| titleOfInvention | Drainage treatment method and drainage treatment device |
| abstract | The present invention provides a simple drainage treatment method for selectively recovering phosphate ions from wastewater containing ions such as nitrate ions, sulfate ions and iodine ions and phosphate ions.n n n In addition, the present invention is a wastewater treatment method comprising the step of recovering the phosphate ions from the waste water containing at least one selected from the group consisting of nitrate ions, sulfate ions, and iodine ions, and phosphate ions, acidic By contacting the said drainage with an anion exchange resin in the state shown, the ion contained in the said drainage among the nitrate ion, sulfate ion, and iodine ion is ion-exchanged, and then the said drainage is contacted with anion exchange resin again, and said anion exchange is carried out. Provided are a wastewater treatment method and a wastewater treatment apparatus used for the treatment method, wherein the phosphate ions are recovered by ion exchange of the phosphate ions to a resin.n n n n Drainage Treatment, Anion Exchange Resin, Recovery, Phosphate Ion, Device |
