摘    要:对生物柴油促进原油污染砂砾释放油的效果进行了研究,并探讨了原油中3种芳香烃的释放情况,以及在微生物的作用下这3种芳香烃的降解情况.结果表明:生物柴油的促进效果随着投加量的增加而升高,当投加量为原油总质量的1/5时,促进原油总量释放效果不再明显增加,释放量达到80%,并且环数较少的多环芳烃释放量大;该微生物对芳香烃的降解顺序是从低环到高环,并且对4环的芳香烃降解效果不明显.

关 键 词:石油污染  多环芳烃  生物柴油  微生物  释放  气相色谱

Abstract:This paper makes a study of the promotive effects on biodiesel release oil from crude oil contaminated sand and explores the three kinds of aromatic hydrocarbons release from crude oil contaminated sand and the degradation of the three aromatic hydrocarbons un- der the action of microorganisms. The results show that the biodiesel promoting effect with the increase of dosing quantity increases,when dosing quantity for 1/5 of the total crude oil quality of promoting total crude oil release effects no longer significantly increases, release quantity achieves 80%,and the number of less ring PAHs releasing capacity. Microbial deg- radation of the order of aromatic hydrocarbons from low ring to high ring, and the 4-rings degradation of aromatic hydrocarbons effect is not obvious.
Keywords:petroleum contamination  PAHs  biodiesel  microbial  release  gas chromatography
