地下水源地污染源危害性评价方法研究

基于GIS技术平台、层次分析方法,构建了涵盖污染源特性与污染物属性两大方面的8项指标的污染源危害性评价的参数体系,建立了污染源特性指标评价与污染物属性指标评价的耦合模型,解决了地下水源地污染源的量化评价问题.应用所建方法评价了某地下水源地污染源对地下水的危害性.结果表明, 研究区的排污沟、石化公司周边的渗坑群及南部和东部某河滩的渗坑对地下水的潜在危害程度最高,石化公司的潜在危害性中等,其余区域危害性较低.这为污染源的有效监管提供技术支撑.

Study on the hazard assessment method of pollution sources in groundwater source fields

Based on GIS technology platform and analytic hierarchy process,the hazard assessment parameters system for groundwater pollution sources,which was involved in eight indexes related to characteristics of pollution sources and properties of pollutants,were constructed.The coupling model was established by the assessment of source characteristics and pollutant properties.The problem of quantitative evaluation of pollution sources in a groundwater source field was solved.This established method was applied to assess the hazard of pollution sources in some groundwater source field.The potential groundwater hazard degree of the drainage ditches,the seepage pits around the petrochemical corporation and in the river shoal zone in the southern and eastern of study area was high;the corresponding degrees of the petrochemical corporation and the rest areas were medial and low.The results of hazard assessment will provide technical support for effective supervision of pollution sources.
