Dyeing wastewater was treated by electro-coagulation method. The effects of different electrode material, wastewater pH, current density and reaction time were investigated. The optimum conditions of the electro-coagulation are described as follows:Fe electrode is applied, pH of the wastewater is 10~11, current density is 200 A/m2 and reaction time is 5~8 min, the removal rate of colority and COD are about 98% and 70%, respectively.
