以人工溼地系統處理校園污水為一自然淨化程序，不需添加化學藥劑，且操作、維護簡單，應用於污染物單純之校園污水的處理；人工溼地系統除具備廢污水處理及再利用功能外，更具教育功能。
本研究以台灣師範大學校園溼地為研究對象，探討污染物的去除效率。從2005年1月到2006年5月的偵測期間，各污染物的平均去除率：化學需氧量(72.2%)、生化需氧量(68.3%)、氨氮(93.8%)、懸浮固體(65.2%)、正磷酸鹽(88.5%)、大腸桿菌群和糞生大腸桿菌群(98.5%)。與文獻相比，有較高的去除效果，可能是由於水力負荷率較低，水力滯留時間較長，有充裕的時間去除污染物。
實驗期間以流量大小可區分成兩階段，2005/1-2005/7的平均流量為0.35m3/d，2005/8之後將平均流量調整為2.99m3/d。當污水的平均流量提高時，去除率會有部分的下降。
人工溼地的負荷率對污染物的去除量呈現高度正相關，提高污染物在溼地中的負荷率，雖然去除率稍降，但單位面積的去除量上升；從溫度對污染物的去除速率常數之影響，推測氨氮去除的主要機制為生物活動，磷主要經由介質吸附和化學沉澱而去除。化學需氧量及生物需氧量大部分組成可能是顆粒態，可經由過濾而去除。
根據衞生檢驗級分系統，人工溼地放流水中的糞生大腸桿菌分佈較大的區間為10-99，此濃度範圍為中度風險；化糞池出流水經人工溼地處理之排放水水質，根據陸域地面水體分類，符合分類丁，適用於灌溉用水、二級工業用水(冷卻用水)及環境保育。

As an environmentally friendly wastewater treatment process, constructed wetlands has advantage of easy to operate, low energy input, extra wildlife habitant, and groundwater replenishment.
In this study, the constructed wetland in National Taiwan Normal University in treating septic tank effluent was monitored. The average removal efficiency during first two-year operation period are: COD (72.2%)、BOD5 (68.3%)、NH4+-N (93.8%)、S.S. (65.2%)、PO43--P (88.5%)、TC and FC (98.5%). Compared with literatures, mostly better removal efficiency may be because of lower loading and longer hydraulic retention time.
The operation period could be divided into two phases with high and low flow rate. Higher pollutant loading led to higher removal per unit area and lower removal efficiency. The first-order removal rate constant of pollutants depended on temperature. However, removal rate constants of COD、BOD and phosphate were not significantly sensitive to temperature changes. It implied that the main removal mechanism of COD、BOD and phosphate in constructed wetland might be filtration and sediment, not biological activities.
According to sanitary inspection risk score, fecal coliform in the effluent of constructed wetland was categorized as class C. Further treatment may be needed in case the effluent is for reuse.
