臭氧水中传质模型的研究

Study on the Ozone Mass Transfer Model in Water

在传统鼓泡塔中对臭氧在水中的传质过程进行实验研究。利用实验改变进水流量、臭氧过气流量以及臭氧进气浓度等，得到臭氧传质系数、臭氧传质效率和臭氧消耗等有关参数。建立一个臭氧传质模型．可以预测不同操作条件下臭氧传质效率，从而优化控制臭氧化反应动力学。

Ozone transfer into potable water was studied experimentally in a conventional bubble col-umn. Liquid and gas flow rates, as well as inlet ozone concentration in the gas phase were varied.Using these experimental data it is possible to determine the ozone mass transfer coefficient,ozone transfer efficiency and ozone consumption. Ozone mass balances have been calculated to de-termine ozone utilization efficiencies. A model of ozone mass transfer in water was established,which allows of the prediction of ozone transfer efficiency in the bubble column at different oper-ating conditions, and optimally control the ozonation reaction kinetics.
