摘要
以α－淀粉酶水解淀粉反应与超滤膜分离一体化为研究体系，进行了超滤膜的分离特性实验及其膜通量衰减程度的测试，从中选出透过通量高、截留率高、不易污染、易于清洗且满足该酶膜反应要求的超滤膜，如ＰＳ／ＰＤＣ，６０００；ＰＳ／ＰＥＳ，６０００；ＰＥＳ，１００００和ＰＳ，２００００等。研究表明，只有通过选膜实验，方能找到符合分离要求的膜，这是除所用的酶必须有一定的酶活力和稳定性外。
Based on the prerequisite for integration of starch hydrolysis by α amylase and ultrafiltration separation,some experiments about separation efficiency of various ultrafiltration membranes were done,from which high permeate flux,high rejection effect,not easy fouling and easy washing membranes such as PS/PDC,6000;PS/PES,6000;PES,10000 and PS,20000 were selected.It is found that experimental selection of membrane isnecessary for obtaining a suitable ultrafiltration membrane,which is another prerequisite for integration of emzymolysis and memebrane separation else than enzyme having certain activity and stability.
