微生物菌剂对石油污染土壤的修复研究
Remediation of petroleum contaminated soil by bacterium microbial agent
摘要
Abstract
Soil salinization and petroleum contamination are dual problems around oil field. The petroleum contaminated soil remedying experiments were performed in Shengli Oil Field using some measures, such as irrigation for salt-leaching, soil tillage, addition bacterial agent and nutrient. The changes of water-soluble salts,microorganism, dehydrogenase, petroleum concentration were detected during remediation process. The results showed that there was a correlation among microorganism and dehydrogenase and petroleum degradation. All the three factors kept at high levels at the early. But after then, the number of microorganism reduced, the activity of dehydrogenase decreased, meanwhile the petroleum biodegradation rate declined. Indigenous microorganisms,inoculated microbiological, soil permeability all played an important role during remediation process. After two month of remediation, about 67.7% of petroleum in the contaminated soil were degraded.关键词
