摘要(Abstract)：

耦合太阳光催化氧化和有机膜分离技术,设计了一种新型太阳光催化氧化-膜分离三相流化床反应装置(简称反应装置),并对平均粒径0.22μm颗粒状TiO2催化剂在反应装置中的悬浮性能进行了研究。结果表明:增加TiO2投加量和光催化反应区曝气量均使TiO2悬浮浓度升高、直至最大平衡悬浮浓度,同时TiO2沉积现象亦随之变得严重,最佳曝气量和TiO2投加量分别为0.30 m3·h-1和10.00 g。气冲洗使反应装置中TiO2悬浮浓度保持恒定,且适宜的气冲洗时间和气冲洗时间间隔分别为10 s和40 min。连通管上的阀门全开时膜分离器中TiO2悬浮浓度始终大于半开时的,而气冲洗前管式反应器中TiO2悬浮浓度在阀门全开时小于半开时的;膜出水对TiO2悬浮性能的影响很小。
