摘要/Abstract

摘要：

在介绍电子束辐照机理的基础上,概述了其在环境保护中的应用,并着重从降解有毒有害和难降解的有机污染物、重金属离子的去除等方面对国外就电子束辐照在水处理中的研究和应用现状进行综述,最后对电子束辐照和其他的水处理工艺进行了比较,就其自身可以实现对有毒有害有机物混合液的同时处理、与γ辐射相比具有操作方便、安全的特点,但是自由基与有机物反应的选择性差、易受自由基消耗剂的影响,所需剂量一般较大。并对其在水处理中的应用前景进行了展望。

Abstract:

On the basis of the introduction to the mechanism of elect ron beam i rradiation, the paper describes it sapplication to environmental protection, especially the present situation of its application to water t reatment,from the ang les of the degradation of hazardous and undegradable organic pollutant s, the removal of heavy metal,and so on in foreign count ries.Then, comparisons between electron beam irradiation and o ther water treatmenttechnologies are made, according to its characterist ics, such as being able to treat mixed liquid of poisonous andhazardous o rganic matter simultaneously and being more, convenient and save when compared with irradiation, and its limitat ion, such as i ts bad selectivi ty, easy effect by radical scavenger, and the high dose needed,the paper discusses the promising future of it s applicat ion in water treatment.
