| 摘要: |
| 当水力停留时间（HRT）为8 h时，以陶粒填料曝气生物滤池（BAF）（简写为HBAF-PC）为对照组，考察了陶粒/竹丝复合填料BAF（简写为HBAF-FBPC）对氮素污染物转化效果及生物特性。结果表明，HBAF-FBPC和HBAF-PC对TN去除率分别为70.2%~95.7%和32.5%~67.1%，HBAF-PC出水NO3--N质量浓度介于15.2~48.8 mg/L之间，而HBAF-FBPC出水NO3--N质量浓度稳定低于14.5 mg/L；相对于HBAF-PC而言，HBAF-FBPC具有更低的NO2--N积累质量浓度。而且因为竹丝的存在，HBAF-FBPC中具有更快的美人蕉生长速率、更高质量浓度的内含物和更丰富的指示性微生物。复合滤料BAF处理生活污水是可行的。 |

| Abstract: |
| The improved efficacy of hybrid BAF with filamentous bamboo and palygorskiteceramistite (HBAF-FBPC) in removing nitrogen from wastewater was compared with the hybrid biological aerating filter with palygorskiteceramistite (HBAF-PC). The experiment was conducted under continuous flow condition and the average hydraulic retention time was eight hours. The results showed thatthe removal rate of total nitrogen by HBAF-FBPC and HBAF-PC was 70.2%～95.7% and 32.5%～67.1%, respectively. The effluent nitrateconcentration from the HBAF-PC and HBAF-FBPC was 15.2～48.8 mg/L and 14.5 mg/L respectively, and compared with HBAF-PC, HBAF-FBPC was more efficient in removing nitrite. In addition, the HBAF-FBPC boosted the growth of Canna and microorganisms due to its filamentous bamboo. |
