Treatment of Textile Dye Wastewater by Electrocoagulation Method

Abstract:

Article Preview

Electrocoagulation method for textile dye wastewater treatment was investigated in this study. Results show that electrocoagulation can be used powerfully and effectively in organic matter degradation of textile industrial wastewater, where the extent of COD removal and decolorization are achieved about 75.45% and 84.62% after 25 minutes, respectively. pH for textile dye wastewater ascended higher than that of raw wastewater and temperature increased with electrolysis time. GC-MS spectra suggest that organic pollutants in textile dye wastewater are effectively oxidized and decomposed by direct current electrolysis. In addition, the quality of the upper layer liquid after electrolysis nearly meets the criteria of Discharge Standard of Water Pollutants for Dyeing and Finishing of Textile Industry (GB4287-92) of China.
