| 摘 要： | 利用自制的聚酰胺非对称纳滤膜处理水溶性阴离子染料废水,并与NF270商品膜性能进行了比较研究。在0.7 MPa和25℃的条件下,所制纳滤膜对3种阴离子染料的截留率均大于95%。24 h染料连续脱盐运行条件下,膜的水通量保持在50 L.m-2·h-1,染料截留率96%以上,脱盐率稳定在5%以下,具有较好的选择分离性和耐污染性。2种纳滤膜的性能对比研究表明,所制PMIA非对称纳滤膜的染料截留能力和耐高温性优于NF270商品膜,但膜通量稍低。 |

| Abstract: | The aromatic polyamide nanofiltration membrane was evaluated for the treatment of water-soluble dyestuff effluent.Simultaneously,NF270 commercial membrane was used as a reference.It was observed that the rejections of three dyes were all above 95% under 0.7 MPa at 25 ℃.The desalination-purification experiment of dye Direct Blue 71 and NaCl mixed solution showed that the membrane could concentrate DB71 with a high flux(>50L·m-2·h-1),a high dye rejection(>96%) and a salt retention lower than 5%.The dye rejections and high-temperature resistance was better than commercial NF270 membranes,but its membrane flux was slightly lower than that of commercial membranes. |
