| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a waste water treatment method for highly treating pulp waste water using monopersulfuric acid and further reducing TOC using waste ozone generated by ozone bleaching treatment.SOLUTION: In a waste water treatment method, monopersulfuric acid prepared by mixing sulfuric acid and hydrogen peroxide is directly added to pulp waste water without being cooled and waste ozone gas generated by ozone bleaching treatment is preferably passed through the pulp waste water at the time of addition of the monopersulfuric acid to adjust the pH of the pulp waste water to 3 or below. |
