摘要: 随着石油化工行业的快速发展,石化企业生产的产品在其储运及处置过程中存在“跑、冒、滴、漏”现象,导致污染物渗入土壤及地下水,可能造成场地污染。以某炼化污水处理场地为研究对象,在综合分析已有资料的基础上,通过水文地质勘察、土壤地下水样品采集分析,判断场地污染物种类为石油烃、1,1,2-三氯乙烷、1,2,3-三氯丙烷和苯并[a]芘。采用GMS和SURFER软件模拟手段,构建污染地层介质及特征污染空间三维可视化模型,明确了场地内地层岩性复杂,填筑土、粉质黏土及圆砾受到不同程度的污染,且污染羽沿地下水流场方向延伸。综合分析了地层介质对污染物迁移的作用,为污染风险评价、污染防控及修复提供了依据。

Abstract: With the rapid development of petrochemical industry, petrochemical pollutants from production process due to leakage, maintenance, accidents can penetrate into soil and ground water, and cause the contaminate of soil and ground water. Based on the comprehensive analysis of the existing data, the types of pollutants on the site were determined to be petroleum hydrocarbon 1,1,2-trichloroethane, 1,2,3-Trichloropropane and benzo[a] pyrene. By means of GMS and SURFER software simulation, a three-dimensional visualization model of polluted stratum media and characteristic pollution space was constructed. The results showed that the filling soil, silty clay and pebbles were polluted to different degrees, and the pollution plume extends along the direction of ground water flow field. The effects of lithology conditions on pollutant migration were comprehensively analyzed, which provided basis for pollution risk assessment, pollution prevention and remediation.
