摘要
人工湿地具有去污效果好、运行费用低、易于维护、可缓冲水力和污染负荷的冲击等优点,在环境污染与治理方面备受青睐。为促进人工湿地在环境污染治理中的广泛应用,对人工湿地的类型及其主要要素的用途与相互关系详细阐述,并对人工湿地的污染物去除机理进行分析。研究表明,人工湿地净化所涉及的污染物去除影响因素较多,作用机理较为复杂,许多问题需进一步研究。
Constructed wetland has attracted a great deal of attention from researchers and governments due to its unique advantages,including high removal efficiency,low cost and easy to manage,in the remediation of environment pollution.To promote application of constructed wetland in restoration of environmental pollution,types and main components of constructed wetland and their work theory and correlations between these components were reviewed and discussed in the present review.In addition,the removal mechanisms of main kinds of constructed wetland were reviewed as well.However,there are numbers of factors that influence the pollutants removal efficiency of constructed wetland and their working mechanisms are complex,more studies addressed on these issues should be conducted.
