核电厂含硼放射性废液的反渗透处理研究

摘要

Born-containing radioactive waste water was treated by two stage reverse osmosis equipment in order to study the performance of desalting, removing of B and nuclides by the equipment. Results showed that operation pressure should be adjusted in order to avoid decreasing of permeation flux. The two stage reverse osmosis quipment displayed excellent performance of desalting, removing of B. The overall rejection efficiency of salts and B were above 99.50% and 84.30% respectively. Furthermore, 137Cs and 90Sr existing in the waste water could be removed effectively.%文章考察了采用两级反渗透装置、对含硼放射性废水进行处理时,该装置运行过程中脱盐、除硼、核素去除性能等的变化情况.结果表明,反渗透装置在运行过程中,需调节操作压力,以防止膜通量的不断降低;反渗透装置不仅具有优良的脱盐及除硼性能,其中总脱盐率和总除硼率分别保持在99.50%和84.30%以上,同时对废水中放射性核素137Cs和90Sr具有很好的截留效果.
