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

摘要

A water treatment system includes a water treatment facility which has a coagulation treatment unit injecting a coagulant into water to be treated including oil components and performing coagulation treatment and a monitoring control device which has an oil water separating unit introducing a part of the supernatant water after the coagulation treatment by the coagulation treatment unit and separating the oil components and a deposition tank depositing soluble components dissolved in the supernatant water after separating the oil water. The monitoring control device has a control unit which controls an injection rate of the coagulant, on the basis of at least a deposition amount of the soluble components by the deposition tank.
