摘　　要：反渗透膜在使用过程中,常出现易结垢、寿命短、脱盐率低、水通量小等问题。主要针对净水设备用反渗透膜出现的问题进行改性实验研究,通过工艺设计并对其性能影响因素进行分析。通过含浸界面接枝法改性的新型反渗透功能膜通量和脱盐率达到了最佳的平衡状态,亲水性可控。据此方法进行中试后生产的新型反渗透功能膜脱盐率99.52%,水通量大于31.5 L/m^(2)·h,净水产水量3000 L;节水率(净水产水率)57.5%。During the operation of the reverse osmosis membrane,deposit,short life span,low desalination rate and water flux and so on troubles occurence frequently.The preparation process of reverse osmosis membrane was studied,and the influencing factors was analyzed.The flux and desalination rate of the new modified reverse osmosis functional membrane achieved the best equilibrium state.By the immersion interface grafting method,the hydrophilic of membrane was controllable.According to the method,the desalination rate of the new reverse osmosis functional membrane was 99.52%,and the water flux was greater than 31.5 L/m^(2)·h,clean water yield was 3000 L,water saving rate(net aquatic water rate)was 57.5%.
