(Shanghai Institute of Nuclear Research,Academia Sinica)

Abstract

The UF,RO and Ed combined technological process was used to treat the low-level radioactive waste water coming from the radiochemistry laboratory 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 3.2×103.The results of the low-level radioactive waste water.
