Description

Technical Field

[0001] The utility model belongs to the technical field of wastewater treatment, and particularly relates to a UV photocatalytic oxidation wastewater treatment device. Background Art

[0002] In industrial wastewater, there are generally two kinds of impurities, inorganic substances and organic substances. The methods for treating organic substances mainly include: activated carbon adsorption, ion exchange resin, and UV photocatalytic oxidation. UV light is ultraviolet light. The wavelength range of ultraviolet light is between 100 and 400 nanometers. It is an electromagnetic wave between X-rays and visible light. It has a bactericidal effect while also damaging human cells and needs to be used with caution in production and life. UV photocatalytic oxidation is to irradiate wastewater with high-intensity and high-brightness ultraviolet light beams to change its molecular chain structure, so that the molecular chains of inorganic or organic high-molecular compounds are degraded and transformed into low-molecular compounds under the irradiation of high-intensity and high-brightness ultraviolet light beams.

[0003] In the existing related technologies, the cylinder is generally fixed and the wastewater is turbid. The ultraviolet light only acts on the outer side of the whole wastewater. When treating wastewater, the flow rate of the wastewater is reduced and adjusted according to the turbidity of the wastewater itself, and the wastewater cannot be effectively and thoroughly treated. Therefore, it is urgent to design a UV photocatalytic oxidation wastewater treatment device to solve these problems. Summary of the Utility Model

[0029] In this embodiment: The wastewater treatment mechanism 3 includes a rotating shaft 301 disposed inside the auxiliary mechanism 2. A power source 302 is provided on one side of the rotating shaft 301, and the power source 302 is a driving motor. A belt 3021 is installed between the rotating shaft 301 and the power source 302. A stirring cylinder assembly 303 is provided on the rotating shaft 301, and a stirring blade assembly 304 is arranged inside the stirring cylinder assembly 303. A quartz glass tube 305 is vertically disposed at the rear of the stirring cylinder assembly 303. A UV lamp 306 is installed inside the quartz glass tube 305. A power plug pin 3071 is provided below the UV lamp 306. A sealing ring 307 is installed between the UV lamp 306 and the quartz glass tube 305. A heating tube 310 is provided on the front side of the quartz glass tube 305. The UV lamp tube 306 is installed inside the quartz glass tube 305, which is convenient for preventing the sewage from corroding the UV lamp tube 306. A water body purification tank 308 is provided below the auxiliary mechanism 2, and a purification body assembly 309 is arranged inside the water body purification tank 308. The stirring cylinder assembly 303 includes a cylinder body 3031 provided on the rotating shaft 301.

The inside of the UV lamp 306 is filled with low-pressure mercury vapor, which can generate ultraviolet wavebands.

[0030] Working principle: When in use, first start the power source 302 to drive the rotation of the rotating shaft 301 through the belt 3021, and at the same time drive the stirring drum assembly 303 and the stirring blade assembly 304 to rotate. Meanwhile, turn on the UV lamp 306 in the quartz glass tube 305 to generate ultraviolet rays, and turn on the heating tube 310 for preheating. Connect the wastewater pipe 205 with the wastewater tank, turn on the water pump 204 to pump the wastewater into the box body 202 through the wastewater pipe 205. Through the guide plate 206 and the grate plate 208, the wastewater flows into the box body 202. After a certain period of time, the wastewater rolls under the slow stirring of the stirring drum assembly 303 and the stirring blade assembly 304 during rotation. The stirring of the wastewater by the stirring drum assembly 303 and the stirring blade assembly 304 increases the reaction time for the wastewater to absorb ultraviolet rays, facilitating the oxidation of the sewage. At the same time, the UV lamp 306 generates ultraviolet rays and the heating tube 310 acts on the wastewater together, enabling the wastewater to be fully sterilized. In order to prevent the wastewater from damaging the UV lamp 306, the quartz glass tube 305 and the sealing ring 307 are used to protect the UV lamp 306. The wastewater treated by sterilization and oxidation passes through the purification body assembly 309 in the water purification tank 308 provided below the box body 202 to purify the wastewater, and then through the next process, which helps to improve the working quality of the wastewater treatment device.
