本研究評估新北市鹿角溪及打鳥埤人工溼地污染物削減功能，人工溼地包含5個處理單元，水質與流量為2013至2014年之監測資料，研究目的為(1)評估人工溼地污染物削減率、(2)探討污染物入流負荷與去除速率之關係、(3)評估人工溼地處理單元去除污染物。水質項目包含生化需氧量(BOD)、氨氮(NH3-N)、總氮(TN)、總磷(TP)、總大腸桿菌群(TC)，此外，以盒鬚圖法(Box and whisker plot)與出流機率法(effluent probability method, EPM)計算污染物削減率。結果顯示鹿角溪人工溼地之水力停留時間與水力負荷分別為19天及0.02 m/day，打鳥埤人工溼地則分別為14天及0.05 m/day。EPM計算BOD、NH3-N、TN、TP與TC之去除率分別為47.5%、99.9%、85.1%、85.6%與97.5%，以盒鬚圖中位數計算去除率之結果與EPM結果亦相近。人工溼地污染物去除速率與污染物入流負荷量呈良好線性關係，BOD、TN、TP、NH3-N及TC之決定係數(R2)為0.87-0.99，其相關性可作為人工溼地設計參數。此外，鹿角溪與打鳥埤人工溼地於第3處理單元，BOD與營養源(TP、TN) 藉水生植栽去除率分別達約50%與70-80%，氨氮因硝化作用與植物吸收致使去除率高達98%。綜合上述，鹿角溪及打鳥埤人工溼地可有效削減污染物，且BOD、營養鹽及TC之去除率分別達約50%、85%與97%。

This study evaluates the performance of pollutants reduction in Lujiao creek and Daniaopi constructed wetlands (CWs) in New Taipei City. Both CWs contained 5 treatment basins. The data of water quality and flow rate of CWs monitored from 20013 to 2014 was collected. The purposes of this study were (1) to evaluate performance of pollutants reduction by CWs, (2) to examine the relation between influent pollutant loading and removal rate, and (3) to analyze pollutant removals in treatment basins. Water quality items included biochemical oxygen demand (BOD), ammonium nitrogen (NH3-N), total nitrogen (TN), total phosphorus (TP) and total coliform groups (TC). Furthermore, the box and whisker plot median and effluent probability method (EPM) were used to determine the performance of pollutants reduction. 
The result showed that the hydraulic retention time and hydraulic loading rate of Lujiao River CW were 19 days and 0.02 m/day, respectively. Those were 14 days and 0.05 m/day for Daniaopi CW. The removal rates of BOD, NH3-N, TN, TP and TC calculated by EPM were 47.5%, 99.9%, 85.1%, 85.6% and 97.5%, respectively. The removal rates determined by the Box and whisker plot median were almost the same with that by EPM.  Pollutant removal rate has a good linear relationship between inflow pollutant loading with determination coefficient (R2) values of BOD、TN、TP ranged from 0.87 to 0.99. Thus, the relationships could be used to design CWs. Moreover, the removal rates of BOD and nutrients (TN and TP) at third basin of CWs could reach to approximately 50% and 70-80%, respectively. Due to nitrification and plants uptake, the removal rate of NH3-N reached up to 98%. It is concluded that Lujiao creek and Daniaopi CWs effectively reduced pollutants and the removal rates of BOD, nutrients and TC about 50%, 85%and 97%, respectively.
