本文以大冶湖底泥为研究对象，拟通过对大冶湖底泥的理化特性及重金属元素的分析，探讨将底泥应用于矿山复垦的可行性，以实现变废为宝，改善生态环境效应。研究结果表明，以《农用污泥污染物控制标准》为基准，大冶湖底泥PH值和含水率满足复垦要求，但有机质偏低，需额外添加营养物质以促进生物生长。底泥中Zn元素总含量及其存在形态，以及风险评价编码(RAC)和次生相与原生相分布比值(RSP)都表明Zn元素不会造成环境危害，但Pb、Cd和Cu元素需进行稳定化处理。
Bottom sediment of Daye Lake was selected as the study object of this investigation. The physical and chemical characteristics, and heavy metal elements of the sediment were analyzed to discuss the possibility of using the sediment as the soil for mine reclamation. The results indicated that the PH value and water content of the sediment were met the standard for reclamation. However, the organic matter was lower than the standard and needed an addition for the growth of the plants. The results of total content and the speciation analysis of Zn element in the sediment, as well as the value of Risk Assessment Code (RAC) and Ratio of Secondary Phase and Primary Phase (RSP) for Zn, implied that Zn would not cause environmental damage. However, the stabilization treatment of Pb, Cu, and Cd was necessary.
