本文介绍了一种新开发的用于预测膜工艺出水水质的集成均相溶液扩散模型（HSDM）和膜理论模型（FTM）。这些模型考虑了膜压力梯度、渗透压、回收、循环、溶剂传质系数、溶质传质系数和浓度极化作为变量。通过使用单元素和多级试验装置数据，对模型的预测能力进行了比较，以预测实际的全尺寸设施水质。包括6个参考文献、表格、图表。

This paper presents a newly developed integrated homogenous solution diffusionmodel (HSDM) and film theory model (FTM) developed for prediction of waterquality produced from membrane processes. These models consider membrane pressuregradient, osmotic pressure, recovery, recycle, solvent mass transfer coefficient,solute mass transfer coefficient and concentration polarization as variables. Acomparison of the predictive capability of the models was made by using singleelement and multi-stage pilot unit data to predict actual full-scale facilitywater quality. Includes 6 references, tables, figures.
