摘要
本文运用气相色谱法,对渤海微生物自然混合菌群降解20号重柴油中的烷烃的能力进行了实验室研究。实验测定了在5,50,500ppm三个油浓度下微生物自然混合菌群对正烷烃的降解能力。20天内,微生物对正烷烃(C_(11)—C_(22))的生物降解率分别为56.63%,61.45%和72.36%;物理化学降解率分别为34.18%,38.18%和19.85%。正烷烃的总降解率分别为90.81%,99.63%和92.21%。在本实验条件下,经过20天的降解,20号重柴油中的C_(11)—C_(22)烷烃绝大部分被降解。
An experiment was conducted using gas chromatography to study the n-alkanes in No.20 diesel oil,which was degraded by the natural strains of microorganisms from the Bohai Sea.The experiment has proved that the gas chromatography is rapid and effective for checking the n-alkanes’change due to the petroleum biological degradation.The oil-degradation of the n-alkanes by the natural strains of microorganisms was determined at 5,50,500 ppm diesel oil in 20 days of incubation,the bio-degradation rates of the n-alkanes were 56.63%,61.45%and 72.36%;the physical and chemical decomposition rates were 34.18%,38.18%and 19.85%;and the total degradation rates of the n-alkanes were 90.81%,99.63%and 92.21%respectively,at the three different diesel oil concentration.It was clear under the experimental conditions that the n-alkanes(C_(11)-C_(22))in the No.20 diesel oil could by mostly degraded.During the experiment,a better relation between the content of the n-alkanes and the numbers of the oil-degrading bacteria and fungi existed.
