| 中文摘要 | 选择相对分子质量2 000~5 000的水溶性聚丙烯酸钠作为无机纳滤膜处理主要含90Sr1、37Cs6、0Co放射性核素的低水平放射性废水的辅助药剂.重点考察了非放模拟废水的pH值及聚丙烯酸钠投加量对废水中锶、铯、钴等稳定核素截留率及膜通量的影响,并就影响机理做了初步探讨.得到较优的试验条件为:pH值7~8,聚丙烯酸钠体积浓度不低于0.1%.在优化的条件下,进行实际放射性废水的处理试验.结果表明,聚丙烯酸钠辅助无机纳滤膜处理低水平放射性废水是可行的,对总β和总γ的净化率均达到95%左右,且可得到满意的膜通量.; Soluble sodium poly(acrylic) acid(NaPAA) with molecular weight of(2?000)～(5?000) was selected as an assistant reagent of inorganic nanofiltration membrane which was used to treat low level radioactive waste water mainly containing radionuclides()~(90)Sr、(()~(137)Cs) and()~(60)Co.The effect of non-active simulated wastewater pH and NaPAA concentration on the retention efficiency of non-active nuclides strontium,cesium and cobalt ions and membrane permeation flux were explored,and the effect mechanism was also preliminarily discussed.The optimum process parameters were decided: pH 7～8,NaPAA volume concentration no lower than 0.1%.Real radioactive waste water was treated under optimum experiment condition.The results show that the decontamination efficiency of total β and γ emitters of low-level radioactive wastewater were both up to about 95% by inorganic nanofiltration assisted by NaPAA,and the permeation flux was also satisfying. |
