| 中文摘要 |
| 将城市生活污水处理厂活性污泥中的反硝化细菌培养挂膜到填料塔中,进行从模拟废气中脱除NOx的效果性能实验研究。该生物膜填料塔能有效地脱除废气中的NOx,NO2的去除率可达99%以上,NO的去除率可达90%左右。该法最适宜的温度为30～45℃,进口NO浓度(50～500mg/m3)对其去除率几乎没有影响,随着废气流量的增加,NO的去除率逐步降低。 |
| 英文摘要 |
| A biological column with denitrifying bacteria from activated sludge in urban domestic sewage treatment plant was set up to study removal of NOx from waste gas.It was shown that biological column can be used to reduce NOx to the elemental nitrogen.The NO2 removal efficiency was more than 99% and the NO removal efficiency was about 90%.The optimum temperature of denitrifying bacteria was 30℃～45℃.The initial NO concentration(50mg/m3～500mg/m3)had little effect on the removal efficiency.The NO removal efficiency was decreasing with increasing flow of waste gas. |
