采用流体化床Fenton装置深度处理合成制药废水,通过正交试验确定了处理合成制药废水的最佳条件是HRT为20min,初始pH值为4.0,H2O2/CODcr(质量比)为4.0,H2O2/Fe2+(摩尔比)为15,且在最佳条件下出水CODcr稳定在80mg/L以下,可以达到《污水综合排放标准》(GB8979-1996)一级标准。同时将其与标准Fenton氧化法进行对比试验,结果显示流体化床FentonCODcr去除率可提高13%以上,污泥产生量可降低70%,运行成本可减低28%,稳定运行成本可以控制在3.0元/吨废水以内。

The fluidized-bed Fenton reactor was employed for advanced treatment of synthesis pharmaceutical wastewater.Through orthogonal tests,the best reaction conditions for synthesis pharmaceutical wastewater treatment were determined as 20 min of HRT,4.0 of initial pH value,4.0 of H2O2/CODcr mass ratio and 15 of H2O2/Fe2+ Moore ratio.Under those optimum conditions,CODcr concentration of the effluent was detected stably below 80 mg/L,which complies with the Class A of Integrated Wastewater Discharge Standard(GB8978-1996).Comparing to the standard Fenton oxidation,the application of fluidized-bed Fenton reactor resulted in an improvement of over 13% on CODcr removal efficiency,as well as a reduction of 70% on sludge yield.Accordingly,the operating costs can be reduced by 28%,which could be controlled within 3.0 yuan/tons wastewater in stable conditions.
