Аннотация: Every year, the atmosphere in Kazakhstan is polluted approximately 5-7 million tons of pollutants,about a third of which belong to the vehicle. Also excess pollution of the air basin of the cities ofthe Republic is caused by pollution of pollutants by metallurgy, oil refining and chemical industryfactories, automobile and railway transport. The harmful substances emitted by motor transportadversely affect the air, water reservoirs, soil and the planet’s biosphere. At Nowadays car engineconsumes about 3 kilogram of atmospheric oxygen when liters of gasoline per 1 kg are burned.Every car delivers 60 m3of gas per hour, and the truck produces 120 m3of gas. These substancesare very dangerous for living organisms and finding solution for the problem of cleaning exhaustedgases is very actual.The purpose of this article is mathematical and numerical modeling on transfer processes in motor-car neutralizer with usage modern programming language and modern computing technologies.The solution of such a problem brings a certain contribution to the protection of the environmentfrom automobile exhaust gases. The task of cleaning at exhaust gases is investigated, that is tosay catalytic oxidation of exhausted gases automobile neutralizer . The mathematical model thereis a system of differential equations warm and mass transfer including heat generation from thechemical reaction. The equation system is solved through numerical methods and to create anddevelop an algorithm of computing the task of cleaning exhaust gases in automobile neutralizer.

Аннотация: The paper uses the method of economic, environmental and mathematical modeling. The management methods that are most effective in terms of "environmental" and "production" criteria are selected. This selected most effective method of management is not an easy task It is proposed to use the method of economic, environmental and mathematical modeling on a computer to solve it. The results of this simulation can be used in decision-making in the fields of ecology, health, industry medicine, investment planning, urban planning, and other areas of industry.

Аннотация: It is considered that Norilsk ranks second in terms of atmospheric contamination. Industrial enterprises annually emit large amounts of sulphur dioxide, phenols, and heavy metal particles. The city is located within the Far North and is distinguished by the harsh climate of the subarctic type. The snow cover can lie from 244 to 277 days. Snow is a good sorbent; therefore, the snow cover accumulates solid and gaseous pollutants that enter it from the atmosphere with precipitation or are absorbed from it. The purpose of this study was to analyse the snow cover in the Norilsk industrial region and assess the state of atmospheric air in the winter. To achieve this goal, it is necessary to solve the following tasks: conduct a literature review on a given topic; take samples of snow in various industrial districts of Norilsk; study the dependence of the qualitative characteristics of snow on the sampling site; draw conclusions on the quality of snowpack in different areas of the industrial districts of Norilsk. In the course of the study, the following methods were used: organoleptic, visual, methods for determining water transparency, titrimetric analysis, etc. Heavy metal ions and sulphate ions were not detected in the thawed snow, so no industrial gas pollution was noted in the residential area. Most of the particulate contamination was caused by slagging of roads to improve vehicle traction.

Аннотация: The article proposes methods for the extraction of lead and zinc from slag waste and selects the optimal method for the selective extraction of zinc and lead oxides from dust and slags of lead production. The proposed technology of continuous carbon-free selective extraction of zinc and lead from the dust of electric steelmaking production allows the use of lead production slag, which is fed into a rotating drum furnace in two oppositely directed streams. During the movement of lead slag in the furnace drum and the burning of the torch, lead and zinc are more completely extracted from the dust-like material, where the transporting object is compressed air, and the purified flue gas after the gas is further purified by means of a smoke pump is released into the atmosphere.
