METHOD FOR PROCESSING LIQUID RADIOACTIVE WASTES Russian patent published in 2018 - IPC G21F9/06 

FIELD: environmental protection.

SUBSTANCE: invention relates to the field of environmental protection from radioactive contamination. Method for processing liquid radioactive wastes includes filtering the waste stream, waste treating with ozone, separating an oxidized stream into a thickened sludge and a liquid phase by filtration, a membrane microfiltration with separation from the liquid phase of radionuclides in the connected form, after purification of the liquid phase on selective sorbents, oxidation before waste treatment by ozone by the introduction of hydrogen peroxide, pH adjustment to provide optimum oxidation conditions at each oxidation stage. After carrying out the oxidation of the solution at the first stage, the oxidized solution is sorbed and filtered on an intermediate filter and gave to the second oxidation stage by ozonation.

EFFECT: invention makes it possible to increase the reliability of the method and simplify the technological design of the process.
