摘　　要：采用Fe2O3掺杂TiO2为催化剂,超声辐照为主要手段对实际糠醛废水进行了降解试验研究,考察了各种反应参数对糠醛废水降解效果的影响。结果表明,Fe2O3掺杂TiO2对糠醛废水的超声降解效果具有明显的辅助和提高。当超声波频率为40 kHz,功率为160 W,初始COD为1 128 mg.L-1,超声反应时间为1.5 h的条件下,糠醛废水的COD去除率为67%,而同样条件下,按质量浓度750 mg.L-1加入1.0%Fe2O3掺杂量的催化剂TiO2,其超声降解废水COD去除率可达95%。The effect of nano Fe2O3 doping TiO2 catalyst on the furfural wastewater degradation undergoing ultrasonic process was investigated. The factors of ultrasonic degradation this wastewater by adopting activated Fe2O3 doping TiO2 catalyst also were studied. The results indicated that the nano Fe2O3 doping TiO2 have positive effect to ultrasonic degradation of the furfural wastewater. The COD removal ratio of the furfural wastewater by ultrasonic process alone achieved 67% within 1.5 h under the experimental conditions such as the ultrasonic frequency of 40 kHz, the output power of 160 W, the wastewater COD of I 128 mg·L^-1 .The COD removal ratio could reach 95% when 750 rag. L4 Fe203 doping TIO2（1.0%） catalyst were dosed in the solution in the same experimental conditions.
