| Abstract:To solve the problems of large amount of iron sludge and high cost in the traditional homogeneous Fenton method for the deep treatment of papermaking wastewater， Fe-derived Fenton catalysts were prepared by high temperature sintering of Fe2O3， Al2O3， SiO2， and graphite powder， which was used in the non-homogeneous Fenton treatment of papermaking wastewater to achieve the effect of saving the dosage of FeSO4. The results showed that the Fe-derived Fenton-like catalyst prepared by high-temperature sintering had a rich pore structure. Under the conditions that pH value of 3， catalyst dosage of 15 g/L， mass ratio of CODCr and H2O2 of 1∶0.75， and reaction time of 90 min， the removal rate of CODCr was up to 74.8% and more than 70% even after 10 cycles of experiments. The removal rate of BOD5 could be more than 67%. |
