| 摘 要： | 以电镀漂洗水为主要来源的低浓度重金属废水,多为对生态环境危害极大,难以处理的一类污染物,其彻底处理方法是实现电镀工艺的闭路循环与零排放。针对这一研究目标,讨论了通常用于纯水制备的电去离子(EDI)装置内部构造的适应性改进,并利用自制EDI膜堆对低浓度含镍废水处理进行了实验研究。实验条件下,对于Ni2+含量为40mg/L,pH为5。7的原水,EDI淡化水的Ni2+浓度低于0.1mg/L,浓缩水浓度则达到1060mg/L。研究表明,利用EDI技术处理低浓度重金属废水,可同时实现出水纯化和重金属离子的有效浓缩,回收有价金属和纯水资源,实现重金属废水的零排放与资源化。

| Abstract: | Dilute heavy metal wastewater mostly from rinsing procedure in electroplating,is one of the chief pollutants to environment difficult for treatment. Closed-circuit circulation and zero emission are effective to pollution control. Configuration alteration of electrodeionization(EDI)process commonly for pure water production was discussed,based on which a novel EDI membrane stack was prepared,and the ability of EDI to recover purified water and nickel from dilute nickel wastewater was evaluated. With the feed... |
