摘　　要：明确了反渗透膜元件静态与动态特性的概念,给出了膜系统运行状态方程及膜元件动态特性表达式的求解方法,说明了有机与无机污染前后膜元件特性曲线的变化规律,揭示了系统污染后沿流程各位置膜元件的静态特性变化趋势。The concept of static and dynamic performance of RO membrane elements was defined. The equation of operation state in RO membrane system and the solution for formulation of RO membrane elements dynamic performance were obtained. The variation regularity about the dynamic performance curve of RO membrane elements before and after organics and inorganics contamination was illustrated. The variation trend of RO membrane elements static performance in each position along the contaminated system process was indicated.
