神府矿区地下水环境背景值初步研究

Elementary Research on Environmental Background Value of Groundwater in Diggings in Shenfu

神府矿区存在煤矿及煤化工生产过程中污染物排放引发的污染问题。结合以往资料,本次研究在神府矿区共采集地下水样品75组,进行了详细的地下水污染调查评价。本文选择数理统计方法,对神府矿区地下水水质指标TDS、TH、Cl-、SO42-、Fe、Mn、NO3-环境背景值进行研究。结果显示:地下水化学元素多以对数正态分布和偏态分布为主,认为地貌单元、水动力条件等因素对研究区浅层地下水指标的空间分布起主要控制作用。

In Shenfu coal mining area and during its chemical producing, it has polluted groundwater heavily. The papers eval-uates the quality of 75 water samples in this region by using mathematical statistics method and measures environmental background value like TDS, TH, Cl-,SO42-,Fe,Mn and NO3-. The result shows that most hydrochemistrical elements are in log-normal distribution and skewed distribution,which indicates that spatial distribution of index for shallow groundwater is mainly effected by geomorphic unit and hydrodynamic condition.
