Estimation of the technical and economic expediency of biological wastewater treatment facilities for oil extraction enterprises using a biocenosis of aerobic thermophilic microorganisms

Summary

A process flow scheme was developed for the biological treatment of wastewater of oil extraction production enterprises using aerobic thermophilic microorganisms immobilized on inert media. Based on the constants of the equations of enzymatic kinetics of biological wastewater treatment obtained during the experimental studies, a methodology for calculating the facilities was adapted, and formulas were substantiated to calculate the residence time in aeration facilities providing for a set treatment level. A technical and economic analysis showed the feasibility of using the proposed biological treatment method in bioreactors with a biocenosis of aerobic thermophilic microorganisms immobilized on a biological media block. Based on the calculation of the life cycle cost, the economic feasibility of the developed technology for the treatment of wastewater from oil extraction production was proven; the prime cost was 25.68 rubles/m3.
