The results of experimental researches of starting of wastewater biological treatment establishment with high contaminants of organic matter, nitrogen are presented. Consecutive anaerobic and aerobic conditions, the fibrous carrier for microorganism’s immobilization in bioreactors are using.

The obtained effects of wastewater treatment on COD – 57,3%, on total nitrogen – 65,3%, on ammonium nitrogen – 70,8% present that it was confirmed effective work of microorganisms-destructors and oxidators of nitrogen.

For microorganism’s adaptation, necessary biocenoses creation and biomass growing on carrier surface in anaerobic and aerobic bioreactors duration of system work must be not less than 22 days. For this condition, the effect on COD is over 90% at initial COD – over 1000 mg/dm3.

Key words: wastewater, biological treatment, bioreactor, anaerobic conditions, aerobic conditions, carrier for microorganisms immobilization.
