中文摘要：
采用溶胶凝胶法制备TiO2／Ti电极为光阳极，Cu、Fe、Zn或C为阴极，组成双转盘反应器，以罗丹明B（RhB）为目标污染物，考察了反应条件对光催化效率的影响。结果表明，最佳反应条件：阴极材料为Cu；转盘转速为70r／mira初始pH为2．5；NazSOa质量浓度为1．0g／L,RhB初始质量浓度为20mg／L。在最佳反应条件下，处理RhB模拟废水30min的脱色率可达到99．9％。双转盘反应器处理不同浓度的RhB时，其脱色率是单转盘的1．12～2．33倍，且倍数随着RhB浓度增大而增加，表明双转盘反应器可高效地光催化处理高浓度染料废水。
英文摘要：
TiO2/Ti electrode prepared by sol-gel method was used as anode to assembled a dual rotating disks reactor with Cu, Fe, Zn or C cathode. Rhodamine B （RhB） was selected as target compound, and the main influence factors of RhB photocatalytic treatment were investigated. The optimal conditions were obtained as follow： Cu cathode, rotating speed 70 r/min, initial pH 2.5, Na2 SO4 concentration 1.0 g/L and initial RhB concentration 20 mg/L. Color removal efficiency of RhB solution reached 99.9; after 30 min of treatment under optimal conditions. The decolourization efficiency of RhB solution in dual rotating disks reactor was 1.12 to 2.33 times of that in single rotating disk reactor, and the times increased with increasing the initial RhB concentration. This demonstrated that the dual rotating disks reactor was in favor of high concentration dye wastewater treatment.
