实时、在线检测反渗透(RO)膜的污染情况是一个关键问题，但是目前对于这方面的研究较少。概述了利用RTD技术测量 RO膜内流体流动状况的研究进展，重点介绍了卷式 RO 膜 RTD检测系统，利用 LabVIEW软件完成了对 RO膜浓水侧的 RTD响应信号的数据采集、显示和处理，并对新、旧膜进行了相同条件下的检测实验和数据分析。研究结果表明，此方法能够实现 RO膜污染状况的实时、在线诊断，可以广泛应用于反渗透海水淡化工程。

Real-time and on-line detection of reverse osmosis (RO)membrane pollution is a key problem,but few researches was done in this area home and abroad.In this paper,the research of measuring the fluidflow of RO membrane by using RTD is outlined,and the diagnose system of spiral-wound reverse osmosis is introduced,and data acquisition,display and processing of RTD response signal for RO membrane module are completed using LabVIEW software,and detection experiments and data analysis under the same condition of new and old membrane are done.The results showed that this method could realize real-time online diagnosis of RO system and be widely applied to RO seawater desalination proj ects.
