Abstract

　

The electro-oxidation treatment of textile wastewater containing azo or disperse dyes was investigated. The electrochemical decomposition was performed in two divided cell reactors, each with anode and cathode compartments, using a porous carbon anode.　Indirect oxidation by means of chlorine-deriving compounds was the predominating process.　In the electrochemical treatment, the BOD of the dye solution increased, and a reduction in the molecular weight distribution was identified by LC-MS analysis.　After 6hr of anodic electrolysis and 24hr of biological treatments, the color of wastewater from the textile factory was effectively reduced.
