| Abstract: | A type reactor with on-line O3 was used to do further research of the disinfection of total bacteria, E. coli and degradation of 2,4-DCP. The result was obtained in the following conditions. Only UV-radiation, O3 applied by other machine and by the reactor itself, and other conditions were changed to study the disinfection and degradation. The result showed the satisfied effect of disinfection and degradation would be achieved by using UV/O3 applied outside and when the flow rate was about 400 L.h-1, on-line O3 could be produced and make high efforts to enhance disinfection and degradation. The method of UV/O3 was a promising technology in the treatment of drinking water. |
