| 摘 要： | 研究不同条件下臭氧对偶氮染料酸性黑ATT废水的降解效果。实验表明:(1)对于某种浓度的臭氧,在一定的接触反应时间范围内,化学需氧量(COD)去除率随接触反应时间增加而增加;(2)增加臭氧浓度可提高降解反应速度,减少反应时间;(3)在酸性条件下臭氧对降解酸性黑ATT废水没有明显促进作用.而在碱性条件下臭氧可以提高降解反应速度。

| Abstract: | Degradation efficiencies of wastewater of,Acid Black ATT by ozone under different conditions were investi- gated.The results are as follows:For ozone with a certain concentration,removal of chemical oxygen demand (COD) increases along with contact time within a certain range;The degradation speed increases by increasing the concentra- tion of ozoneas well as reduction of reaction time;Degradation efficiency of wastewater of Acid Black ATT by ozone can't been affected by acidic conditions.In contrast,the rate of degradation reaction increases under alkaline. |
