Abstract:
The present invention provides a treatment method of radioactive waste water containing radioactive cesium and radioactive strontium, comprising passing the radioactive waste water containing radioactive cesium and radioactive strontium through an adsorption column packed with an adsorbent for cesium and strontium, to adsorb the radioactive cesium and radioactive strontium on the adsorbent, wherein the adsorbent for cesium and strontium comprises: at least one selected from crystalline silicotitanates represented by the general formulas: Na 4 Ti 4 Si 3 O 16 .nH 2 O, (Na x K (1-x) ) 4 Ti 4 Si 3 O 16 .mH 2 O and K 4 Ti 4 Si 3 O 16 .lH 2 O wherein x represents a number of more than 0 and less than 1, and n, m and l each represents a number of 0 to 8; and at least one selected from titanate salts represented by the general formulas: Na 4 Ti 9 O 20 .qH 2 O, (Na y K (1-y) ) 4 Ti 9 O 20 .rH 2 O and K 4 Ti 9 O 20 .tH 2 O wherein y represents a number of more than 0 and less than 1, and q, r and t each represents a number of 0 to 10; wherein the adsorbent is a granular adsorbent having a grain size of 250 μm or more and 1200 μm or less, wherein the absorbent is packed to a height of 10 cm or more and 300 cm or less in the adsorption column, and wherein the radioactive waste water is passed through the adsorption column at a linear velocity (LV) of 1 m/h or more and 40 m/h or less and a space velocity (SV) of 200 h −1  or less.

Claim (Index 1):
A treatment method of radioactive waste water containing radioactive cesium and radioactive strontium, comprising passing the radioactive waste water containing radioactive cesium, radioactive strontium, a Na ion, a Ca ion and a Mg ion through an adsorption column packed with an adsorbent for cesium and strontium, to adsorb the radioactive cesium and radioactive strontium on the adsorbent,\n wherein the adsorbent for cesium and strontium comprises:\n at least one selected from crystalline silicotitanates represented by the general formulas: Na 4 Ti 4 Si 3 O 16 .nH 2 O, (Na x K (1-x) ) 4 Ti 4 Si 3 O 16 .mH 2 O and K 4 Ti 4 Si 3 O 16 .lH 2 O wherein x represents a number of more than 0 and less than 1, and n, m and l each represents a number of 0 to 8; and \n at least one selected from titanate salts represented by the general formulas: Na 4 Ti 9 O 20 .qH 2 O, (Na y K (1-y) ) 4 Ti 9 O 20 .rH 2 O and K 4 Ti 9 O 20 .tH 2 O wherein y represents a number of more than 0 and less than 1, and q, r and t each represents a number of 0 to 10; \n wherein the adsorbent for cesium and strontium is a granular adsorbent having a grain size of 250 \u03bcm or more and 1200 \u03bcm or less, wherein the adsorbent has a strength of 0.1 N or more in a wet condition, wherein the absorbent is packed to a height of 10 cm or more and 300 cm or less in the adsorption tower, and wherein the radioactive waste water is passed through the adsorption column at a linear velocity (LV) of 2 m/h or more and 40 m/h or less and a space velocity (SV) of 11 h \u22121  or more and 200 h \u22121  or less.
