摘　　要：为处理低浓度重金属离子废水,对常规的用于超纯水生产的EDI内部构造进行了适应性改进.以模拟的低浓度含镍废水为研究对象,研究了填充树脂类型对过程分离性能的影响.结果表明,使用大孔型强酸强碱性混床树脂较凝胶型树脂能有效强化过程传质.Applicable configuration alteration of the electrodeionization （EDI） process commonly for pure water production was carried out to treat dilute heavy metal ions waste water. The influence of resins type packing in dilute compartments on performance of the improved EDI technology for simulated dilute heavy metal ions waste water treatment was discussed. It is indicated that packing macroporous type strongly acidic, strongly basic mixed bed resins in dilute compartments of EDI device is one of effective paths for accelerating mass transfer during dilute heavy metal ions waste water treatment by improved EDI technology for specific separation.
