METHOD FOR THE DECONTAMINATION OF A RADIOACTIVE LIQUID EFFLUENT WITH ONE OR MORE RADIOACTIVE CHEMICAL ELEMENTS BY SOLID-LIQUID EXTRACTION USING A RECYCLING LOOP |
摘要 |
<p>The invention relates to a continuous process for decontaminating a radioactive liquid effluent comprising one or more radioactive chemical elements to be removed that comprises the following steps: a step of bringing said radioactive liquid effluent into contact, in a first reactor, with solid particles capable of capturing and retaining said radioactive chemical element(s) to be removed, by means of which a suspension of solid particles containing said radioactive chemical element(s) to be removed is obtained; a step of settling said suspension, in a second reactor, by means of which a solid phase is obtained that comprises the solid particles containing said radioactive chemical element(s) to be removed and a liquid phase depleted or devoid of said radioactive chemical element(s) to be removed; a step of separating said solid phase and said liquid phase; characterized in that a portion of said solid phase obtained at the end of the settling step is reinjected into the first reactor for the implementation of a contacting step as defined above. Application to the treatment of radioactive liquid effluents originating from nuclear installations.</p> |
