膜技术在废水处理中的应用

Application of Membrane Technology to Wastewater Treatment

着重介绍了膜技术在生活污水、油田采出水、造纸废水、纺织印染废水、高浓度有机废水和重金属废水中的应用。膜技术处理废水与传统的废水处理方法相比具有处理效果好,可实现废水回用和有用物质回收的优点。并展望将膜技术应用于废水处理,特别是近年来新发展起来的纳滤膜分离技术应用于含低分子量污染物的分离,与传统的废水处理过程相结合等技术均将产生较大的社会效益与经济效益。

Application of membrane technology to wastewater treatment were briefly introduced, including treatments of domestic wastewater, oilfield produced water, paper making wastewater, textile and dyeing wastewater, high concentrated organic wastewater and heavy metal wastewater. The membrane technology applied to wastewater treatment compared to the traditional methods can not only achieve better treating efficiency but also reuse and recycle for water. It prospected that application of membrane technology to wastewater treatment, especially application of NF to separate lower molecular weight pollutant from wastewater and the combination with traditional processes for wastewater treatment may bring greater social and economic ben- efits.
