Abstract:

The photocatalytic mechanism of degrading the organic pollutant in wastewater by nanometer TiO2 is introduced. The influential factors on the photocatalytic activity of nanometer TiO2, such as particle size, crystallite, doping, load of nanometer TiO2, and photocatalyst content, pH value, adding oxidizer, inorganic salts, light intensity, etc. in the system of wastewater treatment are also discussed. Potential applications of nanometer TiO2 in industrial wastewater treatment are previewed. It is considered that the development direction in the future is to enhance the photocatalytic efficiency of nanometer TiO2, expanding the scope of its absorption spectrum and developing its load technology

Key words: wastewater reuse, membrane separation, pathogenic microorganism
