A kind of continuous magnetic fixed-film reactor was designed and applied in tetracycline degradation based on the Bi2WO6/ZnFe2O4 magnetic photocatalyst. The effects of light intensity, initial TC concentration and HRT on the photocatalytic effect were investigated. At the pollutant concentration of 51.58 mg/L, light intensity of 3.20×105 lux and HRT of 94 min, the TC removal rate in the reactor was enhanced to above 90% and maximized to 94.05%. From the different pollutant concentrations, the specific outflow criterion could be achieved by regulating the HRT within a certain range, so as to maximize the reactor use efficiency. Compared with conventional fixed-film reactors, the new reactor had larger reaction contact area and avoided the defect of catalyst shedding.
