摘要
采用臭氧氧化技术处理给水系统中难降解的卡马西平,考察了卡马西平臭氧氧化的影响因素,得出最佳的处理条件:初始pH为6.7～6.9,臭氧投加量为1 mg·L-1,反应40 min后去除效率达43.49%,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CBZ经臭氧化后生成二苯乙腈和多种小分子物质。
The treatment ofcarbamazepine by ozonization process was studied. Under the condition, the effects of O3 dosage, initial solution pH and initial concentration of the carbamazepine on the efficiency of the process were also investigated. It was found that the optimum conditions were as follows： initial pH value, 6.7-6.9; O3 dosage, 1mg.L^-1. After continuous retreatment about 40 minutes, the removal rate was 43.49%, higher than regular treatment. The reaction mechanism was also explored. The results showed that O3 will oxidize carbamazepine to several minor molecule substances.
