Abstract

The invention discloses a fiber filtering felt for photocatalytic sewage treatment, and a preparation method thereof, wherein the photocatalytic fiber filtering felt is obtained by using glass fiber as a substrate and using a photocatalytic material as a film plating layer, and the photocatalytic material is a mixed modified photocatalyst. According to the present invention, the prepared fiber filtering felt has characteristics of low wind resistance, good light transmittance, good visible light response, excellent photocatalytic degradation performance and the like.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a fiber filter felt for photocatalytic sewage treatment and a preparation method thereof. Background technique [0002] Photocatalytic technology uses ultraviolet light to irradiate photocatalytically active semiconductor materials to generate photogenerated holes and photogenerated electrons on the surface. Photogenerated holes and the hydroxyl radicals generated after being captured have strong oxidizing ability and can almost All organic pollutants. Photocatalytic technology is characterized by effective use of light energy, easy operation, and no secondary pollution, and is widely used in the field of air purification. In terms of morphology, photocatalysts can be divided into two types: powder type and supported type. The former has relatively high catalytic activity, but the fine powder is easy to agglomerate in the process of air purification, which a...
