电子束辐照处理挥发性有机化合物研究进展

The State-of-the-art of the Treatment of Volatile Organic Compounds with Electron Beam Irradiation

大气中挥发性有机化合物(VOC)的污染对人体健康和生态环境会造成严重的危害, 电子束辐照处理有机气体是较有前途的治理低浓度VOC技术。本文在介绍电子束辐照VOC 机理的基础上,综述了国外关于电子束辐照处理VOC中典型的氯代烃、苯系物以及多环芳烃类污染物的研究进展,阐述了影响VOC去除率的各种因素,介绍了为降低能耗、提高分解效率而采用的加入催化剂、添加剂等方法,并讨论了利用电子束处理VOC的进一步研究方向及应用前景。

The pollution of the Volatile Organic Compounds （VOC） in the atmosphere may do much harm to human health, ecosystem and environment. The technology is promising for treating low concentration VOCs from industrial exhausts. In this paper, the mechanism is introduced., the abroad research progress on removing typical VOC, such as, chloroethylene, benzene and PAHs etc. and the influence factors on decomposing rate are also summerized. The methods on employing catalysts and additive etc. are introduced as well, which is for the sake of reducing energy consumed and increasing decomposition efficiency. The way of futural development, application fields and its future of treating VOC with electron beam irradiation are involved in this paper..
