摘　　要：采用光催化技术和WL型TiO2光催化剂处理炼油厂含油污水,考察了不同类型的催化剂、催化剂的用 量、反应时间、反应温度以及废水的pH值对含油污水的处理效果。实验结果表明:采用WL型TiO2光催化剂、反应 温度30℃、反应时间40 min、pH值为4-8,催化剂用量为1．0-1．5 g／L条件,处理效果较佳:脱油率为98．6％, COD脱除率为99．3％,处理后的废水中油含量和COD值均达到国家《污水综合排放标准》。The photocatalysis technology and WL TiO2 photocatalyst are adopted to treat oily wastewater in refinery. Several kinds of catalysts, usage amount, reaction time and temperature are studied together with the influence of wastewater pH value on treatment effect. The experimental result shows that an excellent treatment is obtained with WL TiO2 photocatalyst under the condition of reaction temperature 30℃, reaction time 40 minutes, waste water pH value 4-8, and the catalyst usage amount 1.0-1.5 g/L. The removal rate for oil is 98. 6% , for COD is 99.3%, and the contents of oil and COD in the treated wastewater have met the national standard of Wastewater Emission.
