摘　　要：为量化京津冀(BTH)地区超低排放(ULE)改造推广应用潜在的环境效益,基于GEOS-Chem大气化学模型,设计了2个全国情景和6个区域情景,从区域大气输送、超低排放改造在燃煤电厂(CPPs)、工业燃煤(ICB)推广及控制NH;排放等方面进行研究.结果表明:(1)全国燃煤电厂完成ULE改造,使得京津冀地区2015年1月PM_(2.5)浓度下降3.2%(2.4μg·m^(-3)),如只是京津冀地区燃煤电厂完成ULE改造,可使京津冀地区PM_(2.5)浓度降低1.1%(0.8μg·m^(-3)),可知区域联防联控对雾霾的治理具有重要意义;(2)在京津冀地区燃煤电厂完成ULE改造的基础上,工业燃煤完成ULE改造、NH;排放减少30%和50%,可使得京津冀地区PM_(2.5)浓度分别降低5.4%(3.5μg·m^(-3))、4.7%(4.0μg·m^(-3))和7.7%(5.7μg·m^(-3)),可知工业燃煤的ULE改造和NH;减排,均可显著降低PM_(2.5)的浓度;(3)在京津冀地区燃煤电厂和工业燃煤都完成ULE改造的基础上,NH;排放分别减少30%和50%,可使得PM_(2.5)浓度分别降低8.5%(6.3μg·m^(-3))和11.2%(8.3μg·m^(-3)),可知工业燃煤的ULE改造降低常规污染物或NH;减排控制均能显著降低PM_(2.5)浓度,为更好地降低京津冀地区PM_(2.5)的浓度应综合考虑工业燃煤的ULE改造、NH;减排及区域联防联控,可通过经济代价和环境效益分析确定最佳的雾霾治理方案.To quantify the potential environmental benefits of the promotion and application of ultra-low emission(ULE)transformation in the BeijingTianjin-Hebei (BTH) region,2 national scenarios and 6 regional scenarios are designed by considering regional atmospheric transport,ULE transformation in coal-fired power plants(CPPs),the promotion of industry coal burning(ICB)boilers and the control of NH;emissions,based on the GEOS-Chem atmospheric chemistry model.The results showed that:(1) The ULE of CPPs in China can reduce PM_(2.5)concentrations by 3.2%(2.4μg·m^(-3))in BHT region during the January of 2015.The ULE of CPPs only in the BTH region can reduce the PM_(2.5)concentration by 1.1%(0.8μg·m^(-3)),which means that regional transportation is of great significance to the control of haze;(2)Based on the ULE of CPPs in BTH region,The extra ULE of ICB and NH;emission reduction by 30%and 50%,which can reduce the PM_(2.5)concentrations by 5.4%(3.5μg·m^(-3)),4.7%(4.0μg·m^(-3))and7.7%(5.7μg·m^(-3)),respectively.It can be seen that the ULE of ICB and NH;emission reduction can significantly reduce the concentrations of PM_(2.5);(3)The NH;emissions reduced by 30%and 50%based on the ULE of CPPs and ICB in BTH region,which can reduce the PM_(2.5)concentrations by 8.5%(6.3μg·m^(-3))and 11.2%(8.3μg·m^(-3)),respectively.It can be seen that the ULE transformation to reduce conventional pollutants or NH;emission reduction control can significantly reduce PM_(2.5)concentrations.To better reduce the concentrations of PM_(2.5)in BTH region,comprehensive consideration should be given to the ULE of ICB,NH;emission reduction,and regional joint prevention.Meanwhile a better haze treatment plan can be determined through combining economic cost and environmental benefit analysis.
