摘要
介绍了采用SBR工艺处理济南地区城市污水的最佳运行工况,即瞬时进水,曝气时间控制在3h左右,厌氧时间控制在1h左右,沉淀1h左右。当实验在最佳工况下运行时能有效的去除有机物,并可以达到脱氮除磷的目的。此时,污水的COD、TP、TN的去除率分别能达到80%、75%、30%以上。
The best treatment of Jinan's municipal wastewater by SBR is introduced. That is, the duration of aeration, the anaerobic time and precipitated time is limited to about 3 h, 1 h and 1 h respectively. When this treatment is operated, the effect of removing organic matter as well as nitrogen and phosphorus can be achieved. Here, the removal efficiency of COD, TP and TN of sewage can reach above 80%, 75% and 30% respectively.
