| Abstract: | An up-flow anaerobic sludge blanket reactor was operated in order to investigate the effects of salinity(sodium chloride formulations, ranging from 0 to 33 g · L-1)on nitrogen removal via the Anammox process. The reactor had been run for 106 days under no salinity-stress condition before this experiment. The results showed that the appropriate salinity for the Anammox bacteria to be acclimatized was about 2.5 g · L-1.The nitrogen removal efficiency increased steadily at salinities below 30 g · L-1 and the total nitrogen removal efficiency was over 75%. The nitrogen removal efficiency was significantly inhibited as the salinity increased over 30 g · L-1(p<0.05). However this kind of inhibition was reversible. The ratio of NH4+-N (removal rate) and NO2--N (removal rate) to NO3--N (product rate) matched the theoretical values of the Anammox process over the whole experiment period, revealing that Anammox nitrogen removal theory is suitable for application to high salinity synthetic wastewater. |
