潮汐流-水平潜流组合人工湿地的污水处理效果
Purification capacities of hybrid tidal flow and horizontal subsurface flow constructed wetlands systems
摘要
Abstract
For the investigation of purification capacity of hybrid constructed wetlands, the tidal flow-horizontal flow （TF- HF） system and horizontal flow-tidal flow （HF-TF） system were constructed on laboratorial scale. At the flood drain ratio of 12 h ： 12 h in tidal wetlands, hydraulic retention time of 4 d in horizontal flow wetlands, and recirculation of 1 ： 1 ,the average total organic carbon （TOC） removal rates of the two systems were 90.2% and 91.3%, but the average removal rates of NH4＋ -N were 19.5% and 39.2%, respectively. The average removal rates of total nitrogen （TN） were 10.3% for TF-HF and 30.5% for HF-TF. Results indicated that the purification capacity of HF-TF system was much higher than that of the TF-HF system. The findings of this work may provide a theoretical basis for the application of combined tidal flow and horizontal subsurface flow constructed wetlands in practice.关键词
