Abstract
The technology of biological treatment of industrial and urban wastewater, based on the alternation of anaerobic and aerobic stages, taking into account the modernization and re-equipment of existing treatment facilities, is considered. It was shown that the use of disk aerators of a new type makes it possible to achieve a high degree of wastewater treatment from phosphorus compounds. The duration of anaerobic and aerobic stages was experimentally estimated. The tasks of hydrodynamic and mass transfer studies of the bio-purification process were formulated in order to create engineering methods for calculating industrial processes.
