Application of in-situ ectopic pile thermal desorption technology and equipment in the petroleum-contaminated soil remediation

利用杰瑞环保科技有限公司自主研发生产的原地异位建堆热脱附设备对新疆某地区506 t石油污染土壤进行了修复处理实验,并在此基础上探讨了原地异位建堆热脱附技术在石油污染土壤修复领域应用的相关技术问题。通过温度场模拟,为设备投入及修复堆体的搭建提供了参考数据;通过项目现场温升曲线,分析了升温效率与物料属性的关系。结果表明,含水率越低的物料升温速率越快。此外,通过对设备投入、石油污染土壤修复效果、修复过程运行能耗等方面进行综合分析,评估了原地异位建堆热脱附技术在石油污染土壤修复领域的有效性和实用性。本研究可为原地异位建堆热脱附技术在石油污染土壤修复领域的工业化应用提供参考。

An independent developed in-situ ectopic pile thermal desorption equipment by Jereh was used to remediate 506 t petroleum-contaminated soil in Xinjiang,then the application of in-situ ectopic pile thermal desorption technology on the remediation of petroleum-contaminated soil was explored.From the simulation of temperature field,the theoretical guidance for the equipment investment and remediation pile construction was provided.According to the temperature curves of the project,the relationship between the heating efficiency and material properties was analyzed.The results showed that faster heating rate occurred for the material with lower moisture content.In addition,multiple factors such as equipment investment,petroleum-contaminated soil restoration effect and energy consumption were analyzed to evaluate the effectiveness and practicability of insitu ectopic pile thermal desorption technology in the remediation of petroleum-contaminated soil.Through the comprehensive evaluation of above aspects,this study could provide a reference for the industrial application of the in-situ ectopic pile thermal desorption technology in the petroleum-contaminated soil remediation.
