117β-雌二醇的生物降解性能研究显示文摘 采用活性污泥静态搅拌试验,通过LC-MS分析了17β-雌二醇(E2)在不同污泥量、不同初始浓度等条件下的去除情况,考察了其生物降解性能。结果表明,在不同工况下污水厂的活性污泥对E2有很好的降解性,其动力学特性呈一级反应,20℃下反应速率常数为3.29/h。细菌失活试验表明活性污泥对E2的吸附作用很小。李富生 何义亮 汤浅晶 小原彩 Alexander P.Mathews 2003中国给水排水2003,19,6:14
2多孔电极臭氧发生器氧化废水中有机物的吸收和反应动力学分析(英文)显示文摘A novel electrode design for the in situ generation of ozone in the reaction zone of a tubular reactor is described in this work.The ozone generator uses a porous inner electrode tube in the corona discharge assembly,and the ozone generated around the outer periphery of the porous tube diffuses into the tubular reactor and reacts with the contaminants in the fluid that is being treated.A mathematical model that includes absorption and second order reaction in the film is developed to describe ozonation kinetics of a contaminant dye in the tubular reactor.The model describes the experimental data for dye decolorization,oxidation byproducts,dissolved ozone,and ozone gas concentrations well.Model analysis indicates that the fast dye decolorization reaction occurs partly in the liquid film and partly in the bulk fluid.The model can be used in the selection of appropriate gas-liquid contactors for efficient oxidation of contaminants in effluents.Alexander P.Mathews Kishora K.Panda 2012Chinese Journal of Chemical Engineering2012,20,3:0
