영문 초록

The experiments for the characterization of inactivation were performed in a series of batch processes with the total coliform as a general indicator organism based on chlorine, chlorine dioxide and ozone as disinfectants. The water samples were taken from the outlet of settling basin in a conventional surface water treatment system that is provided with the raw water drawn from the mid-stream of the Han River. The inactivation of total coliform was experimentally ana-lyzed for the dose of disinfectant, contact time, pH, Temperature and DOC. The nearly 2.4, 3.0, 3.9 log inactivation of total coliform killed by injecting I mg/l at 5 minutes for chlorine, chlorine dioxide and ozone. For the inactivation of 99.9%(3 log), Disinfectants required were 1.70, 1.00 and 0.60 mg/l for chlorine, chlorine dioxide and ozone, respec-tively. The higher the pH is, the poorer the disinfections effects are in the range of pH 6-9 by using chlorine and ozone. But the influence of pH value on killing effects of chlorine dioxide is weak. The parameters estimated by the models of Chick-Watson, Horn, and Selleck from our experimental data obtained for chlorine are: log(N/No) = -0.16 CT with n = I, log(N/No) = -0.71 CO.87T with n ≠ 1, for Chicks-Watson model, log (N/No) = -1.87CO.47T0.36 Horn model. For chlorine dioxide are: log(N/No) = -1.53 CT with n = I, log(N/No) = -2.29C0.94T with n ≠ 1, for Chicks-Watson model, log(N/No) = -3.640.43T0.24 for Horn model and for ozone are: log(N/No) = -2.59 CT with n = 1, log(N/No) = -2.82 C0.36T with n ≠ I, for Chicks-Watson model, log(N/No) = -4.53CO.26T0.l9 for Horn model.
