Abstract
Petrochemical manufacturing wastewaters often contain a high concentration of biodegradable com-pounds that possess either toxicity or activity inhibition to the biological unit. In this paper, COD removal from Petrochemical wastewaters by electro-Fenton process was studied. The effect of operating conditions such as reaction time, current density, pH, H2O2/Fe2+ molar ratio, and H2O2 of petrochemical wastewater (PW) (ml/l) on the performance of the process has been studied. The experimental results showed that COD was 75.52% removed by the reaction with OH radicals generated from electrochemically assisted Fenton’s reaction. With our cell design, the higher oxidation rate has been obtained applying a current of 57.01 mA, at pH 2.92 and in the presence of 0.3 mM Fe2+ as catalyst and at reaction time of 86.33 minutes.
