Abstract:
The hydraulic characteristics of vertical flow constructed wetlands was investigated, and the influence of these characteristics on wastewater purifying efficiency was studied as an emphasis. The results of the experiments in small scale plots and medium scale plots showed the plant roots, with the physical and biological effects, play a significant role in hydraulics and the wastewater purifying efficiency. The other characteristics such as retention time, effluent velocity and influent load also directly affect the wastewater purifying efficiency of constructed wetland. To get a better understanding of the hydraulics will be crucial to the improvement of purifying efficiency and facilitate the practical use of constructed wetland.
