The article is devoted to the unsatisfactory operation of biological wastewater treatment plants. At present in Ukraine there are no developments of equipment and devices to ensure the operation of treatment facilities using the technology of nitridenitrification of deep wastewater treatment from nitrogen and phosphorus compounds. The analysis of the equipment of biological treatment systems - nitri treatment plant - denitrifier, clarifier tanks is carried out. At the same time, the standards of the degree of purification of both Ukraine and the European Union were taken into account. On the example of treatment facilities in Kolomyia, Ivano-Frankovsk region, modern schemes of biological wastewater treatment for the removal of nitrogen and phosphorus have been proposed, namely, the re-equipment of single-corridor aerotanks into bioreactors of nitridenitrifiers by creating zones with different oxygen conditions in their volume.
