Abstract

Abstract: At normal temperature(20±1)℃,SBRs have been used for treating actual domestics wastewater with low C/N ratio,and the start-up and N₂O emission of nitrosation process in modes of continuous aeration SBR(SBR1) and intermittent aeration SBR(SBR2) investigated. The DO in SBRs should be controlled at comparatively low level, and the aeration should be stopped at the time of pH ammonia valley point. The results show that both modes could achieve nitrosation process,after continuous and intermittent aeration modes were operated for 100 d and 75 d,respectively. It is easier to realize nitrosation process in intermittent aeration mode. The N₂O conversion rates in continuous aeration mode and intermittent aeration mode are 12.2% and 8.10%,respectively. The aerobic denitrification process of AOB is the main path of N₂O emission. The anoxic stage in intermittent aeration(SBR2) mode can reduce the NO₂^- accumulation in aerobic stage,and reduce the substrate concentration in aerobic denitrificaiton process and N₂O emission as well.

Key words: continuous aeration, intermittent aeration, nitrosation, N₂O, aerobic denitrification

摘要： 在常温下[（20±1）℃]利用SBR反应器处理低碳氮比实际生活污水，考察连续曝气和间歇曝气方式下亚硝化过程的启动及N₂O的释放。控制SBR反应器DO处于较低水平，并在pH"氨谷"点出现时停止曝气。结果表明，连续曝气和间歇曝气方式分别运行100、75 d后均实现了亚硝化过程。间歇曝气方式下更易实现亚硝化过程。连续曝气和间歇曝气模式下的N₂O转化率分别为12.2%、8.10%。AOB的好氧反硝化过程是N₂O释放的主要途径。间歇曝气模式下的缺氧阶段能够减少好氧段NO₂^-积累，降低好氧反硝化过程底物浓度，减少N₂O释放。
