英文摘要: Abstract(#br)Simultaneous partial nitrification, anammox and denitrification (SNAD) process was started-up in a 2.5L sequencing batch biofilm reactor (SBBR) using novel biomass carriers. The SNAD process took only 51d for start-up at nitrogen loading rate (NLR) and organic loading rate (OLR) of 120 and 60g/m 3 -d, respectively. Long-term stable operation of SNAD process was observed at NLR and OLR of 360 and 180g/m 3 -d with average total nitrogen and COD removal efficiencies of >88% and >90%, respectively. The values of conversion ratio Y ( NO 2 - + NO 3 - ) / NH 4 + remained below 0.11 after the start-up period, which further confirmed the long-term stability of SNAD process. Results of polymerase chain reaction...
