| 摘 要： | 研究了以光催化微臭氧氧化为主体的光化学激发氧化技术,以粉末状二氧化钛(TiO2)为催化剂,对水中腐殖酸进行了光催化氧化研究.探讨了微量O3对腐殖酸的氧化作用,结果表明利用光催化微臭氧氧化法能有效地去除水中腐殖酸.同时对UV/O3、UV/TiO2/空气、UV/TiO2/O3、UV/TiO2/微O34种不同工艺处理微污染水中腐殖酸的结果进行了比较,结果表明UV/TiO2/空气工艺对微污染水中腐殖酸的去除率最低,UV/TiO2/微O3工艺经2 h处理去除率可达70%以上,接近光催化臭氧氧化处理结果.

| Abstract: | The paper deals with the photochemical provocative oxidation whose main part is Micro-O_3 photocatalytic oxidation.And this technology could be used to treat NOM-humic acid(HA) in water.The oxidation of micro-O_3 to HA is also put to study.The result indicates that Micro-O_3 photocatalytic oxidation has an obvious removal efficiency.At the same time it compared the results of UV/TiO_2/micro-O_3 with the results of UV/O_3,UV/TiO_2/air and UV/TiO_2/O_3.The results showed that UV/TiO_2/air had a lowest efficiency,after 2 h treatment, the removal efficiency of UV/TiO_2/micro-O_3 is more than 70%,quite close to the result of O_3 photocatalytic oxidation. |
