Photocatalytic fiber water treatment equipment with built-in light path and using method thereof

Abstract

The invention discloses photocatalytic fiber water treatment equipment with a built-in light path, which comprises a treatment tank and a plurality of photocatalytic fibers arranged in the treatment tank, an ultraviolet lamp tube is arranged at the bottom of the treatment tank, a traction assembly is arranged in the treatment tank, the photocatalytic fibers are connected with the traction assembly, and the ultraviolet lamp tube irradiates the end surfaces of the photocatalytic fibers; the photocatalytic fiber is of a skin-core structure and comprises a core layer and a skin layer wrapping thecore layer, the core layer at least comprises transparent resin, and the skin layer at least comprises a transparent fiber-forming high polymer and nano titanium dioxide particles mixed into the transparent fiber-forming high polymer. The photocatalytic fibers arranged in the treatment tank are used for treating sewage, the recycling is easy, the problem of catalyst solid residue pollution is avoided, meanwhile, the exposure rate of titanium dioxide particles can be increased by stretching the photocatalytic fibers, sewage is continuously treated within a certain period of time, and a catalytic reaction is controlled to a certain extent.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a photocatalytic fiber water treatment device with a built-in optical path and a use method thereof. Background technique [0002] Sewage treatment is the process of making sewage meet specific discharge standards, or the water quality required for reuse. With the increasing shortage of water resources and the gradual increase of water pollution, sewage treatment has become an important way of water resource protection. [0003] A photocatalyst is a substance that does not change itself under the irradiation of light, but can promote chemical reactions. Photocatalyst converts light energy into chemical reaction energy, produces catalysis, and excites surrounding water molecules and oxygen into highly oxidative hydroxyl radicals and superoxide ion radicals, which can decompose organic substances that are harmful to the human body and the environment. Substances and some...

Problems solved by technology

[0005] At present, due to the pollution-free and sustainable nature of photocatalysts, they are used in the field of sewage treatment in a large number of practical operations, but the main method is to directly throw granular photocatalysts into sewage, which is difficult to recycle and increases costs. endless secondary pollution

And the photocatalyst needs to work under good lighting conditions. In some cases, it is difficult to arrange the light source when the visibility in the sewage is low and the light transmittance is poor.
