| 摘要:膜分离技术具有分离效率高、易控制、无污染等优点，成为水处理技术的首要选择。商品有机膜主要为聚砜类、聚偏氟乙烯类合成高分子膜和再生纤维素及其衍生物类天然高分子膜。本文在对不同分离膜的优缺点及应用领域概述的基础上，对再生纤维素微滤膜、超滤膜和纳滤膜的制备、化学改性及应用现状进行了综述，进而阐述了分离性能、力学性能及抗污染性能对再生纤维素膜在水处理中的影响与研究进展。 |
| Abstract:Membrane separation technology has become the primary choice of water treatment technology due to the advantages of high separation efficiency， easy control， and no pollution. Commercial organic membranes mainly are synthetic polymer membranes based on polysulfides and polyvinylidene fluorides and natural polymer membranes based on regenerated cellulose and its derivatives. Then， the characteristics of different separation membranes and their application fields were introduced. In addition， the preparation， modification and current situation of regenerated cellulose microfiltration membranes， ultrafiltration membranes， and nanofiltration membranes were reviewed respectively based on the summery of advantages and disadvantages of different membrane and application. Subsequently， the effect and research progress of separation performance， mechanical performance and anti-pollution performance on regenerated cellulose membranes in water treatment were further described. |
