WATER TREATMENT DEVICE

摘要

Provided is a water treatment device with which electrode deterioration in an electrostatic-desalination treatment unit can be inhibited to enable the continuation of excellent water treatment performance. A water treatment device (1) includes: an activated carbon treatment unit (10) into which water having a total organic carbon concentration of 100mg/1 or less flows, and which adsorbs and removes organic matter included in the water; and, at a downstream side of the activated carbon treatment unit (10), electrostatic-desalination treatment units (100) which are each provided with a pair of electrodes (101, 102) having voltages of mutually reverse polarity applied thereto, a flow-through passage (105), and ion-exchange membranes (104, 105), and in which ions included in the water are adsorbed onto the electrodes (101, 102) having the voltages applied thereto, and when ions have been adsorbed reverse voltages are applied to the electrodes (101, 102) and ions from the electrodes (101, 102) are eliminated.
