中文摘要 | 本研究利用一系列批次實驗以了解不同厭氧反應時間對於脫硝除磷菌 ( denitrifying phosphate accumulating organisms )佔總磷菌( phosphate accumulating organisms )百分率的影響, 研究結果顯示脫硝除磷菌佔總磷菌的百分比會 隨著厭氧反應時間的增加而增加, 其原因可能是因為脫硝除磷菌體內 PHA ( polyhydroxyalkanoates )於厭氧下之累積速率會較單純除磷菌( non-denitrifying phosphate accumulating organisms )於厭氧下累積 PHA 的速率慢,因此,脫硝除磷菌需 要較長的厭氧反應時間以達到其飽和的 PHA 累積量,相反的, 單純除磷菌所需要達到飽和 PHA 累積量的時間則較短。此外,由實驗結果亦可得知若要針對加強脫硝除磷菌存在之營養 鹽去除程序設計時,其厭氧水力停留時間必需要大於兩小時,以確保脫硝除磷菌有足夠的時 間進行碳源的攝取及 PHA 的累積。 |
英文摘要 | This study investigated the influence of anaerobic reaction time on the fraction of denitrifying phosphate accumulating organisms (DNPAO) to total phosphate accumulating organisms (PAOs) using a series of batch experiments. The results showed that the DNPAO increased as the anaerobic reaction time increased. This implied that the PHA (polyhydroxyalkanoates) accumulating rate of DNPAO was lower than that of non-denitrifying phosphate accumulating organisms (non-DNPAO). Thus, the DNPAO required a longer anaerobic reaction time to reach the saturated intracellular PHA level. Furthermore, more than two hours of anaerobic hydraulic retention time is necessary when designing an enhanced DNPAO process. |
