由於台灣人口密集民生用水需求量大，若能利用民生放流水進行回收，再經妥善再生後將可成為一種輔助與備載水源且能分擔主要用水需求。目前來說，再生回收水是一種新興的管理與應用，若能適當監控與處理，其能有效減少環境中的污染物、降低成本及環境回饋。
本研究利用粒狀生物活性碳濾床處理鳳山溪民生放流水，觀察民生放流水中有機碳之去除效率。由實驗顯示，有機碳濃度隨著空床停留時間的增加，去除率隨之上升，其中TOC與DOC平均最佳去除效率於72% 與78% 左右。比較不同溫度下粒狀活性碳之TOC去除效率方面，實驗前段粒狀活性碳於室溫(25℃)與4℃下TOC之去除效率分別為95 % 與90%；實驗後段為 85 % 和 80 % ；DOC之去除效率於實驗前段分別為95% 與90%；實驗後段為90 % 和 87 %，即可發現室溫(25℃)處理有機碳比4℃下來得好。
於系統處理水與再生水水質標準比較方面，水質參數(水溫、懸浮固體物、BOD、COD、pH)皆能符合再生水水質標準。不過由於本系統採用生物活性碳濾床處理，處理水中溶氧容易下降且導電度也不會有所影響，故該兩項水質參數普遍未符合水質標準。
另外，將馴養後之粒狀活性碳經由SEM照攝下發現室溫(25℃)馴養下之粒狀活性碳表面生物膜面積較4℃下來得多，從對應有機碳之去除效率來看，其去除效率也較4℃來得高。由此可知，生物膜面積與有機碳之去除效率具有一定的關係。

Because of high intense population is in Taiwan, households water use requires a considerable amount. It is substantially reduce daily water use to share primary water resources, if we can reclaim domestic wastewater properly and make it support. Currently, reclaiming water is an emerging requirement for management and application. If we can adequately monitor and treat reclaimed water, reducing environmental contaminants, costs, and environmental feedback is possible.
The study treated domestic wastewater of Feng-Shan river using GAC trickling filter with two column in a series and the removal efficiency of organic carbon was observed. The experimental results indicated that removal efficiency of organic carbon concentration was decreased as the empty-bed contact time (EBCT) increased. The best average removal efficiency of TOC and DOC was about 72% and 78%. According to the TOC removal rates using GAC at different temperatures, the TOC removal rates at room temperature and 4℃were respectively 95% and 90% in the first column of the experiment and 85% and 80% in the second column. The removal rates of dissolved organic carbon (DOC) using GAC folter system at room temperature and 4℃ were respectively 95% and 90% in the first column of the experiment and 90% and 87% in the second column. Obviously,the TOC removal rate treated using GAC filter system at room temperature was superior to that treated at 4℃
In comparing treated water and recycled water,most of the water quality parameters (temperature、Suspended solids、BOD、COD、pH) were to meet recycled water quality standards.However, the system due to use GAC trickling filter system treatment that easily decrease dissolved oxygen in treated water but conductivity in treated water without changes. These two water parameters were failed to meet the recycled water standards.
By the way, we found trained GAC through SEM irradiation the biofilm area of trained GAC surface at 25℃was superior to that treated at 4℃. It corresponds to the removal efficiency of organic carbon, the removal efficiency of 25℃ was higher than result of 4℃. Therefore, a certain relationship between the biofilm area and removal efficiency of organic carbon is existed in this work.
