Abstract
A method and an apparatus for processing radioactive wastewater are provided, wherein the radioactive wastewater is processed by using Disc Tube Reverse Osmosis (DTRO) membrane assembly, thereby achieving both the effects of high decontamination factors and high concentration multiples. In said method, the radioactive wastewater passes through the first-stage membrane assembly and the second-stage membrane assembly in sequence to obtain the second-stage clear water, and the first-stage concentrated water flowing out of the first-stage membrane assembly enters the third-stage membrane assembly to obtain concentrate.
