摘　　要：为了解决粉质黏土修复困难的问题,开展了粉质黏土重金属铅的造粒堆浸中试试验研究。结果显示:造粒堆浸的助渗效果显著,且污染物去除成效明显。根据试验结果设计造粒堆浸的工艺,并应用于石油烃(C10-C40)粉质黏土污染修复工程,修复后的污染物低于目标值,为粉质黏土造粒堆浸的工业应用提供参考。In order to solve the problem of difficult remediation of silty clay, the pilot test of granulation heap leaching of heavy metal lead in silty clay was carried out. The results showed that the seepage aid effect of granulation heap leaching was remarkable, and the effect of pollutant removal was obvious. According to the test results, the granulation pile leaching process was designed and applied to the petroleum hydrocarbon(C10-C40) silty clay pollution remediation project, and the remediated pollutants were lower than the target value, which provided a reference for the industrial application of silty clay granulation heap leaching.
