Embodiment Construction

[0020] see figure 1 , the waste water and waste gas photodegradation device of the present invention includes a microstructure polymer optical fiber monomer 1 for the photodegradation of waste water and waste gas. The matrix 2 is arranged in the outer cladding 4, and the optical fiber matrix 2 is provided with a channel 3, and the inner surface of the channel 3 is provided with a titanium dioxide nanoparticle layer 5, and the preferred method is to arrange the titanium dioxide nanoparticles on the inner surface of the channel 3 in the form of a film superior.

[0021] There is at least one tunnel 3 and there may be hundreds of tunnels. When there are hundreds of tunnels 3, the tunnels 3 form a periodic distribution of the characteristics of the microstructured optical fiber.

[0022] see figure 2 , using sunlight as a light source from the direction of the optical fiber cladding of the microstructure polymer optical fiber monomer 1 forming the waste water and waste gas phot...

Abstract

The invention relates to a waste water and waste gas photodegradation apparatus. The apparatus comprises a microstructure fiber monomer; the microstructure fiber monomer comprises a fiber substrate, air pore channels and a cladding; the fiber substrate is arranged in the cladding; air pore channels are formed in the fiber substrate; and titanium dioxide nano-particles are arranged on the interior surfaces of the air pore channels. The apparatus greatly improves the loading rate of the titanium dioxide photocatalyst, and greatly enlarges the light receiving area so that the treatment system scale can be infinite and the apparatus lays the foundation for constructing one set of microstructure dispersion fiber load-based nano titanium dioxide photocatalysis waste water and waste gas treatment system; and a permeable ultraviolet light dispersion microstructure polymer fiber load titanium dioxide enables the apparatus to efficiently absorb ultraviolet light on long-distance side, further enlarge the light receiving area and improve the photocatalysis efficiency.

Description

technical field [0001] The invention relates to a waste water and waste gas treatment device and its system, in particular to a waste water and waste gas photodegradation device and its system. Background technique [0002] Titanium dioxide is a semiconductor that can be activated by ultraviolet light. When exposed to ultraviolet light, titanium dioxide is able to remove poisons from fluids, including air and water, breaking down harmful pollutants into environmentally acceptable by-products. For example: titanium dioxide can decompose tar, organic matter, bacteria, virus, mold and other organic matter in smoke. In the process of photooxidative degradation, the larger the reactive surface area, the better, so that a large amount of sewage and waste gas can be treated. [0003] In the 1990s abroad, it was proposed to use silica optical fiber modified by titanium dioxide photocatalyst as the propagation medium of ultraviolet light to construct a fiber-optic photocatalytic re...
