飘尘的性质、危害和防治对策研究

Characteristics,Harm and Prevention of Airborne Dusts

飘尘污染是大气污染重要的方面,飘尘污染控制问题逐渐引起人们的重视。本文论述了大气漂尘的性质、危害和污染防治对策问题。从人们重视程度,飘尘脱除的技术难度及粉尘的爆炸对飘尘量增加影响等3个方面分析了飘尘污染日益严重的原因;分析了飘尘的性质与环境影响的关系,从重金属成份浓缩性,表面积增大和多孔性,吸附性,润湿性和爆炸性等方面分析了飘尘的环境影响,并在分析飘尘危害的基础上,提出飘尘污染防治措施。提高人们对飘尘污染认识,控制飘尘污染具有重要指导意义。

Dust pollution is an important aspect of air pollution,which has gradually attracted public attention. This paper discusses the nature,harm and pollution control countermeasures of atmospheric drift dust. The importance of public attention,difficulty of dust removal technology and influence of dust explosion are analyzed to study causes for the worsening dust pollution.The paper analyzes the relationship between nature and environment and discussed the impact of dust from the perspectives of heavy metal elements concentration,surface area,porosity,adsorption,wettability and explosive aspects. Dust pollution prevention measures is proposed based on the analysis of dust hazard,tying to raise awareness for dust pollution and providing reference for dust pollution control.
