Abstract

The invention discloses a solar photocatalytic degradation device, belongs to the technical field of sewage treatment and particularly relates to a device which solves the problems that a sewage treatment device is high in energy consumption, high in price and prone to secondary pollution by using a modified photocatalyst responsive to ultraviolet visible light and taking sunlight as a light source to drive reactions to degrade pollutants. The device mainly comprises reaction tanks, hollow pipes, air ejecting pipes, an air pump, a transparent stair-shaped photocatalytic reaction chute, circular arc baffles, a water conveying pipe, a water pump, a water collecting pool and a solar cell panel. The reaction tanks are used for providing sites for homogenizing and processing sewage, the hollow pipes are used for carrying ultraviolet visible light modulator tubes, the air ejecting pipes and the air pump are used for aerating the reaction tanks, the transparent stair-shaped photocatalytic reaction chute is used for providing a photocatalytic degradation site, the circular arc baffles are used for homogenizing and slowing down a sewage solution, the water conveying pipe and the water pump are used for conveying the sewage in the water collecting pool into the reaction tanks, the water collecting pool is used for collecting degraded sewage, and the solar cell panel is used for storing electric energy. The sunlight is mainly used, and the device has the advantages of being clean, efficient, free of secondary pollution, controllable in reaction atmosphere, high in light source utilization rate and the like.

Description

technical field [0001] The invention relates to a solar photocatalytic degradation device, which belongs to the technical field of sewage treatment. Background technique [0002] With the rapid development of the economy, domestic and industrial sewage discharges are gradually increasing, and the problem of water pollution is becoming more and more serious. The pollutants in industrial sewage and general domestic sewage mainly include organic dyes, inorganic ions, solid particles or colloids, microorganisms, etc. For wastewater containing these pollutants, the usual treatment methods include flocculation, electrolytic deposition, physical adsorption (including filtration), chemical treatment, microbial degradation, etc. These traditional sewage treatment methods are difficult to completely purify soluble harmful substances and fine particles in sewage, and there are problems such as high energy consumption, secondary pollution, and low treatment efficiency, and further trea...
