| description | According to the present invention, a supply pipe 3 for pretreated water W to be subjected to ion exchange is coupled to the upper part of a regenerative ion exchange column 1, whereas a discharge pipe 4 for ion exchange-treated water W1 is coupled to the lower part of the regenerative ion exchange column 1. A pipe 5 and a pipe 6 for respectively supplying a NaOH solution and hydrochloric acid (HCl), which are regeneration drug liquids, are respectively coupled to the supply pipe 3 and the discharge pipe 4. In addition, a discharge pipe 7 for waste water to be regenerated is coupled to a sidesection of a column body 1A. In addition, the discharge pipe 4 has a resistivity meter 8, and a sodium ion electrode 9 for measuring the sodium ion (Na+) concentration of the ion exchange-treated water W1. According to the regenerative ion exchange device, short-term fluctuations can be inhibited in the concentrations of sodium ions (Na+) and chloride ions (Cl-) in treated water in a secondary pure water system (sub-syste |
