摘要

给出了铝渣处理工艺对大气环境状态影响的数据。对大气表层污染物(PO)的分布进行了计算,一氧化碳、二恶英、二氧化硫、氯化氢和粉尘没有超过最大允许浓度(MPC)。对设备运行的极端条件进行了排放分析。确定在该工艺条件下,污染物的最大浓度为:NO2≤0.2 MPC,其余污染物不超过- 0.05 MPC。为了确定卫生保护区边界有害物质的实际浓度,在距离排放源300米的地方进行了实验室测试。经确定,在符合运行卫生和技术要求的情况下,从企业境内和计算卫生保护区边界的工业场地向大气排放的污染物小于人口居住区大气的MPC,不会对环境产生重大的有害影响。空气中有害杂质含量水平不超过卫生防护区外针对人口稠密地区大气空气制定的卫生标准。关键词:生态,污染物,最大允许浓度,铝渣。

Environmental aspects of foundry aluminum slag processing
Data on the influence of the aluminum slag processing process on the state of the atmospheric environment are presented. Calculations of the dispersion of pollutants (PO) in the surface layer of atmospheric air were carried out, which showed the absence of exceeding the maximum permissible concentrations (MPC) for carbon monoxide, nitrogen dioxin, sulfur dioxide, hydrogen chloride and dust. Analysis of emissions was carried out for extreme conditions of equipment operation. It was established that under such technological conditions, the maximum concentration of pollutants is: NO2 ≤ values of 0.2 MPC, and the rest of the pollutants do not exceed - 0.05 MPC. To identify the actual concentrations of hazardous substances at the border of the sanitary protection zone (SZZ), laboratory tests were performed at a distance of 300 m from the emission source. It was established that emissions of pollutants into the atmosphere from the industrial site on the territory of the enterprise and on the border of the calculated sanitary protection zone are less than the MPC of the atmospheric air of populated areas and will not have a significant harmful effect on the environment, provided that the sanitary and technological requirements for operation are met. The level of the content of harmful impurities in the air does not exceed the hygienic standards outside the sanitary protection zone, which are established for the atmospheric air of populated areas. Keywords: ecology, pollutants, maximum permissible concentration, aluminum slag.
