Composite material(TiO2/BFSF) of TiO2 loaded on blast furnace slag fibre(BFSF) was prepared by impregnation-depositing process using BFSF as the carrier. The crystal form,grain size,specific surface area of TiO2 and microstructure of the composite TiO2/BFSF were characterized by XRD,particle size analyzer and Zeta potential meter,N2 adsorption and desorption instrument,SEM and EDS,respectively.The photocatalysis performances of TiO2/BFSF were evaluated by degradation of methylene blue(MB) simulating dyeing waste water. The results show that with 3 times of impregnation-depositing in 20 g/L TiO2 suspension system,TiO2 can be uniformly coated on the BFSF and 94.8% MB can be degraded by composite TiO2/BFSF under the ultraviolet light irradiation for 180 min.After 4 times of recycle the degradation rate of MB is still maintained at 65%.
