Abstract:	本研究係利用廢棄尿布中之不織布所製成之微生物擔體，構建一嶄新之附著式好氧性生物處理系統，現場處理台南市立文化中心景觀池水，評估此新式處理方法之適用性，併探討程序操作因子對處理效率之影響。本系統採連續性進水處理192天，處理後之池水再排回原水體，以達到的節能省水之目的。本研究主要評估擔體數量與水力停留時間對系統處理效率之影響。研究發現，當擔體數量相同時，出流水水質以水力停留時間3小時為最佳。研究結果顯示，本系統對濁度、懸浮固體物、COD、葉綠素-a及總磷的去除效果極佳，去除率最高分別可達到95%、99.9%、90%、96%及98%；由氮化物之平衡計算得知，本系統對於氮化物之去除效率約為55%。擔體填充率方面，以體積填充率為0.92%（4800個擔體）之實驗組別處理效果較佳；值得一提的是，本系統所使用之微生物擔體體積填充率平均僅需介於0.62〜0.92%之間，即可得到上述的處理效果。本研究回收使用尿布不織布為池水處理之微生物擔體，研究結果顯示，利用本工法處理受污染池水俱極佳之成效，施工與系統操作維護簡易，可考慮做為未來受污染池水處理暨回收之替代方案。 In this study, an innovative contact aeration process was constructed at Tainan municipal culture center for pond water treatment. The aims of this study are to evaluate the feasibility of a new microbial carrier and to evaluate the system efficiency. The microbial carrier employed in this study was prepared from non-woven material which was obtained from waste diaper. A continues operation was carried out for 192 days and the effluent was discharged to the pond for water recycling. This study mainly examined the effects of two parameters including carrier quantity and hydraulic retention time (HRT) on the system performance. The result of the study indicated that the best effluent quality was found with a HRT of 3 hours when the same number of carrier was employed in different runs. The highest removals on turbidity, suspended solid, chemical oxygen demand, chlorophyll-a and total phosphorus was observed and the efficiency were 95, 99.9, 90, 96 and 98%, respectively. The result of the nitrogen mass balance calculation also revealed that the nitrogen removal of 55% was achieved. As for the carrier packing ratio, a volumetric ratio of 0.92% could lead to the best system performance. One thing should be noted was that the carrier packing ratio adopted in this study was with a range of 0.62 - 0.92%. The low packing ratio means that this system is with the advantages of space saving and could be as a practical technology for pond water treatment. This study recycled the non-woven material obtained from the waste diaper as the microbial carrier for the treatment of pond water. The results showed that this technology was cost-effective to produce and establish, robust, efficient, and easy to operate and maintain. Therefore, this innovative technology could be considered as an alternative for the treatment of polluted pond water in the future.
