| 摘 要： | 本文用复合纳滤膜对印染厂提供印染废水进行了色度和COD的去除试验研究。试验结果表明，纳滤膜技术可有效去除印染废水中的色度和COD，即使对废水的处理率高达90%（过程回收率高达90%）时，膜对印染废水中的COD的去除率仍高达98%以上、对色度的去除率则仍几乎为100%。膜的水通量随着进料流量、操作压力的增大而增大，随着过程回收率的提高而下降。

| Abstract: | The treatment of dyeing wastewater through composite nanofiltration membrane was studied. The results showed that, nanofiltration membrane could effectively reject the COD and colarity of the dyeing wastewater, even at high recovery rate(90%) the rejection of COD and colarity would be larger than 98% and nearly to 100% respectively. The membrane permeate flux increased with the increases of feed flow rate and the operating pressure, and decreased with the rise of recovery rate. |
