Abstract
This water treatment device includes: electrode units for performing adsorption/desorption of the impurity; a treatment tank having the electrode units disposed in an inside of the treatment tank; an upstream part for guiding the water into the inside; a downstream part for guiding the water so as to be discharged, the water having been subjected to the adsorption/desorption performed by the electrode units; a circulation pipeline, the circulation pipeline being for guiding water having been guided by the downstream part, to the upstream part; and a switching unit for switching between, on the basis of at least one of a water quality of the water having been guided to the downstream part or an electric state of the treatment tank, guiding the water having been guided by the downstream part, so as to be discharged, and guiding the water to the circulation pipeline.
