关于O_(3)和PM_(2.5)协同控制的一些思考

Some Thoughts on Coordinated Control of O_(3)and PM_(2.5)

细颗粒物(PM_(2.5))和臭氧(O_(3))是影响我国环境空气质量持续改善的两个关键污染物,具有一定的同根同源性,具备协同控制的基础条件。通过对现阶段我国实施O_(3)和PM_(2.5)协同控制的政策管理、科学机理、技术措施和能力建设等方面的系统分析,建议从国家层面科学划定O_(3)联防联控区域,优化区域联防联控机制;摸清O_(3)关键前体物VOCs和NOx的排放基数,建立VOCs分物种清单;量化协同方案,有序开展污染物、区域、行业多角度协同控制;开展O_(3)和PM_(2.5)协同机理研究,强化科学研究的支撑作用;开展VOCs综合治理,提高监管执法能力建设。以期实现O_(3)和PM_(2.5)短期削峰,长期达标。

In China,PM_(2.5)and O_(3)are two key pollutants that affect the continuous improvement of the ambient air quality.At the same time,O_(3)and PM_(2.5)have a certain degree of homology,so they have the basic conditions for coordinated control.Through a systematical analysis of the policy management,scientific mechanism research,technical measures,capacity building,etc.On the coordinated control of O_(3)and PM_(2.5),it is recommended to scientifically delineate the joint prevention and control zone of ozone at the national level and optimize the regional joint prevention and control mechanism;find out the emission base of the key ozone precursors VOCs and NOx,establish the dynamic emission inventory of VOCs and NOx,and a sub-species emission inventory of VOCs;quantify the coordinated program,and carry out air pollutants,regions,and industries coordination from multiple perspectives manner in order;carry out researches on the synergistic mechanism of O_(3)and PM_(2.5),and strengthen the supporting role of scientific research;carry out comprehensive management of VOCs emission from air pollutant sources,improve monitoring and law enforcement capacity building,in order to achieve short-term peak reduction of O_(3)and PM_(2.5),and meet ambient air quality standards in long-term.
