采用自制多光源光化学反应器,研究了聚丙烯酰胺在O3/H2O2/UV体系下光化学降解反应的动力学规律,考察了各个因素对HPAM光化学降解速率的影响。结果表明,该反应体系对HPAM有较好的去除率,在任何特定反应条件下,HPAM的降解速率均与HPAM的质量浓度成正比。并且,此体系下优化的降解条件为：紫外灯功率为96 W,初始臭氧浓度为1.50 g/h,初始双氧水浓度为0.83 g/h,初始pH为4,HPAM初始浓度为50 mg/L。在此基础上建立的HPAM降解反应动力学模型对其在光化学氧化体系中降解动力学规律具有良好预测性。

The photochemical kinetics of HPAM in O3/H2O2/UV system with multi-photochemical reactor was investigated.Besides,the effects of operating parameters were investigated.It was found that PAM was degraded efficiently by O3 /H2O2 /UV processes,and the degradation rate of PAM was in direct proportion to the PAM concentration.In addition,the optimum degradation condition was UV power controlled at 96 W,initial O3 concentration at 1.50 g/h,initial H2O2 concentration at 0.83 g/h,pH value at 4 and initial HPAM concentration at 50 mg/L.The degradation dynamics model was estabilished based on above study,which has favorable forecast on degradation kinetic rule in photochemical oxidative system.
