| 摘 要： | 设计了一种二相流化床光催化氧化反应器，并以耐火砖颗粒为载体，用浸涂法制备了负载TiO2光催化剂。利用此外光为光源，对有机染料直接耐酸大红4BS在不同初始浓度、催化剂浓度、pH值、循环流量和光强下的光催化降解脱色的反应速率进行了研究，并提了该系统的动力学模式。

| Abstract: | A two-phase fluidized bed photo-catalytic reactor was designed and TiO 2-coated photo-catalyst was prepared using firebrick granules as medic in this study. The reaction rate of degradation and decoloration of organic dye 4BS red was studied at different initial concentration, catalyst concentration, pH value, circulation flow and light intensity using ultravionlet lamps as light sourec. A kinetic model of the system was also given. |
