NOVELTY - Preparing optical fiber fabric with function of photocatalytic degradation of antibiotic and dye wastewater involves using yarn containing bismuth (Bi)-based and titanium dioxide (TiO2)-based photocatalyst, mixing finished side-emitting optical fiber, weaving to obtain non-fixed-point photocatalytic fabric, or using ordinary yarn sand finished side-emitting optical fiber to mix, weaving to obtain optical fiber fabric, and loading Bi-based and TiO2-based photocatalyst on the outer surface of the optical fiber fabric to obtain side-emitting non-fixed-point photocatalytic fabric. USE - Method for preparing optical fiber fabric with function of photocatalytic degradation of antibiotic and dye wastewater. ADVANTAGE - The method can solve the problem that the traditional photocatalyst easily causes secondary pollution to the water body and low catalytic performance caused by poor dispersibility, and can realize the degradation of the water body antibiotic/dye in the dark environment. The optical fiber in the fabric containing different photocatalyst is respectively connected to different light source, which can realize the simultaneous degradation of various antibiotics/dyes, greatly improve the photocatalytic efficiency, and have broad application prospect.
