New technology for the treatment of wastewater containing orgainic pollutant-micellar-enhanced ultrafiltration

胶团强化超滤是一种处理含有机污染物废水的新技术。该技术利用表面活性剂胶团对有机物的增溶作用,结合超滤工艺,进而达到去除有机污染物的目的。文章详细介绍了胶团强化超滤处理含有机污染物废水的原理、影响因素,分析了该技术目前存在的问题以及今后的发展方向。

Micellar-enhanced ultrafiltration(MEUF) is a new technology for the treatment of wastewater containing organic pollutant. The basic idea is that the surfactant forms micellae when it is added to aqueous streams with a concentration higher than its critical micellae concentration. Almost all of the organism originally dissolved can be solubilized in the micellae formed by the surfactant. Solution then passes through an ultrafiltration membrane with pores small enough to block micellae passage. So as to achieve the goal of getting rid of the organic pollutant. The principle and influence factor of micellar-enhanced ultrafiltration are introduced in detail, and the problems existing in this technology and its developing direction in the future are analysed.
