%X The effluent from the secondary settling tank of a textile industrial park wastewater treatment plant was subjected to photocatalytic degradation with the titania and UV light in a slurry photocatalytic membrane reactor (PMR),where titania particles were separated by hollow fiber microfiltration membranes.The influences of the dosage of photocatalyst,reaction time,dissolved oxygen (DO),mixture methods on photocatalysis efficiency and membrane separation processes were investigated in detail.The results showed that TiO2 dosage,DO and mixture methods significantly influenced the performance of PMR.The best dosage of photocatalyst was 1 g/L and the blast mixture was more fitted for PMR than the mechanical mixture.After treated by PMR,the effluent from the secondary settling tank of a textile wastewater treatment plant could match Discharge Standards of Pollutants for Dyeing and Finishing of Textile Industry(GB 4287-92)(Class I)and Miscellaneous Domestic Water Quality Standard (CJ/T 48-1999).
