| 摘 要： | 本研究从长期被焦化废水污染的污泥中分离出一株优势短杆菌研究该菌株及其在无机离子存在下对蒽、菲、芘的降解性能.结果发现该菌株对蒽、菲、芘均有良好的降解效果,Fe3+对降解过程有促进作用,反应10h后,蒽、菲、芘转化率分别可达约75%,87%,及62%.总有机碳(TOC)的测定结果表明,该菌株在106h内能分别将反应瓶中加入的蒽、菲、芘所产生的总有机碳去除50%、90%及50%.

| Abstract: | A preponderant brevibacterium was isolated from the sludge contaminated by coke plantwaste water for a long time. The bacterium was effective on the degradation and transformation of anthracene, phenanthrene and pyrene. The degradation process can be accelerated by ferric ions. 10 hours after aeration, the removing rates of anthracene, phenanthrene and pyrene by the brevibacterium were about 75%, 87% and 62% respectively. 106 hours after aeration, the removing rates of total organic carbon (TOC) caused by anthracene, phenanthrene and pyrene were 50%, 90%, and 50% respectively. |
