摘要
通过综述传统人工湿地的主要填料,结合其物理、化学性质直接对人工湿地污水处理系统的植物生长和污水净化效果等影响因素,阐明了传统基质的人工湿地已逐渐被矿物填料基质所替代。分析表明人工湿地系统仅靠单一填料,往往无法达到污染物去除要求,应利用组合填料间的协同作用方可达到更好的污染物去除效果。同时本次提出人工湿地矿物填料的研究及应用现状、新型材料的快速发展与应用,以期为人工湿地矿物填料的选择过程提供参考。
In recent years, the application of mineral fillers is a great innovation in the field of constructed wetlands. In this paper, the main fillers of traditional constructed wetlands are summarized, along with the physical, chemical properties of the traditional constructed wetlands directly affect the plant growth and sewage purification effect of the constructed wetlands sewage treatment system. It is clarified that the traditional constructed wetlands have gradually been replaced by mineral fillers. The analysis shows that the constructed wetland system cannot meet the requirement of pollutant removal only by single filler, and better pollutant removal effect can be achieved by using the synergistic effect of the combined fillers. At the same time, the research and application status of mineral fillers in constructed wetlands, the rapid development and application of new materials are put forward in order to provide reference for the selection process of mineral fillers in constructed wetlands.
