Popis: The purpose of the research was to determine the optimal parameters of air the regeneration of the floating loading that are necessary and sufficient for its high efficiency. Finding similar indicators on an industrial aerotank is very difficult and costly. The model biotank and the experimental setup allow varying in a wide range the intensity of the airy medium-bubble regeneration of the floating loading, the regeneration time, the specific mass of loading, and control the concentration of free floating sludge. To study the kinetics of sedimentation of sludge on the loading, original techniques based on the laws of physical chemistry have been developed and used. An express method for determining the concentration of free floating sludge has been developed and applied. For the first time, the dependences of the efficiency of medium-bubble air regeneration of immobilized sludge on a floating bio-loading of the “Biremax” type on the time and intensity of regeneration, as well as on the specific mass of the loading, were obtained. It is shown that the optimal parameters the air of regeneration of a floating loading energy-saving and necessary for its high efficiency, make it possible to ensure the presence of an immobilized biocenosis, which is necessary for deep wastewater treatment.
