中文摘要：人工湿地具有去除污染效果好、运行费用低和易维护等特点,已被广泛用于污水处理中。湿地植物在其中起着重要作用,主要包括直接吸收氮、磷等污染物,通过根系输氧促进根区的氧化还原反应与好氧微生物活动及增强和维持介质的水力传输等。综述了人工湿地植物的去污机理,阐述了湿地植物对生物可降解的有机物、营养性污染物和有毒有害物质净化的研究成果与应用,并展望今后进一步研究的重点。

外文摘要：Constructed wetland is often employed for treating various wastewaters because of its many advantages： low overall cost, high effieieneies for pollutant removal, simple operation and stable performance. Macrophytes in such constructed wetlands perform many ecological functions, including assimilating and storing nutrient elements such as nitrogen and phosphorus, transporting O2 to the root zone, providing substrates for microbes, enhancing and maintaining hydraulic conductivity. These functions are responsible for the enhanced removal of organic matter, nutrient and toxic substance in the wetland populated with desirable macrophytes. Establishing the most effective plant community, physiology of macrophytes, effects of macrophytes on oxygen production and transport, and interactions between the plants and microorganisms in the wetland were identified as the areas that need additional research.
