污染场地修复过程中挥发性有机物(VOCs)污染研究进展

Advances in the Study on Secondary Pollution of Volatile Organic Compounds in Remediation of Contaminated Sites

近年来,我国污染场地修复工程项目数量快速增长,其中农药化工类污染场地修复过程中的空气二次污染问题受到广泛关注。针对污染场地修复施工过程中存在的挥发性有机物(VOCs)污染来源,提出科学有效的施工过程管理是切断二次污染排放源进入空气途径的主要手段,分析了我国现有施工管理技术与监管方面的不足,并对国内相关的监管措施与研究进展进行了回顾。

In recent years, the number of engineering projects for remediation of contaminated sites in China has been in-creasing rapidly. During implementation of these projects, the issue of secondary air pollution occurring in remedying pesti-cide chemicals polluted sites is attracting more and more concerns. Sources of VOCs in remediation of contaminated sites were analyzed, and scientific efficient management of the remediation projects was put forward as the major means to block the source of secondary air pollution from releasing pollutants into the air. Shortcomings in implementation and management of these projects in the country were also analyzed. Advancements in the study on and management measures of the issue in China and other countries were reviewed.
