摘要
通过调查扬子石化油品升级及原油劣质化改造项目的施工工地,估算6种常用工程机械的活动水平并建立排放清单。结果表明:表征工程机械活动水平的累计使用定额系数和年使用定额系数,200 t以下吊车最大,挖掘机次之,发电机第3;根据油耗量计算得到的污染物年排放量SO_2为1.813 t,NO_x为29.965 t,VOC为3.517 t,CO为18.840 t,PM_(10)为2.856 t,PM_(2.5)为0.494 t;由污染物排放的分担率可知,搅拌机是最大贡献源,占所调查的施工工地非道路机械排放总量的71.61%;挖掘机次之,占比为15.48%;200 t以下吊车第3,占比为8.76%。
By investigating the construction site of Yangzi Petrochemical oil upgrading project, this paper estimated the activity data of six kinds of machinery and developed emission inventory. The results of cumulative quota coefficient and annual quota coefficient showed that crane below 200 tons was the machinery with the highest activity, excavator was the second and generator was the third. The annual total emissions of SO2, NOx, VOC, CO PM10 and PM2.5 from non-road mobile machinery of this construction site were about 1.813t, 29.9651, 3.517t, 18.8401, 2.856t and 0.4941, respectively. Blender was the largest source of pollution with the contribution ratio about 71.61%; excavator was the second largest source of pollution with the contribution ratio about 15.48%; crane below 200 tons was the third largest source of pollution with the contribution ratio about 8.76%.
