Abstract	Decoloration and mineralization of yeast wastewater were investigated by using Ce-Fe/Al$_{2}$O$_{3}$ as a heterogeneous photo-Fenton catalyst in fluidized bed reactor in order to solve the problem of yeast wastewater discharge. The experimental results were assessed in terms of total organic carbon(TOC) reduction. The operational and reaction conditions affecting the efficiencies of TOC removal such as initial pH value, H$_{2}$O$_{2}$ concentration, catalyst loading and UV power were studied. The results show that TOC is reduced from 347.6 mg/L to 10.8 mg/L, color is changed from 500 units to 0 under the conditions as follows: initial pH value 6.0, H$_{2}$O$_{2}$ concentration of 1.000 g/L, catalyst loading of 5 g/L, reaction duration of 120 min and reaction temperature of 30 °C. The irradiated Ce-Fe/Al$_{2}$O$_{3}$ catalyst was complexed with 1,10-phenanthroline and then it was subjected to Fourier transform infrared spectroscopy and diffuse reflectance spectroscopy to confirm the formation of Fe(II) in the solid state. Heterogeneous photo-Fenton reaction proves to be effective for the treatment of yeast wastewater.
