| 摘 要： | 通过对成都活水公园人工湿地中的3种优势挺水植物（芦苇、香蒲、伞草）所在塘床进出水口的5个主要水质指标：水中溶解氧（dissolved oxygen, DO）、化学需氧量（chemical oxygen demand, CODcr）、5日生化耗氧量（biochemical oxygen demand in 5 days, BOD5）、总氮（total nitrogen, TN）、总磷（total phosphorus, TP）的全年逐月对比监测，探索不同植物种类对污水净化效率的影响，并对湿地中不同植物塘净化效率产生差异的原因作了较全面的分析讨论。研究表明：这3种水生植物对进入湿地的锦江河水都有明显的净化效果，但它们各自对各污染因子的去除率随季节和植物长势有明显变化。就全年总体而言，3种植物中，芦苇湿地对锦江河水的净化效果较好，其次是香蒲湿地，而伞草湿地对水体中磷的去除效率相对更高。 |

| Abstract： | Some water samples from intakes and outlets of 3 wetland pond beds growing Phragmites communis Trin, Typha angustifolia and Cyperus alternifolius were respectively taken for monitoring and contrasting 5 main water quality indexes including dissolved oxygen (DO), chemical oxygen demand (CODcr), biochemical oxygen demand in 5 days (BOD5), total nitrogen (TN), and total phosphorus (TP) month by month all year around, so as to discover influences of different plant species on water purification efficiency. The paper has briefly discussed the possible reason why the 3 aquatic plant species have respective different wastewater purification efficiencies. It is shown that the three plant species all have evident purification effects to the Jinjiang river flowing to the wetlands, but the removal rates of the pollutants are significantly different according to seasons and the plant growing conditions. In general, the wastewater treatment efficiency of Phragmites communis Trin wetland is the best and Typha angustifolia wetland is the second among the 3 plant species, whereas, Cyperus alternifolius is better to remove overmuch phosphorus than the other 2 aquatic plant species. |
