摘要
基于现场采样监测法,对沥青铺路现场和沥青搅拌站开展挥发性有机物(VOCs)组分及浓度的监测,利用排放因子法对四川省17个城市的沥青铺路排放源VOCs排放量进行了计算。结果表明,摊铺过程的VOCs浓度水平为1~3mg/m^3,摊铺后浓度水平在0.1~1mg/m^3范围,在施工作业位旁瞬时样品浓度高达10mg/m^3以上。沥青搅拌站和铺路现场的主要共同物种为萘、甲苯、间对二甲苯、异丁烷;四川省17城市对应的沥青铺路排放源VOCs的排放量为0.63万t,主要的活性贡献物种为萘、间/对-二甲苯、顺-2-丁烯、1,2,4-三甲基苯、甲苯等。
Based on the field measurements,the volatile organic compounds(vocs) components and concentrations were monitored on the asphalt pavement site and in the asphalt mixing plant.The VOCs emission from asphalt pavement in 17 cities of Sichuan province was calculated by emission factor method.The results showed that the concentration level of VOCs in the paving process is 1 mg/m^3~ 3 mg/m^3,the concentration level after paving is within the range of 0.1 mg/m^3~ 1 mg/m^3,and the concentration of samples is up to more than 10 mg/m^3 at the side of the construction site.The common species of asphalt mixing plant and paving site are naphthalene,toluene,m-p-xylene and isobutane.The emission of VOCs from asphalt pavement emission sources in 17 cities in Sichuan province is 6300 tons,and the main ozone formation potential contributor species is naphthalene,m-p-xylene,cis-2-butene,1,2,4-trimethylbenzene,toluene,et al.
