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NO_3~--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NO_2~--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。

摘 要：
The improved efficacy of hybrid BAF with filamentous bamboo and palygorskiteceramistite(HBAFFBPC) 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.
