This article discusses aerobic stabilization of sludge in sewage treatment plants. Particular attention is paid to the sedimentation rate and the quality of sludge dewatering of primary and secondary sedimentation tanks. Tables and graphs of the results of experimental work on the change in the ability of sediment to rot, change in the rate of oxygen consumption by activated sludge in the process of aerobic stabilization of the mixture of sediments, the dependence of the specific resistance of filtration on the duration of aerobic stabilization for sediments of various aeration stations in the region are presented. Mathematical analysis and calculations of the duration of aerobic stabilization are carried out according to the method developed by the Bukhara Engineering and Technological Institute. At the end of the work, conclusions and recommendations for the application of this method are given.
