Abstract：

Experiment was develpoed to remove Cu2+ from Wastwater and sludge wastwater containning Cu2+ with membrane eletrolysis. When electrolyte in cathode cell was ammonia, NaOH, oxalic acid, Cu2+ removal ratio was 90.1 percent, 50.4 percent, 82peicent for wastewater containning Cu2+; Cu2+ concentration in wastwater was 11.75mg/L,55.4mg/L and 20.92mg/L. When electrolyte in cathode cell was ammonia, NaOH, sodium sulfide, Cu2+ removal ratio was 20.75 percent, 61.06 percent, 40.28 percent for sludge wastewater containning Cu2+. Membrane eletrolysis could achieve Cu2+ removal and recycle from Wastwater and sludge wastwater containning Cu2+, but wastewater quality was impotant influence to its result.
