对采用自制气隙式膜蒸馏装置净化处理质量浓度为1 g/L Sr~(2+)和离子质量浓度均为10 g/ L的 Co~(2+)、Sr~(2+)、Na~+、Ca~(2+)四种离子混合模拟放射性废水进行了研究。结果表明:膜蒸馏技术对1 g/ L Sr~(2+)料液中Sr~(2+)截留率可以达到99.999%以上,去污系数(DF)在105以上;处理离子质量浓度均为10 g/ L的Co~(2+)、Sr~(2+)、Na~+、Ca~(2+)四种离子混合料液时,膜蒸馏对Sr~(2+)、Co~(2+)截留率均接近100%,DF(Sr~(2+))达1×10~6,DF(Co~(2+))达1×10~7;料液温度和料液流速对膜通量有一定影响,无论是提高料液温度,还是增加料液流速,均可以有效提高膜通量。在保证净化效果的情况下,在料液温度75℃,料液流...

Air gap membrane distillation was employed for the treatment of simulate radioactive wastewater including the simple ingredient, which contained only 1 g/L Sr2+, and the complex ingredient that mixed Co2+, Sr2+, Na+, Ca2+ with the mass concentration of 10 g/L, separately. The research results show that the desalination rates of Sr2+ in the simple ingredient of simulated radioactive wastewater achieve 99.999%, and the decontamination factor of which is more than 105. The desalination rates of Sr2+ and Co2+ in the complex ingredient, which mixed ...
