通过量纲分析建立电超滤—溶析结晶过程中膜通量变化的仿真模型,根据实验数据对模型的相应参数进行回归求解,获得该过程的控制模型.研究结果表明,利用量纲分析法仿真复杂的膜分离过程是简便有效的,基于仿真模型无因交次群的组合设计相应的实验可使控制模型达到较高的预测精度. Through the dimensional analysis, the electrokinetic ultrafiltration-membrane flux change simulation model was established, and the corresponding parameters of the model were obtained by regression analysis based on the experimental data, and the control model was obtained.The results show that the model is validated by dimensional analysis Simulation of complex membrane separation process is simple and effective. Based on the simulation model, the design of the corresponding experiment can make the control model reach a higher prediction accuracy.
