污染场地中挥发性有机污染工程修复技术及应用

Engineering Remediation Techniques and Its Application for Volatile Organic Compounds-contaminated Sites

  • 摘要: 工业企业环保搬迁后遗留的大量污染场地的修复面临着严峻挑战,其中尤以挥发性有机物遗留污染场地为甚。国外关于挥发性有机物的工程修复技术已较为成熟,且应用广泛,但国内场地工程修复案例较少,且依据于各地经济社会水平的修复技术筛选问题仍是制约我国污染场地修复的主要瓶颈。因此,为推动挥发性有机物工程修复技术在我国污染场地修复中的应用,介绍了挥发性有机物工程修复技术的主要类型及原理,并就其技术本身、修复周期、费用等方面进行比较;结合美国超级基金项目中近30年来的应用情况,探讨各种工程修复技术的工程应用及其发展趋势。

     

    Abstract: It is a big challenge to remediate the left contaminated sites which caused by the relocation of so many factories and companies, especially for the volatile organic compounds (VOCs)-contaminated sites. The engineering remediation techniques (ERTs), being relatively mature, have been widely used in foreign contaminated sites. However, there are few cases in China. It is still a challenge for those who remediate the contaminated sites to select the best available techniques based on their own economic and social development levels. In order to promote the application of ERTs in the contaminated sites of China, the major types and the technical principles of ERTs for VOCs were reviewed, and the technologies contents, remediation periods and costs compared. The engineering applications and development trends of various ERTs for VOCs were discussed, combined with the applications in US superfund sites in nearly 30 years.
