以人工溼地系統處理廢水為一自然淨化程序，與傳統之廢水處理系統做比較，具有省能源、低成本、無須添加化學藥劑、操作及維護簡單等優點；同時，又能提供生態棲息空間、自然景觀等釵h弁遄A故人工溼地系統在水資源技術上具其經濟效益，為一個值得探討其應用價值的自然處理方法。
本研究利用嘉南藥理科技大學小型人工溼地實驗模場所建立之數據，探討已操作三年之表面流動式系統(FWS)與表面下流動式系統(SSF)及生態池三個不同系統中在氧化還原電位(ORP)與溶氧(DO)、酸鹼值(pH)、生化需氧量(BOD5)、化學需氧量(COD) 及氨氮(NH4-N)之關係。結果指出，校園生活污水進入FWS型溼地系統後，水體中溶氧濃度會增加，氧化還原電位有提高之傾向，兩者均維持在3~4mg/L與0~150mV之間；而進入SSF型溼地系統後，溶氧濃度與氧化還原電位皆呈現一個不穩定的現象。pH值在進入溼地系統初期為弱鹼性，經FWS型溼地系統可能進行硝化作用而轉為中性，進入SSF型溼地系統後，有限氧氣可能讓硝化作用受到限制，使pH值轉為弱酸性。生化需氧量與化學需氧量經由FWS型系統處理後有減少的趨勢，即有去除效果；但污水進入SSF型溼地後，可能因氧氣量有限，使去除效果有減緩。污水進入FWS型溼地系統後，水體中氨氮濃度有逐漸減少；進入SSF型溼地系統後，氨氮濃度降低，大部分在5mg/L以下之間。生態池除了可作為人工溼地處理污水後的水質監測，與FWS型溼地有相同效果，對水體進行穩定化處理。將本研究中氧化還原電位與溶氧、酸鹼值生化需氧量、化學需氧量及氨氮之關係，經由線性迴歸後發現相關性不佳，推論可能原因為本系統為一開放性且系統複雜所導致，與文獻所述單一系統不同。

Comparing the traditional wastewater treatment system, the constructed wetlands(CW) system not only is a natural process for purifying the waste water, but also has the advantages of saving energy, low cost, no chemicals added, simple operation and maintenance. At the same time, it also can provide many functions, i.e. ecological space, natural landscape, and education, etc. Therefore, the CW system, a natural treatment method, possesses the economic benefit on wastewater treatment and water resource reuse.
In this study, the relationships between Oxidation Reduction Potential(ORP) and the pollutants in CW system will be investigated, which are based on the pilot-scale CW system in Chia-Nan University of Pharmacy and Science. This pilot-scale CW system has been operated for four years, and has three parts of free water surface(FWS) system, subsurface of water(SSF) system, and ecotype pond. The results showed that the ORP increased as the DO value increased when the campus wastewater existed in FWS system, both values of ORP and DO kept in the range of 0-150 mV and 3-4 mg/L, respectively. However, both ORP and DO appeared the unstable phenomenon while the wastewater entered the SSF system. The pH value was weak alkaline in the initial stage of the CW system, but it would transfer into neutral in FWS system and acid weakly in SSF system. The BOD5, COD, and ammonia nitrogen all reduced when the wastewater stayed in the CW system, but the removal efficiency was lower in the SSF system. All the results correlative to ORP might be caused by the vicissitudes of DO in the water body. The ecotype pond had the functions of monitoring and stabilizing the water quality after the CW system. The linear statistic analysis was also used to investigate the relationships between ORP and the concentrations of pollutants. The results showed they were not good linear relationships like the reports. This would be due to the CW system is operated in open and complicated environment, not a simple and controlled system.
