Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a strong oxidizing wastewater treatment equipment and process. Background Technology

[0002] Rural sewage, categorized by source, includes domestic sewage and industrial wastewater. Domestic sewage includes wastewater from toilets, kitchens, and washing facilities, while industrial wastewater includes wastewater from livestock farming and agricultural product processing. The influx of industrial wastewater often makes the sewage system more complex and demands more sophisticated treatment processes.

[0003] Strong oxidation technologies (such as ozone oxidation) can non-selectively oxidize and decompose organic matter (such as pesticides, antibiotics, and endocrine disruptors) that are difficult to treat by traditional processes by generating highly active free radicals (such as ·OH), significantly reducing the toxicity of wastewater, and are highly adaptable to water quality fluctuations, making them suitable for the characteristics of rural wastewater discharge.

[0004] These substances can chemically react with organic matter in wastewater, gradually degrading it into simple inorganic substances such as carbon dioxide (CO2), water (H2O), and inorganic salts. Simultaneously, these strong oxidants can oxidize pollutants dissolved in water into substances that are insoluble in water and easily separated from it, thereby further purifying the wastewater and reducing its COD value.

[0005] In the prior art, such as the patent document with announcement number CN118359346B, a high COD wastewater treatment device and treatment method are disclosed. It also discloses that by setting a pretreatment mechanism, the ozone gas sprayed from the second nozzle comes into contact with the wastewater falling on the surface of the conical heating plate, and the ozone can remove reducing substances in the wastewater.

[0006] While existing technologies disclose solutions for treating wastewater using multi-component ion-oxidizing gases, in practical applications, to improve the oxidation capacity of multi-component ion-oxidizing gases, it is necessary to set up a multi-component ion-oxidizing gas catalyst to work in synergy with it. Since the multi-component ion-oxidizing gas catalyst is a particulate material, it is easy for it to accumulate at the wastewater outlet under the action of water flow. This results in a short contact time between the wastewater and the multi-component ion-oxidizing gas and the catalyst, leading to poor catalytic effect. Summary of the Invention

[0007] The purpose of this invention is to provide a strong oxidizing wastewater treatment device and process, solving the following technical problems:

[0008] Multi-component ion oxidation gas catalysts tend to accumulate at the wastewater outlet under the influence of water flow. This results in insufficient contact time between the wastewater and the multi-component ion oxidation gas catalyst, leading to poor wastewater treatment performance.

[0022] A treatment process for a strong oxidizing wastewater treatment device, applied to the aforementioned strong oxidizing wastewater treatment device, includes the following steps:

[0023] The wastewater to be treated is first transported to a sedimentation tank for static sedimentation.

[0024] After a preset set time for sedimentation, the water pump discharges the wastewater in the sedimentation tank into the water tank through the water delivery pipe;

[0025] After the wastewater is discharged into the water tank, it enters the treatment tank through the drain outlet;

[0026] The ozone delivery module delivers ozone to the first gas pipe, and then discharges it into the treatment chamber through the first gas hole. The ozone catalyst particles interact with the ozone gas in the wastewater to treat the wastewater.

[0027] After processing, the first lifting unit drives the first sealing plate to descend and separate from the first filter plate, allowing the wastewater in the treatment chamber to be discharged through the first filter holes.

[0028] The beneficial effects of this invention are:

[0029] (1) In this invention, ozone catalyst particles are pre-stored in the treatment chamber. After the sewage is discharged into the water tank, it can enter the treatment tank through the drain under gravity. Then, the ozone is transported to the first gas pipe through the ozone delivery module. Finally, it can be discharged into the treatment chamber through the first gas hole. The ozone catalyst particles interact with ozone gas in the sewage, promoting the oxidation efficiency of the hydroxyl radicals generated by them, or forming metal complexes with organic matter and enhancing their redox ability, thereby accelerating the degradation of organic matter in the sewage. This invention can effectively reduce the COD value of sewage in the pretreatment stage.

[0030] (2) In the initial state, the first lifting part drives the first sealing plate to fit tightly with the first filter plate, thereby achieving the effect of sealing the first filter hole. After the sewage is treated in the treatment tank, the first lifting part drives the first sealing plate to descend and separate from the first filter plate, so that the sewage in the treatment chamber can pass through the first filter hole and be discharged. Accordingly, when the sewage is treated, the contact time between the first sealing plate and the first filter plate can be adjusted by the first lifting part to prolong the reaction time between the sewage and ozone and ozone catalyst particles, thereby further improving the sewage treatment effect.

[0031] (3) In the initial state, the second sealing plate is also in the state of closing the drain outlet. When the sewage is discharged into the water tank, the second sealing plate is driven to rise to a preset height by the second lifting part so that the water in the water tank can enter the treatment chamber through the drain outlet. When the water in the treatment chamber is full, the second sealing plate is driven to close the drain outlet again by the second lifting part. Accordingly, when the sewage entering the treatment chamber is treated, the treatment chamber can be sealed by the first sealing plate and the second sealing plate. Since no ozone catalyst particles are set in the water tank, when the ozone delivery module delivers ozone to the treatment chamber, ozone is prevented from entering the water tank through the drain outlet. At the same time, when the sewage is treated, the first sealing plate is driven to fall by the first lifting part so that the sewage in the treatment chamber can be discharged through the first filter hole, while the water in the water tank will not be discharged from the drain outlet.

[0032] (4) In the initial state, the second filter plate is in a horizontal state. As the second filter plate moves from the through groove to the outside of the water tank, the second guide wheel contacts the second inclined guide plate. As the second filter plate continues to move, the second guide wheel rises under the limiting action of the second inclined guide plate, thereby driving the second filter plate to rotate 180 degrees. At this time, the filter tank is downward so as to discharge the impurity particles in the filter tank. As the second guide wheel contacts the zigzag plate, it can drive the second filter plate to swing back and forth to achieve the vibration effect, so as to fully throw out the impurity particles in the filter tank. Correspondingly, when the second filter plate resets to the water tank, the fourth spring can synchronously drive each component to reset. The present invention does not need to use other servo drive equipment to clean the impurities in the filter tank. The treatment box can automatically clean the impurities in the filter tank once in a water treatment process, which not only reduces the cost, but also avoids the clogging of the second filter hole.

Detailed Implementation

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Example 1

[0047] Please see Figures 1-3 As shown, the present invention is a strong oxidizing wastewater treatment device, including a sedimentation tank 1 for collecting wastewater, and a sediment collection tank 101 at the bottom of the sedimentation tank 1; specifically, in this embodiment, the wastewater to be treated can be first transported to the sedimentation tank 1 for static sedimentation. During the sedimentation process, flocculants can be added to the sedimentation tank 1 to improve the sedimentation efficiency of solid impurities in the wastewater. The sedimented impurities are collected in the collection tank 101.

[0048] In this embodiment, a drain pipe 102 is provided at the bottom of the collection tank 101, and a drain valve is provided at the drain pipe 102 to discharge the deposited solid impurities.

[0049] A water supply pipe 103 is provided on one side of the sedimentation tank 1 to discharge the settled wastewater. Specifically, in this embodiment, a water pump can be installed on the sedimentation tank 1. After a preset sedimentation time, the water pump can discharge the wastewater in the sedimentation tank 1 through the water supply pipe 103.

[0050] As a further embodiment, a water tank 2 is provided on one side of the sedimentation tank 1, and the end of the water supply pipe 103 extends to the water tank 2. Several sets of drainage outlets 202 are opened at equal intervals on the bottom of the water tank 2, and each drainage outlet 202 is connected to the treatment box 3 fixedly arranged at the bottom of the water tank 2.

[0051] Specifically, in this embodiment, the drainage outlet 202 is arranged in three sets, but four or five sets can also be set. This embodiment does not limit the specific number of sets, as long as it meets the actual sewage treatment needs.

[0052] Please see Figure 3 and Figure 4 A first filter plate 801 is fixedly arranged at the bottom of the treatment box 3. First filter holes 802 are evenly distributed on the first filter plate 801. A first air pipe 803 is fixedly arranged on the first filter plate 801 and is connected to an ozone delivery module for inputting ozone gas into the first air pipe 803. Several sets of first air holes 804 are evenly distributed on the first air pipe 803. The outer side of the first air pipe 803, the treatment box 3, and the first filter plate 801 enclose a treatment cavity 301 for storing ozone catalyst particles. Specifically, this embodiment... In this embodiment, ozone catalyst particles are pre-stored in the treatment chamber 301. After the wastewater is discharged into the water tank, it can enter the treatment tank 3 through the drain outlet 202 under the action of gravity. Then, the ozone is transported to the first gas pipe 803 through the ozone delivery module, and finally discharged into the treatment chamber 301 through the first gas hole 804. The ozone catalyst particles interact with ozone gas in the wastewater, promoting the oxidation efficiency of the hydroxyl free radicals generated by them, or forming metal complexes with organic matter and enhancing their redox capacity, thereby accelerating the degradation of organic matter in the wastewater.

[0053] It should be noted that the pore size of the first filter hole 802 in this embodiment needs to be smaller than the particle size of the ozone catalyst particles in order to prevent the ozone catalyst particles from being discharged through the first filter hole 802.

[0054] Furthermore, the first vent 804 in this embodiment is equipped with a one-way valve limited to exhaust to prevent sewage in the treatment chamber 301 from flowing back into the first vent pipe 803. Correspondingly, when ozone gas is discharged from the first vent 804, an aeration effect can be achieved, blowing the ozone catalyst particles in the treatment chamber 301 away from the first filter plate 801 to prevent the ozone catalyst particles from always accumulating at the first filter plate 801, so that they can fully contact the sewage. This embodiment can further improve the oxidation effect and efficiency of sewage.

[0055] For further information, please refer to... Figures 4-5 The bottom of the treatment tank 3 is also provided with a first sealing plate 302 for sealing the first filter plate 801. The first sealing plate 302 is connected to a first lifting part that drives it to rise and fall. It can be explained that in the initial state, the first lifting part drives the first sealing plate 302 to fit tightly against the first filter plate 801, thereby achieving the effect of sealing the first filter hole 802. After the sewage is treated in the treatment tank 3, the first sealing plate 302 is driven to fall by the first lifting part and separate from the first filter plate 801, so that the sewage in the treatment chamber 301 can pass through the first filter hole 802 and be discharged. Accordingly, in this embodiment, when the sewage is treated, the contact time between the first sealing plate 302 and the first filter plate 801 can be adjusted by the first lifting part to prolong the reaction time of the sewage with ozone and ozone catalyst particles, thereby further improving the sewage treatment effect.

[0056] In addition, in this embodiment, a liquid level sensor can be installed in the water tank 2 to monitor the water depth in the water tank 2 in real time. When the water level is less than a preset threshold, the water pump can be started to replenish water into the water tank 2.

[0057] Example 2

[0058] Based on Example 1, please refer to Figures 2-4The water tank 2 is also equipped with several sets of second sealing plates 203 for sealing the drain outlet 202. The second sealing plates 203 are connected to a second lifting part that drives them to rise and fall. It can be noted that in this embodiment, in the initial state, the second sealing plates 203 are also in a state of sealing the drain outlet 202. When sewage is discharged into the water tank 2, the second lifting part drives the second sealing plates 203 to rise to a preset height, so that the water in the water tank 2 can enter the treatment chamber 301 along the drain outlet 202. When the treatment chamber 301 is full of water, the second lifting part drives the second sealing plates 203 to seal the drain outlet 202 again. Accordingly, in this embodiment, when treating wastewater entering the treatment chamber 301, the treatment chamber 301 can be sealed by the first sealing plate 302 and the second sealing plate 203. Since no ozone catalyst particles are placed in the water tank 2, after the ozone delivery module delivers ozone to the treatment chamber 301, ozone is prevented from entering the water tank 2 through the drain outlet 202. At the same time, after the wastewater treatment is completed, the first sealing plate 302 is lowered only by the first lifting part, so that the wastewater in the treatment chamber 301 can be discharged through the first filter hole 802, while the water in the water tank 2 will not be discharged from the drain outlet 202 (see reference). Figure 6 ).

[0059] In this embodiment, after the wastewater is discharged into water tank 2, in order to further filter the particulate impurities in the wastewater that have not been completely settled, please refer to [link to relevant documentation]. Figures 2-4 as well as Figure 7 A second filter plate 209 is embedded at the drain outlet 202. A filter groove 211 is opened on the second filter plate 209, and second filter holes 210 are evenly opened at the bottom of the filter groove 211. Specifically, when the sewage in the water tank 2 is discharged to the treatment tank 3, the impurity particles in the sewage can be filtered through the second filter holes 210, so that the impurity particles can be temporarily stored in the filter groove 211 to avoid entering the treatment tank 3.

[0060] Correspondingly, the pore size of the second filter hole 210 in this embodiment is also smaller than the particle size of the ozone catalyst particles, so that the ozone catalyst particles in the treatment chamber 301 will not enter the water tank 2, thus achieving an effective isolation effect.

[0061] Please see Figures 4-5The ozone delivery module includes a second air pipe 805 slidably arranged in the first air pipe 803. The second air pipe 805 is slidably attached to the pipe wall of the first air pipe 803. The second air pipe 805 is evenly provided with several sets of second air holes 8 corresponding to the first air holes 804. The second air pipe 805 slidably passes through the through hole opened on the first filter plate 801 and is fixed to the first sealing plate 302. The bottom of the first sealing plate 302 is fixedly provided with a lifting pipe 403 communicating with the second air pipe 805. The ozone delivery module also includes an air pump 4 fixed to the bottom of the water tank 2. One end of the air pump 4 is connected to the ozone storage tank, and the other end is connected to the main air pipe 401. The main air pipe 401 is provided with several sets of branch air pipes 402. The end of each lifting pipe 403 away from the first sealing plate 302 is slidably inserted into the branch air pipe 402. Specifically, the pipe wall of the lifting pipe 403 is slidably attached to the pipe wall of the branch air pipe 402.

[0062] It should be noted that in this embodiment, when transporting ozone, the air pump 4 can be started. The air pump 4 transports the ozone in the ozone storage tank to the main air pipe 401, and then through the branch air pipe 402 and the riser pipe 403 to the second air pipe 805. At this time, the first air hole 804 and the second air hole 8 are in a connected state, and the ozone can pass through the second air hole 8 and the first air hole 804 in sequence and be discharged into the processing chamber 301. Correspondingly, when the first sealing plate 302 separates from the first filter plate 801, the first filter plate 801 simultaneously drives the second air pipe 805 to move downward a certain distance. At this time, the first air hole 804 and the second air hole 8 are in a misaligned separation state to prevent ozone from being discharged from the air hole.

[0063] In this embodiment, please refer to Figures 2-5Two adjacent sets of first sealing plates 302 are fixed by first U-shaped frames 303. First L-shaped brackets 305 are fixedly arranged at the bottom of the first sealing plates 302 at both ends. The first L-shaped brackets 305 are slidably sleeved on the first guide rods 304. The first guide rods 304 are fixed to the processing box 3. A first spring 306 is provided on the first guide rods 304. One end of the first spring 306 is fixed to the first L-shaped bracket 305, and the other end is fixed to the end of the first guide rod 304. Each first U-shaped frame 303 is provided with a first push plate 602, which is connected to the first lifting part. It can be noted that in the initial state, based on the first spring 306... The first sealing plate 302 can be brought into contact with the first filter plate 801 by the first L-shaped bracket 305. When it is necessary to drive the first sealing plate 302 to separate from the first filter plate 801, the first push plate 602 is located above the first U-shaped frame 303. The first push plate 602 is driven to descend by the first lifting part. During the descent of the first push plate 602, the first U-shaped frame 303 can be driven to descend. The first U-shaped frame 303 can drive each first sealing plate 302 to descend synchronously. The first spring 306 is stretched to generate elastic force. When the first push plate 602 rises, it can drive the first sealing plate 302 to automatically reset.

[0064] Two sets of adjacent second sealing plates 203 are fixed by second U-shaped frames 207. Second L-shaped brackets 204 are fixedly arranged on the second sealing plates 203 at both ends. The second L-shaped brackets 204 are slidably sleeved on the second guide rods 205. The second guide rods 205 are fixed to the water tank 2. A second spring 206 is provided on the second guide rods 205. One end of the second spring 206 is fixed to the second L-shaped bracket 204, and the other end is fixed to the end of the second guide rod 205. A second push plate 607 is provided below each second U-shaped frame 207. The second push plate 607 is connected to the second lifting part. In the initial state, based on the setting of the second spring 206... The second sealing plate 203 can be brought into contact with the second filter plate 209 by the second L-shaped bracket 204. When it is necessary to drive the second sealing plate 203 to separate from the second filter plate 209, the second push plate 607 is located below the second U-shaped frame 207. The second push plate 607 is driven to rise by the second lifting part. During the rise of the second push plate 607, the second U-shaped frame 207 can be driven to rise. The second U-shaped frame 207 can drive each second sealing plate 203 to rise synchronously. The second spring 206 is stretched to generate elastic force. When the second push plate 607 falls, the second sealing plate 203 can be automatically reset synchronously.

[0065] Specifically, an installation plate 6 is fixedly arranged on one side of the water tank 2, and a lifting mechanism is fixedly arranged on one side of the installation plate 6. The driving end of the lifting mechanism is fixed to the lifting plate 601. The first lifting part includes a connecting frame fixed to the bottom of the lifting plate 601, and the connecting frame is fixed to the first push plate 602. The second lifting part includes a lifting frame 606 fixed to the top of the lifting plate 601, and each second push plate 607 is fixed to the lifting frame 606. It can be noted that in this embodiment, when adjusting the position of the first sealing plate 302 and the second sealing plate 203, the lifting plate 601 can be driven to rise and fall first through the lifting mechanism. The lifting plate 601 can then drive the first push plate 602 to rise and fall through the connecting frame and drive the second push plate 607 to rise and fall through the lifting frame 606. In this embodiment, one set of lifting mechanisms can realize the adjustment of the first push plate 602 or the second push plate 607, which effectively reduces the production cost.

[0066] Furthermore, the lifting mechanism in this embodiment can be a screw and nut transmission mechanism or a synchronous belt transmission mechanism. This embodiment does not limit this to any particular type, as long as it satisfies the requirement of driving the lifting plate 601 to rise and fall in the vertical direction.

[0067] As a further embodiment, in order to facilitate the effective discharge of impurity particles from the filter tank 211 and avoid clogging of the second filter hole 210, please refer to... Figure 3 and Figure 7 The bottom of the water tank 2 has a through groove 208 for sliding the second filter plate 209. Please refer to [link / reference]. Figures 8-10The second filter plate 209 is fixed to the support shaft 707 on one side, and the other end of the support shaft 707 is rotatably connected to the vertical guide plate 701 arranged on one side of the water tank 2. The top of the vertical guide plate 701 is fixed to the first inclined guide plate 7, which is inclined towards the water tank 2. A third guide rod 702 is fixedly arranged on the outside of the water tank 2. The third guide rod 702 is slidably inserted into the vertical guide plate 701. A third spring 703 is provided on the third guide rod 702. One end of the third spring 703 is fixed to the vertical guide plate 701, and the other end is fixed to the water tank 2. A limiting frame 603 is also fixedly arranged on the lifting plate 601. Several sets of limiting plates 604 are fixedly arranged on the limiting frame 603 towards the water tank 2. The end of the limiting plate 604 is rotatably arranged with a first guide wheel 605. It can be noted that when the water in the treatment chamber 301 is completely stored... After completion, as the lifting mechanism drives the lifting plate 601 to descend, the lifting plate 601 drives the first guide wheel 605 to descend through the limiting frame 603 and the limiting plate 604. When the second sealing plate 203 contacts the second filter plate 209, the first guide wheel 605 just moves to contact the first inclined guide plate 7. As the first guide wheel 605 continues to descend, it can push the vertical guide plate 701 to move towards the water tank 2. The vertical guide plate 701 pushes the second filter plate 209 to slide along the through groove 208 to the outside of the water tank 2 through the support shaft 707, so as to facilitate the processing of impurity particles stored in the filter tank 211. When the lifting plate 601 descends again, it can drive the first sealing plate 302 to separate from the first filter plate 801. Correspondingly, when the lifting plate 601 is driven to rise, the third spring 703 can drive the components to reset.

[0068] In this embodiment, after the second filter plate 209 is pushed out, in order to automatically collect impurities in the filter tank 211, a first gear 708 is fixedly arranged on the support shaft 707, a fourth guide rod 711 is fixedly arranged on the side of the vertical guide plate 701 facing the water tank 2, a slide block 710 is slidably sleeved on the fourth guide rod 711, a fourth spring 712 is provided on the fourth guide rod 711, one end of the fourth spring 712 is fixed to the slide block 710, and the other end is fixed to the bottom end of the fourth guide rod 711. One side of the slide block 710 is fixed to the rack 709, the rack 709 meshes with the gear 708, and a second guide wheel 706 is rotatably arranged on the other side of the rack 709. A second inclined guide plate 704 is fixed on one side of the bottom of the water tank 2, and the side of the second inclined guide plate 704 facing the water tank 2 is fixed to the curved plate 705. It can be noted that, initially, the second filter plate 209 is in a horizontal state. As the second filter plate 209 moves from the through groove 208 to the water tank 2... After the outer side, the second guide wheel 706 contacts the second inclined guide plate 704. As the second filter plate 209 continues to move, the second guide wheel 706 rises under the limiting action of the second inclined guide plate 704, thereby driving the second filter plate 209 to rotate 180 degrees. At this time, the filter tank 211 is downward so as to discharge the impurity particles in the filter tank 211. As the second guide wheel 706 contacts the zigzag plate 705, it can drive the second filter plate 209 to swing back and forth to achieve the vibration effect, so as to fully throw out the impurity particles in the filter tank 211. Correspondingly, when the second filter plate 209 returns to the water tank 2, the fourth spring 712 can synchronously drive each component to return to the original position. In this embodiment, it is not necessary to use other servo drive equipment to clean the impurities in the filter tank 211. The treatment box 3 can automatically clean the impurities in the filter tank 211 once in a water treatment process, which not only reduces the cost, but also avoids the clogging of the second filter hole 210.

[0069] In addition, please see Figures 1-3 A collection box 201 for collecting impurities is also fixed on the outside of the water tank 2. When impurities are discharged from the filter tank 211, they can automatically fall into the collection box 201 for collection.

[0070] The bottom of the water tank 2 is also equipped with a water storage tank 5 for collecting the treated wastewater so that it can be transported to the next treatment process.

[0071] A treatment process for a strong oxidizing wastewater treatment device includes the following steps:

[0072] Please see Figures 1-5 S1. The wastewater to be treated is first transported to sedimentation tank 1 for static sedimentation.

[0073] S2. After the preset sedimentation time, the water pump discharges the sewage in the sedimentation tank 1 into the water tank 2 through the water pipe 103;

[0074] S3. After the sewage is discharged into the water tank, it enters the treatment tank 3 through the drain outlet 202;

[0075] S4. The ozone delivery module delivers ozone to the first gas pipe 803 and discharges it into the treatment chamber 301 through the first gas hole 804. The ozone catalyst particles interact with the ozone gas in the sewage to treat the sewage.

[0076] Please see Figure 6 S5. After the treatment is completed, the first lifting part drives the first sealing plate 302 to descend and separate from the first filter plate 801, and the sewage in the treatment chamber 301 can be discharged through the first filter hole 802.
