| 摘 要： | 分别采用臭氧氧化、微电解—Fenton氧化和电化学降解的方法处理COD为6 000~8 000 mg/L、BOD5/ COD为 0.12~0.17的光引发剂生产废水,比较了3种方法对废水中COD的去除效果。实验结果表明：臭氧氧化反应2 h时废水COD去除率达35.9%,BOD5/COD 为0.20;微电解反应4 h再Fenton氧化4 h后,废水COD去除率为38.2%,BOD5/COD 为0.28;电化学降解2 h后废水COD去除率达83.9%,BOD5/COD 为0.46,降解反应遵循零级反应动力学,反应速率常数为2.6 kg/（m3·h）。3种方法对光引发剂生产废水的处理效果顺序为：电化学降解>微电解—Fenton氧化>臭氧氧化。

| Abstract: | The photoinitiator production wastewater with 6 000-8 000 mg/L of COD and 0.12-0.17 of BOD5/ COD was treated by ozone oxidation process,micro electrolysis-Fenton oxidation process and electrochemical degradation process respectively. The COD removal effects of the three methods were compared. The experimental results indicate that：After ozone oxidation for 2 h,the COD removal rate of the wastewater is 35.9% and BOD5/COD is 0.20;After micro electrolysis for 4 h and then Fenton oxidation for 4 h,the COD removal rate of the wastewater is 38.2% and BOD5/COD is 0.28;After electrochemical degradation for 2 h,the COD removal rate of the wastewater is 83.9% and BOD5/COD is 0.46,and the degradation reaction followed zero order reaction kinetics with 2.6 kg/（m3·h）of reaction rate constant. The order of the treatment effect by the three processes is：electrochemical degradation > micro electrolysis-Fenton oxidation > ozone oxidation. |
