摘要
由于目前缺乏一套完整成熟的地下水污染风险源准确识别与分级方法,在综合解析污染源结构、污染物输移过程评价的基础上,构建了涵盖地下水易污性和地下水污染源两部分多因素耦合的风险源识别模型,其中从污染源特性和污染物性质两方面建立了污染源危害性评价参数体系.以地下水易污性指数和污染源潜在危害性评价指数作为风险源分级指标,采用乘积模型进行了风险源的评价与分级.选择某水源地对所建方法进行实例分析,确定了地下水污染的高风险源区.结果表明,污染源和地下水易污性共同决定了地下水污染的风险源,所建方法对地下水污染的预防及污染源的有效监管有重要意义.
There is not a well-developed method to identify accurately the risk source of groundwater pollution at present,so a risk source identification model including the vulnerability and contaminant source,coupling of many factors,was constructed based on the comprehensive analysis of contaminant source structure and the evaluation of contaminant transport process in this study.Hazard assessment parameters system of contaminant source was established from the characteristics of sources and pollutants.Groundwater vulnerability index and potential hazard assessment index of contaminant source were used to evaluate and classify the risk source by product model.The method was applied to a groundwater supply source,and which identified high-risk areas of groundwater contamination.The results show that risk source of groundwater pollution was effectively determined by contaminant source and the vulnerability assessment,and the method was of great importance for the prevention of groundwater contamination and effective supervision of contaminant source.
