摘要
由输油管道破损泄露导致的土壤石油污染问题越来越引起人们的关注,本文针对管输油品泄露的土壤污染治理,首先介绍了常用的传统物化治理技术并进行其优缺点分析,着重对修复效果迅速,二次污染较小的化学修复技术中的表面活性剂淋洗技术和芬顿氧化降解技术的修复机理、研究进展、不足及发展展望进行探讨。建议对重度石油污染土壤以表面活性剂淋洗技术或芬顿氧化技术进行初步清理以去除大部污染物,而后综合应用生物治理技术进行修复以缩减治理时间,提高治理效率,并开发新型低成本、高效环保的处理剂促进土壤石油污染治理的工业大规模化应用。
The problem of soil petroleum pollution caused by pipeline breakage and leakage has attracted more and more people’s attention.In view of the treatment of soil pollution caused by pipeline oil leakage,this paper firstly introduces the conventional physical and chemical treatment technology and analyzes its advantages and disadvantages,focusing on the chemical remediation technology with quick remediation effect and less secondary pollution.The remediation mechanism,research progress,shortcomings and development prospects of Surfactant Elution and Fenton oxidation degradation were discussed.It is suggested that surfactant leaching technology or Fenton oxidation technology should be used to remove most of the pollutants in the heavily petroleum-contaminated soils,and then bioremediation technology should be applied to reduce the treatment time and improve the treatment efficiency,and a new type of low-cost,high-efficiency and environmentally friendly treatment agent should be developed to promote soil petroleum pollution.The large-scale industrial application of governance.
