| 摘 要： | 采用UV／Fenton氧化-混凝联合工艺对模拟苯酚废水进行处理，探讨了UV／Fenton预氧化程度和混凝处理条件对模拟苯酚废水处理效果的影响。结果表明，采用混凝处理，COD去除率仅为14．1％；当UV／Fenton预氧化处理过程中H2O2的质量浓度为150～300mg／L时，废水的混凝性能可提高1．5倍以上；当H2O2质量浓度为450mg／L、光反应时间为30min时，采用UV／Fenton氧化一混凝工艺联合处理后COD去除率达82．7％。苯酚废水采用UV／Fenton预氧化处理后，进行混凝处理过程的适宜pH为6．5，混凝剂Fe^3 的适宜质量浓度为500mg／L.

| Abstract: | mulated phenol-containing wastewater was treated by UV/Fenton oxidation-coagulation process. The effects of UV/Fenton preoxidation and the coagulation condition on treatment efficiency were explored. The removal rate of COD is only 14.1% in direct coagulation treatment. When the mass concentration of H2O2 is 150 -300 mg/L in preoxidation, the coagulation efficiency is increased by 150% . When the mass concentration of H2O2 is 450 mg/L, the photoreaction time is 30 min, the removal rate of COD by the combined process is 82.7 % . After pretreatment by UV/Fenton oxidation, the optimum wastewater pH for coagulation is 6.5, and the mass concentration of Fe3+ is 500 mg/L. |
