摘要:

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。

Abstract:

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

Key words: circulating fluidized bed, decoloration, degradation, chromatography-mass spectrometry
