<p>PROBLEM TO BE SOLVED: To provide a method for preventing treated water from becoming whitely turbid due to dissolved sulfide, whose method is required to efficiently prevent the treated water, that is purified in a waste water treatment plant and discharged therefrom, from becoming whitely turbid at a discharge destination and to provide a water treatment method using the method for preventing treated water from becoming whitely turbid due to dissolved sulfide.SOLUTION: The method for preventing treated water from becoming whitely turbid due to dissolved sulfide comprises a step of adjusting the amount of a white turbidity preventing agent to be added to the water to be treated on the basis of such a turbidity detection result that the turbidity of the water to be treated is detected by using a white turbidity detecting agent and/or such an oxidation-reduction potential measurement result that the oxidation-reduction potential of the water to be treated is measured.</p> |
