The article considers the results of a study aimed at establishing the constants of enzymatic kinetics of biological treatment of domestic wastewater in low-oxygen bioreactors of the circulating type and proposes methods for calculating such structures using the dependences of enzymatic kinetics Michaelis-Menten. The technological mode of operation of the reactor implies a total oxygen regime of not more than 1.1 mg / l at horizontal flow rates of 0.25-0.3 m/s. The efficiency of wastewater treatment is achieved by increasing the mass transfer of oxygen to the sludge mixture and directly into the flocs of activated sludge, as well as due to aerobic granulation by built-in secondary settling tanks.

The article discusses the features of granular formation of activated sludge, operating according to the modified DEAMOX technology with nitrification, incomplete denitrification and anammox. Reverse denitrification and anammox are implemented in the same volume of the bioreactor under anoxic-anaerobic conditions with a vertical flow of the sludge mixture. Anammox biomass mainly developed on stationary feed material, while the heterotrophic denitrifying activated sludge showed the ability to granulate up to 20 mm nominal diameter. The article discusses the effect of various temperature conditions on the size and stability of granules.

The article presents the results of a study of activated sludge, which purifies domestic wastewater from nitrogen compounds under conditions of low concentrations of dissolved oxygen in the bioreactor (concentration at the level of 0.2-0.7 mg / dm3). The studies were carried out in laboratory and semi-production conditions on the models of circulating aeration facilities. Research methods included optical, electron and fluorescence microscopy, laser diffraction method and real-time polymerase chain reaction method. As a result of research, the composition and condition of the main indicator microorganisms of activated sludge, the structure of floccules of activated sludge, including the distribution of sizes of floccules depending on various technological conditions of the process, the cause of filamentous swelling of activated sludge in cases of disturbance of the system’s stability, as well as the number of functional bacteria genes archaea associated with the processes of nitrification and denitrification. Separately, research was carried out on the sedimentation properties of activated sludge, which includes the determination of sedimentation rates of activated sludge under the conditions of the mutual influence of floccules and biofloculation potential. Studies were performed both for experimental activated sludge, working with simultaneous nitrification and denitrification with low concentrations of dissolved oxygen, and for the control nitrifying activated sludge, taken from existing treatment plants operating according to the traditional technological scheme of denitrienitrification.
