| 摘 要： | 研究了用于处理凡口铅锌矿选矿废水的宽叶香蒲(Typha latifolia)人工湿地系统沉积物中重金属Pb、Zn、Cu和Cd的分布。沉积物略呈碱性,在各层沉积物中,DTPA-Zn质量分数高于DTPA-Pb质量分数。冬季(11~12月)湿地系统中3个处理池进水口的沉积物结合水中的Pb、Zn、Cu和Cd质量分数与春季(1~3月)的相比较,有显著的差异。湿地处理系统中Pb、Zn、Cu和Cd主要沉积在表层土壤中;但3个处理池入水口和出水口不同深度的沉积物pH值没有显著差异(p<0.05),表明pH值与重金属含量并不存在相关性。 |

| Abstract: | Distributions of Pb, Zn, Cu, and Cd in sediment at Fankou Pb/Zn wetland dominated by Typha latifolia have been studied. The concentration of DTPA-Zn was higher than DTPA-Pb in sediment. The concentrations of Pb, Zn, Cu, and Cd in pore water in spring were significantly higher than in winter. From cell 2 to cell 4, concentrations of Pb, Zn, Cu, and Cd in the top 10 cm of sediment were higher than in the 10-20 cm or 20-30 cm sediment. However, sediment pH in different layers was not significantly different (p>0.05), which indicate that the concentrations of metals and pH values in sediment did not have a obvious correlation. |
