INVESTIGATION AND PRODUCTION OF SORPTION MATERIALS BASED ON RECYCLING TECHNOLOGY OF WASTE OF HEAT AND ENERGY INDUSTRY

Abstract

The main objective, aimed at reducing the environmental impact of waste water from the enterprises of the fuel and energy complex, is the development of recycling water use systems. However, recycled water can often not be used to power steam generators even after purification, since in the best case, un-emulsified petroleum products, iron oxides and cations of dissolved metal salts are removed from the condensate. But, as a rule, these condensates returned from production contain substances that are not completely retained by cationization or sorption, such as emulsified petroleum products, halogenated organic substances. If there is an insignificant sorption of these substances, the capacity of such materials is so small that it is not necessary to take it into account. The discharge of such waters into the drainage will cause only economic losses, since without thorough cleaning and pre-cooling it is prohibited. It is important that the presence of these substances is not detected by conventional chemical and instrumental monitoring at TPPs, since they do not change the pH and electrical conductivity of the solution. Such compounds can cause a negative impact on the work of utilities and heat-power equipment: in steam generators, undergoing hydrolysis, they can act as strong acids, enhance foaming and cause steam pollution, and participate in the formation of scale [1]. Purpose: To obtain and investigate the sorption properties of the feed material from the coal mining waste. Upgrade the standard filtration block system by introducing both new design parameters of the filtration units and the use of filtration loads with high sorption characteristics. Justify from the point of view of environmental and resource conservation of this material. Methodology: standard methods of water quality assessment were used to analyze sorption properties of materials. Methods for thermographic analysis of the composition of the glaze, methods of mathematical modeling and interpretation of the results of the study. Results: sorption material was obtained, optimum sorbent activation regimes, efficiency and selectivity of sorption at various temperatures and pH. Practical implications: The results of this study can be applied in filtration plants of energy companies for the purpose of purifying water from oil products and heavy metals
