Abstract:
A water treatment control system using a fluorescence analyzer comprising:an injection mechanism for injecting an impregnating agent to a water to be treated; a fluorescence analyzer for measuring a relative fluorescence intensity of the water to be treated; a flowing water flowmeter for measuring a flow rate of the water to be treated; and a control apparatus for calculating an impregnating agent injection rate necessary to reduce a trihalomethane formation potential based on a measured value from the fluorescence analyzer to control the injection mechanism based on the impregnating agent injection rate and the flow rate from the flowing water flowmeter, wherein the injection mechanism includes an activated carbon injector for injecting an activated carbon to the water to be treated, and wherein the control apparatus includes an activated carbon injection rate calculating apparatus for calculating an activated carbon injection rate necessary to reduce the trihalomethane formation potential based on the measured value from the fluorescence analyzer, and an activated carbon injection amount control apparatus for controlling an activated carbon injection amount from the activated carbon injector based on the flow rate from the flowing water flowmeter and the activated carbon injection rate calculated by the activated carbon injection rate calculating apparatus.
