| 中文摘要 |
| 曝气生物滤池具有体积小、处理效率高、出水水质好、流程简单的优点,最大特点是使用了一种新型粒状填料。它的去除机理主要有过滤、吸附和生物代谢。填料高度对去除效果有很大影响。研究结果表明,去除率同填料高度成正相关,最上层的37cm 厚滤料去除污染物的效果最好,该处的SS、COD、BOD5、NH3-N和T-N的去除率分别为70%、82.5%、66.95%、53.6%和50.2%。 |
| 英文摘要 |
| The Biological Aerated Filter(BAF) has many advantages, such as small volume,high treatment efficiency,good effluent quality and simple process. The biggest characteristic of it is using granular media. The removal mechanism is filtration,absorption and biological efficiency. The height of granular media has an important effect on removal efficiency. The reserch results showed that removal percent is positively interrelated to the height of media. In the upper 37cm, the removal efficiency is very high. The test showed that when the media height is 37cm, the removal efficiency for SS,COD,BOD5,NH3-N and T-N is 70%,82.5%,66.95%,53.6% and 50.2% respectively under the hydrolic rate of 0.53m/h. |
