[Experimental study of autotrophic denitrification bacteria through bioaugmentation of activated sludge from municipal wastewater plant].

Activated sludge of municipal wastewater treatment plant was domesticated by sulfur as the electron donor under autotrophic. The sludge activity was determined by measuring growth rate of sludge. The removal efficiency of nitrate and sulfate production efficiency were analyzed by continuously measuring the concentration of NO3(-)-N and SO4(2-).
