In this study, a novel acryl fiber biomass carrier (ABC) was applied for anammoxresearch in an up-flow column reactor. This material could retain anammox microorganismefficiently and the average weight of attached sludge in the bottom part of the reactor wascalculated to be 0.14 g-TSS/cm3 ABC. High removal efficiencies of ammonium, nitrite andTN were obtained at a high volumetric loading rate of 2.0 kg-TN/m3/d. Furthermore,anammox activity did not decrease significantly with decreasing temperature, e.g., whenthe temperature decreased from 33.0℃ to 26.2℃, nitrite removal efficiencies decreasedonly about 5% (from 94% to 89%). Scanning electronic microphotographs revealed thatthe microorganisms were in a compacted state when attached on the support material.Based on the analysis of 16S rDNA, two close matches of anammox bacteria, KSU-1 andKOLL2a, were detected. This material showed potential for treatment of wastewater withlow concentrations of nitrogen using a short hydraulic retention time.
