摘要
水污染密度指数(SDI)是重要的水质参数,可以有效评价超滤膜预处理效果和反渗透进水水质。结合ASTM标准D4189-07,介绍了SDI的标准测试方法,开展了不同水体系中SDI测试研究,进行了手动和在线自动两种测试方法的比较。结果表明,全自动SDI仪的测试数据准确可靠,精密度高,完全可以满足日常测试水体SDI的要求,为SDI测试提供了新的途径。
Silt density index （SDI） is a critical water quality parameter for evaluating the effect of ultrafiltration membrane pretreatment and the quality of reverse osmosis feed water. Combining with ASTM D4189-07 standard, this article introduced the standard testing method for SDI, carried out research on SDI testing methods of different water bodies and compared the manual method with the automatic method. The experimental results showed that test data obtained from automatic water quality analysis instrument were accurate and reliable with high precision, which fully met the daily requirements of SDI test and provided a new way for the SDI test.
