河北某电镀污染场地Cr~(6+)污染调查
|
摘要
为查明河北某电镀污染场地Cr~(6+)的污染程度和空间分布,并对其可能影响的污染范围及风险进行预测,采用取样化验、三维数值模拟等方法对污染场地进行调查和评价。结果表明:污染场地在未进行人工干预治理时,污染物受到地下水流向和含水层介质的影响,在电镀废水停止泄露后的180 d内,调查区西南部大片区域的地下水有被污染的风险。
In order to ascertain the pollution degree and spatial distribution of Cr~(6+)in an electroplating contaminated site in Hebei Province and predict its possible contamination scope and risk,sampling test and three-dimensional numerical simulation were used to investigate and evaluate the contaminated site. The evaluation results show that the pollutants are affected by groundwater flow direction and aquifer medium when the contaminated site is not treated by manual intervention.Within 180 days after the electroplating wastewater stops leaking,the groundwater in a large area of southwest of the investigation area will be polluted.
