摘要:

        为修复陕北黄土区石油污染地下水,采用优化土著微生物菌群的生物技术,进行了地下水中石油的降解与修复实验研究。在实验装置内加入了1.5%的优化菌群制剂,优化出的菌群初步鉴定主要有:假单胞菌属、微球菌属、放线菌属、真菌类的青霉属和曲霉属等。实验结果显示,在实验装置中人为添加石油含量为182.5 mg/l、862.5 mg/l、1 695.0 mg/l时,经过28~37 d的微生物修复,地下水中石油的降解率为27.47%~92.46%, 而无菌对照中的石油含量变化在5%以内,说明在无菌条件下地下水中石油降解缓慢。该实验过程验证了微生物修复技术在地下水石油污染修复中的有效性,探索了应用的可行性。

Abstract:

     In order to remediate oil contaminated groundwater in loess region of North Shaanxi Province, microbial techniques of optimized native microbial communities were used for experimental studies on oil polluted groundwater remediation. In this experiment, 1.5% optimized microbial populations were added. The optimized microbial populations were primarily identified as Pseudomonas, Micrococcus, Actinomayces, Penicillium and Aspergillus. The results of the experiment showed that the oil, with contents of 182.5 mg/l, 862.5 mg/l and 1,695.0 mg/l, added artificially into soil can be reduced by 27.47% to 92.46% after enhanced microbial remediation for 28 to 37 days, whereas the oil degradation rate in non-bacterium reference sample was less than 5%, which suggests that the oil degradation in groundwater with non-bacterium was slow. This experiment demonstrated the effectiveness of microbial remediation techniques for oil contaminated groundwater, and explored the feasibility of the technique application.  
