To provide a water treatment control system which uses a fluorescence analyzer and can reduce the trihalomethane formation capability by measuring the relative fluorescence intensity of raw water to be treated.
A fluorescence analyzer 7 for measuring the relative fluorescence intensity of raw water is connected to the upstream side of a reception well 1 through a raw water sampling hole 5 and is connected to an active carbon injection ratio operation apparatus 8 for obtaining the minimum necessary active carbon injection ratio for reducing trihalomethane formation capability based upon measured values sent from the analyzer 7. The active carbon injection ratio operation apparatus 8 is connected to an active carbon injection control apparatus 9. The relative fluorescence intensity of raw water is measured all the time, and the measured value (FLO) is output to the active carbon injection ratio operating apparatus 8. In the injection ratio operation apparatus 8, the active carbon injection ratio and a target relative fluorescence intensity (FL) corresponding to the control target value of trihalomethane formation capability are set, and the necessary active carbon injection ratio (X) is obtained based on the FLO and FL.
