Wastewater conditioning of the hydraulic extraction system using cavitation technology as a basis for reducing the environmental risks of thermal power plants

The results of a study on the use of non-reagent methods for purifying clarified water in closed hydrosol removal systems (hereinafter referred to as GMS) of thermal power plants are presented. Based on theoretical analysis and experimental studies, installations using cavitation technology have been proposed that simultaneously solve the problems of physico-chemical water purification and eliminate the deposition of insoluble salts in pipelines. The purpose of the research is to develop technological proposals and technical solutions for the modernization of classical settling ponds aimed at improving the efficiency of wastewater treatment. The efficiency of purification of clarified wastewater from thermal power plants in standard hydraulic structures - settling ponds does not meet the requirements for the quality of water purification established by Russian environmental legislation both for discharge into natural reservoirs and for the formation of a full-fledged recycled industrial water use. In this regard, it is advisable to develop and introduce into production alternative, non-reactive, and highly effective methods of treatment of multicomponent wastewater. Such methods include wastewater treatment based on the effects of hydrothermodynamic cavitation.
