Research Progress on the Application of Nanometer TiO_2 Photoelectrocatalysis Technology in Wastewater Treatment

摘要

The application of nano-TiO2 photoelectrocatalytic oxidation technology for pollutant degradation is a hot research topic. It is one of the most effective techniques for the Advanced Oxidation Technology to oxidize the refractory pollutants in the wastewater. Because the nano-TiO2 photoelectrocatalytic oxidation technology has a strong oxidation capacity, low cost, and non-toxicity, it has become the most potential application in the wastewater treatment. This article describes the application and research progress of the nano-TiO2 photoelectrocatalytic oxidation technology in the treatment of industrial wastewater, agricultural wastewater and land fill leachate in the recent years. Using the nano-TiO2 photoelectrocatalytic oxidation technology to treat different pollutants was summarized. It points the direction of nano-photocatalytic Oxidation Photocatalyst Oxidation technology in future water treatment application technology.
