摘　　要：研究了电沉积法处理低浓度酸性含铅工业模拟废水的工艺条件,并对各种影响因素进行了研究和分析。结果表明:电极材料、电解槽的极距、槽压等对电沉积效率及深度净化效果均有较大影响。以泡沫铜为阴极材料的三维电极,在零极距、槽压4 V条件下,Pb2+去除率(回收率)可达85%,明显优于以不锈钢板为阴极的二维电极的34%。The processing conditions of treating industrial simulated acidic lead-containing wastewater with light concentration by electrodeposit method has been studied, and various influencing factors have been investigated and analyzed. The results show that all of electrode material, polarity distance of electrobath, voltage of cell, etc. possess great influence on electrodeposite efficiency and deep elimination of lead ions. Three-dimensional electrode-foam copper is used as cathode, under the conditions of almost zero polarity distance between cathode and anode and 4 V cell voltage,the removing rate （recovery rate） of Pb2＋can reach 85% ,which is much better than the 34% removing rate achieved by two dimensional cathode-stainless steel board.
