Oxidation Technology

Advanced oxidation technology is attracting attention as an effective method of water treatment that can degrade various organic pollutants. The combination of photocatalysis (UV) and ozone (O3) and titanium dioxide (TiO2) is a promising advanced oxidation technology. The combination of ozone, hydrogen peroxide, ultraviolet light and other oxidants for catalytic oxidation is also the current mainstream advanced oxidation technology. They can effectively degrade emerging water pollutants and alleviate water pollution problems. Titanium dioxide, hydrogen peroxide, and ozone are all popular catalysts because of their low cost, non-toxicity, strong oxidizing ability, and easy contact with various surfaces.

Oxidation Technology

Advanced Oxidation Technology (AOPs) is a new water treatment process, especially, for refractory organic wastewater treatment. This paper emphatically introduced the mechanism and research progress of Fenton oxidation method and Fenton method, ozone oxidation, photocatalytic oxidation, wet air oxidation, supercritical water oxidation, electrochemical oxidation, and ultrasonic oxidation technology. The cheaper and more effective catalyst and oxidant is the main development trend in the future AOPs.

Treatment Application

TiO2 catalyst is n-type semiconductor material. As long as the semiconductor absorbs photons of no less than the band gap width，it enters the excited state together with the formation of light-induced hole in the valence band simultaneously. It is perfectly capable of capturing electronic,and the photo-induced electron e- in the conduction band also has high activity to form a redox system in the semiconductor surface through which most of the organic pollutants and partial inorganic pollutants eventually degrade into innoxious substances. It describes the application of photocatalytic oxidation technology in the field such as treatment of industrial wastewater (inorganic polluted water; dye wastewater; papermaking wastewater; pesticide wastewater; oily wastewater) and drinking water. The research shows that various indexes (chromaticity; COD; mineralization rate; bacteria inactivation rate, etc.) of this technology in water treatment application have achieved the required standards.
