Abstract

Efficiency of the integration process of Fe/C micro-electrolysis and Fenton for the treatment of coal chemical industry wastewater was studied and the operational parameters were optimized. Response surface methodology was employed to investigate the effects of the main factors (pH, Fe/C ratio and H2O2 dosage) on treatment efficiency and optimize the parameters. The interaction of Fe/C ratio and H2O2 dosage exerted significant effect and the interaction of pH and Fe/C ratio showed moderate effect on COD removal. While the interaction of pH and H2O2 dosage had little effect. The optimal pa-rameters were determined as pH 3.88, 1.04 of Fe/C ratio and 60.25 mg/L of H2O2 dosage, with the predicted optimal COD removal efficiency of 87.27%. The up-flow reactor exhibited high treatment performance and stabilization. The current work could provide scientific and theoretical bases for the treatment of coal chemical industry wastewater and the integration of Fe/C microelectrolysis and Fenton.
