| 摘 要： | 针对低水平放射性废水的特点,结合人工湿地的去除机理,对湿地植物、基质和微生物在放射性废水处理中的原理和作用进行了分析,分析认为湿地植物通过植物提取、根际过滤和植物固定对低放重金属进行去除,基质的吸附和微生物的吸收、吸附及转化作用也是低放重金属去除的重要途径。并且阐述了当前的技术难点和未来的研究方向,指出在植物培育与选择、微生物的筛选及驯化、基质的选择和湿地系统的安全措施等方面还存在很多的难点。分析表明,应用人工湿地处理低水平放射性废水在技术上是可行的。

| Abstract: | Based on the character of low level radioactive liquid waste and the mechanism of constructed wetland,the theory and process were analyzed about wetland plants,media and microorganism in the radioactive liquid waste treatment,the analysis showed that low level radioactive heavy metal can be treated by wetland plants from phytoextraction,rhizofiltration and phytostabilization,on the other hands,media adsorption and microbial assimilation,adsorption,transform are the importance process.At the same time,they w... |
