This year is the final year of the "Three-Year Action Plan to Win the Blue Sky Defense War" that started in 2018.，It is also the starting year for the formulation of the new "14th Five-Year" air pollution control plan。Although there have been frequent measures to win the "Blue Sky Defense" in recent years，Air pollution is still not fully controlled，The cause of heavy pollution is still in doubt。Huang Runqiu, Minister of the Ministry of Ecology and Environmental Protection, stated that "the severe situation facing environmental pollution and ecological protection has not fundamentally changed"，At the same time, "the high-risk situation with frequent environmental incidents has not fundamentally changed."。

To make governance more effective in the next five years，China Green Development Council International Environmental Special Fund has analyzed the gains and losses of air pollution control in recent years，Try to find the shortcomings of air pollution control，And face the current disputes and differences in the field of smog management，We hope to make more systematic planning and more effective treatment during the "14th Five-Year Plan" air pollution control。For this purpose，Specially organized and held the "Air Pollution Precise Control (Second) Symposium"。

At the meeting，Zhou Jinfeng, Secretary General of China Green Development Council、Pan Jiahua, a researcher at the Institute of Urban Development and Environment, Chinese Academy of Social Sciences, shared his thoughts and concepts as a guest speaker，Think we need to find the real source of smog，Accurate force，Rather than relying on year after year shutdowns to maintain air quality。From Chinese Academy of Sciences、Chinese Academy of Meteorological Sciences，Experts and professors from universities and research institutes across the country、Technical experts in the field of air pollution control、Energy-saving and emission-reduction enterprise representatives，Department of Science and Technology of National Energy Administration，And Shandong、Shanxi Environment Department，Beijing、Representatives from relevant departments such as Tianjin Environment Bureau，Through online and offline synchronization，Participate together。Ma Yong, Deputy Secretary-General of the Green Association, presided over the meeting and made a summary。

He Ping, Chief Expert of Green Club International Environmental Special Fund、Wang Yuesi, Researcher, Institute of Atmospheric Physics, Chinese Academy of Sciences、Niu Tao, a researcher at the Chinese Academy of Meteorological Sciences, discussed the main issues facing current air pollution control at the meeting、Changes in atmospheric ammonia content and its impact on air pollution、Special reports on air pollution forecasting process and the impact of humidity on haze and other issues。The rest of the experts said that “condensable particles，"Aerosol and Air Pollution", "The Influence of Humidity (Water Vapor) on Air Pollution/Ammonia Emissions in the Process of Denitrification" and "Technical Solutions" to give presentations，Comments and discussions。Some technical experts also talked about "Integration of flue gas waste heat recovery and emission reduction and whitening"，"Dry Desulfurization，Innovative technical solutions such as "Non-ammonia denitrification" and "Cloud removal technology (removing condensable particles)" were introduced.。In the follow-up, the Green Club Financial Media will continue to carry out special reports on the content of the experts' speeches。

Experts at the meeting think，Air pollution control actions started in 2013，Achieved some results in the past few years，But it has encountered bottlenecks in recent years，Heavy smog weather repeats，Air quality in some areas does not rise but falls，Have to rely on large-scale shutdowns to achieve environmental targets。The important reason is the three indicators of current routine control，Smoke and dust (PM)，Sulfur dioxide (SO2) and nitrogen oxides (NOx)，Does not fully reflect the situation of air pollutants，Unconventional pollutants related to smog，Such as ammonia、Condensable particulate matter and moisture，Not under effective control，Simultaneously， We are in the process of reducing sulfur dioxide (SO2) and nitrogen oxides (NOx)，Its process produces serious side effects，Emit a lot of ammonia，Water vapor and condensable particles，Their interaction，Not only offset the effect of reducing sulfur dioxide and nitrogen oxides，And still，Under inversion conditions，Cause heavy haze。

The meeting also specially formed the "Problems and Suggestions for In-depth Control of Air Pollution in the "14th Five-Year Plan" (Discussion Draft)"，Invite participating experts to discuss，And combine relevant research results and data for analysis，Hope to form a suggestion on this，Feedback to relevant national departments，Grasp the real cause of smog，Reach a consensus as soon as possible on the causes of smog and the ways to control it，Change the long-term unhealed smog，Eliminate heavy pollution weather for our country，Contribute to the fundamental improvement of the ecological environment。
