<P>PROBLEM TO BE SOLVED: To obtain a water treatment device capable of sterilizing by emptying a pathway without discharging water. <P>SOLUTION: A purification unit 4 purifies raw water supplied from a raw water supply unit 2 and passes the result to a purified water supply pathway 3. The device is provided with at least: a reservoir unit 5 that can retain at least the water in the purified water supply pathway 3; a sterilizing fluid generating unit 8 that can generate a sterilizing fluid containing a sterilizing component and supply the result into the purified water supply pathway 3; and a sterilizing component decomposition unit 81 that, at the completion of sterilization, recovers the sterilizing fluid in the purified water supply pathway 3 and decomposes the sterilizing component. Also, during sterilization of the purified water supply pathway 3, the water in the purified water supply pathway 3 is transferred to the reservoir unit 5. This transferred water is used as raw water after sterilization. <P>COPYRIGHT: (C)2013,JPO&INPIT |
