广西龙布排泥库地下水多元示踪试验研究

以具有复杂水文地质背景的广西平果铝业公司龙布排泥库为研究区．采用钼酸铵、萤光素钠和氯化锌三种试剂．综合考虑各种水文地质条件和其它影响因素．在测区48km^2范围内，布置投放点3个．接收点19个,进行地下水多元示踪试验，为该尾矿库的设计与建设提供必要的水文地质依据，分析库内与库外的地下水水力联系情况，尤其库内与布见水库的水力联系情况，并计算地下水流速，确定地下水流向的主导方向，对于评价该尾矿库对布见水库水源的污染情况具有重要意义。

Multi-element Trace Testing Study of Ground Water in Painiku,Longbu,Guangxi

The complex hydrogeological background of the study area (Painiku, Longbu, Guangxi) and other impact factors were considered in this paper. In the measured area (48 km 2), three trace reagents (molybdenum acid ammonium, fluorescein natrium, zinc chloride) were used in multi-element trace testing of ground water (3 putting points, 19 incepting points). According to this testing, the hydrogeologic conditions became clear; the hydraulic relation between the inside and the outside of Painiku was analyzed, especially between the inside of Painiku and Pujian Reservoir; the groundwater velocity was calculated; and the main directions of groundwater flow were confirmed. This study has important significance for the assessment of contamination of this trail storage to waterhead in Pujian Reservoir.
