    Abstract:

    We studied simultaneous removal of sulfide and nitrite by an anaerobic process in an upflow anaerobic sludge blanket (UASB) reactor. The process could remove sulfide and nitrite 13.4 kg/(m3·d) and 2.3 kg/(m3·d), respectively, of the reactor tolerated high influent substrate concentration (880.0 mg S/L and 252.7 mg N/L) with the optimum substrate concentration (460.0 mg S/L and 132.3 mg N/L). It tolerated short hydraulic retention time (HRT) with the optimum HRT of 4 h. The apparent half inhibition concentrations of sulfide and nitrite were 403.9 mg S/L and 120.8 mg N/L, respectively, under different influent substrate concentrations. The combined effect between sulfide and nitrite was antagonistic effect.
