Abstract

Electrochemical treatment of phenol wastewater was carried out with stainless steel anodes, and phenol removal was achieved through the electropolymerization process. The effects of phenol concentration and bath voltage were discussed. The original chemical oxygen demand (COD) value was approximately 500 mg/L. After electropolymerization treatment, phenol concentration was 0.087 mmol/L with a removal efficiency of 95.6%, and COD was 68 mg/L with a removal efficiency of 86.5%. During treatment, the average current efficiency was 60.36% and power consumption was 27.62 kJ/kg (6.96 kWh/ton). The electropolymerization reaction was analyzed by cyclic voltammetry, and the polyphenol product was analyzed by scanning electron microscopy and infrared spectroscopy.
