MONITORING CONTROL DEVICE, WATER TREATMENT SYSTEM INCLUDING SAME, AND WATER TREATMENT METHOD

摘要

A water treatment system includes a water treatment facility which includes a sulfate ion removing unit removing sulfate ions of treatment object water introduced from an inflow pipe and including an oil component and supplying treatment water after removing the sulfate ions to an outflow pipe and a bypass pipe branching off from the inflow pipe and causing the treatment object water to circulate through the outflow pipe, and a monitoring control device which includes a monitoring unit measuring a sulfate ion concentration of the treatment object water including the oil component and a flow rate control unit calculating a supply flow rate of the treatment object water to the sulfate ion removing unit and a supply flow rate of the treatment object water to the bypass pipe, on the basis of the sulfate ion concentration obtained by the monitoring unit.

1. A water treatment system comprising:
a water treatment facility which includes a sulfate ion removing unit removing sulfate ions of treatment object water introduced from an inflow pipe and including at least an oil component and supplying treatment water after removing the sulfate ions to an outflow pipe and a bypass pipe branching off from the inflow pipe and causing the treatment object water including the oil component to circulate through the outflow pipe; and a monitoring control device which includes a monitoring unit measuring a sulfate ion concentration of the treatment object water including the oil component and/or a sulfate ion concentration of the treatment water circulating through the outflow pipe and a flow rate control unit controlling a supply flow rate of the treatment object water to the sulfate ion removing unit and a supply flow rate of the treatment object water to the bypass pipe, wherein the flow rate control unit calculates the supply flow rate of the treatment object water to the sulfate ion removing unit and the supply flow rate of the treatment object water to the bypass pipe, on the basis of the sulfate ion concentration obtained by the monitoring unit.
