BIO-TREATMENT OF INDUSTRIAL AND URBAN WASTEWATER FROM PHOSPHORUS COMPOUNDS

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.
