摘　　要：淤泥密度指数(SDI)是反渗透法(RO)脱盐系统最重要的进水控制指标之一。但在实际生产中,由于地域区别和历史原因,存在两种测定方法,给实际应用带来不便。研究基于自来水体系对两种SDI测定方法进行对比分析,拟合出关联公式,可显著缩短测定时间,便于实际生产中应用。Silt density index （SDI） is one of the most important indexes of in taking water quantity for reverse osmosis system. Two kinds of determination methods of SDI exhibit different results and do not benefit for practical production due to different region and historical reasons. In this paper two kinds of determination methods of SDI were compared to fit relation equation based on the experiment data on tap water system, it was shorten the test time and convenient for practical application to determine the SDI by his equation

关 键 词：淤泥密度指数(SDI值) 测定方法 拟合
