【摘要】 以焦作市演马矿煤矸石山为对象,采集该处新鲜和风化煤矸石以及附近地下水样品,检测其中Cl-、SO42-、苯并(a)芘、Mn等22种污染物的含量,并采用超标倍数法和实测浓度法对地下水受污染状况进行分析研究。地下水中污染物含量与煤矸石山距离呈负相关,且在丰水期和枯水期存在一定差异。更多还原

【Abstract】 To study the pollution caused by coal waste rock dump,unweathered and weathered coal waste rocks were collected from Yanma coal waste rock dump,and groundwater was gathered near the dump.22 contaminations,such as Cl-,SO2-4,Mn,and so on,were examined,and exceeding standard multiple and practice concentration were used to assess the regime of underground water pollution.The results are as follows: The contamination contents were negative correlation with the distance of the coal waste rock dump,and the contents were different between high water seasons and low water seasons.更多还原
