摘  要:
采用中空纤维膜超滤豆腐废水提取大豆低聚糖,对膜阻力的分布进行了研究。通过测定不同条件下超滤的通透量,计算出超滤过程中各种阻力及其所占的比例。试验结果表明:预处理及超滤条件不同,其过滤阻力构成也不同。预处理愈完善,其浓差极化阻力愈低,总阻力也越小。

摘  要:
The UF membranes of microporous hollow fiber were used to study the distribution of the membrane resistance in the process of extracting soybean oligosacchrides. According to the flux measured under different conditions,the membrane resis- tance of every part and its ratios of the part to total resistance were calculated. The experimental results showed that the different conditions of pretreatment and ultrafiltration would have caused differences of the membrane resistance. Less concentration polarization resistance would be expected for a better pretreatment, and total resistance could decrease correspondingly.
