Anaerobic-aerobic wastewater treatment technology by nitrogen compounds are proposed and investigated. In it provides use of immobilized on a nylon fibrous support of microorganisms and provides a high cleaning effect of ammonium nitrogen – 96-98,6%, the concentration of nitrate and nitrite in the treated water is in accordance with discharge into natural water. As a result produced a small amount of sewage sludge – 0.2-0.4 g/(m3∙d) with high mineral part – 38-48%.

Keywords: microorganisms immobilization, wastewater treatment, nitrogen compounds.
