Recovery method for organic acid, and production method for recycled pulp |
| abstract |
The purpose of the present disclosure is to provide a recovery method for an organic acid. The recovery method makes it possible to efficiently recover an organic acid that is included in a deactivating aqueous solution that includes excrement. This recovery method has the following features. A method for recovering an organic acid that deactivates a highly water-absorbent polymer that is included in used absorbent articles, the method being characterized by including: a deactivation step (S 1 ) in which the highly water-absorbent polymer is immersed in a deactivating aqueous solution that includes an organic acid and has a prescribed pH and the highly water-absorbent polymer is deactivated; a highly water-absorbent polymer removal step (S 2 ) in which the deactivated highly water-absorbent polymer is removed from the deactivating aqueous solution; a pH adjustment step (S 3 ) in which the deactivating aqueous solution is adjusted to a prescribed pH; a concentration step (S 4 ) in which the deactivation step (S 1 ), the highly water-absorbent polymer removal step (S 2 ), and the pH adjustment step (S 3 ) are repeated using deactivating aqueous solution that has gone through the pH adjustment step (S 3 ) and the organic acid in the deactivating aqueous solution is concentrated; and an organic acid recovery step (S 6 ) in which the organic acid is recovered from the deactivating aqueous solution. |
