Abstract

The invention relates to an oxidation reactor based on ultraviolet light and catalyst catalysis, which is characterized in that the oxidation reactor comprises an equipment body consisting of a cylindrical tank body and end sockets at two ends, a light source mounting tube and a communicating tube are arranged on each end socket, the light source mounting tube is arranged in the center of each endsocket, and a sealing gland is arranged at the end part of each light source mounting tube; a liquid inlet tube is arranged on the side wall of the lower end of the tank body; an aeration plate is mounted in the equipment body and is positioned below the liquid inlet tube; a plurality of aeration heads are uniformly arranged on the aeration plate, and a middle hole is formed in the center of theaeration plate; a glass tube is mounted in the tank body and penetrates through the middle hole of the aeration plate; the two ends of the glass tube are respectively inserted into the light source mounting tubes and are fixed by the sealing glands; a lamp holder is arranged in the glass tube at the lower end socket; and an ultraviolet light source is inserted into the lamp holder in the glass tube. The equipment is simple in structure, it can be guaranteed that the ultraviolet lamp is used under the pressurization condition, the problems of heating and heat dissipation of the ultraviolet lampare solved, and the service life of the light source is prolonged.

Description

technical field [0001] The invention relates to an oxidation reactor based on ultraviolet light and catalyst catalysis, and belongs to the technical field of waste water treatment equipment. Background technique [0002] The catalytic wet oxidation method uses oxygen or air as an oxidant in the liquid phase under the conditions of high temperature (80-180°C), high pressure (1-5MPa) and the presence of a catalyst to remove dissolved or suspended organic matter or A method in which reduced inorganic substances are oxidized and decomposed into non-toxic and harmless substances such as carbon dioxide, water, and nitrogen. Although this technology has the characteristics of high treatment efficiency, short reaction time, fast oxidation speed, and no secondary pollution, it has high requirements for equipment, operation and catalyst selection, and the overall operating cost is relatively high. [0003] The photocatalytic oxidation method is excited by ultraviolet light to generat...

AI Technical Summary

Problems solved by technology

This technology has the advantages of mild reaction conditions and strong oxidation ability, but its disadvantages are also obvious. One is that the absorption range of ultraviolet light is narrow, and the utilization rate of light energy is low. The other is that the light transmittance is poor, and some wastewater ( Some suspended solids and darker chroma in printing and dyeing wastewater are not conducive to the transmission of light, which will affect the photocatalytic effect
