摘要

摘要: 以商丘市为研究对象,分析了 8 种重金属(Cr、Ni、Cu、Zn、As、Pb、Cd、Hg)的污染特征,采用富集因子法和浸出毒性试验确定商丘市再生产品及其原材料的重金属污染程度,并进行潜在生态风险评价。结果表明:再生产品原材料中,重金属Hg是主要污染因子,其次是Cr和Ni,均对重金属浸出率和潜在生态风险具有较大贡献,可能原因是受到了人为活动的影响,应对其进行避雨存放;再生产品中,重金属Hg是主要污染因子,其次是Ni。再生产品的生态风险水平低于再生产品原材料,说明该资源化利用途径有利于降低建筑垃圾中重金属的潜在生态风险。因此,再生产品作为建筑垃圾的资源化产物,具有良好的应用前景。

Abstract: Taking Shangqiu in Henan province as the research object, the pollution characteristics of eight heavy metals Cr, Ni, Cu, Zn, As, Pb, Cd and Hg were analyzed. The degree of pollution caused by heavy metals in the recycled products and their raw materials in Shangqiu was determined through the enrichment factor method and toxicity-leaching test, and the potential ecological risk was also evaluated. The results showed that, in raw material of the recycled products, Hg was the main pollution factor, followed by Cr and Ni, and all of them contributed greatly to the leaching rate of heavy metals and the potential ecological risk index. They might be affected by human activities and should be stored in shelter from the rain. In the recycled products, Hg was the main pollution factor, followed by Ni. The ecological risk of the recycled products was lower than that of the raw materials of the recycled products, indicating that this recycling approach was conducive to reduce the potential ecological risk of heavy metals in construction waste. Therefore, the recycled products have a good application prospect.
