放射性废水处理技术研究进展

STUDY PROGRESS OF TREATMENT TECHNOLOGIES FOR THE RADIOACTIVE WASTE WATER

放射性废水是核能利用过程产生的废水,具有重金属元素种类多和浓度高,有放射性,对人和动物危害大的特点,因此研究放射性废水处理具有重要意义。综述诸如化学沉淀法、离子交换法、蒸发浓缩法、吸附法、膜处理法、生物反应法、离子浮选法等在放射性废水处理研究中的应用以及各技术联用现状,并在此基础上对未来发展趋势进行了展望,提出了石墨烯这一新型材料所具有的巨大潜力和利用超重力技术进行改进的研究思路。

Radioactive wastewater is waste water generated in the nuclear energy using process.Which features various heavy metal elements,high-concentration,radioactivity and harmful to human being and animals.Therefore,it is of great significance to research radioactive wastewater treatment.The paper introduced the application and combination status of the radioactive wastewater treatment technology,such as chemical sedimentation,ion exchange,evaporation concentration,adsorption method,membrane separation,biological treatment,ion flotation method.The future development trend is discussed on a basis.It is proposed that a new type of material—graphene,has huge potential and super-gravity technology can be used to improve the research.
