摘要
在介绍电离辐射降解污染物机理的基础上,概述了电离辐射在水处理中的应用,重点讲述了影响污染物辐照降解的因素,包括水质(污染物初始浓度、pH值、溶剂性质和自由基清除剂)和辐射源(辐射源种类和辐照剂量率)两方面的影响,并讲述了污染物的辐照降解模型。最后提出电离辐射在水处理中存在的问题,对其研究和发展方向进行了展望。
On the basis of the introduction to the mechanism of ionizing radiation, the paper described its application to waste water treatment. Factors influencing radiation - induced degradation, including water quality (initial concentration, pH, solvent and free - radical scavenger) and radiation source (type and dose rate) ware reviewed. Kinetic model of pollutant removal was established, which simulated the influence of the water quality and radiation sources on pollutant decomposition, The problems and the future development direction of ionizing radiation were anticipated.
