METHOD FOR TREATING BORON-CONTAINING WATER

摘要

PROBLEM TO BE SOLVED: To provide a method for treating boron-containing water by which the amount of chemicals used and the regeneration frequency of an ion exchange resin are reduced and boron can be efficiently removed by flocculation precipitation and/or ion exchange. SOLUTION: (1) In the method for treating boron-containing water by flocculation precipitation, the concentration of boron in the boron-containing water is automatically analyzed and the amount of a flocculant added is automatically controlled. (2) When the boron-containing water is treated by an ion exchange method, the concentration of boron is automatically analyzed and time appropriate to the regeneration of an ion exchange resin is automatically controlled. (3) When the boron-containing water is treated by the ion exchange method after treatment by flocculation precipitation, the concentration of boron is automatically analyzed and the amount of a flocculant added is automatically controlled.
