摘要
近幾年來水質保護一直是備受矚目焦點，家庭污水及畜牧廢水為國內主要水污染來源，如果直接排放會造成河川水質遭受污染。台灣目前生活污水的處理，主要是經由污水下水道系統，統一排放至大型污水處理廠處理，其內政部營建署100年11月的統計目前公共污水下水道系統普及率為28 %，表示有多餘七成之生活污水是直接排放至承受水體。現今台灣的畜牧廢水，大多採用三段式廢水處理系統來處理，但建造成本成本較大，如生活污水及畜牧廢水均SFBS系統處理，將可節省大量成本。
本研究採用專利技術SFBS模場設備，以穩流生物技術處理生活污水與畜牧廢水之研究，本研究主要是測試本系統在不同的污染負荷下的去除率、並針對去除狀況進行探討。
研究結果顯示生活污水經系統處理後COD之去除率平均在80%；SS之去除率平均在79 %； TN之去除率平均在63%；NH3之去除率平均在85%；TP之去除率平均在49% 。養豬事業廢水經系統厭氧與好氧處理後其COD之去除率平均在95%；SS去除率平均在97%；BOD去除率平均在98%；出流水pH平均值為7.76；出流水溫度平均值為28.0℃；出流水ORP平均值為-142 mv，TN之去除率平均在77%；NH3之去除率平均在88%，TP之去除率平均在89%。
目前減少資源浪費為全球所共同追求之目標，針對實際廢水處理與操作，在良好情形下，去除率相對提高，此設備與一般廢水處理系統比較，成本較低且佔地空間小，符合全球共同追求之目標。

Abstract
In recent years, water quality protection has been a widespread concern. Domestic waste water and livestock waste water is the main source of domestic waste water, and direct discharge will pollute river and lake quality. In Taiwan, the current domestic waste water is discharged to the sewers and treated by the large-sized waste water treatment plants. The popularity rate of current public sewage system by the Construction and Planning Agency, Ministry of the Interior, as of November 2010 is 28%, indicating that more than 70% of domestic wastewater is directly discharged into the receiving waters. The livestock waste water in Taiwan is treated by three-stage treatment system and the construction cost is high. If the domestic waste water and livestock wastewater is treated by Steady Flow Biological System (SFBS), large costs can be reduced.
This study used SFBS plant equipment and steady flow biological system to treat domestic wastewater and livestock wastewater. This study aimed to test removal rate of the system under different pollution loads and discuss the removal conditions.
The findings showed that COD removal rate is 80.0% after treatment of domestic waste water; removal rate of SS is 79.8% on the average; the average removal rate of TN is 63.9%; the average removal rate of NH3 is 85.9%; the TP removal rate is 49.3% on the average. Average COD removal rate of the swine wastewater system is 95.53% after anaerobic treatment and aerobic treatment; average SS removal rate is 97.69%; average BOD removal rate is 98.28%; the pH of the outlet water is 7.76; the average outlet water is 28.0℃; average ORP of outlet water is -142 mv, and average TN removal rate is 77.83%; average NH3 removal rate is 88.84%, and average removal rate of TP is 89.45%.
Currently, elimination of resource waste is the global goal. In treatment and operation of actual waste water, removal rate is relatively increased under the good conditions. As compared to the common waste water treatment system, this equipment has low cost and occupancies small space, conforming to the global goal.
