- 摘要:
- 为研究污泥处理湿地中芦苇对重金属的积累和分布特征，分析了污泥处理湿地（STW1、STW2、STW3）中芦苇和积存污泥的Cr、Ni、Cu、Zn、As、Pb含量情况。结果表明，芦苇对Ni、Zn的富集能力较强，对Pb、Cu的富集能力较弱。Ni、As、Pb、Zn从芦苇根部向地上部分转移的能力较强，而Cr、Cu的转移能力较弱；As、Pb易向芦苇叶组织中转移，而Ni、Zn更易向茎组织中转移。芦苇中Cr、Cu、Pb、As的占比为根组织>叶组织>茎组织，其中STW3的根组织与叶组织中As占比相当；芦苇中Ni、Zn的占比为根组织>茎组织>叶组织。STW3芦苇中Cr的平均含量比STW2低41%，且Cu、Pb平均含量均略低于STW2，只有Zn、Ni的平均含量略高于STW2。通风管的存在提高了植物对重金属的吸收能力，因此配置通风管的STW2更具有去除污泥中重金属的潜力。
- Abstract:
- In order to study the accumulation and distribution characteristics of heavy metals in reeds from sludge treatment wetlands, experiments were carried out to analyze Cr, Ni, Cu, Zn, As and Pb contents in the reeds and accumulated sludge in three sludge treatment wetlands (STW1, STW2 and STW3). The results showed that the reeds from sludge treatment wetlands had a stronger enrichment capacity for Ni and Zn, and a weaker enrichment capacity for Pb and Cu. Ni, As, Pb and Zn had a stronger ability to be transferred from the roots to the aboveground part of the reeds, and Cr and Cu had a weaker ability to be transferred. As and Pb could be easily transferred to the leaf tissues of the reeds, while Ni and Zn could be transferred to the stem tissues more easily. In reeds, the proportions of Cr, Cu, Pb and As followed the order: root tissue>leaf tissue>stem tissue. Among these, the proportion of As in the root tissue of STW3 was comparable to that in the leaf tissue. For Ni and Zn in reeds, the proportions followed the order: root tissue>stem tissue>leaf tissue. The average content of Cr in reeds in STW3 was 41% lower than that in STW2, and the average contents of Cu and Pb were all slightly lower than STW2, and only the average contents of Zn and Ni was slightly higher than that of STW2. The presence of the vent pipes increased the uptake capacity of heavy metals by the plant, and thus STW2 configured with vent pipes had more potential for removing heavy metals from the sludge.
