Treatment Method of Radioactive Waste Liquid Containing U and Cs

Radioactive waste liquid will not only cause heavy metal and radiation pollution in the environment, but also enter the human body from a variety of ways, threatening human life and health. Among them, uranium and cesium, due to their high fission yield, long half-life and high solubility of salt compounds in water, need to be treated urgently. The treatment methods of radioactive u and C waste liquid, such as ion exchange method, solvent extraction method, adsorption method, membrane separation method, chemical precipitation method, biological treatment method, adsorption method and combined process, are combed. The principle, characteristics and application of the method are reviewed, and the research direction and development trend are prospected. It has a certain reference value for the selection of radioactive waste treatment methods in different situations.
