Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, and in particular to an ultraviolet-ozone integrated wastewater treatment device. Background Art

[0002] Many industrial wastewaters contain difficult-to-degrade organic pollutants. It is costly to use physical and chemical methods for advanced oxidation alone. Therefore, the difficult-to-degrade organic pollutants are first oxidized and broken, and the large molecules that cannot be biochemically degraded are degraded into small molecules that can be biochemically degraded. The organic pollutants are further degraded and removed through biochemical treatment, and nitrogen and phosphorus are removed at the same time. This not only reduces a lot of operating costs, but also simplifies the operation. Through advanced oxidation (ultraviolet + ozone), large molecules of difficult-to-degrade organic matter are degraded into small molecules of biodegradable and easily degradable organic matter, providing a guarantee for subsequent biochemical treatment.

[0003] After the staff discharges the wastewater into the wastewater treatment tank, the flocs are recycled during the wastewater degradation process. After the wastewater is oxidatively degraded in the device, it passes through the holes in the outer partition and enters the separation zone at the innermost layer. The water flows upward through the outlet weir and the suspended matter in the water enters the bottom wall of the wastewater treatment tank along the inclined wall of the tank. The staff needs to regularly clean the sediment on the bottom wall of the wastewater treatment tank. When cleaning the sediment on the bottom wall, the staff needs to discharge the water inside the wastewater treatment tank, and cannot automatically clean the sediment on the bottom wall, which not only increases the labor intensity of the staff, but also reduces the wastewater treatment speed. Summary of the invention

[0004] The purpose of the present invention is to solve at least one of the technical problems existing in the prior art and to provide an integrated ultraviolet ozone wastewater treatment device that can solve the problem that staff need to regularly clean the bottom wall sediment of the wastewater treatment pool. When cleaning the bottom wall sediment, the staff need to discharge the water inside the wastewater treatment pool, and cannot automatically clean the bottom wall sediment, which not only increases the labor intensity of the staff, but also reduces the wastewater treatment speed.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an ultraviolet ozone integrated wastewater treatment device, comprising a wastewater treatment tank and a sediment cleaning device; two inclined surfaces are provided at the bottom of the wastewater treatment tank; the sediment cleaning device comprises two sliding bars, eight cleaning plates, a movable plate, a driving motor, a rotating rod and a rotating shaft, the two sliding bars are both slidably connected to the inside of the wastewater treatment tank, the eight cleaning plates are respectively fixedly connected to the surfaces of the two sliding bars, the bottoms of the cleaning plates are in contact with the inclined surfaces, the two sliding bars extend to the outside of the wastewater treatment tank, the movable plate is fixedly connected to the right ends of the two sliding bars, the driving motor is fixedly installed on the right side of the wastewater treatment tank, and the rotating rod is fixedly connected to the output end of the driving motor.

[0006] Preferably, a water distribution pipe is fixedly connected to the interior of the wastewater treatment tank, and the upper end of the water distribution pipe extends to the outside of the wastewater treatment tank.

[0009] Preferably, an ozone generator is arranged at the rear side of the wastewater pool, an exhaust pipe is fixedly connected to the surface of the ozone generator, and the front end of the exhaust pipe is fixedly connected to the surface of the input pipe.

[0010] Preferably, two ultraviolet devices are fixedly installed inside the wastewater treatment tank, and a drain pipe is fixedly connected to the left end of the wastewater treatment tank.

[0013] Preferably, a sealing cover plate is slidably mounted on the left end of the wastewater treatment tank.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The UV-ozone integrated wastewater treatment device no longer requires staff to manually clean the sediment on the bottom wall of the wastewater treatment pool, and there is no need to discharge the water inside the wastewater treatment pool. The wastewater treatment pool can continuously treat the wastewater. The sediment can be automatically cleaned to the outside of the wastewater treatment pool through the cleaning plate and the auger, which not only reduces the labor intensity of the staff, but also improves the wastewater treatment speed.

[0016] 2. The UV-ozone integrated wastewater treatment device does not add any additional chemicals, which will complicate the types of pollutants in the wastewater. It can not only be used before biochemical treatment to degrade large molecular refractory organic matter into small molecular biodegradable and easily degradable organic matter, thus providing biodegradability to the wastewater.

The two slide bars can drive the cleaning plate to slide left and right to clean the sediment on the inclined surface. Since the two inclined surfaces are inclined structures, the sediment can automatically slide downward by its own gravity. The staff no longer needs to manually clean the sediment, which improves the convenience of sediment cleaning. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] See also Figure 1-6 The present invention provides a technical solution: an ultraviolet ozone integrated wastewater treatment device, comprising a wastewater treatment pool 1 and a sediment cleaning device, wherein a water distribution pipe 2 is fixedly connected to the interior of the wastewater treatment pool 1, and the upper end of the water distribution pipe 2 extends to the outside of the wastewater treatment pool 1, a gas-liquid mixing pump 3 is arranged at the right end of the wastewater treatment pool 1, a discharge pipe 4 is fixedly connected to the output end of the gas-liquid mixing pump 3, and the left end of the discharge pipe 4 is fixedly connected to the upper end of the water distribution pipe 2, an input pipe 5 is fixedly connected to the input end of the gas-liquid mixing pump 3, a wastewater pool 6 is arranged on the right side of the gas-liquid mixing pump 3, and the right end of the input pipe 5 extends to the interior of the wastewater pool 6, an ozone generator 7 is arranged on the rear side of the wastewater pool 6, an exhaust pipe 8 is fixedly connected to the surface of the ozone generator 7, and the front end of the exhaust pipe 8 is fixedly connected to the surface of the input pipe 5, two ultraviolet devices 9 are fixedly installed inside the wastewater treatment pool 1, a drain pipe 10 is fixedly connected to the left end of the wastewater treatment pool 1, and two inclined surfaces 11 are provided at the bottom of the wastewater treatment pool 1.

[0031] When the ultraviolet ozone integrated wastewater treatment device is in use, after the staff starts the gas-liquid mixing pump 3, the wastewater stored in the wastewater pool 6 can be extracted through the input pipe 5. At the same time, the ozone in the ozone generator 7 is extracted through the exhaust pipe 8 and discharged into the water distribution pipe 2, and evenly discharged into the wastewater treatment pool 1 through the water distribution pipe 2. At this time, the water flows to the ultraviolet zone between the two ultraviolet devices 9. The poor transparency of the wastewater will affect the penetration ability of ultraviolet radiation. The internal circulation method is adopted to allow the water body to flow, increase the contact between the wastewater and the ultraviolet, and improve the ultraviolet treatment effect. The production of flocs is reused in the wastewater degradation process. After the wastewater is oxidatively degraded in the device, it enters the separation zone of the outer layer through the holes of the outer partition. The water body is discharged from the position of the drain pipe 10, and the suspended matter in the water body falls along the inclined wall of the pool body to the surface of the two inclined surfaces 11.

[0032] The oxidation method of the UV-ozone integrated wastewater treatment device does not add any additional agents, which will complicate the types of pollutants in the wastewater. It can not only be used before biochemical treatment to degrade large molecular refractory organic matter into small molecular biodegradable and easily degradable organic matter, thus providing biodegradability to the wastewater. It can also be used for deep treatment at the end of biochemical treatment of sewage to remove organic pollutants and chromaticity in the wastewater. At the same time, ozone also has a disinfecting effect, and the wastewater treated by the device does not need to be disinfected separately.

[0033] The sediment cleaning device includes two slide bars 12, eight cleaning plates 13, a movable plate 14, a driving motor 15, a rotating rod 16 and a rotating shaft 17. The two slide bars 12 are both slidably connected to the inside of the wastewater treatment tank 1. The eight cleaning plates 13 are respectively fixedly connected to the surfaces of the two slide bars 12. The bottoms of the cleaning plates 13 are in contact with the inclined surfaces 11. The two slide bars 12 extend to the outside of the wastewater treatment tank 1. The movable plate 14 is fixedly connected to the right ends of the two slide bars 12. The driving motor 15 is fixedly installed on the right side of the wastewater treatment tank 1. The rotating rod 16 is fixedly connected to the output end of the driving motor 15. The rotating shaft 17 is fixedly connected to one end of the rotating rod 16. The surface of the rotating shaft 17 is slidably connected to the inside of the mobile plate 14.

[0034] When the amount of sediment on the surfaces of the two inclined surfaces 11 increases, the driving motor 15 can be started. The rotation of the output end of the driving motor 15 can drive the rotating rod 16 to rotate. The rotation of the rotating rod 16 can drive the rotating shaft 17 to rotate in a circle and squeeze the inner wall of the movable plate 14, thereby driving the movable plate 14 to slide left and right. The left and right sliding of the movable plate 14 can drive the two sliding rods 12 to slide left and right. The left and right sliding of the two sliding rods 12 can drive the cleaning plate 13 to slide left and right to clean the sediment on the surface of the inclined surfaces 11. Since the two inclined surfaces 11 are inclined structures, the sediment can automatically slide down to the lower side by its own gravity. The staff no longer needs to manually clean the sediment, which improves the convenience of cleaning the sediment.

[0035] A sludge storage groove 18 is provided on the bottom wall of the wastewater treatment tank 1 , an auger 19 is installed inside the sludge storage groove 18 , and a sealing cover plate 20 is slidably installed on the left end of the wastewater treatment tank 1 .

[0036] The sediment automatically slides downward to the inside of the sludge storage groove 18. After the staff starts the transmission device, the auger 19 can be driven to rotate. After the staff removes the sealing cover 20, the rotation of the auger 19 can drive the sediment to gradually move to the left, and the sediment is gradually moved out of the wastewater treatment tank 1. The staff no longer needs to manually clean the sediment on the bottom wall of the wastewater treatment tank 1, and there is no need to drain the water inside the wastewater treatment tank 1. The wastewater treatment tank 1 can continue to treat the wastewater. The sediment can be automatically cleaned to the outside of the wastewater treatment tank 1 through the cleaning plate 13 and the auger 19, which not only reduces the labor intensity of the staff, but also improves the wastewater treatment speed.

[0037] Working principle: After the staff starts the gas-liquid mixing pump 3, the wastewater stored in the wastewater pool 6 can be extracted through the input pipe 5. At the same time, the ozone in the ozone generator 7 is extracted through the exhaust pipe 8 and discharged into the water distribution pipe 2, and then evenly discharged into the wastewater treatment pool 1 through the water distribution pipe 2. At this time, the water flows to the ultraviolet zone between the two ultraviolet devices 9. The poor transparency of the wastewater will affect the penetration ability of ultraviolet radiation. The internal circulation method is adopted to allow the water body to flow, increase the contact between the wastewater and the ultraviolet, and improve the ultraviolet treatment effect. The production of floccules is reused in the wastewater degradation process. After the wastewater is oxidized and degraded in the device, it enters the separation zone of the outer layer through the holes of the outer partition. The water body is discharged from the position of the drain pipe 10, and the suspended matter in the water body falls along the inclined wall of the pool body to the surface of the two inclined surfaces 11. The work can start the drive motor 15 The output end of the driving motor 15 rotates to drive the rotating rod 16 to rotate. The rotation of the rotating rod 16 can drive the rotating shaft 17 to rotate in a circle and squeeze the inner wall of the movable plate 14, thereby driving the movable plate 14 to slide left and right. The movable plate 14 slides left and right to drive the two slide bars 12 to slide left and right. The two slide bars 12 slide left and right to drive the cleaning plate 13 to slide left and right to clean the sediment on the surface of the inclined surface 11. The sediment automatically slides downward to the inside of the sludge storage groove 18. After the staff starts the transmission device, the auger 19 can be driven to rotate. After the staff removes the sealing cover plate 20, the rotation of the auger 19 can drive the sediment to gradually move to the left, and the sediment is gradually moved out of the wastewater treatment tank 1. The staff no longer needs to manually clean the sediment on the bottom wall of the wastewater treatment tank 1, which not only reduces the labor intensity of the staff, but also improves the wastewater treatment speed.

[0038] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
