%X The research was focus on the influence of experimental conditions to the removal efficiency of contaminant and the change of biodegradability in the treatment of acrylic fiber polymerization wastewater using three-dimensional electrode reactor with granular activated carbon. The anode was Ti/SnO2-Sb2O3 expanded metal sheet electrode. The cathode was Ti expanded metal sheet electrode. The parameters investigated were the reaction time, electrolytic voltage, initial pH value and aeration amount. The results show that the electrolytic voltage and initial pH value had greater impact on the removal efficiency of organic pollutants. Under the optimal experimental condition with electrolytic voltage 15 V, initial pH value 3, aeration amount 400 mL/min, the removal rates of COD,TOC and acrylonitrile were 32.59%, 22.17% and 89.70%,respectively,and the value of BOD5/COD increased from 0.02 to 0.42 within 120 min,which improved the biodegradability greatly and was beneficial for further biological treatment.
