PROBLEM TO BE SOLVED: To provide a method for treating boron-containing waste water, capable of completely reducing the boron concentration in the waste water by generating good flock and conducting sedimentation treatment.SOLUTION: Boron-containing waste water is blended with an aluminum compound, calcium compound and sulphated compound, and the waste water treated in a high pH region is blended with a specific terpolymer and thus good flock is generated, and aggregated and settled as sedimentation with high filterability to remove the boron. |
