Abstract

The invention relates to particle electrode catalytic filler of a three-dimensional electrolysis-photocatalysis coupling reactor and a preparation method thereof. The particle electrode filler is prepared from TiO2 loaded activated carbon and film coated activated carbon, wherein a mass percent of the TiO2 loaded activated carbon is 70 to 80%, a mass percent of the film coated activated carbon is20 to 30%, the TiO2 loaded activated carbon is prepared by the steps of pretreating activated carbon by acid and base and loading a semiconductor, and the film coated activated carbon is prepared by the steps of pretreating activated carbon by acid and base and dipping the activated carbon by a cellulose acetate solution.

Description

technical field [0001] The invention belongs to the field of water treatment and water pollution prevention and control, and in particular relates to a particle electrode catalytic filler for a three-dimensional electrolysis-photocatalysis coupling reactor and a preparation method thereof. Background technique [0002] Chemical, dye, plastic, pharmaceutical and other factories produce a variety of organic wastewater that is difficult to biodegrade. These pollutants have stable chemical properties, high chemical oxygen consumption, and are easy to accumulate in organisms, which are toxic to humans and other organisms. Its stable chemical structure and biological toxicity hinder the metabolism of microorganisms and are difficult to remove by microorganisms. [0003] Electrochemical treatment of this type of wastewater has the advantages of less chemical consumption, simple operation, and environmental friendliness. It is a green technology with advanced technology and no secon...
