AI Technical Summary

Technical Problem

In the prior art, a contaminant adhesion layer is formed on the surface of the light-separating tube and the light-transmitting module, resulting in a gradual decrease in the photocatalytic effect and affecting the photocatalytic effect and efficiency.

Method used

A circulating wastewater photocatalytic treatment device is designed. The fulcrum shaft is set eccentrically with respect to the rotation axis of the guide frame, and the ultraviolet beam rod is driven to rotate and slide in the circumference to realize the stirring of the wastewater. At the same time, the adhesions on the outer wall of the ultraviolet beam rod are scraped off to keep the photocatalyst clean.

Benefits of technology

It effectively improves the cleaning problem of photocatalysts, improves the efficiency and adequacy of photocatalytic action, and extends the service life of the device.
