摘　　要：本文开发了采用聚砜中空纤维超滤装置改造传统的由海带生产甘露醇的纯化工艺过程。经工业化生产连续一年运行的实际结果表明 ,装置性能稳妥可靠 ,单只膜组件透过液通量稳定保持在5 2 0 L/h以上。包括设备折旧、电费、化学试剂以及劳动力费用在内 ,每生产 1吨甘露醇仅增加成本94.2元 ,且产品质量明显提高 ,显著地提高了产品在国内外市场上的竞争能力。The process of purifying mannital concentrated solution that extracted from the Lawinaria japonica Aresch by the Polysulfone hollow fiber ultrafiltration membranes was reported in this paper. The continuously running results for over a year show that, the performances of the system are reliable. The permeate flux rate for individual element is more than 520L/h. The total cost, including the power chemical reagents, laborangle and the depreciation of equipments, is only about 94.2 yarn per 1000kg monnital. But the quality of mannital has been improved greatly. The technological process, pretreatment way for the feed, determination of the operating parameters of the system, and the cleaning of fouled membrane and recovery of their preferment were introduced in detail.
