摘　　要：苯系物具有"致癌、致畸和致突变"特点,其在生产、运输和储存过程中极易进入地下水环境,因此地下水体中苯污染是当前世界许多国家尤其是经济高速发展国家面临的重要环境和社会问题之一。文章以石化工业污染场地为研究对象,提出苯污染的修复思路和关键环节,即通过分析苯系物迁移转化规律,以时间、成本及污染程度构建修复概念模型,筛选合理修复技术完成修复目标。选择我国某加油站典型案例为分析对象,综合研究浅层地下水苯污染调查及修复技术应用进展和问题,并提出对我国污染修复的技术政策建议。BTEX are proved to be carcinogenic, teratogenetic and mutagenic and consequently endanger human＇s health by contaminating underground water during the periods of production, transportation and storage. Therefore, groundwater pollution by benzene is one of the major environmental and social problems confronted by many countries, especially those with quick economic growth. In this paper, petrochemical industrial sites are taken as the study targets and ideas and key links for benzene pollution remediation are proposed. That is, migration and transformation rules of BTEX are analyzed; repair concept model on time, cost and pollution degree is built up; and reasonable remediation technology is screened out to fulfil the remediation target. Typical cases of a gas station in China are selected for analysis. Survey of shallow groundwater pollution by benzene and application of remediation technologies and problems are studied in a comprehensive way. Then, technical and policy suggestions are put forewords for pollution remediation in China.
