  • 摘要: 复合型人工湿地越来越多地被应用在面源污染管理中。不同类型的人工湿地对氮素的去除机理和去除性能是不同的。氮素在湿地生态系统中的去除受多种因素的影响和制约,不同的研究中氮素的去除效率变化较大。通过对韩国西部一复合型人工湿地中氮素的去除能力研究,分析了氮素的去除效率以及水力负荷对去除性能的影响,进而分析了人工湿地去除氮素的主要机理。结果表明,氨氮(NH4+-N)、硝酸盐氮(NO3--N)、凯式氮(TKN)和总氮(TN)的平均去除效率分别为13%、29%、35.3和26%。其中有机氮的去除是该复合型人工湿地中氮素去除的主要原因。水力负荷和先行干期天数对氮素的去除能力有一定影响。较长的先行干期天数和较低水力负荷可以提高氮素的去除效率。
    Abstract: Integrated constructed wetlands have been applied in the management of no-point source pollution. The pollutants removal mechanisms are different in different types of constructed wetlands. And the wetlands performance is variable under different operation conditions; it can be affected by many factors. A pilot-scale wetland was constructed for the control of nonpoint source pollution (NPS) in Korea. Its performance on the nitrogen removal was analyzed. Results indicated that the efficiencies of ammonia (NH4-N), nitrate (NO3-N), total Kjeldahl nitrogen (TKN) and total nitrogen (TN) were 13%, 29%, 35.3% and 26%, respectively. Furthermore, the removal of organic-nitrogen was the main factor affecting the nitrogen removal in this wetland. The effects of hydraulics loading rate and antecedent dry days on the nitrogen removal were determined. The lower hydraulic loading rate and the longer antecedent dry days can result in a higher nitrogen removal.
