Decolorization method for colored wastewater |
| abstract |
[PROBLEMS] To provide a coloring substance removing technology that can obtain water with a level near colorless without increasing the pollution of drainage water without using a large amount of inorganic metal salt when removing colored substances from colored wastewater. To do. In a method for decolorizing colored wastewater, the method comprising separating a colored portion material from a colored wastewater containing at least a colored material and a polyvalent carboxylic acid or a polyvalent aminocarboxylic acid, First, an inorganic metal salt is allowed to act on a hydrogen ion concentration index (pH) at which at least two carboxyl groups of polyvalent carboxylic acids or polyvalent amino acids are non-dissociated. Decolorization method for colored wastewater. [Selection figure] None |
