Abstract

The electrochemistry method was applied for the treatment of high-salinity dye intermediate wastewater from the process of 3-diethylaminophenol.The results indicate that COD and chroma removal rate can reach 70% and 80% respectively under the optimum electrolysis conditions(electrical current density=0.015 A/cm~2,electrolysis voltage=8.4 V,t=90 min).The primary mechanism of electrochemical reaction was also studied by investing the treatment of dye effluents containing NaCl and Na_2SO_4.
