  • 摘要: 为了揭示潜流人工湿地对污染河水的净化机制，通过构建实验室规模和中试规模2种尺度的人工湿地，系统分析了人工湿地净化污染河水过程中的基质特性、微生物特性和植物作用。结果表明，2种尺度人工湿地对悬浮固体（SS 95.86%，94.74%）和有机物（COD 85.29%，80.41%；BOD5 90.60%，89.99%）的去除效果相近，而实验室规模湿地对营养物的去除效果（TN 30.13%，TP 76.89%）优于中试规模湿地（TN 20.27%，TP 52.45%）。实验室规模人工湿地的微生物群落多样性和微生物数量更高，并且具有能够脱氮和降解有机物的特属优势菌种黄杆菌和金黄杆菌。中试规模人工湿地能够更好地为植物生长提供适宜的环境条件，中试规模湿地中的植物生物量（1.47 kg·m-2）高于实验室规模湿地（1.12 kg·m-2），而且植物在湿地氮磷去除中的贡献率（TN 23.55%，TP 8.80%）也高于实验室规模湿地（TN 11.03%，TP 4.46%）。
    Abstract: In order to investigate the mechanism of subsurface constructed wetland (SSF CW) for polluted river water purification, a lab scale and a pilot scale SSF CW were constructed to analyze the roles of substrates, microorganism and plants in CW. The results indicated that the two different scales CWs showed similar removal efficiencies for suspended solids (SS 95.86%, 94.74%) and organic matter (COD 85.29%, 80.41%; BOD5 90.60%, 89.99%). However, the lab scale wetland showed higher nutrient removal rates (TN 30.13%, TP 76.89%) than the pilot scale wetland (TN 20.27%, TP 52.45%). Furthermore, the diversity and the number of microbial communities in the lab scale wetland were both higher than those in the pilot scale. The Flavobacterium and Chryseobacterium were only found in the lab scale wetland which could degrade nitrogen and organic matter simultaneously. Finally, the pilot scale CW provided more favorable environment for plants growth than the lab scale. The plants played an important function especially in pilot scale CW for nitrogen and phosphorus removal (TN 23.55%, TP 8.80%), with TN 11.03%, TP 4.46% in lab scale CW.
