摘　　要：Simultaneous removal of sulfide, nitrate and ammonium salts was achieved in an upflow anaerobic sludge blanked(UASB) reactor by the start-up strategy of gradually decreasing influent nitrite to null. The sulfide/nitrate-nitrogen ratio could affect the distribution of end products of sulfur, and a sulfide/nitrate-nitrogen ratio of 1:0.76 is proposed as optimum for S^0 accumulation. The Denittrasoma, Thiobacillus, and Candidatus_Kuenenia presented the functional strains in the studied reactor. This result can provide a theoretical and technical basis for the large-scale application of anaerobic ammonium oxidation process.Simultaneous removal of sulfide, nitrate and ammonium salts was achieved in an upflow anaerobic sludge blanked(UASB) reactor by the start-up strategy of gradually decreasing influent nitrite to null.
