Post‐Treatment of Coking Industry Wastewater by the Electro‐Fenton Process
Effluents of the coking industry cannot be effectively treated in biological treatment units because of non‐biodegradable organic matters and phenolic compounds present in the wastewater. In this study, post‐treatment of biologically treated coking wastewater via the electro‐Fenton process was investigated to minimize the effects of discharge of this kind of wastewater on the environment. The electro‐Fenton experiments were performed using cast iron electrodes. Chemical oxygen demand (COD) and phenol were selected as the target parameters. The optimum operating conditions were as follows: reaction time = 10 minutes, pH = 3.0, electrical current = 1.0 A, and [H2O2] = 2000 mg/L. Under these conditions, COD and phenol removal efficiencies were 67.8% and 98.0%, respectively. In addition, it was determined that COD removal followed first‐order reaction kinetics. Consequently, the electro‐Fenton process was determined as an effective alternative post‐treatment method for coking industry effluents.
