UV/O3降解水样中COD的动力学建模
Kinetics modeling for degradation of COD in water sample by UV/O3
摘要
Abstract
Kinetics modeling can be used to effectively analyze and predict the process of the degradation of organics using the UV/O3 technique.It can also be used to improve the removal rate and reduce power consumption;however,the methods of kinetics modeling that were reported previously cannot be applied when there are unknown organics in the sample solution.Based on the chemical reaction mechanism,a mathematic model that can predict the treatment of a water sample with unknown organic species was established by including the evolution of CO2.The sensitivity of the model was tested under a variety of digestion conditions.Meanwhile,a sample solution mixed with glucose,urea,and potassium acid phthalate was used to validate the accuracy of the model.The experimental and simulated results followed the same trend.关键词
