| 摘 要： | 在传统活性污泥工艺中投加聚氯乙烯短管填料,研究投加短管填料对活性污泥工艺性能的影响,将该系统应用于城市污水处理试验研究,并与单一活性污泥系统进行对比研究。结果表明,投加短管填料可以改善活性污泥工艺性能,系统对有机物及氮、磷去除效果显著,可在同一反应器内实现脱氮除磷。与活性污泥系统相比,投加短管填料反应器具有较强的抗冲击负荷能力。 |
| 关 键 词： | 活性污泥 生物膜 短管填料 脱氮除磷 |

| Abstract: | The influence of the use of PVC stub tube fillers in traditional activated sludge reactors on reactor efficiency was studied. The results of the application of the technique in urban wastewater treatment show that stub tube fillers can improve the efficiency of the activated sludge reactor： the organic matter, nitrogen and phosphorus were remarkably decreased and the reactor itself was able to remove both nitrogen and phosphorus. Compared with traditional activated sludge reactors, reactors with stub tube fillers are more efficient under different pollution loads. |
| Keywords: | activated sludge biofilm stub tube fillers nitrogen and phosphorus removal |
