WATER TREATMENT SYSTEM

摘要

Provided is a water treatment system which realizes reduction of the environmental load and energy saving. The system includes: an adsorption unit (10) provided with an adsorbent (11) of adsorbing a target in an aqueous solution which is supplied thereto; an separation tank (20) supplied with the target removed from the adsorbent (11) by a medium contacting thereto, water and the medium after contacting, and separating the medium from the mixture of the supplied water, medium and target; a circulation passage connecting the adsorption unit (10) with the separation tank (20), whereby a circulation unit circulates the medium between the adsorption unit (10) and the separation tank (20) via the passage; and an operation control unit 50 controlling a flow of the medium in accordance with a change in an amount of the water removed from the adsorbent (11) and supplied to the separation tank (20).

1. A water treatment system comprising:
an adsorption unit provided with an adsorbent of adsorbing a target in an aqueous solution which is supplied to the adsorption unit; a separation unit supplied with the target removed from the adsorbent via contact with a medium, water and the medium having contacted with the adsorbent, and separating the medium from a mixture of the supplied water, medium and target; a circulation passage connecting the adsorption unit with the separation unit such that a circulation unit circulates the medium to be in contact with the adsorbent between the adsorption unit and the separation unit; and an operation control unit controlling a flow of the medium in accordance with a change in an water amount supplied to the separation unit, wherein the change is caused by the successive contact of the medium with the adsorbent during the circulation thereof in the passage.
