Abstract
A new type of a non-light concentrating solar photoreactor with immobilized catalyst was developed, where a flat and transparent structured box made of polymethylmethacrylate comprised the main body, and immobilized TiO2 membrane supported on glass fiber net with sol-gel method was used as catalyst. Phenol was used as model pollutant to evaluating the device performance. The limitation of mass transfer was diminished when the circular flux exceeded 2L/min. The apparent reaction kinetics was first order with respect to the phenol concentration, and the apparent kinetic constants decreased with the increase of initial concentration. The linear dependence between apparent reaction rate and radiation density flux was found from 12.8 to 47.6 W/m2. The new reactor, which treated phenol in tap water with high efficiency, has a promising prospective in real drinking water treatment.
