摘要
试验采用曝气-搅拌-曝气相结合的间歇曝气SBR工艺处理模拟废水,探讨不同有机容积负荷条件下,系统对COD、TN与TP的处理特性,并进行相关动力学研究。结果表明,0.70-1.96 kg COD/(m3·d)有机容积负荷范围内,系统COD、TN与TP去除率随负荷无明显变化趋势,处理效果稳定,耐冲击负荷。在所有运行期间,系统COD、TN与TP平均去除率均大于96%,处理效果显著。据试验所得,在0.70-1.96 kgCOD/(m3·d)有机容积负荷范围内,间歇曝气SBR工艺COD降解动力学模型为[(So-Se)·Q]/XV=(1.31×Se)/(194.96+Se),TN降解动力学模型为[(So-Se)·Q]/XV=(0.02×Se)/(3.42+Se)。
The simulated wastewater was treated in SBR with intermittent aeration contained three parts： aeration-stirring-aer- ation. Study on the removal characteristics of COD, TN, TP and the kinetics at different organic volume loading in the system. At 0.70-1.96 kgCOD/（m^3·d）, the removal efficiency of COD, TN, TP had no significant trends with the changing of organic volume loading, the removal efficiency was stable and the system was anti-shock loading. In the whole stages, the average removal efficiency was over 96% in the system so the removal efficiency was significant. At 0.70-1.96 kgCOD/（m3·d）, the kinetic model of COD was[（So-Se）·Q]/XV=（1.31×Se）/（194.96＋So） and TN was [（So-So）·Q]/XV=（0.02xSo）/（3.42＋Se） in the SBR with intermittent aeration.
