摘　　要：在旋转填充床(RPB)中,采用O3-Fenton氧化法深度处理实际彩涂废水。实验结果表明:在反应温度为25℃、气体流量为150 L/h、液体流量为30 L/h、初始p H为7、反应时间为5.0 min、Fe2+浓度为0.10 mmol/L、H2O2浓度为1.0 mmol/L、RPB转速为1 000 r/min的条件下,彩涂废水的COD去除率达到99.7%,比非超重力O3-Fenton体系的处理效果高出60.0百分点。表明超重力技术对O3-Fenton氧化法深度处理彩涂废水具有良好的强化效果。The effluent of actual color-coated plate production wastewater after bio-treatment was treated by the O3- Fenton oxidation process in a rotating packed bed （RPB）. The experimental results showed that： Under the conditions of reaction temperature 25 ℃, gas flow 150 L/h, liquid flow 30 L/h, initial pH 7, reaction time 5 min, Fe^2＋ concentration 0.10 mmol/L, H202 concentration 1.0 mmol/L and RPB rotating speed 1 000 r/min, the COD removal rate of the wastewater is 99.7%, which is 60.0 percentage point higher than that by O3-Fenton oxidation without high gravity. These results indicate that high gravity technology has good enhancement effect on advanced treatment of color- coated plate production wastewater by O3-Fenton oxidation process.
