The characteristics of nano-TiO2 were summarized in this paper. The reaction mechanisms and research progresses for drinking water treatment by nano-TiO2 photocatalytic oxidation, nano-TiO2 catalytic ozonation, and nano-TiO2 photocatalytic ozonation were reviewed. The characteristics and treatment effects of these three nano-TiO2 technologies were compared. Compared to other technologies, the combination of nano-TiO2 photocatalytic oxidation and ozonation showed a good synergy. The problems of nano-TiO2 technology existing in the research were analyzed and the future development directions of nano-TiO2 materials used in drinking water treatment were prospected.
