摘　　要：以超重力旋转填充床(RPB)为反应装置,研究了O_3/UV工艺处理罗丹明B染料废水的效果。考察了旋转填充床转速、液体流量、催化剂P25质量浓度、臭氧质量浓度等因素对脱色率和COD去除率的影响。结果表明,随着旋转填充床转速、液体循环量、催化剂P25质量浓度以及臭氧质量浓度的增加,罗丹明B废水的处理效果增加;当温度为25℃、液体体积为2 L、RPB转速为1 000 r/min、废水pH为4、气体体积流量为150 L/h、液体循环量为30 L/h、臭氧质量浓度为35 mg/L、催化剂P25质量浓度为400 mg/L时,罗丹明B废水经处理20 min后脱色率和COD去除率分别可达100%和40%。The treatment effect of Rhodamine B dye wastewater by the O3/UV process is studied in a rotating packed bed( RPB). Influences of RPB rotating speed,liquid circulating flow rate,dosage of P25 catalyst,ozone( O3)concentration on the decolorization and COD removal efficiency are investigated. Study results show that the treatment effect of Rhodamine B wastewater increases with the increase of RPB rotating speed,liquid circulating flow rate,catalyst P25 dosage and ozone concentration.The decolorization and COD removal efficiency reach 100% and 40%,respectively after the wastewater has been treated for 20 minutes at 25℃,a RPB rotating speed of 1,000 rpm,a liquid flow rate of 30 L·h-1,a pH of 4,a gas flow rate of 150 L·h-1,an O3 concentration of 35 mg·L-1 and a catalyst P25 dosage of 400 mg·L-1.
