摘  要：
[目的]研究SBR反应器中好氧颗粒污泥处理模拟废水的反应特性。[方法]将SBR好氧颗粒污泥反应器应用于模拟废水的处理,研究反应器中溶解氧随曝气强度的变化规律,并探讨一个反应周期内COD、TN、TP去除率的变化。[结果]不同曝气强度下,SRB反应器开始曝气时(第11 min)溶解氧值均最低,之后呈上升趋势,均在第13 min出现第一个"平台",且曝气强度越大,该"平台"越高;50min后溶解氧值波动较小。反应周期结束时,不同气速下COD、TN、TP去除率分别达98%、75%、80%以上,且不同气速对污染物的去除有一定影响。[结论]该研究为今后废水处理工程的实际应用提供了技术指导。

摘  要：
[Objective] The aim was to study the response characteristics of simulated wastewater treated by aerobic granular sludge in SBR reactor.[Method] Wastewater was treated by aerobic granular sludge in SBR reactor,then the changes of dissolved oxygen(DO) in SBR reactor with aeration intensity were studied,and the variation of removal rate of COD,TN and TP during a response period was discussed respectively.[Result] Under different aeration intensities,the concentration of DO was the lowest when aeration was begun in SBR reactor(namely the 11th min),then showed increasing trend;the first "platform" appeared at the 13th min,and rose with the increase of aeration intensity;after 50 min,the concentration of DO was stable.At the end of response period,the removal rate of COD,TN and TP under different aeration intensities reached above 98%,75% and 80% respectively,and various aeration intensities had certain effects on the removal rate of pollutants.[Conclusion] The study could provide technical guidance for the practical application of wastewater treatment project in the future.
