1Modeling of organic pollutant destruction in a stirred tank reactor by ozonation显示文摘Destruction of organic contaminants in water by ozonation is a gas liquid process which involves ozone mass transfer and fast irreversible chemical reactions. Ozonation reactor design and process optimizing require the modeling of the gas liquid interactions within the reactor. In this paper a theoretical model combining the fluid dynamic and reaction kinetic parameters is proposed for predicting the destruction rates of organic pollutants in a semi batch stirred tank reactor by ozonation. A simple expression for the enhancement factor as our previous work has been applied to evaluate the chemical mass transfer coefficient in ozone absorption. 2,4 dichlorophenol (2,4 DCP) and 2,6 DCP or their mixture are chosen as the model compounds for simulating, and the predicted DCP concentrations are compared with some measured data.CHENG Jiang YANG Zhuo-ru CHEN Huan-qin KUO C.H.
