摘要
研究浅层地下水的质量分布特征与污染评价对地下水资源的科学管理与保护具有重要意义。本文以山西阳泉经济技术开发区南区为例,采用单指标评价方法与综合评价方法对地下水化学组成进行分析,利用GIS技术进行质量分布分析,运用污染指数法对地下水污染进行评价,对11口新建井的91个地下水污染指标进行分析。单指标评价法与综合指标评价法的研究结果显示,YQ03和YQ11监测井为Ⅲ类水;样品YQ01和YQ09监测井为Ⅳ类水;样品YQ02、YQ04、YQ05、YQ06和YQ10监测井为Ⅴ类水。污染指数法对地下水污染的评价结果表明,YQ02、YQ04、YQ05、YQ06、YQ09和YQ10点位发生的污染主要为总硬度、溶解性总固体、硫酸盐、氯化物、铁、锰、铝、耗氧量、钠、氟化物、钡等11个指标。
It is of great significance to study the quality distribution characteristics and pollution assessment of shallow groundwater for the scientific management and protection of groundwater resources.Taking the southern area of Yangquan Economic and Technological Development Zone in Shanxi Province as an example,this paper analyzes the chemical composition of groundwater by single index evaluation method and comprehensive evaluation method,analyzes the quality distribution of groundwater by GIS technology,evaluates the groundwater pollution by pollution index method,and analyzes 91 groundwater pollution indicators from 11 new Wells.The results of single index evaluation method and comprehensive index evaluation method show that YQ03 and YQ11 monitoring Wells are Class III water;Sample YQ01 and YQ09 monitoring Wells are Class IV water;Sample YQ02,YQ04,YQ05,YQ06 and YQ10 monitoring Wells are Class V water.The evaluation results of groundwater pollution by pollution index method show that the pollution at YQ02,YQ04,YQ05,YQ06,YQ09 and YQ10 points mainly consists of 11 indexes,such as total hardness,total dissolved solids,sulfate,chloride,iron,manganese,aluminum,oxygen consumption,sodium,fluoride and barium.
