Abstract
TiO2 photocatalytic membrane reactors (PMRs) are prospective technology of treating dyeing and printing wastewater. The type and structure of the PMRs currently used for dyes wastewater treating were introduced. In these systems TiO2 was successfully separated from water by means of excellent separation performance of membrane, reducing TiO2 loss, enhancing the utilization ratio of catalysts and improving effluent water quality. At the same time dyes and other macromolecular substances were degraded photocatalyticly, greatly improving the stain resistance to membrane and extending membranes service life.
