Application and optimization of electro-Fenton technology in advanced treatment of petrochemical industry wastewater

Abstract

Within this research endeavor, a refined electric-Fenton remediation protocol was put forth for the enhanced reconditioning of intensely polluted organic effluents originating from the petrochemical sector. Using DSA (Dimensionally Stable Anode) electrode material and ultraviolet (UV) catalysis, the wastewater treatment efficiency and the ability to degrade refractory organic compounds were significantly improved. By optimizing the reaction parameters, the mineralization speed and treatment efficiency of organic matter are significantly improved, the use of H2O2 is reduced, and the cost of chemicals and energy consumption are reduced. At the same time, the technology avoids the use of a large number of harmful chemicals and mitigates the peril of subsequent contamination, thus rendering it appropriate for a spectrum of petrochemical effluents. Moreover, it exhibits efficacious abatement on diverse categories of organic contaminants.
