The study conducted research on the following four fields : firstly , the characteristics of the interfacial polymerization system of piperazine aqueous solution / trimesoyl hexane solution were systematically investigated . the results show that at a certain molar ratio between the two monomers , piperazine and trimesoyl , at the two phase interface , a dense functional layer of ultra low pressure , high permeating flux and high salt rejection formed by controlling the time of interfacial polymerization , such as the composite membrane ( i ) , the concentration in water phase is 0 . 4 % , and 0 . 1 % in organic phase , and the polymerization time is 1 minute 本文主要进行了四个方面的研究，首先系统分析和研究了哌嗪水溶液均苯三甲酰氯正己烷溶液界面聚合体系特征、界面聚合反应中各影响因素对膜性能的影响等，结果发现，当界面处两相单体(哌嗪和酰氯)分子摩尔比为某一比值时，通过控制界面聚合时间(有机相处理时间) ，可以形成超低压高通量高脱盐的致密功能层，如复合膜( ) ，水相浓度为0 . 4 ，有机相浓度为0 . 1 ，聚合时间1min 。
