| titleOfInvention | Method of processing radioactive sewage from laundries at nuclear plants |
| abstract | The invention relates to the treatment of liquid radioactive waste, and more specifically to the treatment of waste p. using flocculation methods. C. G. The invention is to increase the safety of the environment by ensuring the cleaning of radioactive waste from radionuclides. phosphates, surfactants, as well as toxic components of radionuclide precipitants. This goal is achieved by two-step precipitation, including, at the 1st stage, adjusting the pH of the wastewater to less than 3, introducing an excess of iron ions - III and introducing a pre-prepared suspension of ferrohexane cyanoferrate. After clarification of the wastewater solution at the 2nd sedimentation stage, the clarified solution is treated with sodium alkali to precipitate an excess of iron ionosis - III, the precipitate is separated, and the solution is neutralized and discharged into the water intake or municipal sewage system. The method makes it possible to achieve a residual concentration of radionuclides in the solution, which lies below the detection plate, and to significantly reduce the residual concentrations of phosphates, iron and anion-active surfactants. 3 hp f-ly.
