反渗透膜污染及其清洗的研究

Study on the Fouling and Cleaning of Reverse Osmosis Membrane

反渗透膜分离技术在水处理中的应用越来越广泛,膜污染也日益受到重视。就常见的膜污染情况进行研究,针对不同的污染情况提出了几种常用的清洗方式,并比较了几种清洗方式的优劣,重点揭示了化学清洗机理,为反渗透膜的清洗提供建议。

Reverse osmosis （RO） membrane separation technology is used more and more widely in water treatment, and much attention has been paid to the fouling of the RO membrane. The common cases of RO membrane fouling are discussed in this paper, and some widely used membrane cleaning methods suit for disparate cases are put forward and compared. The mechanism of chemical cleaning of RO membranes are discussed, and some suggestions for RO membrane cleaning are presented.
