摘  要:
采用臭氧氧化法处理直接紫染料废水,考察了反应时间、臭氧投加量和初始pH等条件下臭氧氧化过程对废水COD和色度去除率的影响。结果表明,臭氧氧化过程中COD去除率随着臭氧投加量的增加而增强,随着反应时间和初始pH的增加先增大后减小;色度的去除率随着臭氧投加量和反应时间的增加而增加,随着初始pH的增加先增加后略有减小。当初始pH为10、臭氧投加量为35μg/L、处理7 min时,COD去除率达92.8%,色度去除率可达98.3%,污水处理效果最佳。

摘  要:
Direct violet dyeing wastwater was treated by ozonation process.Effects of reaction time,dosage of ozone,and original pH on COD and color removal rate were investigated.The results indicated that during the ozonation process,COD removal rate increased with the increasing of ozone dosage,and increased firstly and then reduced with the increasing of reaction time and original pH;color removal rate increased with the increasing of ozone dosage and reaction time,increased firstly and then declined slightly with the increase of original pH.When initial pH was 10,dosage of ozone at 35 μg/L and ozonation reaction time for 7 min,the removal rate of COD and color was 92.8% and 98.3%,respectively.
