摘要
由于受到磷石膏库岩溶渗漏影响 ,大干沟岩溶地下水磷污染问题严重 ,并且威胁着乌江渡水库水资源环境。通过岩溶渗漏条件分析及污染评价得出 :①污染渗漏形式可分为岩溶管道和裂隙类型 ;②污染途径可分为直接和间接污染 ;③磷污染不仅使岩溶地下水不能作为饮用水、生活用水和灌溉用水 ,而且严重污染了地面水 ,并使水库产生富营养化问题。
The Dagangou karst groundwater has been seriously polluted as a result of karst leakage of phosphate gypsum site,threatening the water resource environment of Wujiangdu reservoir.After analysis of the leakage condition and evaluation of the pollution we come to the conclusion:(1)The pollution leakage occurs in karst conduit and fissure;(2)The pollution goes through direct and indirect channels;(3)The phosphoric polluted groundwater is undrinkable and cannot be used for wash or irrigation.It also contaminates the surface water and makes the reservoir enriched.
