Zusammenfassung:A novel highly efficient technology, intimate coupling photocatalysis and biodegradation (ICPB) for the treatment of refractory organic pollutants was introduced, and the carrier in ICPB based on sugarcane bagasse cellulose (SBC) was prepared. The SBC–TiO 2 carrier produced was characterized using spectroscopy, microscopy, and diffraction techniques. The SEM image showed a rough and porous structure of the carrier, while as the EDS, XPS and XRD indicated that TiO 2 was successfully added into the carrier, which retained its original crystal structure and provided the photocatalytic activity. The combined process of photocatalysis and biodegradation was much more efficient than a single process alone. The success in preparing bagasse cellulose based carrier in this study provided a significant contribution towards the development of a green and efficient technology system for the treatment of refractory organic matter.
