摘要：

The surfactant wastewater treatment by electro-chemical oxidation with or without peroxide hydrogen was investigated The two anionic surfactants studied here were alkylbenzene sulfonate (ABS) and linear alkylbenzene sulfonate (LAS), both of them being widely used in the household and industrial detergents. Experiments were conducted to examine the effects of pH, electrolyte concentration; time of electrochemical; oxidation, power input and amount of hydrogen peroxide (H2O2) on the surfactant removal and other water quality parameters. Optimum operating conditions were experimentally determined. The enhanced version of eletrochemical oxidation (i.e. with addition of hydrogen peroxide) was found to be Significantly more efficient than that without.
