摘要
工业化快速发展导致地下水污染问题日益突出,地下水污染调查评价是了解地下水质量状况、污染来源、污染范围和污染程度的基础工作.选取华北某石化企业为研究对象,采用单指标评价法开展地下水取样测试分析,发现石油类、石油烃、溶解性总固体、铁、氨氮、钠、镉、铅等因子超出相应的标准限值.结合生产工艺及原辅材料分析,推测超标现象与该场地所在企业前期生产活动有关.该研究为调查企业的污染管控提供了数据支撑,亦可为类似石化场地的调查评价提供参考.
Abstract
With the rapid development of industriali-zation,the problem of groundwater pollution has be-come increasingly prominent. The investigation and evaluation of groundwater pollution is the basic work to understand the status of groundwater quality,pol-lution sources,pollution scope and pollution degree. A petrochemical enterprise in North China was select-ed as the research object,and the groundwater sam-pling analysis was carried out by single index evalua-tion method. It was found that petroleum,petroleum hydrocarbons,dissolved total solids,iron,ammonia nitrogen,sodium,cadmium,lead and other factors exceeded the corresponding standard limits. Com-bined with the analysis of production technology and raw and auxiliary materials,it was speculated that the phenomenon of exceeding the standard was related to the early production activities of the enterprises loca-ted in the site. This study provided data support for the pollution control of the investigation enterprises,and also provided reference for the investigation and evaluation of similar petrochemical sites.
