Development of technology for bio-induced activation of active sludge microorganisms by krebs cycle metabolites in aerotanks of wastewater treatment plant in the city of Sumy

Under modern conditions, the traditional biological treatment technologies existing at most wastewater treatment plants in Ukraine do not allow for achieving stable operation of the facilities. The influx of toxic wastewater results in a significant disruption of the functional state of the activated sludge, leading to a deterioration in the biological treatment of wastewater. An effective technology for the intensification of biological wastewater treatment from various types of pollutants is proposed. The method of bio-induced activation of activated sludge microorganisms includes the collection of return activated sludge with its subsequent treatment by Krebs cycle metabolites and continuous aeration for 18–24 hours, followed by feeding with clarified wastewater and the introduction of the treated activated sludge into the aeration tanks. The method of biological activation of activated sludge microorganisms by Krebs cycle metabolites is capable of exerting a comprehensive effect on the biological wastewater treatment processes and achieving stability in the functioning of the activated sludge biocenosis.
