Treatment of Imidacloprid Pesticide Wastewater by Microwave-Assisted Catalytic Oxidation

Abstract:

In this study, modified activated carbon used as catalysts treat imidacloprid pesticide wastewater with microwave-assisted catalytic oxidation. The effect of working conditions such as hydrogen peroxide concentration, homogeneous catalysts concentration of Fe2+, amount of activated carbon catalysts, microwave power, irradiation time, wastewater temperature, and pH value on the treatment of imidacloprid pesticide wastewater in the process was investigated. The results show that COD removal rate , can reach 89.25%, with the following working conditions : imidacloprid pesticide wastewater with initial concentration of 268mg/ L , 100 mL ; hydrogen peroxide solution added at a concentration of 26.52g/L , Fe2+ concentration ,109.81mg/L; amount of activated carbon catalysts, 5g;power of microwave , 119 W; irradiation time , 4min ; pH value , 6.
