石油烃是土壤修复场地中重点关注的有机污染物,存在高毒性和持久性.本文以上海普陀区实际土壤修复项目中的深层、高浓度石油烃污染土的氧化修复为案例,讨论了深基坑开挖的风险、应对技术,并通过小试探究了以过硫酸钠、生石灰为代表的高级氧化体系对石油烃的修复效果,小试及中试试验证明,在1%过硫酸钠及1%生石灰的投加量条件下,石油烃污染物的去除率可达到76%.本研究明确了实际大体量石油烃土壤修复过程中的氧化剂及激活剂的有效投加量,补充现有的工程应用数据,为后续相关修复项目提供参考.
Activated Persulfate Oxidation Treatment of High Concentration Total Petroleum Hydrocarbon Pollution in A Deep Excavation Soil
Petroleum hydrocarbons are organic pollutants of major concern in soil remediation sites,knows for their high toxicity and persistence.This article takes the deep-layer,high-concentration petroleum hydrocarbon-contaminated soil remediation project in Putuo Dist.,Shanghai as a case study to discuss the risks and response techniques associated with deep excavation.It also conducts preliminary experiments to explore the remediation effect of advanced oxidation systems represented by sodium persulfate and quicklime on petroleum hydrocarbons.The experimental results showed that the removal rate of petroleum hydrocarbon was 76%with 1%sodium persulfate and 1%quick lime.The study aims to determine the effective dosage for large-scale remediation processes and supplement existing engineering application data,providing reference for subsequent related remediation projects.
