摘　　要：本研究以焦糖废水为对象,研究芬顿试剂在超声协同作用下对焦糖废水色度与CODCr处理效果,重点考察了反应时间、H2O2投加量、pH、Fe2+浓度等因素对处理效果的影响。实验结果表明,超声波协同作用能显著提高芬顿试剂脱色率及CODCr去除率;在超声波协同作用下,加入30%H2O26mL,焦糖废水脱色率和CODCr去除率较仅加入等量H2O2分别提高18%与11%;在超声波协同作用下,当pH为3、Fe2+浓度为30mmol/L时,脱色及CODCr去除效果最号,分别为69.5%和62.5%,较仅使用芬顿试剂提高了1.0倍与1.4倍。In this study,the removal efficiency of colorization and CODCr of caramel wastewater was studied,under ultrasonic and Fenton reagent.To investigate the factors influencing,reaction time,dosage of H2O2,pH value,Fe2＋concentration were conducted on caramel wastewater.The results show that the synergy of ultrasonic and fenton reagent can obviously increase the removal efficiency of colorization and CODCr,adding 30 % H2O2 of 6mL,the decolorization rate and CODCr removalrate increased 18 % and 11 % respectively.Under the best conditions（H2O2 6mL,pH 3.0,Fe2＋ 30mmol/L）,the decolorization rate and CODCr removalrate were 69.5 % and 69.5 %.Compared with no-ultrasonic,they were increased by 1 times and 1.4 times.
