Application of Solar Energy-Titanium Dioxide Photo Catalytic Technology in Water Treatment / 环境与健康杂志

The recent developments in purification and disinfect of drinking water as well as wastewater treatment adopting solar energy-titanium dioxide(TiO2)catalytic technology are introduced in general in the present review. The advantages of this technology are titanium dioxide catalytic agent with strong sunlight absorption in near ultraviolet ray range, lasting catalytic reaction, chemical stable and innocent for human and environment. The oxidizer produced during ray catalytic has strong oxide action that can kill most microorganisms and decompose most organic pollutants. This technology has widespread practical value in the remote areas and rural areas because it does not consume electric energy
