| 摘 要： | 配制了模拟放射性废水,在＂预处理→反渗透＂系统上将废水含盐量、pH、操作压力和回收率对复合反渗透膜对模拟放射性核素的截留率的影响进行了研究.结果显示：（1）Ni,Mn,Co的截留率随废水水质和操作条件的不同而变化,变化范围分别约为81.8%～98.7%,81.3%～100%,75.9%～98.8%.（2）反渗透是处理含有Ni,Mn,Co废水的有效方法,其中对锰的截留效果优于镍和钴,锰的截留率最高几乎达到100%.

| Abstract: | Simulated radioactive wastewater was confected and treated by reverse osmosis combined with pretreatment to evaluate the impact of wastewater salinity,pH,operating pressure and recovery on simulated radionuclide rejection efficiency of composite reverse osmosis membrane.The results indicated that：（1）The range of rejection efficiency varying with wastewater quality and operating conditions differing were around 81.8%～98.7%,81.3%～100% and 75.9%～98.8% respectively for Ni,Mn and Co.（2）The method of reverse osmosis is effective for purification of wastewaters including Ni,Mn and Co.Compared with Ni and Co,rejection efficiency of Mn was the finest,which could nearly reach up to 100%. |
