理论研究方法在膜超(微)滤研究中的应用

在对超(微)滤的过滤性能及过程的研究中，实验研究作出了很多贡献，但实验研究存在着结论对具体实验体系有很大依赖性、研究费用较高等缺点．介绍几种较经典的扩散模型和流体动力学模型及其建模思路、适用范围和存在问题；提出借助理论分析和计算方法设计实验，再根据实验数据利用人工神经网络建立普用性模型的新方法、对于方程的求解，介绍了简化法、摄动法、数值计算与模拟等方法的特点及其在超(微)滤研究中的应用，认为用数值计算的方法研究超(微)滤机理及膜器优化设计必将成为今后超(微)滤研究的重要方向之一．

Application of theoretical method for the study of membrane ultrafiltration and microfiltration

Experimental method plays an important role in studying the performance and processes of ultrafiltration(UF) and microfiltration(MF).But the experiment results depend considerably on the specific experimental condition,and the cost of the experiment is often very high.Some classical diffuse models and hydrokinetics models and the thought of how to modeling,how and where to use it,are recommended in this paper.A new method,using the artificial nerve network to build a wide used model equations,perturbation,numerical calculation method,and their application in the research of UF and MF are discussed.The authors thought that to use the numerical calculation method for probing the mechanism of UF and MF or optimization design of the filter would be one of the most important subjects in the research of UF and MF.
