Abstract

This study was to investigate the Sonoelectro-activated persulfate oxidation process for petrochemical wastewater treatment. The effects of Sonoelectro-activated persulfate, electro-activated persulfate, Sono-activated persulfate, persulfate, and ultrasound processes for COD removal were determined. The results reveal that the maximum removal efficiency was obtained at pH = 3, ultrasonic power of 300 W, ultrasonic frequency of 130 kHz, potential electrode of 10 V and persulfate concentration of 20 mM. It was observed that the effective removal of COD was 82.31% for the combined system (Sonoelectro-persulfate), 68.97% for electro-persulfate, 21.11% for Sono-persulfate, 13.06% for persulfate and 2.6% for the single ultrasound system, respectively. The highest removal efficiency obtained at 333 K that was 91.2% after 120 min. In addition, the reaction kinetics of COD removal through Sonoelectro-persulfate process fitted well for pseudo-second-order kinetic model with the regression coefficient of 0.89. According to the results, Sonoelectro-activated persulfate oxidation process has been considered as an effective and efficient technique for petrochemical wastewater treatment. © 2019
