| 摘 要： | Both O3 and ClO2 have a high effect on inactivating-algae in source water with no forming THMs which do harm to human in producing drinking water, so they will be favorably substituted for Cl2. In order to make certain of the mechanism of inactivating algae with O3 and ClO2, the algal cell number change and its different characteristics of figures and structures in treated and untreated water have been studied by the microscopy and SEM and the mode of inactivating algae has been inferred. The results show that the mechanism of inactivating algae by O3 is not completely identical with that by ClO2. The actual reaction process and efficiency have been controlled by many factors, such as the different characteristics of oxidants and algal cells.

| Abstract: | Both O3 and ClO2 have a high effect on inacti-vating-algae in source water with no forming THMs which do harm to human in producing drinking water, so they will be favorably substituted for Cl2. In order to make certain of the mechanism of inactivating algae with O3 and ClO2, the algal cell number change and its different characteristics of figures and structures in treated and untreated water have been studied by the microscopy and SEM and the mode of inactivating algae has been inferred. The results show that the mechanism of inactivating algae by 03 is not completely identical with that by ClO2. The actual reaction process and efficiency have been controlled by many factors, such as the different characteristics of oxidants and algal cells. |
