【摘要】 针对地下水有机污染的特征,采用检出限和EPA水质标准的二级标准标准化单污染因子,建立了适用于地下水有机污染评价的分级综合指数模型,该模型层次清楚,物理意义明确,避免了一级评价标准产生的极差问题,实例分析表明对地下水质有机污染评价有较好的适用性。更多还原

【Abstract】 In accordance with the characteristics of the organic pollution on the groundwater,a graded comprehensive index model,with clarified levels and explicit physical significance,is established herein based on both the limit of detection and the single contaminated factor standardized in the secondary standard given in the relevant EPA water quality standard;with which the problems from the range produced from the primary evaluation standard concerned are avoided.The case study demonstrates that better applicability to evaluate the organic pollution on the quality of the groundwater can be obtained from the model.更多还原
