Description
Technical field
The present invention relates to technical field of air purification, refer in particular to a kind of reduction Atmospheric particulates (PM
2.5) method of concentration, specifically, refer to a kind ofly reduce Air Pollutant Discharge PM using the sodium chloride aerosol of particle diameter 0.1 ~ 10 μm as adsorbent
2.5the method of concentration.
Background technology
Atmospheric particulates (particulatematter, PM) be one of air pollutants main in air, also be the major pollutants at present China's most cities air quality impacted, and wherein aerodynamic diameter in Atmospheric particulates is less than or equal to the fine particle (ineparticulatematter) of 2.5 μm by us, be called PM2.5, it easily causes haze weather to cause On The Deterioration of Visibility Over, and it carries a large amount of poisonous and harmful substance, harmful effect can be caused to health, simultaneously, there are some researches show in air the trace contaminant entered by breathing in human body, potential hazard than the water drunk containing equivalent pollutant and food larger, therefore, effective reduction air PM
2.5concentration is most important to health.
The invention provides a kind of reduce atmosphere particle concentration method, the method is simple, green, effectively makes PM in air
2.5concentration is reduced to 10ug/m
3below, improve Mass Control, maintain health, be specially adapted to place air in clean room.
Summary of the invention
