摘要傳統活性污泥是目前最常用的廢水處理方式之一，但此方法會產生大量廢棄活性污泥，間接製造出廢棄物處理的問題，因此本研究以資源回收處理的方式燒製載體，來回收廢棄的活性污泥餅。在本研究中，採用內湖污水處理廠所產生之廢棄活性污泥，與紅土以及少量化學添加物以一定比例混合，燒製成載體（rebuilt WAS pellets），將此載體利用於循序批分式反應槽（SBR）中，藉由生物膜的形成以增加廢水處理效率，由實驗結果得知，添加此載體之反應槽處理（SBBR）效果較未添加任何載體之反應槽處理效果為佳（KN 和 KDN 分別為 10.6 mg-NH4+-N/L-hr和10.4 mg-NO3--N/L-hr皆高於未添加任何載體之反應槽5.3 mg-NH4+-N/L-hr 和5.0 mg-NO3--N/L-hr），添加此載體之反應槽同時硝化脫硝效果較添加市售載體為佳（SND效率99 % > 92%），本研究並利用反應槽中氧化還原電位（Oxidation Reduction Potential, ORP）之變化，推導出適用於線上即時控制同時硝化脫硝（Simultaneous Nitrification and Denitrification, SND）之模式。 Abstract Traditional activated sludge generates large amount of wasted activated sludge (WAS) and need excess cost to deal with. The ways to reduce the amount of WAS certainly will contribute to the cost down in treatment system. Therefore, this study attempts to recycle the wasted activated sludge cake and bake into immobilized pellets then add to the SBBR system. In this study, the WAS from Nei-Hu wastewater treatment plant mixed with red soil and some chemical additives to bake as the rebuilt WAS pellets. The pellets reused in sequencing batch biofilm reactor (SBBR) to attach biofilm and enhance the wastewater nutrient removal efficiency. In the SBBR system with rebuilt WAS pellets, the KN and KDN are 10.6 mg-NH4+-N/L-hr and 10.4 mg-NO3--N/L-hr which are higher than 5.3 mg-NH4+-N/L-hr and 5.0 mg-NO3--N/L-hr in the traditional SBR system. The SND efficiency removal results of SBBR with rebuilt WAS pellets are better than that of the SBBR with commercial pellets (with 99 % and 92%, respectively). The simulated ORP Nernst model can be applied to the real time control of the SBBR system to treat nutrient substrances.
