摘要

在直流条件下，根据离子在外加电场上发生电迁移的特性，以NaCl分离实验数据为基础，建立了电渗析海水淡化的数学模型。数学建模从稳态质量平衡微分方程出发，推导出方程，并通过实验进行验证。模型参数由实验数据确定。该模型给出了不同电压、流速和进料浓度下稀释室的浓度。通过对预测数据与实验数据的比较，发现实验数据与计算数据具有较好的一致性，数学模型可以很好地预测工艺过程。

Mathematical Modeling for Desalination by Electrodialysis

Under this condition of direct current (DC), according to the property that ion electromigration happens on the external electric field, mathematical modeling for desalination by electrodialysis (ED) was established on the basis of NaCl separation experimental data. The mathematical modeling started from a differential equation of steady-state mass balance, derived the equation and was validated by experiments. The model parameter was determined by the experiment data. The model gives concentration of dilute compartment for various voltages, flow rates and feed concentrations. According to comparing predicted data with experimental data, it was found that there is a good consistency between the experimental and calculated data and the mathematical modeling could be used to well predict the process.
