摘　　要：采用联合使用毛细管气相色谱法和紫外可见分光光度法,系统地研究了一种混合微生物体系对柴油的降解过程。研究结果表明,这两种简单方法的简单组合,弥补了单一方法的局限性,能够监测石油烃类污染物总体和主要组分的降解程度,实现对烷烃和芳香烃降解的分别评价。同时还表明,本实验采用的混合微生物体系对柴油具有很强的降解能力。Biodegradation of diesel in the presence of mixed microorganism consortium was studied by gas chromatography and ultraviolet spectrophotometry in aqueous solutions. It is shown that the combination of the two simple analytical techniques remedies the shortage of the single One, and that the combination is successfully used to monitor the biodegradation efficiency of diesel and its primary components, and to evaluate separately the degradation of linear alkanes and aromatic hydrocarbons components. The experimental results further demonstrate that the mixed microorganism consortium can degrade diesel in aqueous solutions efficiently, achieving a removal of about 80% over five days.
