石油生产运输中污染土壤修复技术研究

Remediation technology of contaminated soil in petroleum production and transportation

石油钻井开采及储运过程中,井喷、洗井或漏失都会造成高矿化度废水或原油洒落地面,对周围土壤造成石油污染、盐渍化或者微量重金属污染。本文综述了几种应用于石油生产运输中的污染土壤修复技术,分析了其优缺点及研究进展,包括物理修复、化学修复、生物修复和联合修复,并对应用于石油生产运输方面的土壤修复技术的发展趋势进行了展望。

In the process of petroleum production and transportation, well blowout, washing or leakage will cause high waste salinity water or crude oil spill on the ground, causing oil pollution, salinization or trace heavy metal pollution to the surrounding soil. In this paper, several remediation technologies tbr contaminated soil used in oil production and transportation was reviewed. Their advantages, disadvantages and research progress are analyzed, including physical remediation, chemical remediation, bioremediation and combined remediation, and the develop- ment trend of soil remediation technology applied to oil production and transportation is prospected.
