PROBLEM TO BE SOLVED: To provide a disinfection control system for clean water that can supply safe clean water to water supply terminals by maintaining the disinfection ability of a disinfectant in the clean water even in an environment where corrosion occurs inside a pipe line in a pipe network for supplying clean water and recontamination from the outside occurs in accordance with breakage of the pipe line.SOLUTION: A disinfection control system for clean water, which supplies a disinfectant to clean water, uses a first disinfectant exhibiting a disinfection effect immediately after injection and a second disinfectant exhibiting a disinfection effect at a time later than that of the first disinfectant, and comprises first disinfection means for injecting the first disinfectant, second disinfection means for injecting the second disinfectant after the first disinfection means, and control means for calculating the concentrations of the first and second disinfectants at predetermined faucets and determining, based on the calculated concentrations, the amounts of the disinfectants injected by the first and second disinfection means.SELECTED DRAWING: Figure 2 |
