采用臭氧氧化技术处理给水系统中难降解的诺氟沙星(NOR),考察了NOR臭氧氧化的影响因素,得出最佳的处理条件:初始pH为8,臭氧投加量为5 mg/L,反应90 min后去除效率达31.02%,较常规处理大大提高,同时还对反应机理进行了初步探索,研究表明,NOR经臭氧氧化后生成多种小分子物质。
The treatment of norfloxacin by ozonation process was studied.The effects of O3 dosage,initial solution pH and initial concentration of the norfloxacin on the efficiency of the process were also investigated.It was found that the optimum conditions were as follows: initial pH value of 8;O3 dosage of 5 mg/L.After continuous treatment about 90 minutes,the removal rate is 31.02%,higher than regular treatment.The reaction mechanism was also explored.The results show that O3 will oxidize norfloxacin to several minor molecule substances.
