority of organic matter in wastewater, ultimately degrading it into carbon dioxide, water, and harmless inorganic ions.

[0004] Existing Fenton oxidation methods require the consumption of large amounts of chemical reagents, such as ferrous sulfate and hydrogen peroxide, and generate a large amount of iron sludge, making subsequent treatment difficult. Photocatalytic oxidation methods have low light energy utilization and slow reaction rates. Ozone has limited solubility in water, and its treatment effect is not ideal when used. Therefore, existing advanced oxidation methods for wastewater treatment equipment still need improvement. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a device for the comprehensive treatment of wastewater based on advanced oxidation methods.

[0006] The technical solution of the present invention is: a device for comprehensive treatment of wastewater based on advanced oxidation method, including a base, a frame slidably disposed on the base, a treatment tank disposed in the frame through a first mounting ring, an electric cylinder disposed on the base and whose output end is fixedly connected to the frame, an airbag disposed laterally between the frame and the base, an inlet valve pipe disposed at one end of the treatment tank, and an outlet valve pipe disposed at the other end of the treatment tank through a second mounting ring.

[0007] Both the first mounting ring and the second mounting ring are fixedly connected to the frame. Multiple air inlets are provided on the wall of the processing tank at the connection of the first mounting ring, and multiple water outlets are provided on the wall of the processing tank at the connection of the second mounting ring. The first mounting ring and the second mounting ring respectively have cavities that communicate with the air inlets and water outlets. A one-way valve is provided on the air inlet. The airbag passes through the frame and communicates with the cavity of the first mounting ring through the air outlet. A one-way air valve is provided on the air inlet of the airbag.

[0008] The cavity inside the second mounting ring is connected to the water outlet valve pipe; a transmission component is rotatably mounted on the frame, consisting of a worm gear and a gear arranged coaxially and vertically; a rack that meshes with the gear is mounted on the base on one side of the gear via a mounting plate; and the surface of the treatment tank is provided with a thread that can perform worm gear transmission with the worm gear.

[0009] The inlet valve pipe and the outlet valve pipe are connected by a pipe body and a circulation pump; the inside of the treatment tank is provided with multiple packing ring plates spaced apart along its length.

[0010] Note: Different packing rings can filter impurities of different particle sizes or properties, improving filtration efficiency. The circulation pump allows wastewater to circulate within the treatment tank, ensuring it undergoes multiple filtrations through the packing rings, further enhancing wastewater treatment quality.

[0011] Furthermore, each of the two end faces of the packing ring plate has several water passage holes, and along the direction from the inlet valve pipe to the outlet valve pipe of the treatment tank, the diameter of the water passage holes of each packing ring plate decreases sequentially, and each water passage hole is equipped with a check valve.

[0012] Explanation: Installing check valves on the packing rings helps maintain the specific filtration sequence of wastewater between the rings. During normal operation, wastewater can only pass through each packing ring sequentially from the inlet valve to the outlet valve. The check valves ensure this filtration sequence is not disrupted, allowing each packing ring to perform its intended filtration function, effectively filtering impurities of specific particle size or properties. The decreasing pore size design ensures finer filtration of the wastewater. The larger pore size packing rings at the beginning handle most of the coarse filtration, reducing the burden on the smaller pore size packing rings and minimizing clogging and damage caused by large impurities to the finer packing rings.

[0013] Furthermore, the packing ring plate is uniformly filled with activated carbon and photocatalyst; the longitudinal section of the treatment barrel is a ring structure, and the frame is equipped with an ultraviolet lamp column that can be embedded in the center of the ring structure. The packing ring plate and the inner wall of the treatment barrel are respectively provided with a light-transmitting layer, and the outer inner wall of the treatment barrel is a mirror layer.

[0014] Explanation: Activated carbon has a strong adsorption capacity, capable of adsorbing organic pollutants and odor substances in wastewater. Photocatalysts, under ultraviolet (UV) irradiation, generate highly oxidizing free radicals, such as hydroxyl radicals, thereby degrading organic matter in the wastewater. The treatment tank has a ring-shaped longitudinal section, with the UV lamp column embedded in the center of the ring structure. This layout ensures that UV light can fully irradiate the wastewater and photocatalyst inside the tank, preventing damage to the UV lamps from water flow impact. The light-transmitting layer on the inner wall of the tank facilitates UV penetration, ensuring effective activation of the photocatalyst. The mirrored layer on the outer inner wall reflects UV light, reducing its loss, enhancing light reflection, and improving UV utilization, thus enhancing the wastewater treatment effect. Through the synergistic effect of multiple mechanisms, wastewater is purified more efficiently.

[0015] Furthermore, the light-transmitting layer is made of polycarbonate, and the mirror layer is made of mirror-polished stainless steel.

[0016] Explanation: The polycarbonate light-transmitting layer has excellent light transmittance, allowing ultraviolet light and other rays to pass through efficiently, ensuring that the photocatalyst inside the treatment tank can be fully excited, thereby effectively carrying out the photocatalytic reaction to treat wastewater. At the same time, polycarbonate also has high strength and stability, maintaining structural integrity in the complex environment of wastewater treatment. The mirror-polished stainless steel material serves as a mirror layer, and its excellent reflective properties can effectively reflect ultraviolet rays, reducing ultraviolet light loss, improving the utilization rate of ultraviolet rays inside the treatment tank, and enhancing the effect of photocatalytic reaction. In addition, the stainless steel material has corrosion-resistant properties, can adapt to the chemical substances in the wastewater treatment environment, ensuring the long-term stability of the mirror layer's reflective function, and contributing to the continuous and efficient operation of the entire wastewater treatment equipment.

[0017] Furthermore, the treatment tank is equipped with multiple aeration pipes, each aeration pipe is connected to each air inlet in a one-to-one correspondence, the aeration pipes extend along the length of the treatment tank and penetrate each packing ring plate, multiple aeration holes are evenly distributed on the surface of the aeration pipes, and the aeration pipes are sealed to the packing ring plates.

[0018] Explanation: The aeration pipe injects air into the wastewater in the treatment tank, increasing the dissolved oxygen content. In advanced oxidation processes, sufficient dissolved oxygen helps promote the oxidation reaction, especially for some recalcitrant organic pollutants, which can be transformed into more easily treated substances, thus improving the wastewater treatment effect. The evenly distributed aeration holes on the surface of the aeration pipe allow air to form uniform bubbles in the wastewater. These bubbles agitate the wastewater as they rise, ensuring thorough mixing of the wastewater with the catalysts and oxidants in the treatment tank. This good mixing increases the contact opportunities between reactants, accelerates the reaction rate, and ensures the uniformity and efficiency of wastewater treatment.

[0019] Furthermore, the aeration pipe is rotatably and sealed to each packing ring plate. The aeration pipe corresponding to the position of the first mounting ring is provided with a toothed disc, and the aeration pipes located on both sides of the toothed disc are rotatably and sealed with air guide chambers. The air guide chambers are connected to the air inlet and the interior of the aeration pipe. The aeration pipe is provided with multiple stirring paddles. The side wall of the treatment tank is provided with a strip groove that allows the outer side of the toothed disc to pass through. The interior of the first mounting ring is provided with a toothed ring that can mesh with the toothed disc.

[0020] Explanation: The rotating toothed discs and agitators on both sides of the multiple air-guiding chambers agitate the wastewater in the treatment tank, ensuring thorough mixing of the wastewater with various treatment substances and improving reaction efficiency. The design connecting the air-guiding chambers, the inner wall of the treatment tank, and the agitator's vent pipe allows for the use of gas introduced through the air inlet and discharged through the vent pipe, providing aeration while agitating, further increasing the dissolved oxygen content of the wastewater and aiding in the oxidation reaction. The meshing connection between the toothed discs and the internal toothed ring of the first mounting ring allows the toothed discs to rotate along with the treatment tank, continuously agitating the agitator. This synergistic design ensures continuous mixing and aeration during wastewater treatment under various motion conditions, thereby improving the overall treatment effect of the wastewater treatment equipment.

[0021] Furthermore, the surface of the gear disc is provided with multiple water grooves.

[0022] Explanation: The water channel prevents the gear disc from being damaged by the water flow and reduces the pressure caused by the water flow. The water channel of the rotating gear disc can also play a role in turbulence.

[0023] Furthermore, valves for cleaning and maintenance are provided on the surface of the outlet valve pipe and the treatment tank; ring grooves are respectively provided on the outer wall of the treatment tank at the corresponding positions of the first mounting ring and the second mounting ring, and the inner surfaces of the first mounting ring and the second mounting ring are respectively provided with protrusions that are sealed and slidably engaged with the ring grooves.

[0024] Note: The valve allows for timely cleaning of impurities in the outlet valve pipe and inside the treatment tank after a period of use. It also enables timely maintenance of components such as the packing ring plate, facilitating the timely replenishment and replacement of the filled activated carbon and photocatalyst.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] The device of this invention uses an electric cylinder to drive the frame to slide back and forth on the base, a rack and pinion to drive the transmission component, and then a threaded engagement to drive the treatment tank to rotate forward and backward within the frame. This lateral and axial movement achieves efficient stirring of the wastewater, allowing pollutants in the wastewater to fully react with the catalyst. Multiple packing rings between the inlet and outlet valves repeatedly filter the wastewater, enhancing the purification effect. The relative movement between the frame and the base stretches and compresses the airbags, and the gas inside the airbags is transported into the treatment tank through pipes for aeration, thereby promoting the reaction and flocculation of pollutants and improving the wastewater purification efficiency. The circulation pump allows the wastewater to circulate within the treatment tank, ensuring that the wastewater undergoes multiple filtrations through the packing rings, further improving the quality of wastewater treatment.

Detailed Implementation

[0035] The present invention will now be described in more detail with reference to specific embodiments, so as to better demonstrate the advantages of the present invention.

[0036] Example 1: As Figures 1-4The device for comprehensive wastewater treatment based on advanced oxidation method is shown, including a base 1, a frame 2 slidably mounted on the base 1, a treatment tank 4 rotatably sealed within the frame 2 via a first mounting ring 3, an electric cylinder 5 mounted on the base 1 with its output end fixedly connected to the frame 2, two airbags 6 transversely mounted between the frame 2 and the base 1, an inlet valve pipe 7 mounted at one end of the treatment tank 4, and an outlet valve pipe 9 rotatably sealed at the other end of the treatment tank 4 via a second mounting ring 8; the outer walls of the treatment tank 4 at corresponding positions of the first mounting ring 3 and the second mounting ring 8 are respectively provided with annular grooves, and the inner surfaces of the first mounting ring 3 and the second mounting ring 8 are respectively provided with protrusions that are slidably engaged with the annular grooves.

[0037] The bottom of the frame 2 is provided with a slider, and the base 1 is provided with a guide rail that slides and engages with the slider;

[0038] Both the first mounting ring 3 and the second mounting ring 8 are fixedly connected to the frame 2. Multiple air inlets are provided on the wall of the treatment tank 4 located at the connection point of the first mounting ring 3, and multiple water outlets are provided on the wall of the treatment tank 4 located at the connection point of the second mounting ring 8. The first mounting ring 3 and the second mounting ring 8 each have cavities corresponding to the air inlets and water outlets, respectively. A one-way valve is provided on the air inlet. The airbag 6 passes through the frame 2 and communicates with the cavity of the first mounting ring 3 through its air outlet end. A one-way air valve is provided on the air inlet end of the airbag 6. The cavity inside the second mounting ring 8 is connected to the water outlet valve pipe 9.

[0039] like Figure 2 , 3 As shown, a transmission assembly 21 is rotatably mounted on the frame 2, consisting of a worm gear and a gear arranged coaxially and vertically. A rack 11 that meshes with the gear is mounted on the base 1 located on one side of the gear via a mounting plate. The surface of the processing barrel 4 is provided with a thread that can perform worm gear transmission with the worm gear.

[0040] like Figure 2 As shown, there are three transmission components 21, and the three transmission components 21 are arranged at intervals along the length of the treatment tank 4, avoiding the positions of the first mounting ring 3 and the second mounting ring 8; the inlet valve pipe 7 and the outlet valve pipe 9 are connected by a pipe body and a circulation pump.

[0041] like Figure 5 As shown, the treatment tank 4 has eight packing ring plates 41 spaced apart along its length; each of the two end faces of the packing ring plates 41 has five water passage holes, and along the direction from the water inlet valve pipe 7 to the water outlet valve pipe 9 of the treatment tank 4, the diameters of the water passage holes on the eight packing ring plates 41 are as follows: 200mm, 180mm, 170mm, 160mm, 150mm, 140mm, 135mm, and 130mm, respectively. Each water passage hole is equipped with a check valve.

[0042] The packing ring plate 41 is uniformly filled with activated carbon and photocatalyst; the longitudinal section of the treatment tank 4 is a ring structure, and the frame 2 is provided with an ultraviolet lamp column 22 that can be embedded in the center of the ring structure. The packing ring plate 41 and the inner wall of the treatment tank 4 are provided with a light-transmitting layer, and the outer inner wall of the treatment tank 4 is a mirror layer.

[0043] The light-transmitting layer is made of polycarbonate, and the mirror layer is made of mirror-polished stainless steel.

[0044] The treatment tank 4 is equipped with multiple aeration pipes 42. Each aeration pipe 42 is connected to each air inlet hole in a corresponding manner. The aeration pipe 42 extends along the length of the treatment tank 4 and passes through each packing ring plate 41. Multiple aeration holes are evenly distributed on the surface of the aeration pipe 42, and the aeration pipe 42 is sealed to the packing ring plate 41.

[0045] Both the outlet valve pipe 9 and the treatment tank 4 are equipped with valves for cleaning and maintenance; the inlet valve pipe 7 is connected to the pipe into which wastewater is input via a rotating sealing connector.

[0046] It should be noted that this embodiment also includes a power supply and a controller, and the power supply, controller, packing ring plate 41, air bag 6, electric cylinder 5, ultraviolet lamp column 22, aeration pipe 42, circulation pump, activated carbon, and photocatalyst are all commercially available products, and will not be described in detail here.

[0047] The electric cylinder 5, the ultraviolet lamp column 22, and the circulation pump are all electrically connected to the power supply and the controller, respectively.

[0048] The working principle of this embodiment is as follows:

[0049] Wastewater enters the treatment tank 4 through the inlet valve pipe 7. During the inflow process, due to the multiple packing ring plates 41 arranged longitudinally inside the treatment tank 4, the wastewater first passes through the first packing ring plate. Since the packing ring plate 41 is equipped with a check valve, it prevents wastewater backflow. Furthermore, the average pore size of the filter holes decreases sequentially along the transverse direction from the inlet valve pipe 7 to the outlet valve pipe 9 of the treatment tank 4. This initially filters out larger particles of impurities, gradually reducing the wear and tear on the packing ring plates 41. Simultaneously, the packing ring plates 41 are uniformly filled with activated carbon and photocatalysts. The activated carbon adsorbs organic matter, pigments, and other pollutants in the wastewater, while the photocatalyst participates in advanced oxidation reactions under subsequent ultraviolet irradiation, initially purifying the wastewater. At this time, the reciprocating extension and retraction of the electric cylinder 5 adjusts the position of the frame 2 on the base 1. Stable movement is achieved by the sliding engagement of the slider at the bottom of the frame 2 with the guide rail on the base 1, thereby promoting the agitation of the water flow within the treatment tank 4, promoting the transverse movement of the water flow, and improving the efficiency of its interaction with the packing ring plates. The airbag 6 passes through the frame 2 and is connected to the cavity via a pipe. A one-way air inlet valve is provided on the surface of the airbag 6 to ensure that gas is supplied to the aeration pipe 42 when the airbag 6 is stretched or compressed, promoting the oxidation reaction of the wastewater. The inlet valve pipe 7 and the outlet valve pipe 9 are connected to a circulation pump via a pipe body, allowing untreated wastewater to circulate and be purified within the treatment tank 4. Ring grooves are respectively provided on the outer wall of the treatment tank 4 at the corresponding positions of the first mounting ring 3 and the second mounting ring 8. The inner surfaces of the first mounting ring 3 and the second mounting ring 8 are respectively provided with protrusions that slide and seal with the ring grooves, ensuring sealing performance and preventing wastewater leakage.

[0050] The frame 2 is equipped with an ultraviolet lamp column 22 that can be embedded in the center of the ring structure, ensuring light while avoiding damage to components and circuits caused by water impact and immersion as in conventional methods. The inner wall of the treatment tank 4 has a light-transmitting layer made of polycarbonate material to ensure good light transmission, while the outer inner wall of the treatment tank 4 is a mirror layer made of mirror-polished stainless steel to reflect light. Under the irradiation of the ultraviolet lamp column 22, the photocatalyst in the wastewater is activated, triggering advanced oxidation reactions and generating highly oxidizing free radicals, such as hydroxyl radicals. These free radicals can decompose recalcitrant organic matter in the wastewater, further purifying it.

[0051] During the water intake and circulation processes, the treatment tank 4 rotates due to the threaded connection between the transmission component 21, the rack 11, and the treatment tank 4. This rotation further agitates the wastewater, ensuring thorough mixing of the wastewater, oxygen, and photocatalyst, thus improving reaction efficiency. After multiple cycles, the treated wastewater is finally discharged through the outlet valve pipe 9. The quality of the discharged wastewater is improved due to the multiple filtration processes of the packing ring plate 41 and the advanced oxidation reaction. Both the outlet valve pipe 9 and the surface of the treatment tank 4 are equipped with valves for cleaning and maintenance, facilitating regular cleaning and maintenance of the equipment, as well as the replacement and replenishment of activated carbon and photocatalyst.

[0052] Example 2: This example differs from Example 1 in that, as Figure 6 As shown, the aeration pipe 42 is rotatably and sealed to each packing ring plate 41. The aeration pipe 42 corresponding to the position of the first mounting ring 3 is provided with a toothed disc 44, and the aeration pipe 42 located on both sides of the toothed disc 44 is rotatably and sealed with an air guide chamber 43. The air guide chamber 43 is connected to the air inlet and the interior of the aeration pipe 42. The aeration pipe 42 is provided with multiple stirring paddles 45. The stirring paddle 45 has a vent pipe connected to the interior of the aeration pipe 42, and the stirring paddle 45 has multiple aeration holes connected to the vent pipe. The side wall of the treatment tank 4 is provided with a strip groove that allows the outer side of the toothed disc 44 to pass through. The interior of the first mounting ring 3 is provided with a toothed ring 31 that can mesh with the toothed disc 44. The cavity in the first mounting ring 3 that is connected to the air inlet of the treatment tank 4 and the cavity of the strip groove and the toothed ring are not connected.

[0053] Example 3: This example differs from Example 1 in that, as Figure 7 As shown, the surface of the toothed disc 44 is provided with multiple water passage grooves 441.

[0054] Example 4: The difference between this example and Example 1 is that the outer sides of the toothed disc 44 and the strip groove are provided with a mesh shell to protect the normal rotation of the toothed disc 44, and the stirring paddle 45 can rotate through the mesh shell.
