摘　　要：通过氧化源效果对比实验和初始浓度、p H值、UV强度等单因素实验与动力学实验,分析考察了O3/UV的协同氧化作用效果及机理。结果表明:O3/UV氧化效果好于两者单独氧化,并远远高于纯氧和紫外光的单独氧化,O3和UV表现为具有很好的协同氧化作用;单因素实验表明O3/UV对BDE47的降解效率随着p H值的升高和UV强度的增强而升高,氧化实验宜在偏碱性条件下进行;动力学拟合数据表明,O3/UV协同氧化降解BDE47过程模型更加符合伪一级动力学方程模型,其模型参数kobs为0.034。Through the oxidation source effect contrast experiment and single factor experiment such as he initial concentration, pH value, UV intensity and dynamic experiment, we analysised Synergy effect of oxidation and its mechanism. The results indicates： O3 / UV oxidation effect is good than in both single oxidation, and far higher than that of pure oxygen and ultraviolet oxidation alone, O3 and UV oxidation of has the very good coordination; The single factor experiments show that the degradation of O3 / UV to BDE47 efficiency enhanced with the increase of pH value and the intensity of UV, oxidation experiment under alkaline conditions; Kinetic experiments show that the O3 / UV oxidation degradation BDE47 experimental process conforms to the pseudo first-order kinetics equation model, its parameters kobs was 0.0333.
