摘要
针对油田含油污水中石油烃类的特点及催化剂在污水中存在的形式 ,采用结构不同的半导体TiO2 为催化剂 ,研究了光催化处理含油污水的可行性 ,并对不同催化剂的活性进行了比较 ,考察了催化剂的种类及用量、污水浓度对油田含油污水光催化降解的影响 .结果表明 ,光催化法适合处理低质量浓度的含油污水 ,以超细TiO2 催化剂的活性最佳 ,且粒径越小活性越高 ,催化剂的质量分数以 0 .5 %为宜 .
The feasibility of disposing of oily sewage by using photocatalytic method were studied with several semiconductor TiO 2 catalysts. By comparing the activity of the catalysts, factors such as kinds and dosages of catalysts, concentration of oily sewage that affected photocatalytic degradation was investigated. The results show that photocatalytic method is applicable to treat the low concentration oily sewage, the super fine powder TiO 2 catalyst is optimal, and the smaller the catalyst powder, the higher the catalyst activity, the optimal dosage is 0.5%.
