Abstract

The invention discloses application of photocatalyst of TiO2 (titanium dioxide) loaded on a glass fiber fabric to treating microcystin. The glass fiber fabric serves as a catalyst carrier with a load of 0.8-1.2g / 200cm2, and the TiO2 loaded on the glass fiber fabric is of a P25 type. After the TiO2 is treated, hydroxyl radicals are obviously increased during photocatalysis, so that oxidative degradation of the microcystin by means of photocatalysis is improved. Besides, the TiO2 has high photocatalytic activity and is higher in reuse rate.

Description

technical field [0001] The invention relates to a photocatalytic oxidation method of microcystin, using glass fiber cloth (FGC) as a fixed TiO 2 The carrier for improving its photocatalytic activity belongs to the fields of water treatment technology and environmental pollution control technology. Background technique [0002] In recent years, with the aggravation of eutrophication in lakes, cyanobacteria "blooms" have occurred frequently, and cyanobacteria will secrete microcystins in the process of metabolism or after the rupture of algae, polluting water sources, and directly threatening human health. Conventional water treatment processes are difficult to completely remove microcystins from water bodies, and even cause algal cell rupture and release algal toxins into water bodies, so further advanced treatment is required to remove them. [0003] The conventional water treatment method currently adopted to remove microcystins has the following disadvantages: [0004] a...
