Application of Ultrafine-Ti_O_2 Particles as Photocatalyst in Aqueous Suspension and Separation of Particles with Ceramic Membrane

摘要

For solving the problems of ultrafine-catalysts' application for photodegradation of organics in wastewater, and recovery of catalysts for reuse, we studied the-effects of TiO_2 particle size on photocatalytic degredation in aqueous suspensions and its recovery by crossflow microfiltration of waterwater containing TiO_2 particles with ceramic membrane. And the equipment for the series process involving photodegradation and seaparation was developed. The results were as follows.
