  • Treatment Of Water By Oxidation Or Reduction (AREA)

Abstract

PURPOSE: To enable to carry out the H2O2 added O3 oxidizing treatment in conjunction with the desalting by a method wherein, after acidic anion in water to be treated is removed to adjust the pH to a predetermined value or more by increasing OH-, the O3 oxidizing treatment is carried out in the presence of H2O2.
CONSTITUTION: Water to be treated is passed through an oxidation anion removing portion 8 packed with an OH type anion exchange resin to adjust the pH value to 7 or more by increasing OH-. When said water is sent to an oxidation treating portion 3 and placed under the concerted oxidizing action of a small amount of H2O2 added and supplied from a water storage tank 4 and ozonized air or ozonized oxygen supplied from an O3 generator 5, hardly decomposable org. substanced in water is also decomposed by oxidation to CO2 gas and water. Subsequently, the treated water is sent to an alkaline cation removing portion 9 packed with a H-type cation exchange resin and neutralized by removing alkaline cation and increasing H+ to adjust the pH value of the treated water to a desired range.
