摘　　要：研究了微曝气Fenton氧化法关键工艺参数对模拟双酚A(BPA)废水处理效果的影响,并从活性污泥性质和污染物去除率两方面,采用膜生物反应器(membrane bioreactor,MBR)对微曝气Fenton氧化法的处理效果进行了实验验证,为实现BPA废水的生物处理奠定基础。结果表明,初始pH值、反应时间、H2O2/COD(质量浓度比)、H2O2/Fe2+(摩尔浓度比)、反应温度及曝气量均对预处理效果有较大影响,在最佳条件下,COD去除率可达70%,BOD/COD值则由原废水的0.02提高到0.50以上。MBR处理上述出水的结果表明,经微曝气Fenton氧化处理BPA的废水,可较好地适应后续的生化处理。The influence of critical operating parameters on the performance of micro-aeration Fenton oxidation process treating synthetic bisphenol A wastewater was investigated. It was validated by membrane bioreaetor （MBR） according to the changes in activated sludge properties and COD removal. The experimental conditions including initial pH, reaction time, H2O2/COD, H2O2/Fe^2 ＋ , temperature and aeration rate greatly affected treatment performance. Under the optimum conditions, the overall COD removal amounted to 70% and the ratio of BOD to COD increased from 0.02 to above 0.50. The pretreated synthetic wastewater by micro-aeration Fenton oxidation process was suitable for biological treatment.
