Title: Research on Influencing Factors of Photoreactivation in Urban Sewage Treatment by UV Disinfection
Abstract: Test using CS-type UV sterilizer to do experimental study on the urban sewage , mainly research the influence of the placement time under natural light and the UV dose on photoreactivation. The results show that when disinfection ultraviolet dose is equal, bacteria photoreactivation phenomenon is more obvious with the increase of the placement time of water samples under natural light . When the placement time reaches at 3h, bacteria photoreactivation phenomenon is the most obvious. Under the same placement time, the ratio of bacteria photoreactivation decreases gradually with the increase of UV dose. When UV dose reaches at 80mJ /cm2 or the higher doses, the bacteria does not basically happen photoreactivation phenomenon. Photoreactivation phenomenon in E. coli is more obvious than that in bacteria under the same conditions.
