Among the economic crops, pachyrhizus leaf had the most remarkable treating effect, the COD treating capacity per day per unit area was 4.01g, that is, a 50% treating rate; the BOD treating capacity was 1.15 g, that is, a 35% treating rate; the TP treating capacity was 0.23 g, that is, a 16% treating rate; the TN treating capacity was 1.87 g, that is, a 74% treating rate; however, the treating effect decreased as the total amount of pollution entering this system increased by raising the water volume, which was mainly owing to the relatively short hydraulic retention time.

由水质试验结果显示，本系统所选用的作物处理生活污水成效极佳，优於一般湿地选用的植物，以及河滩地原生草种型态，其中以地瓜叶的处理成效最为显著，每日单位面积COD去除速率为4.01 g 、处理效率达50﹪；BOD去除速率为1.15 g 、处理效率达35﹪；TP去除速率为0.23 g 、处理效率达16﹪；TN去除速率为1.87 g 、处理效率74﹪，而以加大水量的方式，增加进入本系统之污染总量，其处理成效减低，主要原因受到水力停留时间较短影响，未来可以增加处理面积、水力停留时间加长、提高原水浓度为后续之研究方向，以达到增加本系统处理成效之目的。
