附录 1 英文文献 Modeling of organic pollutant destruction in a stirred2tank reactor by ozonation CHENGJiang1 , YANG Zhuo2ru1 , CHEN Huan2qin1 , KUO C.

Ozonation reactor design and process optimizing require the modeling of the gas2liquid 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 semi2batch 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 ,42dichlorophenol (2 ,42DCP) and 2 ,62DCP or their mixture are chosen as the model compounds for simulating , and the predicted DCP concentrations are compared with some measured data. Keywords : dichlorophenol destruction ; ozonation ; stirred2tank reactor ; enhancement factor Introduction Because of the high oxidation potential of ozone (O3 ) , ozonation has been regarded as a promising method for drinking and waste water treatment. A wide range of organic pollutants in water can be degraded by O3 , O3 combined with H2O2 or UV light , which are known as Advanced Chemical Oxidation Processes (AOPs) . Compared
