| 为了探讨生物刺激、生物强化及其联合体系对石油污染物的去除能力,选择最佳的修复策略,更好地发挥微生物修复的优势.以一株蜡状芽孢杆菌石油降解菌为例,以有机营养物、无机营养物和混合营养物为底物,进行生物刺激、生物强化试验及联合降解试验.结果显示,不同修复方式在不同时段的降解效果不同,生物刺激方式在第5天时混合营养物降解效果最好,降解率达到40.98%,在10 d不同营养物的降解率存在明显的差距,而在处理20 d后,降解率基本一致,达到80%.生物强化的处理结果中,以混合营养物为底物时,表现出了优异的降解效果,降解率达到90.23%.研究表明:不同时期不同的修复策略有表现出了对原油的不同去除能力,也为实践中选择合理的修复方式提供科学的理论指导. |

| In order to investigate the removal ability of biological stimulation,biological enhancement and its combined system to remove petroleum pollutants,the best repair strategy was chosen to better utilize the advantages of microbial remediation.Taking an oil degrading Bacillus cereus as an example,the biological stimulation,biological enhancement test and combined degradation test were carried out on the basis of organic nutrients,inorganic nutrients and mixed nutrients.Different repair methods in different periods had different degradation effect,and the biological stimulation had the best degradation effect on the fifth day when the degradation rate of the mixed nurients reached 40.98%,on the 10th day the degradation rate of different nurients had obvious differences,and on the 20th day,the degradation rate reached 80% which was consistent.In the treatment of bioaugmentation,when mixed nutrients were used as substrates,the degradation rate was excellent,and the degradation rate was 90.23%.Different periods and different repair strategies showed different removal ability of crude oil,which provided some theoretical significance for selecting reasonable repair methods in practice. |
