| 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。

| Abstract: | 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 bioreactor(MBR) according to the changes in activated sludge properties and COD removal.The experimental conditions including initial pH,reaction time,H2O2/COD,H2O2/Fe2+,temperature and aeration rate greatly affected treatment performance.Under the optimum conditions,the overall COD removal amounted to 70% and the... |
