中空纤维更新液膜技术处理含铬废水的实验研究 ? 马竞男 任钟旗 张卫东 杜昌顺 （北京化工大学化工资源有效利用国家重点实验室，北京100029） 摘要：我国冶金、铬盐及电镀工业每年均产生大量的含铬废水，严重危害人体健康，必须严格处理后方 可排放。本文介绍了一种新型的液膜技术——中空纤维更新液膜，概述其传质原理及特点。本文实验研究了 中空纤维更新液膜技术对含铬废水的处理效果，结果表明，中空纤维更新液膜技术对Cr(VI)去除率高，处理 后废水达到国家排放标准，Cr(VI)被浓缩回收，处理过程不产生二次污染。中空纤维更新液膜技术工艺简单， 经济、环境效益高，在含铬废水处理方面具有广阔的应用前景。 关键词：中空纤维更新液膜 铬 废水处理 Studies on Deal with Chromium Laden Wastewater by Hollow Fiber Renewal Liquid Membrane Technology MA Jing-nan, REN Zhong-qi, ZHANG Wei-dong, DU Chang-shun (Resource efficiency using nation emphases laboratory, Beijing University of Chemical Technology, Beijing 100029) Abstract: In our country a great deal of hexavalent chromium laden wastewater from plating, leather-making and chromium-salt industry into environment every year. It is dangerous to our body, must be discharge by strict disposal. This study introduce a new liquid membrane technology—Hollow Fiber Renewal Liquid Membrane technology, and generalize it’s transport theory and characteristic.
