本文的实验结果表明:沸石串联柱,对~(137)Cs的去污因素达到1000,浓缩倍数可达到500.钛酸钠交换柱,对~(90)Sr的去污因素为1000时,浓缩倍数为1800.负载~(137)Cs的沸石和负载~(90)Sr的钛酸钠在900℃下煅烧,失去交换性能,可作为固体废物贮存,也可直接与水泥渗合,固化,本法处理碱性放射性废水澄清液,对Cs和Sr的去污因素和浓缩倍数都比较高,可减少最终贮存固体废物的体积,降低Cs,Sr在水泥中的渗出,对安全贮存放射性固体废物是有利的.
The experimental results show that the concentration of decontamination factor of ~ (137) Cs reaches 1000, and the concentration ratio can reach 500. In sodium titanate exchange column, when the decontamination factor of ~ (90) Sr is 1000, Multiples of 1800. The zeolite loaded with ~ (137) Cs and sodium titanate loaded with ~ (90) Sr calcined at 900 ℃, losing the exchange performance, can be stored as solid waste, can also be directly infiltrated with cement, curing The method of treating alkaline radioactive waste water clarification liquid has relatively high decontamination factors and concentration multiples of Cs and Sr, which can reduce the volume of final solid waste storage and reduce the exudation of Cs and Sr in cement, and has the significant effect on safe storage of radioactive solid waste It is good.
