Description

Technical Field

[0001] The utility model relates to the technical field of photoelectric catalysis, in particular to a photoelectric catalytic sewage treatment device. Background Art

[0002] In the process of photoelectrocatalytic sewage treatment, one or more semiconductor materials are usually used as photocatalysts. When these photocatalysts are irradiated with light, if the energy of the photon is greater than or equal to the bandgap width of the semiconductor material, the photocatalyst will absorb the photon energy, so that the electrons in the valence band are excited to jump to the conduction band, forming photogenerated electrons (e^-). At the same time, corresponding holes (h^+) are left in the valence band. These photogenerated electrons and holes have strong redox ability and can react with organic pollutants in sewage to degrade them into harmless substances.

[0003] The photoelectrocatalytic sewage treatment device in the prior art generally needs to be equipped with a light source, and the light source generally adopts an ultraviolet lamp. Placing the ultraviolet lamp inside the device is likely to leave precipitation or attachments on the lamp wall, affecting the lighting effect, and further affecting the catalytic effect of the photocatalytic component. For this reason, we propose a photoelectrocatalytic sewage treatment device. Utility Model Content
