%X Electrode-SBBR system was used to investigate the effects of various factors on removal of copper ion such as current intensity (IA), competing ions (SO42-, NO3-, Cl- and Zn2+, Pb2+), the initial Cu2+ concentration and pH. Results showed that the removal rate of Cu2+was up to 98% while the IA was 40 mA. However, adding anions(SO42-, NO3-, Cl-) and cations(Zn2+, Pb2+) both increased the concentration of Cu2+ in effluent, and significant increases were observed while Cl- and Pb2+ concentration were 45 mg/L and 30 mg/L, respectively. Additionally, with initial concentration of Cu2+ being 30 mg/L, the highest removal rate of Cu2+ was 98.48%; and concentration of Cu2+ in effluent failed to meet the standard while concentration of Cu2+ of influent exceeded 70 mg/L. Furthermore, the removal process was undermined both under acid (pH 4.0~4.5) and alkaline (pH 9.0~10.0) conditions, while the situation was worse in the former one. Under the condition of pH ranging from 4.5 to 7.5, removal rate of Cu2+ reached 97.78%.
