摘　　要：施工扬尘是扬尘污染的重要来源,扬尘在线监测是扬尘污染监管的新手段。通过天津市扬尘在线监测试点建设工作,首次利用扬尘在线监测对各施工阶段的施工工地颗粒物排放特征及其在重污染天气时的应用进行了研究。土方开挖阶段的施工工地PM10排放浓度最高,在相继的五个施工阶段中,PM10排放浓度呈现高-低-高的趋势,对施工工地的监管应与施工周期同步;各施工阶段在春季的PM10排放浓度均为最高;施工工地夜间施工的现象较为普遍。Construction site dust is an important source of dust pollution, dust on -line monitoring is a new measure of dust pollution supervision. Through the dust On - line monitoring pilot project in Tianjin, the particulate matter emission characteristics of Construction sites in different construction phases, and the application of dust on - line monitoring in heavy pollution weather were studied for the first time. The emission concentration of PM10 in earthwork excavation is the highest, and presents the high - low -high tendency in the successive five construction phases, which means that the supervision of construction sites should be synchronous with the whole construction period. The highest emission concentration of PMlo appears in spring season at all the construction phases, and the phenomenon of night construction is general.
