ANALYSIS OF POLLUTANTS EMISSIONS INTO THE ATMOSPHERE BY STATIONARY SOURCES
Keywords:forecast estimation, sulfur dioxide, nitrogen oxide; concentration, toxicity index.
Ivano-Frankivsk region was taken to estimate the emission of harmful substances into the air, since this region has a considerable amount of recreational resources.
Waste generation of electricity at thermal power plants complicate the ecological situation in the country. Solving the problems associated with environmental protection and improving the quality of its social component is becoming more relevant. The urgency is to reduce the technogenic load on the environment by heat generating companies.
The purpose of the work is to analyze and forecast the emission of pollutants into the air by stationary sources. In the process of research, the issues were solved analysis of ground concentrations of pollutants on the border of the sanitary protection zone and forecasted estimate of future emissions.
The change of emissions of pollutants for a certain period of time is analyzed. For the analysis of the existing emissions of Burshtinskaya TPP and their comparison with the MAC, the ground concentrations of pollutants at the boundary of the sanitary-protective zone are calculated. Burshtyn TPP falls into the second category of danger. The projected estimate of future emissions is constructed and measures are taken to minimize them. The toxicity index has been calculated taking into account weight coefficients. The analysis of emissions indicates excessive MAC for some pollutants. According to the toxicity index, which takes into account both the hazard class of substance and the degree of exceeding the MPC, measures are recommended for the reduction of emissions of certain substances and the choice of fuel with a lower content.
It is recommended to choose a fuel with a lower content in emissions not only of substances such as nitrogen oxide, suspended solids, sulfur dioxide, but also lead and its compounds. When installing and reconstructing flue gas cleaning systems for Burshtinskaya TPP, it is necessary to take into account the filtration capacity of equipment for substances with a high toxicity index.
To unify the calculations, analysis in the context of the selected time period, the possibility of application for other objects of management software was developed.
