A STUDY ON TREATMENT OF PAPERMAKING WASTEWATER BY WO3/α-Fe2O3/W AS HETEROGENEOUS PHOTOCATALYST

doi:10.7517/j.issn.1674-0475.2001.02.131

Abstract

Abstract: Papermaking wastewater was treated by a photocatalytic oxidation process. Reaction mechanism of photocatalysis was probed. The active order of photocatalyst was compared. The effects of primary factors on the removal efficiencies of COD and colority were discussed. The experimental results indicate that the removal efficiencies of COD and colority in papermaking wastewater can reach 68.3% and 71.2% respectively by using WO₃/α-Fe₂O₃/W as heterogeneous photocatalyst, with the composition of heterogeneous photocatalyst=75:24:1, quantity=0.500 g, pH= 6.5, illumination=22 h.

Key words: heterogeneous photocatalyst, papermaking wastewater, removal efficiency, tungsten trioxide
