Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment equipment technology, and more specifically, to an industrial high-concentration organic wastewater treatment equipment. Background Technology

[0002] In many industrial sectors, such as chemical, pharmaceutical, and printing and dyeing production processes, a large amount of high-concentration organic wastewater is generated. This wastewater has an extremely high concentration of organic matter and a complex and diverse composition, including various aromatic hydrocarbons, halogenated hydrocarbons, heterocyclic compounds, and other recalcitrant organic pollutants. Due to the high concentration of organic matter, traditional wastewater treatment technologies face many challenges.

[0003] A search revealed that Chinese patent CN218231888U discloses an industrial organic wastewater treatment device. Addressing the issue in its application documents that the usage of the liquid in the reagent tank was not readily observable by the user, this patent employs a warning mechanism that displays the liquid level in the tank in real time. Users can determine the liquid level by observing the exposed length of the connecting rod, allowing for more timely replenishment. Furthermore, this fully automated mechanism offers greater convenience.

[0004] In the treatment of some high-concentration organic wastewater, the high concentration of organic matter has a toxic and inhibitory effect on microorganisms, which can seriously affect the activity and metabolic function of microorganisms. This makes it difficult for microorganisms to effectively decompose the organic matter in the wastewater, resulting in a significant reduction in treatment effectiveness. In some wastewater treatment equipment that uses ozone, the lack of efficient mixing and dispersion devices in the ozone treatment stage prevents ozone from fully contacting the high-concentration organic wastewater. As a result, a large amount of ozone is discharged without participating in the reaction, leading to resource waste and low treatment efficiency. Utility Model Content

[0005] In order to overcome the problems and defects in the prior art, this utility model provides an industrial high-concentration organic wastewater treatment device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an industrial high-concentration organic wastewater treatment device, including a device platform, wherein an ozone treatment mechanism is provided on the top of the device platform;

[0007] The ozone treatment mechanism includes an ozone generator, which is fixedly installed on the top of the equipment platform. An air pump is fixedly installed on the top of the ozone generator. A sewage treatment tank is provided on one side of the ozone generator. A connecting air pipe is fixedly connected to the top of the air pump. A fixing box is provided at the bottom of the connecting air pipe. The fixing box is fixed to the top of the sewage treatment tank. A sewage inlet pipe is fixedly connected to the top of the sewage treatment tank.

[0008] A rotating tube is provided at the bottom of the connecting air pipe, and a rotating joint is installed between the connecting air pipe and the rotating tube. A first gear is fixedly sleeved on the outside of the rotating tube. A motor is fixedly installed on the top of the inner wall of the fixed box. A second gear is fixedly connected to the output end of the motor. Fixed tubes are fixedly connected to both sides of the rotating tube. Multiple exhaust check valves are fixedly installed on the outside of the fixed tubes.

[0009] Preferably, one end of the connecting air pipe passes through the bottom of the fixing box and extends into the interior of the fixing box, the rotating pipe passes through the sewage treatment tank and extends into the interior of the sewage treatment tank, and the rotating pipe is rotatably connected to the sewage treatment tank.

[0010] Preferably, the first gear and the second gear mesh with each other.

[0011] Preferably, a treatment box is fixedly installed on the top of the equipment platform near the side of the sewage treatment tank, and a connecting pipe is fixedly connected between the sewage treatment tank and the treatment box.

[0012] Preferably, a water pump is fixedly installed at the bottom of the connecting pipe, and multiple isolation plates are fixedly connected to both sides of the inner wall of the treatment tank.

[0013] Preferably, the top and bottom surfaces of the isolation plate are provided with fixing grooves, and ultraviolet lamps are fixedly installed inside the fixing grooves.

[0014] Preferably, a drain pipe is fixedly connected to one side of the processing box.

[0015] Preferably, a support column is fixedly connected between the sewage treatment tank and the equipment platform.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] 1. By setting up an ozone treatment mechanism, ozone gas can fully and evenly contact the sewage entering from the sewage inlet pipe, increasing the contact area and effect between ozone and sewage, creating better conditions for ozone to degrade organic pollutants in sewage. The rotation of the rotating pipe plays a stirring and mixing role. Inside the sewage treatment tank, the rotating pipe drives the fixed pipe to rotate, stirring the sewage and ozone gas in the tank, breaking the mass transfer resistance between sewage and ozone gas, accelerating the diffusion of ozone into the sewage, making ozone disperse more quickly and evenly in the sewage, allowing ozone to fully react with organic pollutants in the sewage, improving the efficiency of ozone oxidation and degradation of organic pollutants, and enhancing the sewage treatment effect.

[0018] 2. By slowing down the flow of sewage through multiple layers of partitions inside the treatment tank, the sewage's residence time is extended, allowing it more time to come into contact with the ultraviolet lamps installed at the top and bottom of the partitions. The ultraviolet lamps perform photocatalytic oxidation treatment, which can further degrade recalcitrant organic matter. Combined with the previous ozone oxidation treatment, this significantly improves the purification level of the sewage, making it easier for the treated sewage to meet discharge standards or enter the next treatment stage.

The fixing box 6 is fixed to the top of the sewage treatment tank 4. A sewage inlet pipe 7 is fixedly connected to the top of the sewage treatment tank 4.

[0029] A rotating tube 9 is provided at the bottom of the connecting air pipe 5. A rotating joint 8 is installed between the connecting air pipe 5 and the rotating tube 9. A first gear 10 is fixedly sleeved on the outside of the rotating tube 9. A motor 11 is fixedly installed on the top of the inner wall of the fixed box 6. A second gear 12 is fixedly connected to the output end of the motor 11. Fixed tubes 13 are fixedly connected to both sides of the rotating tube 9. Multiple exhaust check valves 14 are fixedly installed on the outside of the fixed tubes 13.

[0030] As attached Figure 4 , 6 As shown, one end of the connecting tube 5 passes through the bottom of the fixed box 6 and extends into the interior of the fixed box 6. The rotating tube 9 passes through the sewage treatment tank 4 and extends into the interior of the sewage treatment tank 4. The rotating tube 9 is rotatably connected to the sewage treatment tank 4. The first gear 10 and the second gear 12 mesh with each other, so that the rotating tube 9 can rotate. At the same time, the rotating joint 8 remains fixed, so that the rotating tube 9 can improve the contact effect between ozone and sewage during rotation.

[0031] As attached Figure 1-5 As shown, a treatment box 16 is fixedly installed on the top of the equipment platform 1 near the sewage treatment tank 4. A connecting pipe 15 is fixedly connected between the sewage treatment tank 4 and the treatment box 16. A water pump 17 is fixedly installed at the bottom of the connecting pipe 15. Multiple isolation plates 18 are fixedly connected to both sides of the inner wall of the treatment box 16. Fixed grooves 19 are opened on the top and bottom surfaces of the isolation plates 18. Ultraviolet lamps 20 are fixedly installed inside the fixed grooves 19. The multiple isolation plates 18 slow down the sewage flow rate, so that it is continuously irradiated by the ultraviolet lamps 20 to produce a photocatalytic reaction.

[0032] As attached Figure 1 , 3 As shown in Figure 4, a drain pipe 21 is fixedly connected to one side of the treatment box 16 to facilitate the discharge of sewage through the drain pipe 21.

[0033] As attached Figure 1-4 As shown, a support column 22 is fixedly connected between the sewage treatment tank 4 and the equipment platform 1, making the sewage treatment tank 4 more stable.

[0034] The working principle of this utility model is as follows: The ozone generator 2 is started on the top of the equipment platform 1 to generate ozone gas. The gas pump 3 delivers the ozone gas to the fixed box 6 through the connecting gas pipe 5. The connecting gas pipe 5 is connected to the rotating pipe 9 through the rotary joint 8. The rotating pipe 9 rotates under the drive of the motor 11. The second gear 12 at the output end of the motor 11 meshes with the first gear 10 on the rotating pipe 9, driving the rotating pipe 9 to rotate. The fixed pipes 13 on both sides of the rotating pipe 9 distribute the ozone gas evenly into the sewage treatment tank 4. Multiple exhaust check valves 14 installed on the fixed pipes 13 ensure that the ozone gas is discharged smoothly and at the same time prevent sewage backflow. The sewage enters the sewage treatment tank 4 through the sewage inlet pipe 7 and comes into full contact with the ozone gas. The strong oxidizing properties of ozone degrade the organic pollutants in the sewage.

[0035] Wastewater treated with ozone enters treatment tank 16 through connecting pipe 15. Water pump 17 pumps wastewater from wastewater treatment tank 4 into treatment tank 16. Treatment tank 16 is equipped with multiple layers of isolation plates 18, which are fixedly installed through fixing grooves 19. The design of isolation plates 18 slows down the flow rate of wastewater and prolongs the residence time of wastewater in treatment tank 16, ensuring the subsequent treatment effect. Ultraviolet lamps 20 installed at the top and bottom of isolation plates 18 perform photocatalytic oxidation treatment on wastewater, further degrading recalcitrant organic matter.

[0036] Wastewater treated by ozone oxidation and photocatalytic oxidation is finally purified in treatment tank 16. The purified water is discharged from the equipment through drain pipe 21 and enters the next treatment stage or is discharged in compliance with standards. Wastewater treatment tank 4 is fixed on equipment platform 1 by support column 22 to ensure the stability and safety of equipment operation.
