摘要
Abstract
[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.关键词
