| 摘 要： | 在气升式内循环生物反应器的内循环管中，安装蜂窝状陶瓷载体构成一种新型的生物膜反应器，利用该反应器对模拟生活污水进行NH3-N去除的研究。并与相应的活性污泥法进行比较。实验结果表明：生长于蜂窝陶瓷的生物膜，其对废水的硝化性能显著地提高。在脱氮效果和速率上，生物膜法比普通的活性污泥法具有明显的优势。在此基础上探讨了内循环对生物脱氮的机理。

| Abstract: | A kind of ceramic honeycomb support was installed in internal airlift loop reactor to form a biofilm reactor, and it was also used for study on NH3- N removal in simulation municipal wastewater compared with the method of activated sludge. The experimental results show that the nitrification of the wastewater was increased as biofilm on ceramic honeycomb support. Compared with activated sludge, the biofilm has obvious advantage, on based which the NH3 - N removal mechanism of was discussed also. |
