摘　　要：以60Co-γ和高能电子束为辐照源,对TCA和DCA水溶液以及模拟水加氯消毒后的水溶液进行了辐照降解研究。结果表明:辐照技术能有效地降解饮用水氯化消毒副产物,并且还能够抑制消毒副产物的进一步生成,这对于消毒后饮用水质量的保持有着十分重要的意义。TCA and DCA solution and simulated chlorine tapewater were decomposed with ()^(60)Co-γ and high energy electron beam irradiation systems. Results showed irradiation can effectively decompose disinfection by-products (DBPs) of chlorination and restrain the further generation of DBPs, which was very important for keeping the quality of drinking water.
