Wpływ bioaugmentacji osadu czynnego wyselekcjonowanymi szczepami bakterii oraz ich konsorcjum na efektywność procesu oczyszczania zafenolowanych odcieków ze stawu Kalina

Abstract

The main purpose of this study was to assess the effluent treatment efficiency after bioaugmentation of the activated sludge spiked with the landfill leachate from the bottom sediments of the Kalina pond in Świętochłowice with P. putida OR45a and P. putida KB3 strains, as well as their consortium. Moreover, the impact of introduced bacteria on the activated sludge condition, enzymatic activity, content of live biomass and the functional potential of the autochthonous microbial communities present in this environment was evaluated. Analysis of the operational parameters and indicators of the activated sludge condition and functional potential of indigenous microorganisms showed a strong correlation between the application of bioaugmentation strategy in the bioreactors loaded with the leachate from the Kalina pond and high microbiological activity and efficiency of the wastewater treatment process. Inoculation of the activated sludge with P. putida KB3 strain proved to be the most effective solution among the bioaugmentation strategies that have been used. Due to the high bioaugmentation potential, introduction of/1- putida KB3 strain into activated sludge can be an effective solution to the problems of many wastewater treatment plants loaded with phenolic landfill leachate.
