Abstract:The influences of BMTM biofilm carriers on starting-up of the anaerobic ammonium oxidation (Anammox) process were investigated using two reactors, named R1 and R2 respectively. R1 was an UASB reactor, after 140 days’ starting-up, the removal efficiency of ammonium and nitrite only increased to 54.6% and 58.8%, with the sum of ammonium and nitrite removal loading rates of 0.09 kg/(m3·d). Then 0.6L BMTM biofilm carriers were added into R1, and in 26 days, the ammonium and nitrite removal efficiency increased to 92.5% and 97.4%. R2 was an upflow packed-bed reactor, in which the same quantity of seed sludge and BMTM biofilm carrier as that of R1 were added, after 83 days’ strating-up, the removal efficiency of ammonium and nitrite increased to 83.6% and 89.4% respectively, and the sum of ammonium and nitrite removal loading rate was 0.22kg/(m3.d), suggesting a much faster and better starting-up in R2 compared with R1.
