Embodiment Construction
[0016] The present invention will be described in further detail below in conjunction with specific embodiments.
[0017] A kind of saturated resin hydrochloric acid protonation transition water rinsing process, comprises the steps:
[0018] (1) Select a high-efficiency leaching agent (such as clear water) to improve the leaching efficiency, reduce the concentration of uranium in the adsorption tail liquid, and prevent the occurrence of resin poisoning and tower blockage;
[0019] (2) Select a suitable eluting agent (such as clear water) to reduce the impurity content in the qualified liquid and improve product quality;
[0020] (3) Adopt appropriate rinsing process to reduce HCO in ground immersion solution 3 _ consumption.
[0021] The 738 factory selected in this example is located in a desert area, and there is a shortage of clean water. If the resin hydrochloric acid is protonated, a large amount of water will be needed for flushing. If it is directly returned to adsor...
