摘要: 为了研究某金矿带河流不同相态中Hg分布关系及时空变异性，笔者通过野外调研、数据测试分析等手段，对双桥河中的Hg进行时空剖析得出：①对比研究矿区双桥河开矿前、开矿鼎盛期、治理期河流河水、底泥及治理期悬浮物数据对比，表明河流水质和底泥在开矿鼎盛期Hg含量最高，到2015、2016年治理期已经出现改观，从治理期3种介质中Hg对比可知，系统监测河水-悬浮物-底泥中Hg含量能更准确评价河流的污染现状和未来发展方向。②通过对比双桥河河水、悬浮物、底泥中Hg含量沿程变化，得到在山区Hg浓度关系为底泥 > 河水；而在山外细颗粒物质增大和水力坡度减缓的平原区，Hg在3种介质中均有存在，浓度关系为底泥 > 悬浮物 > 河水，总体上，河流中Hg主要赋存在底泥、悬浮物中，水溶态基本没有。研究结果将为金矿区Hg污染的水环境管理与防治及修复受损生态系统提供可参考性依据。Abstract: In order to studying mercury conversion relation and the time empty variation in water,suspend thing and bottom silt of the river in a gold mine, the mercury time-space contest in Shuangqiao river has been analyzed by using investigation and testing data. ①The monitoring data about the river water, sediment and suspended solids of shuangqiao river before mining, mining height and mining management phase have been studyed comparatively, the result governances that river water and sediment mercury content is the highest in the mining height phase,the situation has been changed in 2015, 2016.The contrasting resuit of mercury content in three phases show that, the systematic monitoring inriver water, suspended thing and bottom silt can be used to evaluation present situation and future development direction of river pollution more accurately; ②After contrasting the mercury contents of river wate,suspend thing and bottom silt changed along the Shuangqiao river, The mercury concentration is bottom silt > river water in the mountain, while the mercury concentration is suspend thing > bottom silt > river water, in the plain area with thin grain material aggrandizement and slowly water power slope, the mercury occurred as the solid form of bottom silt and suspended thing,without any water soluble states. This research result will provide some reference basis for the water environment management of mercury pollution in the gold mine area, as well as the prevention, cure and repair of damaged eco-system.
