| 摘 要： | 砷在环境中普遍存在，因其高毒性，世界卫生组织将砷污染列为重大公共卫生问题。因此，科学家们在不断寻求科学有效的砷污染去除方法。人工湿地砷污染去除系统自上世纪七十年代推出以来，因其环境友好、成本低廉的特性得到蓬勃发展，快速成为绿色环保修复技术之一。人工湿地被认为是理想的砷富集去除场所，其对砷污染的去除方式主要通过植物和微生物相互作用及腐殖酸强化修复来实现。本文通过砷污染治理历史及技术发展、人工湿地的兴起及砷在湿地生态系统中的赋存状态以及人工湿地生态系统砷污染去除三个方面综述了人工湿地砷污染去除的研究进展。通过大量文献综述分析，我们认为在人工湿地砷污染去除的后续研究工作中，应着重研究砷在湿地生态系统中的扩散迁移及演变规律，构建湿地生态系统沉水-浮水-挺水植物立体结构，并不断探索植物-微生物及腐殖酸强化修复对砷污染的协同阻滞及界面作用。

| Abstract: | Arsenic (As) is a ubiquitous element in the environment, high toxicity of As make them considered as a major public health issue by the World Health Organization (WHO). Therefore, scientists are constantly searching for scientific and effective methods to remove arsenic pollution. Since 1970s, constructed wetland arsenic removal system has been developing rapidly because of its environment friendly and low cost. Constructed wetlands has rapidly become one of the green environmental protection remediation technology. Constructed wetland is an ideal place for arsenic enrichment and removal. Removing arsenic pollution is mainly achieved through the interaction of humus, plants and microorganisms. In this paper, the research progress of arsenic pollution removal in constructed wetland was summarized from three aspects: 1) the history and technology development of arsenic pollution remove, 2) the development history of constructed wetland and the occurrence of arsenic in wetland ecosystem and 3) arsenic pollution removal technology and its application in the constructed wetland ecosystem. According to the contents mentioned above, we suggest to pay more attention to diffusion, migration and evolution of arsenic in wetland ecosystem. We also should focus on the construction of submerged-floating-emergent plant system in wetland, and research on the synergistic and interface effect of plant microorganism and humic acid enhanced remediation on arsenic pollution. |
