摘　　要：建立了表征系列不同脱盐率的纳滤膜元件运行特性的幂指函数多项式,运用正交设计与数学拟合方法求解了幂指函数多项式的各项系数,图解分析了纳滤膜元件的诸项运行特性,从而系统分析了系列纳滤膜元件的多因素运行特性,为各种不同脱盐率纳滤系统的设计与运行提供了参考依据.An exponential function polynomial to characterize operating characteristics of a series of salt rejection rates of nanofiltration membrane elements is established. The coefficients of exponential function polynomial are solved by using orthogonal design and mathematics fitting. The operating characteristics ofnanofiltration membrane elements are graphically analyzed. The multivariate operating characteristics of a series of nanofiltration membrane elements are systematically analyzed, thus providing a reference for the series of nanofiltration system design and operation.
