膜分离,顾名思义,是指利用薄膜进行各种精密过滤、透析,从而达到气-固,液-固两相分离乃至胶体、溶液中溶质和溶剂分离的目的。自四、五十年代起步以来,膜分离技术不断得到充实和发展,至今已成为化学工程学的 Membrane separation, as the name suggests, refers to the use of thin-film precision filtration, dialysis, so as to achieve gas-solid, liquid - solid two-phase separation and even the colloidal solution solute and solvent separation purposes. Since the beginning of the fourth and fifties, membrane separation technology has been continuously enriched and developed, has become a chemical engineering
