Abstract
Based on the analysis results of the ash material composition obtained from the combustion of domestic sewage sludge, it was found that such sludge belongs to the group of fusible alumina silicate raw materials and can be used as a charge component in the production of building ceramics. A comparative analysis of the characteristics of the ash of the ash of the ash of the ash of the thermal power plant and loam showed that, in terms of the coefficient of philosity and the true density, the ash of the ash of the ash of the thermal power plant differs significantly from the ashes of the thermal power plant. At the same time, in terms of oxide composition and melting point, the ash of SBSW is much closer to loam than to ash from thermal power plants, which indicates its greater chemical affinity with clay raw materials, based on their colloidal chemical origin. By means of an environmental and hygienic assessment, the indicator of the degree of danger of ash BSV (K = 62.47) corresponding to the IV hazard class (10 < K < 102) was determined, which allows it to be used as a raw material in the production of building ceramic materials in the presence of a waste certificate. At the same time, the results of a comparative assessment show that the technology for the production of bricks using ash from the combustion of WWTP does not lead to deterioration in the environmental situation compared to the existing technology for the production of ceramics using ashes from a thermal power plant.
