• 中文摘要： 本文之主要目的係以人工廢水為對象，探討在各種不同操作策略情況時，其對連續回分式生物反應槽處理效果的影響。根據試驗結果顯示，連續回分式生物反應槽若每日處理水量一定，則每日處理回數愈少，污泥的沈降性愈佳”此外，若有部分進水時間，不論是間歇式或連續式不曝氣，均可改善放流水水質和污泥沈降性。同時，本文所探討的12種不同操作策略，其處理效果顯示，放流水之COD和SS濃度均隨進流水有機負荷成線性增加關係，且COD的去除率，在本研究所探討的有機負荷範圍內，均可維持在88至98％間，此顯示連續回分式生物反應槽可達到很好的處理效率。更進一步地，由於連續回分式生物反應槽在進水階段有調勺的功能，故能容忍突增有機負荷而不會影響放流水水質，一般而言，在循環突增有機負荷的情況，COD的去除率仍可維持在90%以上，且污泥的沈降性不受影響。
• 英文摘要： The main purpose of this study was to investigate effects of various operating strategies on the per-formance of sequencing batch biological reactors (SBR) for treating synthetic wastewater. According to theexperimental results, for treating an equal volume of wastewater each day, the SBR unit operated with alower daily cycle number resulting in better sludge settleability. In addition, strategies with a portion of fillintermittently or continuously unmixed and unaerated can improve the effluent quality and sludge settle-ability. Also, results of 12 different types of operating strategies carried out in this study indicate thateffluent COD and SS increased linearly with an increase in influent organic loading, while COD removal ratioswere kept in the range of 88 to 98%, indicating high treatment efficiency of the SBR system. Further, due tothe fact that an SBR tank can serve as an equilization basin during fill, SBR's can tolerate shock loads ofCOD without degradation in effluent quality. In this study, the COD removal ratio was still above 90% andsludge settlability was unaffected in the case of cyclic shock loading.
