PROBLEM TO BE SOLVED: To materialize water treatment with impurity ion demineralization/purification load, ammonia consumption, and heat loss reduced, by removing impurities contained in treated water through electric demineralization treatment at a high temperature while holding and reusing most of inlet chemical of high concentration contained in the treated water, thus allowing efficient operation of a nuclear power plant. SOLUTION: In this water treatment device, the treated water containing ozonic gas is introduced into at least one reaction vessel 7 to oxidize at least one of contained component of the treated water in the reaction vessel 7. This treatment device includes a pressurizing vortex flow pump 3 for sucking ozone generated in an ozone generator 2 and the treated water to send them out to the reaction vessel, a pressure regulating member 6 provided below the reaction vessel 7, and a pressurizing pipe 4 provided between the flow pump 3 and the regulating member 6 for pressurizing the treated water containing the ozonic gas.
