    摘要: 在自然的生態系統中溼地是最重要的組成。溼地的主要弁鄍]括維持和再回收營養物質,野生生物棲息地、穩定海岸線、控制和緩衝自然的溢流、再補注地下水,提供污染物質在水中的處理。當污染物質進入一個溼地的時候,他們可能在溼地裡被生物品種利用或者以沉澱方式固定,所以溼地系統時常被應用在把污染物質從水中移除。
    本研究是運用人工溼地系統,經由種植不同種類植物來處理除草劑,草脫淨(atrazine)和二,四地(2,4-D),並且討論除草劑對人工溼地的影響。人工溼地系統包括有表面流動型溼地及表面下流動型溼地以並聯方式連接。結果顯示, 含 atrazine 人工溼地 FWS 系統中氨氮(NH4-N)、硝酸鹽(NO3)、磷酸鹽(PO4-P)、atrazine 總平均去除效率分別為 97.1~98.3%、40.43~80.85%、87.8~95.1%、90%~99%。SSF 系統中,氨氮(NH4-N)、硝酸鹽(NO3)、磷酸鹽(PO4-P)、atrazine 總平均去除效率分別為 96.1~97.4 %、64.89~86.17 %、85.1~90.4 %、90~99 %。
    在含 2,4-D 人工溼地FWS系統中氨氮(NH4-N)、硝酸鹽(NO3)、磷酸鹽(PO4-P)、2,4-D 總平均去除效率分別為 96.8~97.1 %、51.61~86.02 %、94.3~96.1 %、61~71%。SSF 系統中氨氮(NH4-N)、硝酸鹽(NO3)、磷酸鹽(PO4-P)、2,4-D 總平均去除效率分別為 98.1~98.5 %、63.44~87.10 %、92.7~95.3 %、66~72 %。
    Wetlands are among the most important components in natural ecosystems. The major functions of wetlands include holding and recycling nutrients, wildlife habitats, stabilizing shorelines, controlling and buffering natural floods, recharging groundwater, providing treatment for pollutants in water. When pollutants enter a wetland, they may be utilized by the biological species inside the wetland or settled in the sediments so that the wetland systems are often applied in removing pollutants from water.
    This research was used constructed wetland (CW)systems which planted different macrophates to treat herbicide, atrazine and 2,4-D, and discussed the effects in the CW systems. The CW systems including a free surface flow (FSF)wetland and a subsurface flow (SSF)wetland which connected in parallel. The results showed the average removal efficiency of NH4-N, NO3, PO4-P, atrazine for the CW systems including atrazine in FSF system were 97.1~98.3%、40.43~80.85%、87.8~95.1%、90%~99% respectivety. The average removal efficiency of NH4-N, NO3, PO4-P, atrazine for the CW systems including atrazine in SSF system were 96.1~97.4 %、64.89~86.17 %、85.1~90.4 %、90~99 % respectivety. The average removal efficiency of NH4-N, NO3, PO4-P, 2,4-D for the CW systems including 2,4-D in FSF system were 96.8~97.1 %、51.61~86.02 %、94.3~96.1 %、61~71% respectivety. The average removal efficiency of NH4-N, NO3, PO4-P, 2,4-D for the CW systems including 2,4-D in SSF system were 98.1~98.5 %、63.44~87.10 %、92.7~95.3 %、66~72 % respectivety.
