摘要
为定量评估天津市《大气污染防治行动计划》实施的减排效益,研究依据大气污染源排放清单编制技术指南,通过梳理2013-2017年活动水平数据,分析主要防治措施的逐年减排效益,以期为大气环境管理政策决策提供重要参考。结果显示,2013-2017年天津市采取的主要防治措施对PM2.5的累计减排量为5.7万t,减排比例为52.5%;对PM10的累计减排量为10.6万t,减排比例为53.6%;对SO2的累计减排量为11.7万t,减排比例为75.2%;对NOx的累计减排量为17.8万t,减排比例为48.8%;对CO的累计减排量为65.3万t,减排比例为44.9%;对VOCs的累计减排量为7.0万t,减排比例为36.6%。PM2.5的减排主要得益于工艺污染的防治,其次是工业锅炉的防治;PM10的减排主要得益于扬尘源的防治,其次是工艺污染的防治;SO2的减排主要得益于工业锅炉的防治,其次是供暖锅炉的防治;NOx的减排主要得益于工业锅炉的防治,其次是供暖锅炉的防治;CO的减排主要得益于工业锅炉的防治,其次是工艺污染的防治;VOCs的减排主要得益于工艺污染的防治。控工艺污染和控移动源的减排比例相对较小,将是天津市下一步污染物减排潜力所在。
In order to quantitatively evaluate the emission reduction benefits of Tianjin Air Pollution Prevention and Control Action Plan, the study compiled technical guidelines based on the emission inventory of air pollution sources, and analyzed the annual emission reduction benefits of the main prevention measures by combing the activity level data for 2013-2017,which would provide important reference for policy decision of atmospheric environment management. The results showed that the main prevention measures taken by Tianjin in 2013-2017 had a cumulative reduction of PM2.5 of 57 000 tons and a reduction rate of 52.5%, and the cumulative reduction of PM10 was 106 000 tons and a reduction rate 53.6%, and the cumulative reduction of SO2 was 117 000 tons and a reduction rate 75.2%, and the cumulative reduction of NOxwas 178 000 tons and a reduction rate 48.8%, and the cumulative reduction of CO was 653 000 tons and a reduction rate 44.9%, and the cumulative reduction of VOCs was 70 000 tons and a reduction rate 36.6%. PM2.5 emission reduction was mainly due to the prevention of process pollution, followed by the prevention of industrial boilers. PM10 emission reduction was mainly due to the prevention of dust sources, followed by the prevention of process pollution. SO2 emission reduction was mainly due to the prevention of industrial boilers, followed by heating boilers. NOxemission reduction was mainly due to the prevention of industrial boilers,followed by heating boilers. CO emission reduction was mainly due to the reduction of industrial boilers prevention, followed by the prevention of process pollution. VOCs emission reduction mainly benefited from the prevention of process pollution.The proportion of pollution reduction by controlling process pollution and controlling mobile sources was relatively small,which would be the potential of Tianjin’s next pollutant emission reduction.
