| 摘 要： | 采用纳滤对含Cu^2＋废水进行试验研究，讨论了初始浓度、操作压力、运行时间、阴离子种类、浓差极化对处理效果的影响。试验结果表明NF90膜对含Cu^2＋废水有良好的处理效果，在试验的进水浓度范围内，Cu^2＋去除率超过了98％，出水Cu^2＋浓度低于2．0mg／L，达到中国（GB8978—1996）总铜排放低于2．0mg／L的标准，可以达标排放；随着废液体积的浓缩，铜离子浓缩可达十倍以上，可回用于镀件漂洗，从而实现铜金属的再生利用。与传统的化学沉淀法处理工艺相比，纳滤一次投资大，但由于其运行费用低，具有明显的环境优势和经济效益，值得在重金属废水处理中推广应用。

| Abstract: | The experiments on cupric wastewater were conducted.The effects of the initial copper concentration,pressure,concentration polarization and different anions on the performance of nanofiltration membranes were investigated.The experimental results showed that the removal efficiency of cupric was higher than 98% and its concentrations in permeation liquid were lower than 2.0 mg/L,meeting the Discharge Standard(GB8978-1996)or using as water for washing electroplated products,which verified that nanofiltration ... |
