Phenol is degraded by biological treatment, however mineralization requires long time. To decrease the time and operational cost necessary for the mineralization of phenol, an optimum operation condition of the combined biological-photocatalytical treatment was investigated. The mineralization of phenol (50 mgl(-1)) was conducted in a flow-type biomembrane tank combined with a batch-type TiO2-suspended photocatalytic reactor. Phenol was degraded biologically to the concentration of 6.8 mgl(-1), an effective concentration for further photocatalytic treatment. After the biological treatment, the biotreated phenol was treated photocatalytically to complete the mineralization of phenol. The combined treatment shortened the mineralization time compared to the biological treatment and electric cost compared to the photocatalytic treatment only. The combined treatment may be suitable for a short-time mineralization of phenol in wastewater. (c) 2006 Elsevier Ltd. All rights reserved.
