为满足低放废水处理在放射性废物最小量化和节能降耗方面的要求,研究如何利用连续电除盐技术处理低放废水。选择比较典型的压水堆裂变产物Sr、Co、Cs作为代表性核素。结果表明:与传统的离子交换法相比,连续电除盐具有连续运行、处理效果好等优点,对Sr2+的去除效率可以达到95%以上;随着浓缩倍数的升高,对离子的去除效率降低;对3种模拟核素的去除效率高低顺序为Cs+、Sr2+、Co2+,这种去除效率的顺序与常规离子交换工艺不同。

【正文快照】：
环境与社会的可持续发展迫切需要放射性废物最小量化和节能降耗。离子交换工艺和蒸发浓缩是低放射性废水处理的2种常规技术。离子交换工艺会产生大量的放射性废树脂;蒸发浓缩法的能耗高达800元/t。因而这2种常规技术不能完全满足核工业低放废水处理的需求。..........
