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 av-erage 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 nitrateconcentra-tion 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.
