Theoretical Substantiation of Wastewater Treatment Schemes Using Airlift Bioreactors
Abstract: The article describes the theoretical models of schemes for improved biological phosphorus removal, created on the basis of the Johannesburg and Cape Town processes, modified by the use of aerotanks-clarifiers with a flooded airlift aeration system (airlift bioreactors). The application of modeling of biochemical processes using ASM3 + Bio-P is proposed, which allows describing the mutual transformation of the components of the activated sludge system and predicting the quality of treatment in such facilities. For modeling airlift bioreactors, dependencies are proposed for determining the circulation flow in the facility. Modeling was carried out according to the indicated dependencies for the initial wastewater of the city of Makeevka, with the development of measures to improve the quality of treatment by varying the parameters of the facilities and adding an organic substrate. A theoretical assessment of the effectiveness of the proposed schemes, limitations of their application is carried out. It has been established that the most significant parameter for the final quality of treatment is the ratio of organic matter, nitrogen and phosphorus in the initial runoff.
Keywords: biological treatment, gas-loop bioreactor, simulation of activated sludge biochemical processes.
