摘　　要：苦咸水反渗透(BWRO)中的防垢过程,首先取决于给水水质,而根据水质条件和垢在膜面的形成机理采取相应的防垢措施是非常重要的。显然,有效地管控膜面无机结垢及抑制膜面污染需要开展无机结垢趋势的预测、防垢措施和非破坏性无机垢监控等方面的技术研究。一系列传统和新兴的分析技术,包括摩尔比率法、直接目测法和光谱法等已应用于BWRO过程中膜面防垢研究。本文详细综述了该过程中无机结垢趋势的预测、防垢方法和非破坏性无机垢监控技术等方面的研究进展。此外,针对目前的研究方向提出了建议。It is very important to take appropriate inhibiting scaling measurements in brackish water reverse osmosis（BWRO） desalination process, which depends on feed water characteristics and scaling formation mechanism on membrane surface. Managing scale formation relies on early scaling potential prediction, judicious system design, influent pretreatment and non-destructive detection. A range of conventional and emerging analytical techniques, including molar ratio, direct observation and spectroscopic methods have evolved to predict scale potential and detect scale formation in real time. This review considers the prediction of scaling tendency, scale control techniques and non-destructive scale monitoring techniques based scales that are encountered when reverse osmosis is used in brackish water desalination applications. These techniques can significantly inhibit membrane surface scaling and decrease membrane fouling. Moreover, the suggestions are also presented in this field.
