摘要
介绍用超滤—反渗透—电渗析组合工艺处理放射化学实验室排出的低水平放射性废水。叙述了内压管式超滤器、中空纤维反渗透器及电渗析器在废水处理中的脱盐,去污等效果,及两种清洗方法对超滤膜通量恢复的比较等。由“三膜”组合工艺组成的 URE 流程去污因子高达3.2×10~3,为放射性废水的处理提供了一种新的方法。
The UF,RO and ED combined technological process was used to treat the low-level radioactive waste water coming from the radiochemistry labo- ratory in our institute.This paper referred to the percentage of desalination and decontamination and their function in the technological process.And a comparison was made of the cleaning efficiency using the chemical method and the spongeball method.The URE process was found to have a good decontamination efficiency,its D.F.reaching 3.2×10~3.The results of the test show that the URE process has an excenllent ability in treating the low-level radioactive waste water.
