Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a high-efficiency ozone oxidation device for wastewater decolorization. Background Technology

[0002] With increasing attention to the environment of tap water sources and the reuse of treated wastewater, wastewater decolorization has become a key focus. Due to the large amount of humic substances in wastewater, the average color of the water is 10 degrees, with a maximum of 20 degrees. Such color cannot be adequately removed by general coagulation, sedimentation, and sand filtration processes. Therefore, decolorization is an important process in wastewater treatment. Ozone is a strong oxidant that can break down or change the chemical structure of chromophores in wastewater, thereby achieving the purpose of wastewater decolorization. At the same time, through strong oxidative decomposition, it promotes the decomposition of COD in the settled wastewater, which is difficult to biodegrade, into small molecule organic matter that can be biodegraded.

[0003] The prior art, CN212982566U, discloses an ozone oxidation device, including an ozone oxidation tower. An aeration head is installed inside the tower, and the surface of the aeration head is coated with a fluorocarbon-lined material layer to prevent organic matter and silicon contamination. By coating the surface of the aeration head with a fluorocarbon-lined material layer resistant to organic matter and silicon contamination, pollutants are not adsorbed on the surface of the aeration head, preventing clogging and extending the service life of the aeration head.

[0004] However, the ozone oxidation device has a single aeration point during use, which prevents ozone from mixing quickly and thoroughly with the wastewater. This results in insufficient reaction between some wastewater and ozone, incomplete wastewater treatment, and reduced wastewater treatment efficiency. Therefore, a high-efficiency ozone oxidation device for wastewater decolorization is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a high-efficiency ozone oxidation device for wastewater decolorization, which has advantages such as easy and thorough mixing. It solves the problems of existing ozone oxidation devices where the aeration position is singular, ozone cannot be quickly and thoroughly mixed with wastewater, resulting in insufficient reaction between some wastewater and ozone, incomplete wastewater treatment, and reduced wastewater treatment efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency ozone oxidation device for wastewater decolorization, comprising a wastewater tank and an ozone generator, wherein an aeration pipe is provided inside the wastewater tank, multiple aeration heads are provided on the outside of the aeration pipe, and a mixing mechanism is provided on the upper side of the aeration pipe.

[0007] The mixing mechanism includes an electric push rod, on which an installation plate is fixedly mounted. A connecting rod is fixedly connected to the bottom of the installation plate, and the lower end of the connecting rod is fixedly connected to an aeration pipe. A spline sleeve is rotatably mounted on the inner side of the installation plate, and a spline shaft is movably inserted into the inner side of the spline sleeve. A drive motor is provided on the upper side of the spline shaft, and an installation shaft is fixedly mounted on the lower end of the spline sleeve. Blades are fixedly mounted on the outer wall of the installation shaft.

[0008] Furthermore, a drain pipe is installed on the outer wall of the sewage tank, and a connecting hose is installed between the ozone generator and the aeration pipe.

[0009] Furthermore, a fixing frame is fixedly installed on the top of the sewage tank, and the electric push rod is fixedly installed on the top of the fixing frame.

[0010] Furthermore, the drive motor is fixedly mounted on the top of the mounting bracket, and the upper end of the spline shaft is fixedly connected to the output shaft of the drive motor.

[0011] Furthermore, the spline sleeve extends through the inner side of the mounting plate, and the outer wall of the spline sleeve is connected to the mounting plate via a bearing.

[0012] Furthermore, a first guide rod is fixedly installed inside the sewage tank, and a movable sleeve is fixedly installed on the outer wall of the aeration pipe, with the movable sleeve fitted onto the outer wall of the first guide rod.

[0013] Furthermore, a second guide rod is fixedly connected to the top of the mounting plate, and the second guide rod extends to the upper side of the fixing frame.

[0014] Compared with the prior art, this utility model provides a high-efficiency ozone oxidation device for wastewater decolorization, which has the following beneficial effects:

[0015] This high-efficiency ozone oxidation device for wastewater decolorization delivers ozone into the wastewater tank via a connecting hose, aeration pipe, and aeration heads. Activating an electric push rod moves the mounting plate and connecting rod, simultaneously causing the spline sleeve to slide along the outer wall of the spline shaft. The connecting rod also moves the aeration pipe, adjusting the position of the aeration heads. Furthermore, activating a drive motor rotates the spline shaft, causing the spline sleeve to rotate synchronously, and simultaneously rotating the mounting shaft and blades. This ensures thorough mixing of wastewater and ozone, improving wastewater treatment efficiency. It solves the problem of existing ozone oxidation devices where the aeration position is singular, ozone cannot quickly and thoroughly mix with wastewater, resulting in incomplete reaction and inadequate wastewater treatment, thus reducing overall wastewater treatment efficiency.
