天津市滨海新区大气污染源排放污染物特征分析

Characteristic Analysis of Pollutant Discharge from Air Pollution Sources in Binhai New Area,Tianjin

通过分析2016年滨海新区大气污染源的组成情况及污染源排放污染物情况,研究分析了污染物排放特征。其中PM 2.5和PM 10的主要排放源是扬尘源,分担率分别为33.71%、54.16%;SO 2、NO X和BC的主要排放源是非道路移动源,分担率分别为46.77%、42.23%和47.43%;CO和OC的主要排放源是固定燃烧源,分担率分别为80.3%、48%;VOCs的主要排放源是工艺过程源,分担率为61.15%;NH 3的主要排放源是农业源,分担率为90.09%。最后对滨海新区大气污染防治工作提出了针对性的防治对策和建议。

The composition of the air pollution sources in the Binhai New Area in 2016 and the emission of pollutants from the pollution sources were analyzed,and the emission characteristics of pollutants were studied and analyzed.Among them,the main sources of PM 2.5 and PM 10 emissions were dust sources,and the distribution rates were 33.71%and 54.16%,respectively.The main sources of emissions for SO 2,NO X and BC were non-road mobile sources,with a contribution rate of 46.77%,42.23%and 47.43%,respectively.The main sources of CO and OC emissions were fixed combustion sources,with distribution rates of 80.3%and 48%,respectively.The main source of emissions of VOCs was the process source,with a contribution rate of 61.15%.The main source of emissions from NH 3 was agricultural sources,with a contribution rate of 90.09%.Finally,some countermeasures and suggestions for the prevention and control of air pollution in Binhai New Area were put forward.
