【摘要】 对含油质量分数为9.0%和10.2%的油泥进行生物地耕法的研究。结果表明,生物降解120d后,油泥残油质量分数分别由9.0%和10.2%降至3.1%和4.0%,石油降解率分别为65.6%和60.8%;同时利用气相色谱-质谱分析生物降解前后含油污泥中饱和烃的组分和质量分数变化,含油质量分数为9.0%和10.2%油泥中的长链烷烃分别减少39.8%和42.2%。更多还原

【Abstract】 The two oily sludges that with 9.0% and 10.2% oil content were remediated by using the land-farming method.The results show that after 120 days of biodegradation,the oil content decreased to 3.1% from 9.0% and to 4.0% from 10.2%,petroleum degradation rates can reach 65.6% and 60.8% respectively.The saturated hydrocarbon components and relative content before and after biological treatment were analyzed by gas chromatography-mass spectrometry.The long-chain alkanes in 9.0% and 10.2% oil samples are reduced by 39.8% and 42.2% respectively.更多还原
