石油污染土壤修复技术应用现状

The Application Status in Remediation of Petroleum Contaminated Soil

石油开采、贮存及运输过程中泄漏事故屡有发生,对受其污染的土壤进行有效治理成为社会关注的焦点。本文介绍了石油污染问题及物理、化学、生物治理方法,着重介绍了微生物修复技术的分类及应用现状,探讨了降解微生物筛选和定植、石油烃生物可利用度改善等制约生物修复效果的关键因素。

In the process of oil production,storage and transportation,oil leakage accidents happened frequently. How to control the pollution of environment effectively had increased a lot of attentions. This article presented the situation of soil pollution by petroleum and some traditional remediation methods including physical, chemical and biological treatment methods. The classification and application of microbial remediation technology was introduced. The article pointed out that isolation,colonization of degrading bacteria and improving the biological availability of petroleum hydrocarbon were the key factors for bioremediation.
