【摘要】 研究了超滤+反渗透(UF+RO)新工艺在含钚低水平放射性废水处理中的应用,膜分离系统采用中空纤维式超滤和卷式反渗透联合组件。实验探索了不同工艺参数对废水处理的去污效率和体积减容倍数的影响,结果表明,作为新型膜分离系统,在料液pH=10时其去污效率达到99.94%,体积减容倍数达到12.5,为放射性废水的体积最小化提供了新的处理工艺。更多还原

【Abstract】 Ultrafiltration and reverse osmosis were employed for the treatment of low level radioactive water containing plutonium.The system consists of ultrafiltration module with hollow fibre membrane and reverse osmosis module with spiral membrane.The decontamination efficiency and volume concentration ratio affected by technical parameters were explored in the experiment.The results show that the decontamination efficiency achieves 99.94% and the volume concentration ratio achieves 12.5 at pH=10 for solution fed into the membrane separation system.This technology will be applied in radioactive waste minimization as a new treatment method.更多还原
