中文摘要 | 本文針對厭氧好氧活性污泥程序提出一新的整合性參數q□(比殘留基質利用率), 並藉以解釋在各種不同污泥停留時間SRT(5,10,15天)及反應槽厭氧、好氧段體積比例V □/V□(1:9,1:4,1:2.3)之交互影響下,同時除磷及抑制膨化之程序需求。寶驗結果顯示 以比釋磷量作為膨化抑制「代謝選擇」機制之評估方式,在不同SRT及V1□/V□之情形下, 未能展現其解釋上之一致性。然而SVI均與q□呈現良好之線性關係。由此結果顯示由厭氧 段殘留之基質於進入好氧段後之利用情形,方為影響膨化之最主要因子。因此欲以厭氧好氧 程序同時除磷及抑制膨化,在任何SRT情形下反應槽之設計應儘可能使q□最低為原則。基 於上述結論,本文以q□整合除磷及抑制膨化之需求,配合模式觀念提出厭氧好氧活性污泥 系統之設計程序。 |
英文摘要 | The simultaneous process requirements of phosphorus removal and bulking control are demonstrated in this study via an introduction of the integrated parameter q□, i.e., specific residual substrate utilization rate. Pilot-plant experiments using synthetic wastewater were performed at different SRTs (5, 10, 15 days) and anaerobic:aerobic volume ratios, V□:V□ (1:9, 1:4, 1:2.3). These results indicate that sludge settling properties in terms of SVI vary significantly, and a higher phosphorus removal does not necessarily imply a better sludge settling. Nevertheless, SVI-values highly correlate with q□, implying that eliminating the access of filaments to substrate plays a more influential role on SVI than favoring the poly-p microorganisms. Based on these findings a design procedure of anaerobic/aerobic process for simultaneous requirements of phosphorus removal and bulking control are proposed by the introduction of the parameter q□. |
