基于跌置指数法的危险废物填埋场地下水污染风险评价
|
摘要
以江苏省某危险废物填埋场为研究案例,利用迭置指数法的风险评价方法综合考虑了以填埋场自身潜在风险、含水层脆弱性、风险受体暴露性为主的3个方面的影响因素,构建了包含16个评价指标的指标体系,分析了各评价指标的权重,并建立了综合指数风险评价模型。经计算,该危险废物填埋场地下水风险综合指标为4.682,参考危险废物填埋场地下水污染风险分级标准,得出该危险废物填埋场地下水污染风险等级为较低。将填埋场自身潜在性质、含水层脆弱性以及风险受体暴露性三方面综合考虑的地下水污染风险评价方法,不仅可为污染场地的防治提供科学依据,可以为场址的选择参考。
Taking a hazardous waste landfill in Jiangsu Province as a case study, the use of risk-based assessment method superposed exponential law considers the potential risks to the landfill itself, aquifer vulnerability, risk exposure of the main receptor 3 factors aspect, constructs an index system containing 16 index, and analyzes the weight of each evaluation index weight, and the establishment of a comprehensive risk assessment index model. Calculated that the risk of groundwater hazardous waste landfill comprehensive index of 4.6823, with reference to hazardous waste landfill site under the Water Pollution risk classification criteria, obtained the hazardous waste landfill Water pollution risk level is low at the venue. Groundwater contamination risk assessment method to the nature of the potential landfill itself, aquifer vulnerability and risk exposure of the receptor in three areas considered, not only can provide a scientific basis, you can select the site as a reference for the prevention and treatment of contaminated sites.
