摘要：One of the most effective methods of wastewater treatment is a biochemical method that almost completely disposes various dissolved organic matter. To improve the oxidation capacity of aerotanks and to control the biochemical processes of wastewater treatment, it was necessary to determine experimentally biocenosis variability influenced by the environment and other factors.The goal of the present research is intensification of biological wastewater treatment by means of direct effect upon the metabolism of activated sludge microorganisms. The experiment studied the organization of species and quantitative composition of active sludge biocenosis in aerotanks while removing contaminants from wastewater. The experiments were carried out in continuous-flow aerotanks of publicly owned treatment facilities. Everyday over a period of three weeks, samples of microorganisms were obtained from aerotanks, quality and quantity objectives of purified water.
