METHOD FOR DETERMINING CONCENTRATION OF SUBSTANCES IN BIOLOGICAL WASTEWATER TREATMENT SYSTEM Russian patent published in 2021 - IPC C02F3/02 

FIELD: water treatment.

SUBSTANCE: method relates to the field of water discharge and to methods for modeling apparatuses (devices) for biological wastewater treatment at sewage treatment facilities. The biological treatment system is comprised of mixing chambers, aeration tanks, settling tanks. An aeration tank is divided into areas for anaerobic treatment and oxide treatment. Said areas are divided into sub-elements. The concentration of contaminants in the treated wastewater and the concentration of substances in the biological wastewater treatment system are determined in streams considering the processes occurring in the apparatuses (devices) inside each element. The output stream of the sub-element is therein the input stream of the subsequent sub-element of the system.

EFFECT: expanded range of application of the method for wastewater treatment, improved quality and reliability of biological wastewater treatment.
