| 摘 要： | 针对某化工厂污染场地的修复问题,采用土壤气相抽提原位修复技术将包气带中的挥发性和某些半挥发性污染物抽出,使污染场地得以修复。根据场地条件及污染特性,确定修复系统的组成、运行。样品检测结果表明:修复8个月后,对主要污染物苯,在土壤中的去除率达95.2%~99.9%,在土壤有机废气中的去除率达80.7%。从实际工程应用说明土壤气相抽提技术是一种效果较好的修复技术,为类似污染场地原位修复问题提供工程技术参考。

| Abstract: | To remedy the contaminated site occurred in a chemical plant,soil vapor extraction technology was used to extract volatile and some semivolatile contaminants in vadose zone soils and thus the site could be remedied.The remedial system and its application based on the site environmental conditions and pollutant was introduced.The results showed that 8 months after remedy,95.2%~99.9% benzene in soil and 80.7% in volatile organic compound were removed.The project indicated that soil vapor extraction is an effi... |
