Abstract
PURPOSE: To treat waste water effectively by a method in which the reaction of ozone in waste water to be treated is raised in such a way as to leave hydrogen peroxide in the treated water and then the remaining hydrogen peroxide is decomposed by a chlorine-based oxidizing agent.
CONSTITUTION: Hydrogen peroxide is added to waste water to be treated and the waste water is brought into contact with ozonized gas. The addition of hydrogen peroxide accelerates the reaction of ozone and therefore raises the utilization efficiency of ozone. In this case, the amount of hydrogen peroxide to be added is regulated so as to leave a given concentration of hydrogen peroxide in the treated water, and then a given amount of a chlorine-based oxidizing agent is added to the treated water to decompose the remaining hydrogen peroxide. Thus, hydrogen peroxide remaining in the treated water, which is unavoidable essentially, can be effectively utilized.
