PROBLEM TO BE SOLVED: To provide a new water treatment device easily and effectively sterilizing water to be treated stored in a water tank. SOLUTION: A cooler (a cooling means) Rf for preliminarily cooling water to be treated by allowing an electric current to flow to an electrode set consisting of electrode plates 110, etc., to perform sterilization by an electrochemical reaction, is disposed in a water treating path 10 for allowing the water to be treated to flow which is connected to the water tank 2. Lowering of the efficiency of a sterilizing treatment is prevented by cooling the water to be treated by using the cooler Rf when water temperature is raised and hypochlorous acid or its ion is easy to vaporize as chlorine gas. |
