摘　　要：采用纳滤技术对模拟含铜废水中铜离子的分离效果进行研究。通过设置单因素控制实验,考察了操作压力、进水铜离子浓度、溶液pH以及不同阴离子对纳滤处理效果的影响。结果表明,对于所配模拟废水,在室温(24℃)条件下,p=0.7 MPa,pH=3,进水铜离子质量浓度为250 mg/L,阴离子为SO_4^(2-)时,铜离子的去除率最高为98.82%。The separation effect of copper ion in simulated copper-containing wastewater by nanofiltration technology was researched. The effects of operation pressure, cooper ion concentration of influent, pH and different anions on treatment efficiency were studied. The results showed that under the optimal conditions with operation pressure of 0.7 MPa, pH value of 3.0, Cu2＋ of 250 mg/L, the removal rate of Cu2＋ could reach up to 98.82% at room temperature（24 ℃）.
