Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to an ozone sterilization device for sewage treatment. Background Art

[0002] Sewage contains a large amount of organic matter, inorganic matter, pathogenic microorganisms and various harmful chemicals. If it is discharged directly into natural water bodies without proper treatment, it will not only seriously pollute the environment, but also may cause the spread of waterborne diseases, threatening human health and ecological balance. With the continuous reduction of water resources, sewage reuse technology has also been rapidly developed. After a series of treatments, sewage can be used for urban greening irrigation, street washing, landscape water, and even converted into domestic water. In addition to the ordinary physical and chemical methods for treatment, if sewage treatment is to be reused, it is also necessary to sterilize the sewage. Current methods for sterilizing sewage include ultraviolet sterilization, high-temperature sterilization, chlorination sterilization, and ozone sterilization. Ozone sterilization refers to the process of introducing ozone into sewage for sterilization. It has attracted widespread attention due to its high efficiency, rapidity, broad-spectrum sterilization ability, and zero-residue characteristics. In addition to its effective sterilization capabilities, ozone sterilization can also remove odor, color, and some organic pollutants in water. Currently, when ozone sterilization is used in sewage treatment, most ozone generators are fixed, and the ozone generated can only be introduced into a fixed position in the sewage, which cannot ensure that the ozone and sewage are fully and evenly mixed. The ozone sterilization effect is not ideal. Utility Model Content

[0021] The utility model discloses an ozone sterilization device for sewage treatment, which can be installed on a sewage treatment tank as a whole for use. When in use, the position of the U-shaped frame 3 is adjusted according to the size of the sewage treatment tank so that the U-shaped frame 3 can be clamped on the upper side wall of the sewage treatment tank to achieve the fixation of the circular track 1, and then the mobile trolley 6 can be opened. The mobile trolley 6 will drive the ozone generator 4 to move, so that the ozone generator 4 can move circumferentially along the sewage treatment tank. The ozone generated by the ozone generator 4 can enter the sewage through the horizontal pipe 7, the horizontal telescopic pipe 8, the vertical pipe 9, the vertical telescopic pipe 10, and the lifting pipe 11 in sequence. Since the position of the ozone generator 4 will change, the position where the ozone enters the sewage will also change, avoiding the problem of uneven mixing of ozone and sewage due to injection of ozone at the same position.

[0026] The hollow plate 17 is used to support the horizontal telescopic tube 8. Under the synchronous limitation of the electric push rod 13 and the force-bearing plate 12, the horizontal telescopic tube 8 can be prevented from bending due to the action of gravity. When the vertical tube 9 moves horizontally following the force-bearing plate 12, the hollow plate 17 will also move along the bearing plate 16, and the bearing plate 16 can be used to limit the hollow plate 17.

[0027] Preferably, the ozone delivery mechanism further includes an aeration head 18 , and the aeration head 18 is disposed at the bottom end of the lifting pipe 11 .

The electric wheel 20 will drive the mobile box 19 and the ozone generator 4 on the mobile box 19 to move along the annular groove 5. In order to ensure the smooth movement of the mobile box 19, an auxiliary wheel 21 is provided on its outer wall.
