| The research object of the report is to determine the pollution from the selected steel enterprises by means of studying natural and social environment, pollution sources and other pollution factors, acquiring the weather condition of typical day by condensing data from wind velocity, wind direction, atmospheric stability and comprehensive frequency; calculating the influential factors of typical day of iron and steel works through mathematical model-Gauss point source diffusion principle. The aim of the article is to provide theory with practice data for generation technology by blast furnace gas combustion and for energy conservation and emission reduction to meet the regulation of the national standard on environmental protection and for further environmental benefit. According the comparative data between before and after pollutant harnessing, we can reach a conclusion that the waste heat power station has remarkable environmental benefits, economical benefits and social benefits. Meanwhile, this method of pollutant harnessing would certainly provide a new effective model of thinking, but also a new effective and practical measure for environmental protection. |
