Biofilm Electrode Method for Degradation of P-Nitrophenol

Junsheng Hu, Huan Wang, and Zhenxin Zhang
Abstract—With p-nitrophenol as the target contaminant, the influence of various factors: aeration rate, electrolyte concentration, and initial pH to chemical oxygen demand (COD) and p-nitrophenol (PNP) removal efficiency of the wastewater containing nitro phenol were studied in experiments with the homemade biofilm electrodes reactor. Research shows that with the increasing of aeration rate, electrolyte concentration, or initial pH, COD and PNP removal efficiency of the wastewater showed a decreasing trend after the first increase. The best experimental conditions of nitrophenol degradation adopted biological membrane electrode method, under the conditions of electrolysis time of 4h, impressed voltage of 6V and initial concentration of 200 mg/L, is aeration rate of 0.2 m3/h, electrolyte concentration of 1.0 g/L and initial pH of 7. Under the best conditions, the PNP nitrophenol wastewater removal efficiency was 85.85%.

Index Terms—Biofilm electrode, chemical oxygen demand, electrochemical oxidation, p-nitrophenol.
