In this study, two integrated system, composed of UV-photocatalytic reactor loaded with different photocatalyst media and fluidized biofilter in series, were constructed to compare their efficiency for the treatment of real textile wastewater. The real textile wastewater containing various dyes, surfactants, polyvinyl alcohol(PVA), hydrolyzed polyester and other recalcitrant organic substances, was fed to a fluidized biofilter, after which the fluidized biofilter-treated wastewater entered into UV/photocatalytic process. The return-sludge obtained from a textile wastewater treatment facility located in Daegu, was immobilized at the fluidized media in the biofilter and the photocatalytic reactor was filled with TiO2 coated-1) porous silica media or 2) glass bead media. For the case of TiO2 coated-porous silica media, the COD values of feed, biofilter-treated wastewater and the effluent from photocatalytic reactor were 1800ppm, 350-380ppm and 200-300ppm, respectively. For the case of TiO2 coated-glass beads media, the COD values of feed, biofilter-treated wastewater and the effluent from photocatalytic reactor were 1800ppm, 350-380ppm and 315-340ppm, respectively. Thus the COD removal efficiency of the integrated system with TiO2 coated-porous silica bead media was maintained at 83-89% while the COD removal efficiency of the integrated system with TiO2 coated-glass bead media was maintained at 79-86%. Moreover, for the case of TiO2 coated-porous silica media, the ADMI color values of feed, biofilter-treated wastewater and the effluent from photocatalytic reactor were 1300, 500-630 and 230-550ppm, respectively. For the case of TiO2 coated-glass bead media, the ADMI color values of feed, biofilter-treated wastewater and the effluent from photocatalytic reactor were 1300, 500-630 and 550ppm, respectively. Thus the color removal efficiency of the integrated system with TiO2 coated-porous silica bead media was maintained at 58-82% while the color removal efficiency of the integrated system with TiO2 coated-glass bead media was maintained at 58%. It is suggested that the type of TiO2 coated-media is important to determine the characteristics on the whole integrated system
