中原石油污染土壤原位微生物生态修复技术的应用

摘要

The field remediation of the oil residue pollution in soil were carried out in Zhongyuan Oil Field, which using the optimistic techniques of in-situ microbial communities combining with the physical and chemistrial methods. The results showed that degradation rate can reach 99％ as the oil content of 2 898.25 mg/kg in polluted soil after 99 d microbial and ecological remediation, which provide us the feasible technology and application of oil residue pollution remediation in soil at oilfields.%利用优化原位土著微生物菌群辅以物理和化学相结合的生态修复技术,进行了河南中原油田石油残留污染土壤的野外修复应用研究.修复结果显示,土壤中残留石油含量平均在2 898.25 mg/kg时,经过99 d微生物生态修复技术的实施,土壤中石油含量降解可达99%以上,为油田区土壤石油残留污染的修复提供了技术方法和推广应用的可行性研究.
