The effect of UV disinfection on biological stability in drinking water supply network

摘要

In this paper, the assimilable organic carbon (AOC) and the total number of colonies were determined for studying the effect of Ultraviolet (UV) disinfection of drinking water at Dianliu Pressure Station, Jinan City. The result showed that the total number of colonies on average decreased 28.7% compared with the initial values. However, the value of AOC increased 47.6%, 83.8% and 181.9% after UV disinfection power strengthened. Therefore, the application of UV disinfection of drinking water still need further study to evaluate the disinfection effect.
