Title:
RADIOACTIVE WASTE LIQUID TREATMENT METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/196143
Kind Code:
A1
Abstract:
Disclosed in the present application are a radioactive waste liquid treatment method and apparatus. The method comprises: performing separation on a radioactive waste liquid to obtain a first purified liquid and a concentrated liquid; removing radioactive nuclide from the concentrated liquid to obtain a second purified liquid, wherein removing radioactive nuclide from the concentrated liquid comprises performing a chemical precipitation process on the concentrated liquid; and discharging the first purified liquid and the second purified liquid. The radioactive waste liquid treatment method and apparatus in the present application have a high radioactive waste liquid purification level, and also significantly reduce the yield of radioactive waste, thereby minimizing the radioactive waste.
