| 摘 要： | 设计了一种新型光催化-陶瓷膜分离集成反应器,在反冲条件下利用此集成反应器进行了甲基橙光催化氧化反应,分别考察了陶瓷膜对光催化剂TiO2微粉的截留率、膜的渗透通量、光催化氧化脱色率以及不同膜分离压力下的光催化反应速率常数. 结果表明,TiO2-甲基橙悬浆液体系中TiO2微粉的截留率可达到99.9%, 经集成反应器完成一个反应周期后甲基橙氧化脱色率达到10%, 光催化氧化脱色效果高于圆柱式反应器.

| Abstract: | A photocatalysis-ceramic membrane coupling reactor was designed and used for the photocatalytic degradation of methyl orange. The rejection rate of TiO_2, the filtrate flux, and the degradation rate of methyl orange in this reactor under the condition of back flushing were investigated. The rejection rate of the TiO_2 photocatalyst particles reaches 99.9%. Within one period of partial reflux, the average degradation rate of the methyl orange solution is 10%, which is higher than that obtained in a cylindrical reactor. |
