摘要
为了考察生化法代替部分臭氧氧化的可能,对菲进行了臭氧不完全氧化研究.采用液相色谱和紫外光谱观察了氧化过程和中间产物的变化,并且测定了中间产物水溶液的总有机碳浓度(TOC)和中间产物对活性污泥氧吸收速率(OUR)的影响.结果表明,菲被臭氧氧化的同时,有中间产物生成;臭氧可以与中间产物反应,但是难以使之矿化;臭氧氧化改善了菲的可生化性.臭氧氧化结合生物降解,有望成为兼顾经济性与效率的处理废水中菲的方法.
In order to investigate the feasibility of taking biochemical technique instead of partial ozone oxidation, the partial ozone oxidation of phenanthrene （Phe） was made. The oxidation process and the intermediate products changes were observed using HPLC and UV; and the influences of the TOC of aqueous solution of intermediate products and these products on oxygen uptake rate（OUR） of activated sludge were examined. Intermediate products were produced at the same time when the ozone was oxidized by phenanthrene, the ozone could react with these intermediate products; but difficult to mineralize it. However, the ozone oxidation could improve the biochemical property of phenanthrene. Therefore, the combination of ozone oxidation with biodegradation would be a potentially efficient and economical way to treat phenanthrenc in wastewater.
