摘要
通过调查磷石膏渣闭库后近5a对地下水中硫酸根离子的监测情况,综合分析了磷石膏渣场闭库措施的合理性。调查结果表明,磷石膏渣场中硫酸根离子在采取闭库措施后其产量明显下降,说明闭库措施尤其是HDPE膜起到了明显的降低渗滤液产量的作用。
Through monitoring sulfate ion in groundwater in the past five years of a closed phosphorous gypsum slag yard, the feasibility of the closing measures of the phosphorus gypsum slag yard was analyzed. The results showed that the yield of the sulfate ion in the field of the phosphorus gypsum residue decreased significantly after closing the yard, which indicated that the measures, especially the HDPE film, played a significant role in reducing the yield of leachate.
