锦州市典型工业污染源地下水基础环境调查与评估

Investigation and Assessment on Basic Environment of Groundwater of Typical Industrial Pollution Sources of Jinzhou

通过污染源筛选,采用对照区、污染区、清洁区优化的控制性布点与功能性布点方法,对典型工业污染源锦州石化分公司周边地下水基础环境状况进行调查和监测,掌握了背景、常规、特征污染因子污染状况及污染物分布时空规律,监测结果显示,除亚硝酸盐、阴离子洗涤剂等个别生活类污染因子和石油类超标外,其余监测因子均达标。石化行业特征因子石油类所有点位全部超标,说明锦州石化分公司已对周边地下水造成污染扩散影响。

Adopting the method of pollution source screening and controlled stationing and functional stationing of optimizing the Control area,pollution area and cleaning area,the basic environment of groundwater in Jinzhou petrochemical company was investigated and supervised.Got the background,routine,characteristics of pollution factors and the spatial and temporal rule of pollutant distribution.The results show that the remaining monitoring factors are up to standard,except for the oil-related factors and some pollution factors in our daily life such as nitrite,anionic detergent and so on.All petroleum points in the characteristics of petrochemical industry are out of limits,which indicates Jinzhou petrochemical branch has affected the surrounding groundwater.
