对三相内循环流化床式光催化反应器进行优化改造。应用改造后反应器及UV/TiO2技术进行酸性红A废水降解的动力学考察，结果显示：在空气流率为0.8 m3/h，二氧化钛投加量为1 g/L条件下，废水经75 min反应，脱色率接近100%；经400 min反应，总有机碳去除率达到87%。借助液相色谱-质谱的检测，推断出酸性红A可能有的降解路径。

The three-phase internal circulating fluidized bed photocatalytic reactor has been optimized and modified. The modified equipment and UV/TiO2 technology have been applied to the investigation of the kinetics of the degradation of wastewater containing Acidic Red A. The results show that under the following conditions:air flow rate 0.8 m3/h,and titanium dioxide dosage 1 g/L,its decolorization rate is close to 100%after reacting for 75 minutes, and TOC removing rate reaches 87%after reacting for 400 minutes. The possible degradation route of Acidic Red A can be inferred with the help of liquid chromatography-mass spectrometry.
