METHOD AND SYSTEM FOR TREATING ORGANIC MATTER-CONTAINING WATER

摘要

PROBLEM TO BE SOLVED: To provide a method and a system for treating organic matter-containing water, in each of which an excellent COD reducing effect can be obtained at a low cost.SOLUTION: The method for treating organic matter-containing water comprises the steps of: biologically treating the organic matter-containing water and performing membrane treatment on the biologically-treated organic matter-containing water by using a separation membrane; adding a liquid or solid oxidizer to the permeated water separated from the separation membrane; and making the oxidizer-added permeated water pass through a vessel in which solid particles including a manganese-containing metal-based solid catalyst are packed.
