Atmospheric Environmental Impact Assessment Study On Cement Kiln Co-disposal Of Garbage

Cement kiln co-processing of living waste has environmentally harmless characteristic and with strong solid waste disposal ability,at the same time use of the existing facilities to carry out the cement kiln collaborative disposal of household garbage,not only can save the construction investment of a new facilities for central treatment of solid waste,but also can alleviate the pressure of the society of solid waste disposal site selection and facilities for central treatment of new covers and other issues.Cement kiln co-processing of living waste have the important siginificance of promoting the transformation and upgrading of green cement industry,industrial resource utilization and improve the level of environmental protection.There are 3 representative technology schemes of using cement kiln co-processing city living garbage of Conch,Huaxin and Sinoma.This study selected CKK system by Conch.This study selected two different parts of the cement kiln of disposal of household garbage project as the research object,and combined with the feature of two area topography and climate,use AEROMOD to forecast the unorganized emissions.The cement kiln of disposal of household garbage project running moment of typical maximum under the condition of grid points before and after the PM₁₀,SO₂,NO₂,concentration of HCl,mercury,lead and cadmium contribution,further analysis of the cement kiln for coordination of living garbage in different regional atmospheric environmental impact characteristics.Through the study shows that affected by terrain,climate differences both typical moment,typical,and long-term weather conditions in A instance of PM₁₀,SO₂,NO₂ is generally higher than the average contribution concentration area as an example,B NO₂ is particularly prominent.B area atmospheric environment quality is poorer,especially during the winter heating season,the main pollutant is PM₁₀and PM_2.5.But cement kiln co-processing of living waste is feasible in B area,the new contribution of pollutants concentration is low.By conducting atmospheric pollution comprehensive integration,the regional environmental quality will improve.
