浙江沿海某石油化工类企业地下水污染特征

Pollution Characteristics of Groundwater from Petrochemical Enterprise in Coastal Area of Zhejiang Province

以浙江沿海面积约36 km2的某石化场地为研究区域,开展了地下水污染调查、评价和综合研究,结果表明,该石化场地地下水(0 m～5 m)存在重金属、硫化物、石油类等污染,污染范围主要在老厂区和滩涂堆填区,其分布特征受到上层填土和工业企业活动等人类活动的影响,也与区域环境水文地质条件密切相关。

A synthetic study containing investigation and assessment of groundwater pollution was carried out in a coastal petrochemical field with an area of 36 km2 in Zhejiang Province.The results indicate that pollutants such as benzene series substance,heavy metals,petroleum,and sulphide were found in the groundwater（0~5 meters in depth） under the field of majority of old factories and wetland landfills.The distribution of pollutants are impacted by human activities of soil filling form upper stratum and activities from industrial enterprises,as well as hydrological and geological conditions of the area.
