When using water for the technical needs of industrial enterprises, it needs to be purified to regulatory standards of maximum permissible concentrations, which is energy- and resource-intensive. To effectively purify industrial wastewater from various pollutants, waste from various industries is increasingly being used, which show a high degree of wastewater purification and are inexpensive. In the article, carbonate sludge is used as an adsorbent - a large-tonnage waste from chemical water treatment shops of thermal power plants. This paper presents the results of a study of the characteristics of the sorption material – granular modified carbonate sludge (GrMKSh). Data on the effectiveness of using the sorption material GrMKSh for treating wastewater from phenols is presented: the output adsorption curve under dynamic conditions is obtained, the efficiency of wastewater treatment from phenols is calculated, which is 99.2%. The results of biotesting of an aqueous extract of GrMKSh saturated with phenols on fish of the species Poesilia reticulata Pet. and crustacean Daphnia magna Str. It has been shown that purified water does not have an acute toxic effect on test objects.
