Abstract

The invention relates to an ultraviolet ray and secondary ozone water treatment device. The water treatment device is composed of a shell, a water inlet, a water outlet, an air inlet, a center outer casing pipe, a center inner casing pipe, an ultraviolet lamp tube and an aeration perforated pipe. The water inlet, the water outlet and the air inlet are arranged on the shell and the center outer casing pipe, the center inner casing pipe, the ultraviolet lamp tube and the aeration perforated pipe are arranged inside the shell. The water inlet is arranged at the lower part of the shell. The water outlet is arranged at the upper part of the shell. The ultraviolet lamp tube, the center inner casing pipe and the center outer casing pipe are sleeved from inside to outside in order and are arranged in the central position of the shell. The air inlet is communicated with the center outer casing pipe. The aeration perforated pipe is connected with the bottoms of the center inner casing pipe and the center outer casing pipe. Compared with the prior art, the water treatment device shows good effects of killing bacteria and viruses in water, and decreasing the color degree of water. The water treatment device is simple in structure and easy to operate and use. The water treatment device can be used for sterilization and disinfection treatment and decolorizing treatment of water, and has a wide range of applications in the field of water treatment. [0]

Description

technical field [0001] The invention relates to a water treatment device, in particular to an ultraviolet and secondary ozone water treatment device. Background technique [0002] Ultraviolet rays and ozone both have strong sterilization and disinfection effects, and ozone has a strong oxidizing ability, so it is widely used in the fields of water treatment and environmental protection. The existing technology is to inject the ozone generated by the ozone generator into the water treatment device, and at the same time irradiate ultraviolet rays to achieve the treatment effect of combining ozone and ultraviolet rays. This method is generally called "advanced oxidation method". Because the existing technology needs to be equipped with an ozone generator, the water treatment device is complicated and expensive. [0003] The Chinese patent application number 200510132947.9 discloses a device that uses ozone and ultraviolet rays to treat harmful substances, and is used to remove...
