The main sources of highly concentrated multicomponent technological solutions at thermal power plants (TPPs) are water treatment plants. Analysis of operation of the ion-exchange water treatment plant at the Nizhnekamsk Thermal Power Plant-1 showed that half of alkali supplied to regeneration of the anion-exchange alkali filters is not used, but is discharged for neutralization and then to wastewater. Due to the fact that the cost of alkali used in technological processes is quite high, it is economically feasible to process the alkaline waste with the alkali extraction and its reuse in the production cycle. The article presents the experimental results on the electro-membrane separation of alkaline waste regeneration solutions and wash water after anion-exchange filter regeneration. The revealed differences in the selectivity of various ion transfer through the electrodialysis apparatus membranes, depending on time and amount of transmitted electricity, allowed us to establish the possibility of obtaining an alkaline solution purified from impurities.

АnnotationTechnological installation of waste water disposalafter washing of H-cation filters is quite promising idea of avoiding penalties and reuse of waste water in cycle of thermal power plants (TPP). The development of this unit is based on reactions that occur when mixing several TPP water treatment plant wastes, namely, neutralization and exchange-type reactions. As neutralizing reagent, the sludge of the water treatment plant is used, which consists of CaCO3 by 80%. This method reduces the concentration of sul-phate-containing components in wastewater to a standard level, and also provides neutral wastewater with-out the use of additional purchase reagents.

The article presents model complex for assessing the economic consequences of reducing greenhouse gas emissions in the power system of region. The trajectories of emissions and macroeconomic indicators for the Russian Far East are estimated in the context of maintaining the current parameters of the power system efficiency and in the context of power system transformation (modernization of thermal power plants, transition of thermal power plants from coal to gas with the development of gas processing industry). The results of calculations confirm that an emissions reduction is a secondary effect for selected transformations of the region’s power system
