Membrane fouling control necessitates the establishment of an effective method to assess interfacial interactions between foulants and rough surface membrane. This study proposed a new method which includes a rigorous mathematical equation for modeling membrane surface morphology, and combination of surface element integration (SEI) method and the composite Simpson's approach for assessment of interfacial interactions. The new method provides a complete solution to quantitatively calculate interfacial interactions between foulants and rough surface membrane. Application of this method in a membrane bioreactor (MBR) showed that, high calculation accuracy could be achieved by setting high segment number, and moreover, the strength of three energy components and energy barrier was remarkably impaired by the existence of roughness on the membrane surface, indicating that membrane surface morphology exerted profound effects on membrane fouling in the MBR. Good agreement between calculation prediction and fouling phenomena was found, suggesting the feasibility of this method.
膜污染控制需要建立一种有效的方法来评估污染物与粗糙表面膜之间的界面相互作用。本研究提出了一种新的方法，该方法包括一个用于模拟膜表面形态的严格数学方程，以及表面元积分（SEI）方法和复合辛普森方法的组合，用于评估界面相互作用。新方法为定量计算污染物与粗糙表面膜之间的界面相互作用提供了完整的解决方案。该方法在膜生物反应器（MBR）中的应用表明，通过设置高段数可以实现高精度的计算，此外，粗糙度的存在显著削弱了膜表面上三种能量分量和能量势垒的强度，表明膜表面形态对 MBR 中的膜污染有深远的影响。计算预测与污染现象之间存在良好的一致性，表明了该方法的可行性。
