摘　　要：利用电子加速器产生的高能电子束为辐照源,对较高浓度的活性染料活性红m3BE进行了辐射降解研究,探讨了H2O2加入量、吸收剂量对辐照降解结果的影响和辐照前后溶液pH值的变化。结果表明,电子束辐射能有效降解活性红m3BE,脱色效果显著,脱色率达100%,化学需氧量(COD)去除率可达47%,经2.3kGy剂量辐照后溶液的pH值已有明显下降。H2O2加入量、吸收剂量均与活性红m3BE的降解效率有关,溶液pH值的变化可能有利于提高废水的可生物降解性。实验证实,利用电子束辐射降解技术处理染料废水是一种可行的方案。Degradation of active red m-3BE in aqueous solution under high energy electron beam irradiation was investigated. Active red m-3BE in aqueous solution was irradiated by electron accelerator at absorbed doses of 2.0 to 27.8kGy. The absorption spectra and COD were examined under different absorbed doses. Results showed that dye has got a high rate of decoloration, with decolorization and COD removal efficiency of 100% and 47% respectively. Results of experiments showed high energy electron beam is feasible to treat dye wastewater.
