用氢氟酸处理的纳米TiO2为光催化剂、以COD去除率为评价指标进行了采油污水的光催化氧化试验,分析了氢氟酸影响纳米TiO2光催化性能的原因,考察了催化剂用量、pH值和外加氧化剂H2O2对氢氟酸处理纳米TiO2光催化反应的影响。结果表明:氢氟酸处理的纳米TiO2,由于F-存在于纳米TiO2表面,改变了表面酸度,增加了有机物的吸附量,使得同等实验条件下采油污水COD去除率得到了提高,其光催化剂和H2O2的最佳使用量分别为10 g/L和80 mg/L,体系的pH值范围为8~10。 Hydrofluoric acid-treated nano-TiO2 as a photocatalyst, COD removal rate as the evaluation index of the oil-bearing wastewater photocatalytic oxidation test, analysis of hydrofluoric acid nano-TiO2 photocatalytic properties of reasons, investigated the amount of catalyst, pH value Effect of Hydrogen Peroxide on the Photocatalytic Activity of Nano - TiO2 with H2O2 as Oxidant. The results show that the hydrofluoric acid-treated nano-TiO2, due to the presence of F- on the surface of the nano-TiO2, changes the acidity of the surface and increases the adsorption capacity of the organic compounds, thereby increasing the COD removal efficiency of the produced wastewater under the same experimental conditions. The optimum dosage of H2O2 was 10 g / L and 80 mg / L, respectively. The pH value range of the system was 8-10.
