Abstract

Three kinds of seeding sludge, i,e, conventional activated sludge, anaerobic granular
sludge and the nitrifying activated sludge from the nitritation reactor treating aged
leachates were evaluated in batch mode to screen the optimized inoculum for the rapid
start-up of ANAMMOX reactor. The feasibility of the ANAMMOX process for the
treatment of aged leachates was also investigated in a modified upflow anaerobic sludge
blanket (UASB, 0,05 m\ The batch experiments revealed that the nitrifying activated
sludge from the nitritation reactor could respectively achieve the NRR (nitrogen
removal rate) of 0,0365 kg N/(m3
,d) and the ARR (ammonium removal rate) of 0,013
kg N/(m3
.d) on day 12, which were greatly higher than those of the other two tested
sludge samples, The mixture of the aforementioned nitrifying activated sludge and
anaerobic granular sludge was established as an effective inoculum for the prompt startup of ANAMMOX reactor. The maximum total nitrogen removal rate of 0,826 kg
N/(m3
,d) could be obtained for the treatment of "old" leachates under NLR (nitrogen
loading rate) of 1.028 kg N/(m3
.d), It is concluded that the N-removal performance of
ANAMMOX process is still to be improved for actual engineering application to aged
landfill leachates,
