中文摘要：

以旋转填充床（RPB）作为反应装置，研究了Fenton工艺与Fenton＋O3工艺处理模拟阿莫西林废水的效果，考察了FeSO4·7H2O的投加量、温度、旋转床转速、液体流量及pH对C0D去除率的影响。实验表明，Fenton＋O3工艺的COD脱除率及BOD5／COD相对于Fenton工艺分别提升26．7％和140％。该工艺在pH为3、温度为25℃、液体流量30L／h、气体流量2．5L／h、转速800r／min、H2O2的投加量为1mmol／L及Fe2＋投加量为0．4mm01／L的条件下，100mg／L的模拟阿莫西林废水中COD的去除率达到57．9％，BOD5/COD从0增加到0．36，满足后续生化处理要求。

英文摘要：

The treatment of simulated amoxicillin wastewater by the Fenton ＋ O3 process in a rotating packed bed （RPB） was investigated in this study. The effects of the initial Fe （Ⅱ） concentration, temperature, ro- tating speed,liquid flow rate and pH on the degradation of amoxicillin were explored. The COD removal rate and BODs/COD value in the Fenton ＋ O3 process were 26.7% and 140% higher than that in the Fenton process,re- spectively. The COD removal rate of amoxicillin wastewater in the Fenton ＋ O3 process reached 57.94% with a temperature of 25 ℃ , rotating speed of 800 r/min, pH of 3, H2 O2 concentration of 1 mmol/L, Fe2 ＋ concentration of 0.4 mmol/L, gas flow rate of 2.5 L/h, and liquid flow rate of 30L/h, and BOD3/COD increased significantly from 0 to0. 36,indicating that the as-treated wastewater is suitable for a subsequent biochemical treatment.
