龙湾区某场地铅污染土壤的稳定化工程应用及技术研究

通过对温州市龙湾区2个重金属污染地块的治理效果比较,介绍一种稳定、高效、安全的场地治理技术。通过添加1%碱性钙基稳定剂和标准化施工流程,在铅污染超标的土壤治理工程中取得较好效果。结果表明,该稳定化技术受龙湾区本地气象因素影响较小,能明显降低土壤中铅的危害性,并兼顾了治理周期和成本,为温州地区同类工程积累了本地数据。

By comparing the remediation effects of two heavy metal contaminated sites in Longwan District of Wenzhou,this paper introduces a stable,efficient and secure site remediation technology.This soil remediation projects with excessive lead was successful by adding 1%alkaline calcium-based stabilizer and standardized construction process.The stabilization technology is less affected by climate,and the harmfulness of lead is obviously reduced.At the same time,this technology shortens the period of remediation and reduces the governance funds.Accumulated local data for similar remediation work in Wenzhou area.
