  人工溼地是省能源、低成本且自然的汙水整治系統,能有效的移除不同的汙染物,例如懸浮微粒、氨氮、有機物及重金屬等,在各地都已廣泛的被使用。其處理過程牽涉了物理、化學及生物做用而變的複雜,因此為了增進汙染物的移除效率,一份對於單一人工溼地詳細的研究是必須的。
本研究中的目標為位於嘉義縣的荷苞嶼人工濕地一期,其為由三池所串聯的表面水自由流動式人工溼地。我們延著水流方向依序採樣,並透過水化學分析、統計分析及水化學模擬,來了解汙水在濕地中各處理池中汙水地球化學性質的改變。
  水化學分析的結果顯示延著水流方向,水中的溶氧量確實的增加,根據前人研究可知,溼地中的水生植物能帶來氧氣與有機物質。在本研究中COD、氨氮、磷酸鹽、錳和鐵的高移除率(50%-100%)。另一方面,水化學模擬的結果顯示在水體和沉積物之間有鈉及鉀、鈣及鎂等陽離子的離子交換行為。此外,在荷苞嶼人工濕地中,鐵和錳是以赤鐵礦(或氫氧化鐵)和軟錳礦(或氫氧化錳)沉澱的方式移除;因此多數的金屬離子能透過被赤鐵礦及軟錳礦吸附而移除,然而砷和鈾卻呈現負移除的結果。根據熱力學模擬,砷和鈾是以帶正電的化合物存在於中性至鹼性的水體之中,因此不易被同帶正電的氫氧化物移除。統計分析的結果顯示,濕地中與汙染物移除最相關的環境參數為pH值,pH值的提高主要是由於濕地中大量的水生植物行光合作用的結果。

  Constructed wetland (CW) is a cost-effective natural system and can remove considerable amount of various pollutants, such as suspended solid, ammonia, organic carbon and heavy metals. It has been extensively applied in wastewater treatment. CW is a complicated system which involves physical, chemical, and biological process. To increase the pollutant removal efficiency, a detailed study on an individual CW is necessary. The Studied CW, named as Hebao Island free water surface CW, is located in Chiayi County, Taiwan. It is composed of 3 units. In this study, the water samples were sequentially collected along the flow path to determine the geochemical evolution with hydrochemical analyses, statistical analyses and aqueous geochemical modeling.
  The results of hydrochemical analysis demonstrate considerable increase of dissolved oxygen along the flow path. It is believed that aquatic plants bring in both of oxygen and organic matter. However, high removals (50%-100%) of COD, ammonia, phosphate, manganese and iron can be observed in this study. On the other hand, the aqueous geochemical modeling shows considerable cation exchange of Na+K and Ca+Mg between water and sediment. In addition, iron and manganese in Hebao Island are removed by the precipitation of hematite (or iron hydroxide) and pyrolusite (or manganese hydroxide); therefore, most of heavy metals could be removed by being absorbed by hematite and pyrolusite. However, arsenic and uranium demonstrate opposite trend with negative removals. According to the thermodynamic simulation, arsenic and uranium are positive-charged compounds in a neutral to alkaline water and would not be removed by positive-charged hydroxides. The results of statistical analysis demonstrate that the removals of pollutants are dependent on pH value of water which could result from photosynthesis process.
