中文摘要 | 本研究主要分析臺北縣大漢溪高灘地新海二期人工濕地各淨化單元水中可溶離子,以評估人工濕地對於陰陽離子之移除效益。由入水口與放流的水質比較結果顯示,新海人工濕地對於污水的電導度、NH4+、K+、PO43-及無機態氮(NH4+-N, NO3--N-及NO2--N)具有顯著的削減作用,而對於SO42-、Ca2+及Mg2+之移除效果並不顯著;在人工濕地放流水之溶氧、pH 值及NO3-及NO2-則呈顯著的增加。隨著污水流經各淨水單元其無機態氮削減效能具顯著差異,其中以第2 密植區最高,分析其相關環境因子顯示各淨水單元中的挺水植物面積與溶氧呈負相關,但與NH4+呈正相關,顯示人工濕地中植物的比例會影響到其無機氮的移除效能。 |
英文摘要 | The study was conducted in the second Hsin-Hai constructed wetland of Da-Han river in Taipei County. We measured the soluble nutrients in different units to evaluate the effectiveness of nutrient removal. Compared with soluble nutrients of waste water between inflow and outflow of Hsin-Hai constructed wetland, the conductivity, NH4 +, K+,PO4 3-and inorganic-nitrogen(DIN=NH4 +-N+NO3--N+NO2--N) were decrease in outflowwaste water and significant difference, while SO4 2-, Ca2+, and Mg2+ were insignificant. On the contrary, DO, pH, NO3- and NO2- were increased in the outflow. The removal efficiency of DIN was improved, while the waste water flow through the different ponds.The second dense macrophyte pond has the highest DIN removal efficiency. There was a negative correlation between DO and emergent macrophytes area and this area was positive relation with NH4 +. Our results also showed the nitrogen removal efficiency of constructed wetlands are influenced by macrophytes area. |
