| 摘 要： | 本文介绍了TFC?-S型纳滤膜分离电镀镍漂洗水的试验研究,讨论了温度、操作压力、浓差极化、共存离子对膜分离性能的影响。结果表明,这种纳滤膜对电镀镍漂洗水中Ni2 的去除率高于99.5%,透过液中Ni2 质量浓度小于1mg/L;对CODCr的去除率大于96%,透过液中CODCr低于14mg/L,达到国家工业废水排放标准(GB8978-1996),可以直接排放或回用于镀件漂洗。

| Abstract: | The separation of rinse water of nickel electroplating with TFC?-S nano-filtration membrane was studied.The effects of temperature,pressure,concentration polarization and coexisting ions on the separating performance of nano-filtration membrane were investigated.The results showed that the removal efficiency of nickel is higher than 99.5% and with concentration in permeation liquid lower than 1 mg/L;the removal efficiency of CODCr is higher than 96% with CODCr in permeation liquid lower than 14 mg/L.After nano-filtration membrane separation,the rinse water can meets the national integrated wastewater discharge standard(GB8978-1996),and can be discharged directly or used as rinse water again. |
