| titleOfInvention | Uranium and the recovery method of fluorine in hex Alkali absorption liquid waste liquid |
| abstract | The invention discloses uranium and the recovery method of fluorine in hex Alkali absorption liquid waste liquid, first by the acid acidifying of hex Alkali absorption liquid waste liquid, regulate pH=2.7 ~ 5.5, add polymeric sorbent polystyrene Cyclohexylamino maleic acid and complete UO 2 2+ Absorption, solid-liquid separation by gained solid with 1 more than M acid desorption realize UO 2 2+ Recovery, surplus solution add Na 2 CO 3 Carry out the drip washing of subsequent cycle hex, in time circulating more than 5 times, rich in the F of high concentration in solution ‑ .Adding NaCl in solution makes NaF separate out because dissolubility reduces to saturated, NaF solid is recovered by filtration to obtain, adds CaCl in solution 2 , CaO or Ca (OH) 2 Solid or its saturated solution make the F of residual ‑ Form CaF 2 Precipitation, degree of depth fluorine removal.Finally achieve uranium and the recovery of a large amount of fluorine in uranic hexafluoride gas Alkali absorption liquid waste liquid.Present invention achieves the recovery of uranium in radioactive liquid waste and the zero-emission of waste liquid, make the discharge of waste liquid be up to state standards, solve the problem that in tradition defluorinating process, a large amount of calcium fluoride are difficult to filter simultaneously. |
