【摘要】 苏锡常地区浅层地下水资源较为丰富,但水中铁、锰离子含量一直较高。本文在总结现有水质资料的基础上,结合野外现场Eh测试、矿物及土壤的化学成分等成果,对浅层地下水中铁、锰离子的分布规律及其影响因素进行了研究,认为含水介质及土壤的化学成分、地下水系统中的氧化还原环境是造成该区浅层地下水中铁、锰离子含量较高的原因。在此基础上提出:加大开采力度,改善浅层地下水的循环交替速度有利于浅层地下水水质的改良。更多还原

【Abstract】 The Suzhou-Wuxi-Changzhou area is located in the south of the Yangtze River delta.Groundwater resources in the shallow aquifers are abundant.However,the contents of Fe²⁺ and Mn²⁺ in the groundwater is very high.Based on the current data of groundwater quality,the Eh measured in the field and analyses of chemical compositions of soils and minerals,the occurrence of Fe and Mn and influence factors are examined in this paper.The results show that such factors as compositions of the media,environment of oxidation and reduction can influence on the groundwater quality.In order to improve the shallow groundwater quality,a way of improving the groundwater circulation by exploiting the shallow groundwater is put forward.更多还原
