摘要:

利用本源微生物对受石油污染土壤进行了生物修复的室内试验。研究表明，在添加双氧水电子受体和适量的营养盐后，75天内土壤中石油烃的去除率可达到62．5％；添加表面活性剂可以促进微生物对石油烃的生物降解，在添加0．05％（ω）的吐温一40后，75天内土壤中的石油烃去除率可由62．5％提高到了88．6％。试验证明对含油土壤进行生物修复是可行的。

Abstract:

The bioremediation of oil-contaminated soil by aboriginal microorganism was carried out in the laboratory scale.The research indicated that, after adding hydrogen peroxide electron acceptor and right amount of nutrition, the petroleum hydrocarbon in soil
