Abstract

In this work was used activated sludge from the WWTP (wastewater treatment plant), in which with technique accumulation nitrificants and denitrificants, were prepared mixed bacterial cultures which showed the ability nitrification of ammonia- nitrogen to nitrate, as well as the ability of denitrification of nitrate nitrogen to gaseous nitrogen in municipal wastewater. As carbon source in the process of biological denitrification was used sodium acetate, in the ratio C/N=1 and C/N=2. Activity of mixed microbial cultures for removal components with nitrogen was determined by measuring the concentration of organic matter, expressed as COD, ammonia-nitrogen, nitrite, nitrate, pH, concentration dissolved oxygen, and the concentration of microbial biomass. Keywords: municipal water, activated sludge, nitrogen removal
