| 摘 要： | 对蒽进行了臭氧不完全氧化实验研究,利用HPLC、UV、TOC监测了臭氧氧化过程中发生的变化.结果表明,蒽被臭氧降解时有中间产物生成,臭氧可以与中间产物继续作用,但是难以使之矿化.另外,氧化体系中水溶性有机物的TOC变化及其对活性污泥OUR的影响结果表明,臭氧氧化改善了蒽的可生化降解性.因此,臭氧氧化与生物降解组合技术,有望成为处理废水中蒽的经济有效方法.

| Abstract: | Partial ozonation of anthracene was carried out. Ozonation process and changes of intermediate products were examined with HPLC and UV. TOC of soluble organics of ozonized products and oxygen uptake rate(OUR) of activated sludge which showed the influence of these organic compounds were also examined. The results indicated that during the ozonation process, anthracene was degraded, and new organic compounds were produced. Ozone could react further with these intermediate products, but could not mineralize them. However, biodegradability of anthracene was improved by ozonation. Therefore, the combination with ozonation and biodegradation would be possible an efficient and economical way to mineralize anthracene in wastewater. |
