Abstract: This paper deals with the treatment of dye wastewater by micro-electrolytic reduction-oxidation system.The results showed that the decolorization efficiency were above 97%,and the removal of the efficiency of COD were above 90%.The optimum condition and the mechanism of the treatment were also discussed.The compounds in wastewater were identified and characterized by GC/MS and UV-vis spectra.

Key words: micro-electrolytic reduction-oxidation, cyanine dye, wastewater treatment
