摘要:
以电离辐照(包括放射性核素产生的γ射线和电子加速器产生的电子束)技术为代表的核技术在环境污染治理,如水和废水处理、烟气脱硫脱硝、地下水修复和污泥处理等方面的研究日益引起人们的关注。电离辐射是一种相对简单并可实现大规模工业废水处理的高级氧化技术,具有实际应用潜力。综述了电离辐照在去除水中氯酚类、PPCPs等毒性难降解有机污染物、处理染料、造纸等工业废水、去除铬、汞等重金属离子以及水体消毒方面的研究和应用进展;分析了有机污染物的辐照降解机理和主要影响因素;介绍了电离辐照与其他技术联用强化有机污染物降解的研究。最后对该技术的研究和发展方向提出了建议。

Abstract:
Ionizing irradiation technology (including gamma ray and electron beam) has received increasingly attention in the environmental applications, such as water and wastewater treatment, desulfurization and denitrification of flue gas, remediation of groundwater, sludge treatment. It is a relatively easy and has a great potential in the field of industrial wastewater treatment in large scale. In this review paper, the progress of research and application of ionizing irradiation for water and wastewater treatment is introduced, including the removal of toxic and recalcitrant pollutants (such as chlorophenols, PPCPs) and heavy metal ions (such as Cr6+ and Hg2+) from aqueous solution, the treatment of industrial wastewater (such as dyestuff and paper mill effluent), as well as the disinfection of water and wastewater. The mechanism and major influencing factors of radiation-induced degradation of pollutants are analyzed. The combination of ionizing radiation with other technologies to enhance the pollutants removal is present. Finally, some suggestions on the future research and development are proposed.
