石化场地土壤与地下水污染防控研究进展

Research progress of soil and groundwater environment conservation for petrochemical site

通过分析石化场地水文地质、企业生产、周边环境特点,对华北、西北、华东、华中四个石化场地调查表明,场地潜在污染主要为石油烃、苯系物、挥发性有机物、多环芳烃等,并研究污染物在土壤与地下水中分布特征与迁移规律,剖析石化场地污染预防、控制与治理技术,提出加强场地监测,科学制定管控与修复目标,强化污染控制与修复过程组织管理的建议,确保大型石化场地的安全利用。

Analyze the hydrogeology,enterprise production,and surrounding environment characteristics of petrochemical sites,surveys of four petrochemical sites in North China,Northwest China,East China,and Central China show that the potential pollution of the site is mainly petroleum hydrocarbons,benzenes,volatile organic compounds,and polycyclic aromatic hydrocarbons.Investigate the distribution characteristics and migration principles of pollutants in soil and groundwater,analyze the pollution prevention,control and remediation technologies of petrochemical sites.Suggestions are put forward for strengthening site monitoring,scientifically setting control and remediation goals,and strengthening the organization and management of pollution control and remediation processes to ensure safety utilize of large-scale petrochemical sites.
