Abstract

The invention relates to an ultraviolet sterilization device used for water treatment and coated with photocatalytic materials, belonging to the technical field of water treatment. The ultraviolet sterilization device comprises a cylinder and an ultraviolet lamp tube, wherein a water inlet is formed in one side of the upper part of the cylinder, a water outlet is formed in the other opposite side of the lower part of the cylinder, a cylinder cover is arranged on the cylinder, the ultraviolet lamp tube is arranged at the center of the cylinder, the upper end of the ultraviolet lamp tube is fixed on the cylinder cover, a left baffle and a right baffle are respectively a left semicircular baffle and a right semicircular baffle, the arc-shaped sections of a plurality of left semicircular baffles are evenly distributed and fixed on the left-side cylinder wall along with the axial direction of the cylinder, the arc-shaped sections of a plurality of right semicircular baffles are evenly distributed and fixed on the right-side cylinder wall along with the axial direction of the cylinder, the left semicircular baffles and the right semicircular baffles are arranged at intervals along with the axial direction of the cylinder. The surfaces of the cylinder, the cylinder cover, the plurality of right semicircular baffles and the plurality of left semicircular baffles are coated with the photocatalytic materials. According to the ultraviolet sterilization device, the sterilization efficiency can be improved, the material consumption and energy consumption cost can be saved, and the capability of sterilization and water treatment can be improved under the same conditions.

Description

technical field [0001] The invention relates to an ultraviolet sterilizing device coated with a photocatalytic material for water treatment, which belongs to the technical field of water treatment. Background technique [0002] With the rapid development of society, the discharge of industrial wastewater and domestic sewage is increasing year by year. These wastewater and sewage contain a large number of viruses and bacteria. Random discharge will cause environmental pollution, endanger the organisms in the water, and even humans and animals. Therefore, it is very necessary before discharge. Sterilize. Now the conventional sterilization method one is ultraviolet irradiation, and the second method is to rely on chemical agents. The conventional sterilization device is to place an ultraviolet lamp tube in a closed container, or use a dosing pump to add chemical agent solution to the main water outlet pipe. The result is either The sterilization efficiency is not ideal, or the...
