Today, in the context of industrial development, an integral part is the formation of wastewater with the need for its subsequent treatment. The biological method of wastewater treatment is the most effective, safe and reliable. This method is based on the work of activated sludge, which is a biocenosis of microorganisms that absorb pollutants from wastewater. Different quantitative and qualitative composition of wastewater and physical impacts can affect the work of the biological agent - activated sludge, therefore research in this area is relevant. To increase the efficiency of biological treatment, a number of methods are used, one of which is ultrasonic exposure of sludge to increase its biochemical activity. However, this approach requires studying its effect on activated sludge microorganisms. In this research work, the effect of ultrasonic exposure on flakes and biocenoses of activated sludge from treatment facilities of various wastewaters was studied and the change in the content of heavy metals after acoustic processing of sludge was determined.
