چکیده انگلیسی
A lab-scale anammox up-flow anaerobic sludge blanket (UASB) reactor was run to investigate the influence of temperature on anammox performance and community structure. The anammox system had a higher substrate tolerance at 13â¯Â°C than at 18â¯Â°C. The adverse effects caused by the use of a lower temperature (8â¯Â°C) could be restored. The nitrogen removal rate (NRR) decreased with decreasing in situ specific anammox activity (SAA). Interestingly, the ex situ SAA acclimated at 23â¯Â°C, when exposed to ex situ temperatures of 33 and 28â¯Â°C, was higher than for those acclimated at 33 and 28â¯Â°C. No shift was observed in the optimum temperature for ex situ SAA in the whole lowering process of anammox UASB. More extracellular polymeric substances were produced in response to cooler conditions (18â¯Â°C and 13â¯Â°C). Ca. Kuenenia became much more abundant (55.18% of the microbial community) and had a competitive advantage over other anammox bacteria (AnAOB) at 13â¯Â°C.
