Through comparison and analysis of various current sterilizing techniques, this paper puts forward some methods for treating secondarily polluted water, and explains by using actual engineering examples the rationalization of treating secondarily polluted water with chlorine dioxide and ultraviolet sterilizing techniques.

In this paper, the disinfection combination technique of UV+TCCA was applied to a dual tube drinking water supply engineering to disinfect the drinking water.
