摘　　要：基于三级地下水环境影响评价,以天津市某钢铁加工厂为例,开展了水文地质勘察、地下水水质现状监测与取样分析等工作,采用单因子标准指数法和加附注的综合评价法对潜水含水层地下水质量进行了现状评价。结果表明:项目区地下水为Ⅴ类水,超标项目主要包括钠、氯化物、硫酸根、总硬度、溶解性总固体、总氮、氨氮和化学需氧量。地下水综合评价F值为7. 21~7. 40,质量分级为极差。结合地下水化学特征分析认为,项目区钠、氯化物、硫酸根、总硬度、溶解性总固体超标因素主要与原生地质环境有关,总氮、氨氮超标可能与农田有机化肥施用及原生地质环境有关。On account of the third-level groundwater environmental affect evaluate,exampleathe steel processing plant in tianjin was taken,The present situation of groundwater quality in hydrogeological survey is superviseand extract.The single factor standard index method and the comprehensive assessment method with account are used to assessment the present situation of groundwater quality in the submerged aquifer.Result:The groundwater in the project area is similarⅤwater,and the projects above the standard mainly include total hardness solubility of sodium chloride sulfate,total solid nitrogen,ammonia nitrogen and chemical oxygen demand.The comprehensive assessment F value of groundwater is 7.21~7.40,and the quality classification is poor.Combined with the analysis of groundwater chemical characteristics,The factors of total hardness solubility of sodium chloride sulfate in the project area were mainly related to the primary geological environment.
