中文摘要:
      以地下水污染调查数据为基础,利用城市解剖与水化学分析相结合的方法,对东胜城区及周边地区浅层地下水中硝酸盐分布特征及影响因素进行了分析。结果表明:调查区地下水硝酸盐超标率高达21%,超标点主要分布于人类活动强度较大且水位埋深较浅的地区,局部出现硝酸型地下水;高硝酸盐的地下水具有高矿化度、低pH值、低γCa2+/γCl-、γNa+/γCl-、γHCO3-/γCl-的特征,表明水动力条件越差、变质程度越深且蒸发浓缩越强烈的酸性地下水中越有利于硝酸盐的富集;大气降水对地下水中硝酸盐浓度具有稀释作用,但最终变化态势仍取决于污染源强度。城市化过程中既能产生硝酸盐污染源,又能形成有利于硝酸盐富集的水环境条件,加强对生活污染源的处置与管理是控制城市地区地下水硝酸盐污染的关键所在。
英文摘要:
      Based on the data of groundedwater pollution survey,the paper used the method of combining urban anatomy with hydrogeochemical to analyze the distribution feature and influence factor for nitrate of shallow groundwater in Dongsheng and surrounding area.The result showed that the rate of nitrate exceeding groundwater quality standard is 21% in research area.The excessive points mainly locate in older urban area where the groundwater water level is shallow. The nitrate-type of groundwater appears in some places.The Groundwater with high nitrate has the features of high salinity, low pH and low γCa2+/γCl-, γNa+/γCl- and γHCO3-/γCl-. All these features indicate that acidic groundwater wtih worse hydrodynamic conditions, deeper metamorphic and more intense evaporative concentration is conducive to the enrichment of nitrate.The precipitation has dilutive effect on nitrate concentration, but it still depends on the intensity of pollution. The process of urbanization not only produces nitrate contamination, but also forms the water environment condition which is conducive to the formation of nitrate-rich water. To strengthen the management and disposal of pollutants is the key to control nitrate contamination of groundwater in urban areas.
