| 摘 要： | 采用两相厌氧/好氧工艺处理东北某肉业公司屠宰加工废水.研究不同反冲洗方式和条件对系统处理效果的影响.结果表明,反冲洗后二级BAF的COD去除率大约经过4h左右恢复到反冲洗之前,二级BAF的SS去除率大约经过4～8h恢复到反冲洗之前.适当的反冲洗策略不但可以恢复生物膜的活性,改进系统的出水效果,还可以延长反冲洗周期,减少...

| Abstract: | Two stages biological aerated filter（BAF） system was used to treat meat packing wastewater.The effects of back-washing models on system performance were investigated.The results show that the optimal gas/water ratio is 2/1 and the favorable pollutants removal efficiency is achieved when this ratio was applied.The results show that the time for COD and SS removal efficiencies recovered to the state before back-washing was about 4h and 4-8h,respectively.It is therefore concluded that appropriate back-washing modes of BAF can not only improve the system＇s efficiencies and biofilm＇s activities,but also extend the back-washing cycle of BAF and decrease the operating cost. |
