系列纳滤膜元件动态特性的回归分析

The Regression Analysis of Dynamic Characteristic for Series Nanofiltration Membrane Elements

明确了纳滤膜元件运行特性与动态特性的概念,给出了膜系统运行状态方程及膜元件动态特性表达式的求解方法,并说明了纳滤膜元件脱盐率特性曲线的变化规律,为纳滤膜系统软件的设计及运行分析提供了数据基础.

The concepts of operation and dynamic characteristics of the nanofiltration membrane elements are clarified. Meanwhile, the solving methods of operation state equation of membrane system and dynamic characteristic expression of membrane element are also given in this paper. Besides, the authors illustrate the change rules of desalination rate level char- acteristic curve of nanofiltration membrane element, which provides data basis for the software design and operation analysis of nanofiltration membrane system.
