PURIFICATION OF RADIOACTIVE CONTAMINATION WASTE LIQUID WITH FOAM SEPARATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a purification method of radioactive contamination waste liquid capable of easily removing radioactive material in the radioactive contamination waste liquid.SOLUTION: A purification method of radioactive contamination waste liquid includes the steps of: introducing bubble into radioactive contamination waste liquid j added with a surface active agent to generate foam; concentrating radioactive material into a gas/liquid interface area together with the surface active agent; and removing the radioactive material together with the surface active agent.SELECTED DRAWING: Figure 1
