Abstract

Using nickel oxide and ferric oxide materials, and ceramsite as carrier, the catalysts have been prepared by impregnation method including single-component and multi-component catalysts. The single-component and multi-component catalysts were used to study the COD removal performance of pharmaceutical secondary effluent respectively. First, the factors preparation parameters (i.e., calcination temperature and calcination time) of Ni_xO-Fe_xO/ceramsite and operational parameters (i.e., initial pH and the catalyst dosage) of O₃-Ni_xO-Fe_xO/ceramsite system were optimized, respectively. The results showed that the optimum conditions of Ni_xO-Fe_xO/ceramsite catalyst oxidation reaction were as follows: calcination temperature is 600°C, the calcination time is 5 h, the optimum catalyst dosage is 8g/L, the initial pH is in alkaline condition, which is more conducive to the reaction. The average COD removal rate of the effluent can reach about 80% under the above best conditions. then, characteristics of the Ni_xO-Fe_xO/ceramsite catalysts were studied through scanning electron microscopy (SEM), X-ray fluorescence (XRF) and X-ray diffraction (XRD), respectively. The results show that Nickel and iron oxides was uniformly deposited on the ceramsite surface when Ni_xO-Fe_xO/ceramsite was prepared. Finally, The stability of the catalyst in the system of O₃-Ni_xO-Fe_xO/ceramsite was studied. Collectively, these results suggest that the Ni_xO-Fe_xO/ceramsite should be proposed as a promising catalyst for the decomposition of ozone.
