Abstract
Description
Technical Field
[0001] This utility model relates to the field of domestic sewage treatment technology, specifically to a deodorization and purification device for domestic sewage treatment. Background Technology
[0002] With the acceleration of urbanization and the improvement of residents' living standards, the discharge of domestic sewage has been increasing year by year, and the number of sewage treatment-related facilities such as sewage treatment plants, sewage lifting pump stations, and septic tanks has also increased accordingly. During the operation of these facilities, due to the decomposition of organic matter such as proteins, fats, and carbohydrates contained in the sewage by anaerobic microorganisms, malodorous gases, mainly hydrogen sulfide, ammonia, and volatile organic compounds, are produced.
[0003] Currently, existing domestic sewage treatment and deodorization technologies have significant shortcomings. The core problem lies in the fact that they generally rely solely on activated carbon adsorption for deodorization, resulting in an extremely limited and unstable deodorization effect. While activated carbon has a strong adsorption capacity for polar odorous substances, its adsorption capacity for hydrophobic VOCs is extremely low. Furthermore, the odorous gases produced by domestic sewage are mixtures of multiple components, and single-agent activated carbon adsorption cannot achieve complete removal, resulting in some odorous substances remaining after treatment and the emitted gas still carrying an odor. Therefore, we propose an odor purification device for domestic sewage treatment. Utility Model Content
[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a deodorization and purification device for domestic sewage treatment. This device boasts excellent deodorization performance and overcomes the significant weaknesses of current domestic sewage treatment deodorization technologies. The core issue is that deodorization is generally achieved solely through activated carbon adsorption, resulting in an extremely limited and unstable deodorization method. While activated carbon has a strong adsorption capacity for polar odorous substances, it has a very low adsorption capacity for hydrophobic VOCs. Furthermore, the odorous gases produced by domestic sewage are a mixture of multiple components, and single-component activated carbon adsorption cannot achieve complete removal, leaving some odorous substances remaining after treatment and causing the emitted gas to still have an unpleasant odor.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a deodorization and purification device for treating domestic sewage, comprising a workbench, a housing fixedly connected to the left side of the top of the workbench, a rotating shaft movably connected to the central axis of the top of the housing via a bearing, an ultraviolet germicidal lamp fixedly connected to the bottom of the rotating shaft surface, an ozone generator fixedly connected to the back of the housing, a corrugated pipe connected to one side of the ozone generator, an aeration disc connected to one side of the corrugated pipe, an overflow pipe connected to the top of the right side of the housing, a box connected to one side of the overflow pipe, the bottom of the box fixedly connected to the workbench, and an activated carbon filter plate sealed and inserted into the front of the box.
[0006] Preferably, a motor is fixedly connected to the left side of the top of the housing, a drive shaft is fixedly connected to the output end of the motor, a drive gear is fixedly connected to the surface of the drive shaft, a driven gear meshes with one side of the drive gear, the inner cavity of the driven gear is fixedly connected to the rotating shaft, a fixed plate is fixedly connected to the top of the left side of the housing, a reciprocating screw is movably connected to one side of the fixed plate, a threaded sleeve is threaded to the surface of the reciprocating screw, a movable rod is movably connected to one side of the threaded sleeve, an adjusting plate is movably connected to one side of the movable rod, a horizontal plate is fixedly connected to one side of the adjusting plate, and one side of the horizontal plate is fixedly connected to the aeration disc.
[0007] Preferably, an electrical slip ring is fixedly connected to the top of the rotating shaft, and a bracket is fixedly connected to one side of the electrical slip ring, and one side of the bracket is fixedly connected to the housing.
[0008] Preferably, the top of the fixed plate is movably connected to the reciprocating lead screw via a bearing, and the front and rear sides of the inner cavity of the threaded sleeve are slidably connected to slide rods, with the top of the slide rods fixedly connected to the fixed plate.
[0009] Preferably, a rectangular groove is provided on the left side of the housing, and a sealing ring is fixedly connected to the inner cavity of the rectangular groove.
[0010] Preferably, a water injection pipe is connected to the front of the housing, and a controller is fixedly connected to the right front end of the top of the box.
[0011] Preferably, a timing pulley is fixedly connected to the top of both the reciprocating lead screw and the drive shaft, and a timing belt is engaged on the surface of the timing pulley.
[0012] Compared with the prior art, this utility model provides a deodorization and purification device for domestic sewage treatment, which has the following beneficial effects: 1. This utility model injects sewage through a water inlet pipe. As the liquid level in the inner cavity of the casing rises, it comes into contact with the ultraviolet germicidal lamp. The controller activates the ultraviolet germicidal lamp and ozone generator. Once activated, the ultraviolet germicidal lamp releases ultraviolet light of a specific wavelength. On one hand, the ultraviolet light can directly destroy the molecular structure of malodorous substances in the sewage, initially decomposing them into low-odor or odorless small molecules. On the other hand, the ultraviolet light can kill anaerobic microorganisms that produce malodor in the sewage, reducing the continuous generation of malodorous gases such as hydrogen sulfide and ammonia from the source, thus cutting off the root cause of malodor. The ozone generator... The generated ozone is transported to the aeration disc through a corrugated pipe. The aeration disc evenly releases the ozone into the wastewater in the form of tiny bubbles. Due to its strong oxidizing properties, the ozone reacts with recalcitrant odorous substances such as hydrogen sulfide and ammonia in the wastewater, completely decomposing the odorous components. At the same time, ultraviolet light can excite some of the ozone to generate hydroxyl radicals, further improving the oxidation efficiency of the ozone and ensuring that complex odorous substances are fully decomposed. As the liquid level rises, the treated wastewater in the upper part will be discharged into the inner cavity of the tank through the overflow pipe, and then filtered again through the activated carbon filter plate, thus undergoing multiple treatments, resulting in a good deodorization and purification effect.
[0013] 2. This utility model starts the motor through the controller, which drives the drive shaft to rotate. The drive shaft drives the driving gear to rotate, which in turn drives the driven gear to rotate. The driven gear drives the rotating shaft to rotate, which in turn drives the ultraviolet germicidal lamp to rotate. While agitating the water, this also ensures good contact between the ultraviolet germicidal lamp and the water, thereby improving the deodorization effect. Through the cooperation of the synchronous pulley and synchronous belt, the drive shaft also drives the reciprocating screw to rotate. The reciprocating screw drives the threaded sleeve to move, which in turn drives the movable rod to move. The movable rod drives the adjusting plate to move, which in turn drives the horizontal plate to move. The horizontal plate drives the aeration disc to move, thereby adjusting the position of the aeration disc and ensuring uniform bubble distribution. Attached Figure Description

[0019] The specific function of this technical solution is as follows: Wastewater is injected through the water injection pipe 3. As the liquid level in the inner cavity of the shell 2 rises, it comes into contact with the ultraviolet germicidal lamp 9. The controller 24 activates the ultraviolet germicidal lamp 9 and the ozone generator 10. After activation, the ultraviolet germicidal lamp 9 releases ultraviolet light of a specific wavelength. On one hand, the ultraviolet light can directly destroy the molecular structure of malodorous substances in the wastewater, initially decomposing them into low-odor or odorless small molecules.

The ozone generator… The ozone generated by 10 is transported to the aeration disc 12 through the corrugated pipe 11. The aeration disc 12 releases the ozone evenly into the sewage in the form of microbubbles.

At the same time, ultraviolet light can excite some ozone to generate hydroxyl radicals, further improving the oxidation efficiency of ozone and ensuring that complex odorous substances are fully decomposed. As the liquid level rises, the treated sewage in the upper part will be discharged into the inner cavity of the tank 22 through the overflow pipe 21, and filtered again through the activated carbon filter plate 23, thus undergoing multiple treatments, resulting in good deodorization and purification effects.

On the other hand, the ultraviolet light can kill anaerobic microorganisms that produce malodor in the wastewater, reducing the continuous generation of malodorous gases such as hydrogen sulfide and ammonia from the source, cutting off the root cause of malodor. The ozone generator 10 produces... The generated ozone is transported to the aeration disc 12 through the corrugated pipe 11. The aeration disc 12 releases the ozone evenly into the sewage in the form of tiny bubbles. Due to its strong oxidizing properties, the ozone reacts with the hydrogen sulfide, ammonia and other difficult-to-degrade odorous substances in the sewage, completely decomposing the odorous components.

The controller 24 starts the motor 4, which drives the drive shaft 5 to rotate. The drive shaft 5 drives the drive gear 6 to rotate, which in turn drives the driven gear 7 to rotate. The driven gear 7 drives the rotating shaft 8 to rotate, which in turn drives the ultraviolet germicidal lamp 9 to rotate. This agitates the water and ensures good contact between the ultraviolet germicidal lamp 9 and the water, thereby improving the deodorization effect. Through the cooperation of the synchronous pulley 15 and the synchronous belt 16, the drive shaft 5 also drives the reciprocating screw 14 to rotate.
