中文摘要 | 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(porous WAS pellets)及曝氣石,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,(SND 效率 98 % > 92%)。 |
英文摘要 | 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 porous 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 porous WAS pellets. The pellets reused in sequencing batch biofilm reactor (SBBR) as diffuser and can attach biofilm and enhance the wastewater nutrient removal efficiency. The simultaneous nitrification denificcation (SND) efficiency removal results of SBBR with rebuilt WAS pellets are better than that of the traditional SBR system (with 98 % and 92%, respectively). |
