| 摘 要： | 人工湿地污水系统由于其高效、易管理和低运行费用等特点而被用于生活和工业污水处理。湿地植物在人工湿地中起着重要的作用,不但可以直接摄取和利用污水中的营养物质、富集污水中的重金属等有毒有害物质,而且还能输送氧气到根区,提供根区微生物生长、繁殖和降解过程对氧的需求。阐述了植物在湿地系统中的重要作用,分析了湿地植物在人工湿地处理污水起作用的影响因素。

| Abstract: | Constructed wetland was often used in treating domestic and industrial wastewater for its advantages such as high efficient,easy management and low cost.Macrophytes played an important role in wetland,including assimilating and storing nutrient elements in wastewater,enriching harmful substances,transporting oxygen to the root zone and providing oxygen to the growth,reproduction and degradation of microorganism.The important function of macrophytes in wetland system were discussed.The influencing factors of macrophysics on wastewater purifying were analyzed. |
