摘　　要：随着核能的发展和环保意识的增强,核设施中氚的排放越来越引起人们的重视。为了有效地控制液态氚的排放,针对内陆核电、国际热核聚变实验堆和福岛核电站3种含氚废水(轻水)体系开展了基于联合电解催化交换工艺的深度净化除氚的技术研究,系统性地评价了所需要的理论塔板数与不同除氚目标和富集程度的关系;并进一步分析了含氚轻水处理量与天然水消耗量之间的关系。结合上述分析,最后给出了具体的工艺设计示例,并提出了在含氚水进料量较大的情况下,宜采用模块化的设计方案。With the development of nuclear energy and the enhancement of environmental protection awareness, the emission of tritium in the facility has attracted more and more attention. In order to effectively control the emission of liquid tritium, the detritiation study for the tritiated water from inland nuclear plants, international thermonuclear experimental reactor and Fukushima nuclear plant based on the combined electrolysis and catalytic exchange process was explored. In this work, The relationship between theoretical plate number and various target of decontamination factor and enrichment factor was systematically evaluated. Furthermore, the relationship between feed rate of tritiated light water and natural water was illustrated. Combined with the detailed analysis, a specific process design example was given, and the modular design scheme was proposed in the condition of treating large amount of tritiated water.
