三台电渗析法处理反应堆—回路泄漏放射性废水的研究

STUDIES ON TREATMENT OF THE FIRST-CYCLE LEAKAGE RADIOACTIVE WASTE WATER FROM THE REACTOR THROUGH A THREE-STAGE ELECTRODIALYSIS

电渗析技术,五十年代未曾应用于弱放废水的处理上。我国六十年代开始了电渗析技术的应用,七十年代对电渗析法处理弱放废水进行了研究。目前全国工业部门广泛采用电渗析技术来制备高纯工业用水,淡化海水,处理污水和回收工业原料等。本文提出了利用三台电渗析处理反应堆一回路泄漏放射性污染废水的流程,并测得了浓缩比和除盐除放的指标。

This paper presents specification of salt-radioactivity removal through the utilization of a three-stage electrodialysis method in the treatment of reactor first-cycle Leakage Waste Water. Experimental data have shown that it is possible and practical to reduce the relative radioactivity of a Waste Water from 10^(-6) curie/liter in ^(54)Mn and 5×10^(-7) curie/liter in ^(60)Co to nonradioactive water (sp. resistance greater than 150kΩ)through ordinary electrodialysis and high purity electrodialysis; concentration ratio is greater than 100 through ordinary electrodialysis and concentration electrodialysis.
