Constructive and technological methods of organizing the process
of energy-efficient stabilization of sewage sludge

Abstract. The constructive and technological methods of organizing the process of energy-efficient stabilization of sewage sludge are considered. Intensive anaerobic fermentation with the organization of the process in accordance with the kinetics of fermentation processes and the subsequent use of the fermented mass as an organic fertilizer is proposed as one of the most promising methods of processing and utilization of sediments. In the conditions of mass construction of enterprises for the treatment of urban and industrial wastewater, the most difficult problem is the treatment of precipitation. Large volumes, bacterial contamination, the presence of organic substances that can quickly rot with the release of unpleasant odors, as well as the heterogeneity of the composition and properties of precipitation complicates their processing. The purpose of the study is to select the most effective methods and equipment for processing sewage sludge. The scientific novelty lies in the organization of the process of energy-efficient stabilization of sewage sludge proposed by the authors with the help of an innovative self-washing disc filter.
