Abstract

The kinetic study of the ozonation of atrazine as a single contaminant characterized as COD was studied. A jet loop ejector reactor was used to improve the mixing and transfer of ozone in the reaction system. The results show a higher efficiency of atrazine degradation in alkaline pH during the first 45 minutes. At the same time, the dechlorination of atrazine is faster than in neutral pH. Respirometric measurements carried out with activated sludge were used to evaluate the effect of atrazine and the ozonation intermediates on microorganisms’ oxygen uptake rate. The results showed that ozonation performed at an alkaline pH resulted in the formation of substances that are more rapidly biodegradable compared to substances formed by ozonation at neutral pH, as well as compared to atrazine.

阿特拉津臭氧氧化动力学研究

研究了以 COD 为特征的单一污染物阿特拉津的臭氧氧化动力学。采用了喷射环喷射器反应器来改善臭氧在反应系统中的混合和转移。结果表明，在碱性 pH 值条件下，前 45 分钟的阿特拉津降解效率较高。同时，与中性 pH 值相比，阿特拉津的脱氯速度更快。利用活性污泥进行的呼吸测定法评估了阿特拉津和臭氧中间产物对微生物摄氧量的影响。结果表明，在碱性 pH 值下进行臭氧处理形成的物质与在中性 pH 值下进行臭氧处理形成的物质相比，生物降解速度更快，与阿特拉津相比也是如此。
