石化项目地下水保护措施有效性分析

石化产品在储运过程中若发生污染事故,污染物会通过包气带渗入到地下水中,对地下水质量产生影响。通过预测,制定科学的地下水防治措施,是防止项目对地下水环境造成影响的有效手段。以广东某石化建设项目为例,在查明水文地质条件的基础上,预测和评价项目运营期对地下水环境可能造成的影响,并针对这种影响提出相应的防渗技术措施且预测了防渗措施的有效性。预测结果表明:采取防渗措施后,污染源强对地下水的影响范围明显缩小,说明防渗措施能有效的防止污染物进入地下水,保护地下水资源。

ANALYSIS ON THE EFFECTIVENESS OF GROUNDWATER PROTECTION MEASURES IN PETROCHEMICAL PROJECTS

Pollutants will infiltrate into groundwater through the aeration zone when pollution accidents occur during the storage and transportation of petrochemical products.This will affect the groundwater quality.Through forecasting,formulating scientific groundwater control measures is effective means to prevent the impacts of the project on the groundwater environment.Taking a petrochemical construction project in Guangdong as an example,this paper predicts and evaluates the possible impacts of the project during operation period on the groundwater environment on the basis of ascertaining the hydrogeological conditions.Then it puts forward corresponding anti-seepage technical measures and predicts the effectiveness of these measures.The prediction results show that the influencing sphere of the pollution source intensity on groundwater is obviously reduced after anti-seepage measures are adopted,which indicates that anti-seepage measures can prevent pollutants from entering the groundwater and protect groundwater resources.
