摘要

The UV light-titanium dioxide oxidation technology disinfection of microorganism was studied under different system flow rate, TiO2 produce strong oxidizing hydroxyl radicals under irradiation of UV light,it's more efficient compare with traditional ultraviolet light sterilization.The variation of total number of bacteria, heterotrophic bacteria and Legionella pneumophila in the disinfection process of microorganism was investigated.The results show that when the flow rate through UV light-titanium dioxide oxidation technology turn to 1.2m3/h.The killing rate of total number of bacteria and heterotrophic bacteria is 99.2%and 98%, and Legionella pneumophila was killed completely.
