A new type of reactor with TiO_2/GeO_2 composite membrane was made for photocatalytic oxidation of reactive blue in dye wastewater. The wastewater was treated first by ozone and then by the reactor. The photocatalytic oxidation degradation of reactive blue was studied. When the H_2O_2 dosage is 400 mg/L and the illumination time is 120 min, the COD removal rate is 92.5% and the COD of the treated wastewater is 39.4 mg/L, which can meet the national discharge standard of GB8978-1996.
