Summary: | PROBLEM TO BE SOLVED: To reduce heat loss owing to a cooling operation of blowdown water and to suppress consumption of chemicals such as ammonia by reducing load on the desalination of impurity ions by using a desalination unit for selectively removing only impurity ions at high temperature. SOLUTION: In a method for treating ammonia-containing water 12 to be treated by using the desalination unit 11 having a pair of diaphragms 14 and electrodes 17 which are arranged to be opposed to each other on the outside of the pair of diaphragms 14 and between which a DC voltage is applied, the water 12 to be treated is treated at ≥100°C to obtain the treated water from which impurity ion components are removed and in which ammonia is concentrated.
