摘　　要：设计研制了一种光催化超滤膜反应器,并选用一种颗粒状纳米级TiO2作光催化剂,对染料AcidBlue7光氧化降解进行了研究。影响染料降解的因素包括:错流速度、催化剂浓度、染料初始浓度、溶液的pH值以及曝气条件。研究结果发现,光催化超滤反应器对染料废水处理具有较高的处理效果,且颗粒状光催化剂能够实现良好分离。A set of photocatalysis- ultrafiltration separation reactor for the degradation of Acid Blue 7 as pollutant by nano - particle TiO2 was designed. Tha factors affecting the degradation of dye, including cross-flow velocity, catalyst concentration, initial dye concentration, pH values of solution and aeration conditions were investigated. The experimental results showed that better degradation of dye wastewater was achieved with this reactor and TiO2 particle could be separated from water successfully.
