Abstract: The immobilized TiO2 film loaded on fiberglass meshes was prepared by sol-gel method. Removal efficiency and influencing factors of sulfamethoxazole (SMX)by the combined process of UV and immobilized TiO2 were studied in detail through pilot test. Results show that SMX can be effectively oxidized by the UV/ immobilized TiO2 process and the first order reaction kinetics model can be used to simulate the oxidation process well. To a certain degree,degradation rate is affected by the initial concentration of SMX and water pH. Lower initial concentration and lower water pH both favor the degradation of SMX. The optimum concentration of H2 O2 for the system is found to be 10μg/L when initial concentration of SMX is 300μg/L. Furthermore,the existence of n-butyl alcohol and KI can reduce the degradation rate of the system on SMX. The reason is that n-butyl alcohol and KI compete with SMX for ·OH. The degradation test of actual water samples which the standard SMX is added to shows that SMX in source water is removed more easily than it in biochemical pool of sewage plant.
