中文摘要:
      潮汐流人工湿地作为一种间歇式进水的新型人工湿地生态系统,可以显著提高人工湿地的氧环境,弥补植物根系放氧的不足,有利于N的去除.近几年来,利用潮汐流人工湿地去除水体中的N等污染物以改善水质并促进水资源再利用已经得到了广泛关注.潮汐流人工湿地通过物理、化学、生物等各种途径去除N等污染物依赖于各种环境要素.文中介绍了近年来有关潮汐流人工湿地N去除研究成果,综述不同类型潮汐流人工湿地N去除效果,分析潮汐流人工湿地N去除的影响因素,并提出今后应从微观角度、空间角度、工艺设计角度以及模型模拟角度4个方面加强研究,从而为潮汐流人工湿地设计奠定理论基础.
英文摘要:
      As a new type of constructed wetland ecosystem characterized by intermittent influx, tidal-flow constructed wetland is able to tangibly increase the oxygen concentration of constructed wetland, make up the lack in oxygen released from plant roots and enhance nitrogen removal efficiency. In recent years, the use of tidal-flow constructed wetland to remove the nitrogen pollutants and improve water quality for reuse has aroused wide concerns. Nitrogen removal efficiency of tidal-flow constructed wetland could be enhanced through many approaches, i.e., physical, chemical, and biological approaches, which also depends on various environmental factors. This paper reviewed the research progress on nitrogen removal efficiency of tidal-flow constructed wetland, introduced the effect of nitrogen removal of different types of tidal-flow constructed wetland, analyzed the factors influencing their nitrogen removal, and put forward the key perspectives for future study, including microcosmic, spatial, process design and simulation model perspectives. This study is supposed to lay a theoretical foundation for tidal-flow constructed wetland design.
