Abstract
The present invention discloses a coagulant for removing or extracting a large amount or volume of organic acid in wastewater at high speed. Means of Solution A water-soluble polymer 6 having an amino group is added into the wastewater containing the organic acid therein, thereby producing an ionic bond 7 built up with the organic acid and the water-soluble polymer 6 having a Pamino group. Next, with addition of a water-soluble polymer 8 having carboxyl group, an ionic bond 9 is built up with the carboxyl group of the water-soluble polymer 8 having carboxyl group and the amino group of water-soluble polymer 6 having an amino group. With this, the organic acid is precipitated as an aggregate 10. The aggregate 10 trapping the organic acid is separated when it passes through a filtering tank.
