摘要
在传统SBR反应器中悬挂悬浮填料用于处理畜禽废水,研究该系统处理畜禽废水的最佳工艺参数及运行模式,结果表明:当MLSS维持在2000～2500mg/L、曝气时间为5h时,系统对畜禽废水的处理效果最佳;在该条件下,采用交替好氧/缺氧运行模式出水中COD、TP、NH3和TN的去除率分别由原来传统SBR运行模式的93.21%、65.33%、84.75%、79.35%提高到94.21%、65.87%、88.83%、82.68%。
This research investigates the optimum technologic parameters and running model in classic SBR, inside which the suspended filler is installed. The result reveals that the best effect was obtained when MLSS stayed at 2000-2500mg/L and aeration time was five hours and that for the same situation, when alternating aerobic/anoxic technology was used, the removal efficiency of COD, TP,NH3 and TN increased to 94.21%, 65.87%, 88.83% and 82.68% respectively from 93.21%, 65.33%, 84.75% and 79. 35% of the classical SBR running model.
