Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, and in particular to a strong oxidation wastewater treatment device and process. Background Art

[0002] Strong oxidation medical wastewater treatment is a method of using strong oxidants to oxidize and decompose pollutants in medical wastewater to purify the wastewater and reduce its pollution to the environment. This treatment method is of great significance in the field of medical wastewater treatment because it can effectively remove difficult-to-degrade organic matter, toxic substances, and substances that cause color and odor in wastewater.

[0003] Strong oxidants such as ozone, hydrogen peroxide (H2O2), chlorine dioxide (ClO2), etc. have extremely strong oxidizing ability. They can react chemically with organic matter in wastewater and gradually degrade it into simple inorganic matter, such as carbon dioxide (CO2), water (H2O) and inorganic salts. At the same time, these strong oxidants can also oxidize pollutants dissolved in water into substances that are insoluble in water and easy to separate from water, thereby further purifying wastewater to reduce the COD value of wastewater.

[0004] In the prior art, for example, the patent document with the announcement number CN118359346B discloses a high COD wastewater treatment device and treatment method, and also discloses that by providing a pretreatment mechanism, the ozone gas sprayed from the second nozzle is blown into contact with the wastewater falling on the surface of the conical heating plate, and the ozone can remove the reducing substances in the wastewater;

[0005] Although the prior art discloses a technical solution for treating wastewater using multi-ion oxidizing gas, in actual application, in order to improve the oxidizing ability of the multi-ion oxidizing gas, it is also necessary to set up a multi-ion oxidizing gas catalyst to cooperate with it. Since the multi-ion oxidizing gas catalyst is a granular substance, it is easy for the multi-ion oxidizing gas catalyst to gather at the wastewater outlet under the action of water flow, which will cause the contact time between the wastewater and the multi-ion oxidizing gas and the multi-ion oxidizing gas catalyst to be too short, resulting in poor catalytic effect. Summary of the invention

[0032] Beneficial effects of the present invention:

[0033] (1) The present invention stores a preset amount of multi-ion oxidizing gas catalyst particles in the treatment chamber. When wastewater is input into the treatment barrel through the wastewater inlet pipe, the wastewater first enters the treatment chamber through the filter holes of the filter plate at the top of the treatment chamber. During this process, the multi-ion oxidizing gas is transported to the treatment chamber through the gas input module. The multi-ion oxidizing gas catalyst interacts with the multi-ion oxidizing gas in the wastewater to promote the oxidation efficiency of hydroxyl radicals generated by the multi-ion, or forms a metal complex with organic matter and enhances its redox ability, thereby accelerating the degradation of organic matter in the wastewater;

[0034] (2) In the process of wastewater treatment, the present invention can temporarily store the wastewater to be treated in the treatment chamber and treat it, and external water cannot be input, thereby achieving an isolation effect. Therefore, by controlling the lifting state of the first sealing plate and the second sealing plate by the lifting module, the contact time between the wastewater and the multi-ion oxidizing gas and the multi-ion oxidizing gas catalyst can be adjusted, thereby further improving the wastewater treatment effect;

[0035] (3) The multi-ion oxidizing gas of the present invention is only input when the first sealing plate and the second sealing plate are both in a state of sealing the filter plate. On the one hand, it can avoid the waste of the multi-ion oxidizing gas. On the other hand, when the multi-ion oxidizing gas is input, since the filter plates on both sides are sealed, the pressure in the treatment chamber will increase with the input of the multi-ion oxidizing gas. According to Henry's law, the solubility of the multi-ion oxidizing gas will increase with the increase of pressure. The increase of solubility helps to improve the mass transfer rate and utilization efficiency of the multi-ion oxidizing gas, thereby improving the wastewater treatment efficiency.

DETAILED DESCRIPTION

[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] Example 1

[0048] See also Figure 1 As shown, the present invention is a strong oxidation wastewater treatment device, comprising a treatment barrel 1; specifically, the treatment barrel 1 of this embodiment is a cylindrical structure as a whole, and its top is closed and the bottom is provided with an opening.

[0049] A wastewater inlet pipe 102 is provided on the treatment barrel 1 to transport wastewater into the treatment barrel 1; specifically, the wastewater inlet pipe 102 is connected to a pump body for transporting wastewater, which will not be described in detail in this embodiment.

[0050] See also Figure 2-Figure 4A treatment roller 4 for treating wastewater is fixedly arranged in the treatment cylinder 1; specifically, the outer wall of the treatment roller 4 is tightly fitted with the inner wall of the treatment cylinder 1, and the treatment roller 4 of this embodiment can be connected to the treatment cylinder 1 by bolts or pins.

[0051] Among them, a plurality of processing chambers 6 for storing multi-ion oxidizing gas catalysts are arranged in a circumferential array on the processing roller 4, and filter plates 601 are fixedly arranged at both ends of the processing chamber 6, and a plurality of filter holes 603 are evenly arranged on the filter plates 601; specifically, the present embodiment does not limit the number of processing chambers 6 to meet the actual needs of industrial wastewater treatment, wherein the multi-ion oxidizing gas can be ozone, hydrogen peroxide (H2O2) or chlorine dioxide (ClO2) and other strong oxidants, in the present embodiment, the multi-ion oxidizing gas is ozone gas.

[0052] It should be noted that the diameter of each filter hole 603 is smaller than the particle size of the multi-ion oxidizing gas catalyst particles, so that the multi-ion oxidizing gas catalyst cannot be discharged through the filter hole 603;

[0053] A gas input module is also provided in the treatment chamber 6 for conveying the multi-ion oxidizing gas into the treatment chamber 6; specifically, a preset amount of multi-ion oxidizing gas catalyst particles are stored in the treatment chamber 6. When the medical waste water is input into the treatment tube 1 via the waste water inlet pipe 102, the waste water first enters the treatment chamber 6 through the filter hole 603 of the filter plate 601 at the top of the treatment chamber 6. During this process, the multi-ion oxidizing gas is conveyed into the treatment chamber 6 through the gas input module. The multi-ion oxidizing gas catalyst interacts with the multi-ion oxidizing gas in the waste water to promote the oxidation efficiency of the hydroxyl radicals generated by the multi-ions, or forms a metal complex with the organic matter and enhances its redox ability, thereby accelerating the degradation of the organic matter in the waste water.

[0054] For further information, see Figure 3-Figure 4 , a plurality of groups of first sealing plates 401 corresponding to each top filter plate 601 are arranged in a circumferential array on the processing roller 4, and a plurality of groups of second sealing plates 5 corresponding to each bottom filter plate 601 are arranged in a circumferential array on the bottom of the processing roller 4;

[0055] The first sealing plate 401 and the second sealing plate 5 are connected to the lifting module that drives them to rise and fall; it can be explained that in the initial state, the first sealing plate 401 is correspondingly fitted with the filter plate 601 at the top of the processing chamber 6, and the second sealing plate 5 is correspondingly fitted with the filter plate 601 at the bottom of the processing chamber 6. At this time, the wastewater input into the processing cylinder 1 cannot enter the processing chamber 6. When the wastewater is treated, the first sealing plate 401 is first driven to rise and separate from the top filter plate 601 through the lifting module, and a water inlet gap is formed between the two, and the wastewater can pass through the gap and pass through the top filter plate The filter hole 603 of 601 enters the processing chamber 6. At this time, the second sealing plate 5 is still in a state of sealing the bottom filter plate 601. When the processing chamber 6 is full of wastewater, the first sealing plate 401 is driven by the lifting module to reset the seal. Then, the multi-ion oxidizing gas is delivered to the processing chamber 6 through the gas input module. After a period of reaction, the second sealing plate 5 is driven by the lifting module to descend and separate from the bottom filter plate 601, and a drainage gap is formed between the two. Wastewater can be discharged from the gap and through the filter hole 603 of the bottom filter plate 601 (see Figure 7 );

[0056] In the process of wastewater treatment in this embodiment, the wastewater to be treated can be temporarily stored in the treatment chamber 6 and treated, and external water cannot be input, thereby achieving an isolation effect. Therefore, by controlling the lifting state of the first sealing plate 401 and the second sealing plate 5 through the lifting module, the contact time between the wastewater and the multi-ion oxidizing gas and the multi-ion oxidizing gas catalyst can be adjusted, thereby further improving the wastewater treatment effect.

[0057] Example 2

[0058] Based on this Example 1, please refer to Figure 2 A detection box 101 connected to the treatment tube 1 is provided at the bottom, and a wastewater drainage pipe 103 is provided at the bottom of the detection box 101; specifically, after the wastewater is input into the treatment tube 1 through the wastewater inlet pipe 102, the wastewater is treated by the multi-ion oxidizing gas in the treatment chamber 6, and the treated wastewater can be discharged into the detection box 101, and finally discharged through the wastewater drainage pipe 103 for collection or further treatment.

[0059] Among them, the top of the processing roller 4 and the box wall of the processing cylinder 1 are enclosed to form an inlet chamber 106 connected to the wastewater inlet pipe 102, and the bottom of the processing roller 4 and the box wall of the processing cylinder 1 are enclosed to form a drainage chamber 107 connected to the detection box 101; specifically, after the wastewater enters the processing cylinder 1 through the wastewater inlet pipe 102, since the first sealing plate 401 and the filter plate 601 at the top of the processing chamber 6 are in a fitted and sealed state, the wastewater is first temporarily stored in the inlet chamber 106. When the first sealing plate 401 is separated from the filter plate 601, the wastewater can be discharged into the processing chamber 6, and the wastewater treated with the multi-ion oxidizing gas falls into the drainage chamber 107, and is finally discharged to the detection box 101 for detection.

[0060] For details, please refer to Figure 1 , a liquid level sensor and a water quality detector are also provided in the detection box 101, and a solenoid valve 104 is provided in the wastewater drainage pipe 103. The solenoid valve 104 is electrically connected to the liquid level sensor and the water quality detector through a controller, wherein a circulation pipe 105 is also provided on one side of the detection box 101, and the other end of the circulation pipe 105 is connected to the water inlet chamber 106, and a circulation pump 108 is provided in the circulation pipe 105; it can be explained that when the detected wastewater is discharged to the detection box 101, the water level in the detection box 101 is firstly detected by the liquid level sensor. When the detected water level reaches a preset value, the wastewater in the processing chamber 6 is stopped from entering the detection box 101. Secondly, the wastewater is tested for COD by the water quality detector. After the test is qualified, the solenoid valve 104 is opened to discharge the wastewater in the detection box 101 through the circulation pipe 105. If the test is unqualified, the circulation pump 108 is started to transport the wastewater to the water inlet chamber 106 again through the circulation pipe 105 to treat the wastewater again.

[0061] See also Figure 3-Figure 4 The lifting module includes a lifting rod 202 slidably arranged at the axial end of the processing tube 1, the first sealing plate 401 is connected to the lifting rod 202 through the first lifting part, and the second sealing plate 5 is connected to the lifting rod 202 through the second lifting part, wherein the driving mechanism 2 is fixedly arranged on the outside of the processing tube 1, and the driving end of the driving mechanism 2 is fixed to the lifting rod 202 through the lifting plate 201; it can be explained that, in this embodiment, when driving the first sealing plate 401 and the second sealing plate 5 to be lifted or lowered, the driving mechanism 2 first drives the lifting rod 202 to be lifted or lowered through the lifting plate 201, and during the lifting process, the lifting rod 202 drives the first sealing plate 401 to be lifted or lowered through the first lifting part, and drives the second sealing plate 5 to be lifted or lowered through the second lifting part.

[0062] In addition, the driving mechanism 2 in this embodiment can adopt a screw nut transmission device or a synchronous belt transmission device, which is not limited in this embodiment, and can be satisfied with driving the lifting plate 201 to rise and fall in the vertical direction.

[0063] In this embodiment, the first lifting part includes a first lifting ring 404 fixedly arranged on the lifting rod 202, each first sealing plate 401 is fixedly arranged with a first L-shaped bracket 402 on one side close to the lifting rod 202, each first L-shaped bracket 402 is fixedly arranged with a first convex plate 403 perpendicularly close to one side of the lifting rod 202, and the first lifting ring 404 is fitted with the first convex plate 403, wherein the first L-shaped bracket 402 is connected to the processing roller 4 through an elastic module; it can be explained that in the initial state, the first sealing plate 401 and the filter plate 601 are in a sealed fit. State, based on the setting of the elastic module, the first lifting ring 404 and the first convex plate 403 are also in a fitting state. When it is necessary to drive the first sealing plate 401 to separate from the filter plate 601, the lifting rod 202 is driven to rise through the driving mechanism. During the rising process, the lifting rod 202 can drive the first convex plate 403 to rise through the first lifting ring 404. The first convex plate 403 can drive the first sealing plate 401 to rise synchronously through the first L-shaped bracket 402. Correspondingly, when the first lifting ring 404 descends, the elastic module can drive the first sealing plate 401 to reset.

[0064] See also Figure 2 as well as Figure 4-Figure 5 as well as Figure 6 , the lifting rod 202 slides through the processing roller 4 and extends to the drainage chamber 107, the second lifting part includes a second lifting ring 505 fixedly arranged on the lifting rod 202, each second sealing plate 5 is fixedly arranged with a second L-shaped bracket 501 on one side of the lifting rod 202, each second L-shaped bracket 501 is fixedly arranged with a second convex plate 502 perpendicularly to one side of the lifting rod 202, the second lifting ring 505 is in contact with the second convex plate 502, wherein the second L-shaped bracket 501 is connected to the processing roller 4 through an elastic module; it can be explained that in the initial state, the second sealing plate 5 and the filter plate 601 is in a fitted and sealed state. Based on the setting of the elastic module, the second lifting ring 505 and the second convex plate 502 are also in a fitted and sealed state. When it is necessary to drive the second sealing plate 5 to separate from the filter plate 601, the lifting rod 202 is driven to descend through the driving mechanism. During the descent process, the lifting rod 202 can drive the second convex plate 502 to descend through the second lifting ring 505. The second convex plate 502 can drive the second sealing plate 5 to descend synchronously through the second L-shaped bracket 501. Accordingly, when the second lifting ring 505 rises, the elastic module can drive the second sealing plate 5 to reset.

[0065] As a further solution of this embodiment, the elastic module includes a guide rod 503 slidably arranged in the first L-shaped bracket 402 and the second L-shaped bracket 501, each guide rod 503 is fixed on the processing roller 4, wherein a reset spring 504 is provided on the guide rod 503; specifically, one end of the reset spring 504 is fixed to the L-shaped bracket, and the other end is fixed to the end of the guide rod 503; it can be explained that when the first lifting ring 404 drives the first L-shaped bracket 402 to move, the first L-shaped bracket 402 moves synchronously on the guide rod 503, and the first L-shaped bracket 402 can drive the reset spring 504 to produce an elastic force change, and when the second lifting ring 505 drives the second L-shaped bracket 501 to move, the second lifting ring 505 moves synchronously on the guide rod 503, and the second L-shaped bracket 501 can also drive the reset spring 504 to produce an elastic force change, and then the first L-shaped bracket 402 and the second L-shaped bracket 501 can be synchronously driven to reset by the reset spring 504.

[0066] See also Figure 2 The gas input module includes a through hole 303 opened at the center end of the second sealing plate 5, and one end of the through hole 303 facing the drainage chamber 107 is connected to the air intake branch pipe 301, wherein an air intake main pipe 3 is provided in the detection box 101, and each air intake branch pipe 301 is connected to the air intake main pipe 3, and the other end of the air intake main pipe 3 is connected to the output end of the multi-ion oxidizing gas source; specifically, when the multi-ion oxidizing gas is input into the processing chamber 6, the multi-ion oxidizing gas is first transported to the air intake main pipe 3 through the multi-ion oxidizing gas source, and then transported to the processing chamber 6 through the air intake branch pipe 301.

[0067] For further information, see Figure 2 and Figure 5, in order to prevent part of the multi-ion oxidizing gas from still being input into the processing chamber 6 when the first sealing plate 401 and the second sealing plate 5 are separated from the filter plate 601, in this embodiment, a first air pipe 604 connected to the through hole 303 is fixedly arranged on one end of the second sealing plate 5 facing the processing chamber 6, and a plurality of groups of first air holes 605 arranged at intervals are evenly arranged on the first air pipe 604, and the first air holes 605 are connected to the air nozzles 606 arranged on the pipe wall, and a second air pipe 602 is fixedly arranged on one end of the first sealing plate 401 facing the processing chamber 6, and the pipe wall of the second air pipe 602 is slidably fitted with the pipe wall of the first air pipe 604, wherein a plurality of groups of second air holes 607 arranged at intervals are evenly arranged on the second air pipe 602; specifically, when the first sealing plate 401 and the second sealing plate 5 are both fitted and sealed with the filter plate 601, the first air holes 605 and the second air holes 607 are in a connected state, and the multi-ion oxidizing gas in the air inlet branch pipe 301 can be input into the first through hole 303 In the air pipe 604, it is finally discharged into the processing chamber 6 through the second air hole 607 and the air nozzle 606. When the first sealing plate 401 or the second sealing plate 5 moves in the direction away from the filter plate 601, the first air hole 605 and the second air hole 607 will be in a staggered sealing state, so the multi-ion oxidizing gas entering the first air pipe 604 will not be discharged into the processing chamber 6. Therefore, the multi-ion oxidizing gas is only input when the first sealing plate 401 and the second sealing plate 5 are both in a sealed state to the filter plate 601. On the one hand, the waste of multi-ion oxidizing gas can be avoided. On the other hand, when the multi-ion oxidizing gas is input, since the filter plates 601 on both sides are sealed, the pressure in the processing chamber 6 will increase with the input of the multi-ion oxidizing gas. According to Henry's law, the solubility of the multi-ion oxidizing gas will increase with the increase of pressure. The increase of solubility helps to improve the mass transfer rate and utilization efficiency of the multi-ion oxidizing gas, thereby improving the wastewater treatment efficiency.

[0068] Furthermore, a telescopic tube 302 is further provided in the air intake branch pipe 301 to avoid motion interference caused when the second sealing plate 5 is raised or lowered.

[0071] See also Figure 2-Figure 4 , S2, the lifting module drives the first sealing plate 401 to rise and separate from the top filter plate 601, forming a water inlet gap between the two, and the wastewater can enter the processing chamber 6 through the gap and the filter hole 603 of the top filter plate 601. At this time, the second sealing plate 5 is still in a state of sealing the bottom filter plate 601;

[0072] S3, when the treatment chamber 6 is filled with wastewater, the lifting module drives the first sealing plate 401 to reset and seal;

[0073] S4, delivering multi-ion oxidizing gas into the processing chamber 6 through the gas input module;

[0074] S5. After a period of reaction, the second sealing plate 5 is driven down by the lifting module and separated from the bottom filter plate 601 , forming a drainage gap between the two. Wastewater can be discharged from the gap and through the filter holes 603 of the bottom filter plate 601 .
