摘要
干散货港区扬尘中PM2.5等大气污染物的分布规律是港口开展抑尘工作的关键依据。以连云港港干散货港区为研究对象,构建无人机搭载微型空气质量检测器的监测平台,从垂直分布和水平分布两个维度研究PM 2.5的空间分布特征。结果表明,港区堆场内作业源上方10~25 m处易形成PM 2.5高浓度区域;随着与污染源水平距离的增加,PM2.5浓度在距地面20~70 m有增长的趋势,且高浓度区域范围有扩大的趋势。通过PM 2.5与温度、湿度、CO2浓度、高度等4项指标的相关性分析,提出了针对港区不同区域的抑尘建议,研究结论可为港口环境评估以及综合治理提供技术支撑。
The distribution of PM 2.5 and other air pollutants in the dust of dry bulk port is the key basis of dust control.Taking Lianyungang Port dry bulk operation area as the research object,a monitoring platform based on a unmanned aerial vehicle carrying a miniature air quality detector was built to study the spatial distribution characteristics of PM 2.5 from vertical distribution and horizontal distribution dimensions.The results showed that the high concentration area of PM 2.5 was easy to form at 10-25 m above the operating source in the yard.With the increase of horizontal distance from pollution source,the concentration of PM 2.5 at a height of 20-70 m had an increasing trend,and the range of high concentration area precented a expansion trend.Through correlation analysis of PM 2.5 and four indicators,such as temperature,humidity,CO 2 concentration and height,suggestions on dust suppression for different areas of the port were put forward.The research conclusion could provide technical support for port environmental assessment and comprehensive treatment.
