| 摘 要： | 以稠油为唯一碳源，对细菌B0501、B0505和B0510的降解特性进行了分析，结果表明3株菌对稠油的不同组分具有不同程度的降解能力，其中B0505对烷烃、B0510对芳香烃以及B0501对胶质和沥青质的去除率较高，分别为42.26%、35.30%和40.76%；混合菌协同作用强化了稠油组分的降解，3株菌株组合对烷烃、芳香烃以及胶质沥青质的降解率分别达到44.23%、38.56%和62.12%；微生物对稠油降解过程符合一级动力学方程，其中3株菌株组合对稠油降解的速率最快，半衰期(t1/2)为5.36 d。将微生物应用于稠油废水处理实践，结果表明外源微生物的投加强化了废水中COD的去除率；GC-MS图谱及降解前后有机成分分析进一步佐证了微生物对稠油废水中有机成分的降解能力。

| Abstract: | Degrading characteristics of bacteria B0501,B0505 and B0510 with viscous oil as the sole carbon source were investigated.The experimental results show that different components have different degrees of degradation by the three different bacteria.And the degradation rates of alkyl hydrocarbon by B0505,that of aromatic hydrocarbon by B0510 and that of pectin and aliphatic hydrocarbon by B0501 are higher,which are 42.26%,35.30% and 40.76%,respectively.Mixed bacteria enhance the degradation of oily component b... |
