Features of qualitative and quantitative composition of emissions in the production of building materials
Incoming article date: 10.11.2016The article is devoted to the peculiarities of qualitative and quantitative composition of emissions in the production of building materials. This article describes a way of reducing dust emissions of solid substances pollutions exhausted in the atmosphere in the manufacture construction materials. The article focuses on the environmental problems of building construction industry. Volume of production of building materials is growing up and amount of dust particles substances in emissions around 5-8% every year at least both. One of ways to increase the environmental safety is reduction of dust emissions. Data on the relative content of some types of dust, typical for the construction industry in the total dust emissions entering the atmosphere of the city enterprises. The results of studies show that a significant content of fine particles, for example, 10 microns or less is concern in dust emissions systems of aspiration at the building construction enterprises. The great amount mention above of solid substances fine particles dimension involves the usage of special complex integrated analysis method of variance dust. The great amount mention above of solid substances fine particles dimension involves the usage of special complex integrated analysis method of variance dust. The value of the maximum permissible concentration of fine particles content by mention above dimension (around 10 microns) is less than for ordinary powder of building materials’ dusts. There exist and work a lot of building materials enterprises treat with bulk building materials in present time. It isn’t necessary to have ecological project of limitation emissions for small construction companies. So that this reason demands the improvement norms methodology for limitation for fine particles are concern in dust emissions systems of aspiration at the building construction industry. It allows preventing growing pollutions of atmosphere by emissions with fine particles dust.
