摘要：

The combination of ozone and UV radiation is useful in removing refractory compounds dissolved in water. In this paper, the decomposition of ozone with UV radiation was investigated by using a rectangular flow reactor equipped with transparent quartz walls. The decomposition rate of ozone in water was proportional to the UV irradiance and the ozone concentration. The dependence on OH** minus ion concentration was very weak compared to decomposition without UV radiation. Data were correlated with an experimental equation which was applicable in the pH range of 2-9. A simulation of ozone utilization in a model reactor indicates that unnecessarily intensive UV radiation destroys ozone in the gas phase before it is transferred into the liquid phase.
