| 520 | 3 | |a This paper investigates a novel sulfur-oxidizing autotrophic denitrifying anaerobic fluidized bed membrane bioreactor (AnFB-MBR) that has the potential to overcome the limitations of conventional sulfur-oxidizing autotrophic denitrification systems. The AnFB-MBR produced consistent high-quality product water when fed by a synthetic groundwater with NO3 −-N ranging 25-80mg/L and operated at hydraulic retention times of 0.5-5.0h. A nitrate removal rate of up to 4.0g NO3 −-N/Lreactord was attained by the bioreactor, which exceeded any reported removal capacity. The flux of AnFB-MBR was maintained in the range of 1.5-15Lm−2h−1. Successful membrane cleaning was practiced with cleaning cycles of 35-81days, which had no obvious effect on the AnFB-MBR performance. The 15 N-tracer analyses elucidated that nitrogen was converted into 15 N2-N and 15 N-biomass accounting for 88.1-93.1% and 6.4-11.6% of the total nitrogen produced, respectively. Only 0.3-0.5% of removed nitrogen was in form of 15N2O-N in sulfur-oxidizing autotrophic denitrification process, reducing potential risks of a significant amount of N2O emissions. The sulfur-oxidizing autotrophic denitrifying bacterial consortium was composed mainly of bacteria from Proteobacteria, Chlorobi, and Chloroflexi phyla, with genera Thiobacillus, Sulfurimonas, and Ignavibacteriales dominating the consortium. The pyrosequencing assays also suggested that the stable microbial communities corresponded to the elevated performance of the AnFB-MBR. Overall, this research described relatively high nitrate removal, acceptable flux, indicating future potential for the technology in practice. | |
