Mechanism and Prevention of Membrane Fouling during Electrodialysis of Fermentation Feed
, 2009 发酵工业中产品提取后残液含有丰富的可利用成分和其它水污染物质，实现废液资源化利用是实现清洁生产的关键。电渗析具有过程简单、效率高、废物排放少等特点，可降低物质和能源消耗、减少废物排放、消除环境污染，为某些物质资源的再生和回收、某些酸和碱的分离和制备，实现废液的资源化和清洁生产提供一种新途径，然而膜的污染和劣化却始终是制约电渗析技术工业应用的瓶颈。 本文针对两种发酵料液味精等电母液和赖氨酸离交废液的电渗析过程研究了离子交换膜的污染，观察了污染膜面的形貌，对污染物进行了成分分析，从而确定了污染物质及污染机制，

, 2010 使用三室双极膜电渗析法处理乳酸发酵液时,杂质氨基酸的迁移会影响回收乳酸的纯度.通过对乳酸发酵液电渗析过程中氨基酸迁移现象的研究,发现各种不同氨基酸的迁移速率主要受其初始浓度、pI值与料室pH值的差值、阴离子交换膜对其选择性及其自身电迁移率的影响.根据此规律,建立了离子迁移速率计算模型,通过与实际过程比较,表明其可有效预测杂质氨基酸的迁移情况,估算特定体系达到预定收率时的纯度.实验验证结果表明,氨基酸的迁移率为32.5%,与对照实验(82.6%)相比,降低率为60.7%.通过调节氢渗漏控制料室pH值 ...
