Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an ozone catalytic oxidation tank. Background Technology

[0002] Ozone catalytic oxidation tanks are typically constructed with reinforced concrete or steel to ensure excellent sealing. This is because ozone is a toxic gas, and preventing leakage is crucial. The tank shape can be designed as rectangular, circular, etc., depending on the treatment scale and site conditions. Rectangular tanks are more convenient in terms of space utilization, while circular tanks may have advantages in terms of hydraulic conditions, enabling good circulation of wastewater within the tank, which is beneficial for the reaction.

[0003] Existing wastewater treatment facilities are relatively simple, mainly relying on process-based treatment. Especially in the process after ozone treatment, there are fewer treatment steps, and a centralized treatment method is adopted. As a result, the reaction time between processes is short, the capacity is large, and the reaction efficiency is low, resulting in poor water treatment effect. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model proposes an ozone catalytic oxidation tank.

[0005] The technical solution of this utility model is implemented as follows: an ozone catalytic oxidation tank, comprising:

[0006] The raw water channel, which is equipped with a grid, is connected to the first reaction tank.

[0007] An ozone reaction zone is provided, and a filtration system is provided on one side of the ozone reaction zone. The filtration system is used to draw the wastewater treated in the first reaction tank into the ozone reaction zone. A water collection tank is provided on one side of the first reaction tank. The water collection tank is used to isolate impurities in the water in the first reaction tank.

[0008] A cleaning tank is connected to the ozone reaction zone via a water supply pipe, and a sealing cover is provided on the top of the ozone reaction zone.

[0009] The mixing tank is equipped with a stirring device, and the bottom of the mixing tank is set as a bucket-shaped area. The upper part of the inner wall of the mixing tank forms a reflux pool, and the tail end of the reflux pool is provided with a flow collection channel.

[0010] The water purification section is connected to the treatment system. The water purification section includes a first settling tank and a second settling tank located in the middle, as well as a first treatment tank and a second treatment tank located outside the first settling tank and the second settling tank.

[0011] Furthermore, the first reaction tank is equipped with an external discharge port connected to an external sewage pump, and an aeration pipe is installed inside the first reaction tank.

[0012] Furthermore, the stirring device includes a drive motor, which is fixedly connected to the stirring tank via a grid. The drive motor is equipped with a drive rod, and the drive rod is equipped with two winding wheels. Two stirring rods are movably connected to the bottom end of the drive rod, and the winding wheels are fixedly connected to the two stirring rods via pull ropes.

[0013] Furthermore, a water pump is installed at the bottom of the flow channel, and the water pump is connected to the diversion pipe. The diversion ends of the diversion pipe are located on the first treatment tank and the second treatment tank, respectively.

[0014] Furthermore, a collection area is provided on one side of the first settling tank and the second settling tank. The collection area is equipped with a conveying pipe, which conveys the water in the collection area to a water purification tank. The water purification tank is located on one side of the mixing tank. A conveying pipe is provided in the first settling tank and the second settling tank, and the conveying pipe conveys the water to the collection area.

[0015] Furthermore, the first treatment tank and the second treatment tank are used to receive water from the flow channel. The water from the first treatment tank and the second treatment tank flows into the first settling tank and the second settling tank. A reaction pipe is provided in the first treatment tank and the second treatment tank. The reaction pipe is connected to the aeration component in the treatment system. A detonation device is provided on the reaction pipe.

[0016] This utility model has the following beneficial effects:

[0017] 1. By setting up a cleaning tank and installing a sealed cover on top of the ozone reaction zone, the ozone reaction zone is connected to the ozone generator in the treatment system via an ozone delivery pipe. Ozone then reacts with the treated water to treat the ozone. Ozone generation typically utilizes high-voltage discharge or electrolysis to convert oxygen or pure oxygen from the air into ozone. The generated ozone is then evenly distributed into the oxidation tank through a gas distribution system.

[0018] 2. The sealed cover isolates the treated exhaust gas within the ozone reaction zone. A gas suction pipe is installed between the cleaning tank and the ozone reaction zone, allowing the exhaust gas to be drawn into the cleaning tank. Unreacted ozone will escape from the wastewater surface, forming exhaust gas. This exhaust gas contains a certain amount of ozone; if directly released into the atmosphere, it will harm the environment and human health. The exhaust gas is collected through the gas suction pipe and then enters the cleaning tank.

[0019] 3. The aeration pipes are connected to the aeration devices on the treatment system. After the raw water from the original water channel passes through the grid, it enters the first reaction tank. The aeration pipes connected to the aeration devices then transmit gas to the first reaction tank, providing oxygen needed by the microorganisms to decompose organic pollutants in the wastewater. The aeration devices deliver oxygen from the air to the wastewater, enabling the microorganisms to perform aerobic respiration. Attached Figure Description

[0024] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Reference Figures 1 to 3 An ozone catalytic oxidation tank, as shown, includes:

[0026] Raw water channel 1, wherein a grid 2 is installed within raw water channel 1, and raw water channel 1 is connected to the first reaction tank 4.

[0027] Ozone reaction zone 5, with a filtration system 24 on one side of the ozone reaction zone 5, the filtration system 24 is used to draw the treated wastewater in the first reaction tank 4 into the ozone reaction zone 5, wherein a water collection tank 6 is provided on one side of the first reaction tank 4, the water collection tank 6 is used to isolate impurities in the water in the first reaction tank 4;

[0028] The cleaning tank 3 is connected to the ozone reaction zone 5 via a water supply pipe, and the top of the ozone reaction zone 5 is equipped with a sealing cover.

[0029] By configuring the cleaning tank 3 and sealing the top of the ozone reaction zone 5 with a cap, the ozone reaction zone 5 is connected to the ozone generator at the treatment system 21 via an ozone delivery pipe. Ozone then interacts with the water treated by the filtration system 24. Ozone generation typically utilizes high-voltage discharge or electrolysis to convert oxygen or pure oxygen from the air into ozone. The generated ozone is evenly distributed into the oxidation tank via an aeration system. This aeration system can be devices such as microporous aeration discs or jet injectors. The microporous aeration discs release ozone into the water in the form of tiny bubbles, increasing the contact area between ozone and wastewater and improving ozone mass transfer efficiency. The jet injector uses the negative pressure generated by the high-speed water flow to draw in ozone and mix it with water, ensuring even dispersion. Both methods are acceptable. The sealed cover isolates the treated exhaust gas within the ozone reaction zone 5. A gas suction pipe is installed between the cleaning tank 3 and the ozone reaction zone 5, allowing the exhaust gas to be drawn into the cleaning tank 3. Unreacted ozone will escape from the wastewater surface, forming exhaust gas. This exhaust gas contains a certain amount of ozone; direct release into the atmosphere would harm the environment and human health. The exhaust gas is collected through the gas suction pipe and enters the cleaning tank 3. Various exhaust gas treatment methods exist, such as activated carbon adsorption, which uses the adsorption properties of activated carbon to adsorb ozone onto its surface, thus removing ozone from the exhaust gas; thermal decomposition, which heats the exhaust gas to a certain temperature, decomposing ozone into oxygen; and chemical absorption, which uses chemical agents such as potassium iodide solution to react with ozone, absorbing and removing it. The cleaning tank 3 can utilize one or more of these exhaust gas treatment methods.

[0030] A stirring device 8 is provided inside the stirring tank 7, and the bottom of the stirring tank 7 is set as a bucket-shaped area 9. A reflux pool 10 is formed above the inner wall of the stirring tank 7, and a flow collection channel 14 is provided at the tail end of the reflux pool 10.

[0031] After the water in the ozone reaction zone 5 enters the mixing tank 7, it is stirred by the stirring device 8, which helps to evenly distribute the internal nutrients, prevents the aggregation of microorganisms, and ensures the even distribution of chemical drugs. In this way, the water at the bottom of the tank surges to the surface, and the water at the top can flow into the return tank 10, and then the treated water can flow out in the collection channel 14.

[0032] The water purification section is connected to the treatment system 21. The water purification section includes a first settling tank 17 and a second settling tank 18 located in the middle, and a first treatment tank 16 and a second treatment tank 19 located outside the first settling tank 17 and the second settling tank 18.

[0033] The first reaction tank 4 is provided with an external discharge port 12 connected to an external sewage suction pump, and the first reaction tank 4 is provided with an aeration pipe 13.

[0034] Aeration pipe 13 is connected to the aeration device on the treatment system 21. Thus, after the raw water in the raw water channel 1 passes through the grid 2 and enters the first reaction tank 4, the aeration pipe 13, connected to the aeration device, transmits gas to the first reaction tank 4, supplying oxygen needed by microorganisms to decompose organic pollutants in the wastewater. The aeration device delivers oxygen from the air to the wastewater, enabling the microorganisms to perform aerobic respiration.

[0035] The stirring device 8 includes a drive motor 81, which is fixedly connected to the stirring tank 7 via a grid 2. The drive motor 81 is provided with a drive rod 83, and the drive rod 83 is provided with two winding wheels 86. The bottom end of the drive rod 83 is movably connected to two stirring rods 85. The winding wheels 86 are fixedly connected to the two stirring rods 85 via a pull rope 84.

[0036] During use, the drive motor 81 can drive the drive rod 83 to rotate, so that the water inside is continuously mixed in the bucket-shaped area 9. During use, the angle of the stirring rod 85 can be adjusted. When the winding wheel 86 is rotated and the winding wheel 86 retracts the pull rope 84, the stirring rod 85 rotates on the drive rod 83, so the angle of the stirring rod 85 can be adjusted.

[0037] A water pump is installed at the bottom of the flow channel 14. The water pump is connected to the diversion pipe 15. The diversion ends of the diversion pipe 15 are located on the first treatment tank 16 and the second treatment tank 19, respectively.

[0038] A collection area is provided on one side of the first settling tank 17 and the second settling tank 18. The collection area is provided with a conveying pipe, which conveys the water in the collection area to a water purification tank. The water purification tank is located on one side of the stirring tank 7. A conveying pipe 23 is provided in the first settling tank 17 and the second settling tank 18, which conveys the water to the collection area.

[0039] The first treatment tank 16 and the second treatment tank 19 are used to receive water from the flow channel 14. The water from the first treatment tank 16 and the second treatment tank 19 flows into the first settling tank 17 and the second settling tank 18. A reaction pipe 22 is provided in the first treatment tank 16 and the second treatment tank 19. The reaction pipe 22 is connected to the aeration component in the treatment system 21. A detonation device 20 is provided on the reaction pipe 22.

[0040] By installing a detonation device 20 on the reaction tube 22, which can be an ultrasonic generator, smaller bubbles can be generated. Under the action of the detonation device 20, the bubbles are more evenly distributed in the water, thereby improving the water treatment effect.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
