| The atmosphere is one of the most basic elements of the environment for human survival. The rapid development of economy in the past 30 years in China, the industrialization and the city has begun to take shape, but more and more environmental problems happended. Coal and oil consumption, the rapid expansion of city and the amount of vehicle growth, resulted in 2/3 regions of China suffering a lot from the polluted air. Air quality has deteriorated to a threat to people’s physical and mental health. Dense population of Beijing-Tianjin-Hebei region has become one of the high incidence areas of haze.Atmospheric haze phenomenon, meteorological factors are incentives, high emissions of pollutants by human beings is the root cause. Temporal and spatial distribution of SO2, NO2, and CO were investigated by OMI, GOME2, MOPITT satellite data. In recent five years, NO2 concentration in Beijing increased, while the SO2 concentration showed a declining trend, VOCs and CO concentration were high and its interannual variation being little. According to the.source apportionment of PM2.5 by 1MB (Inventory Mass Balance) model in Beijing, the main pollutants in atmosphere is still by coal combustion, followed by motor vehicles, dust and industry. Combined with the practice of economy and society in Beijing, the shortcomings in air pollution control technologies and policie in Beijing were put forward:the unreasonable industrial structure, environmental regulation is not strictly obeyed, information is not open. Western countries (America, EU, England and Japan, etc) have taken measures to deal with the haze, their experiences is worthy of study by Beijing.The key technology of PTFE filtering device including the effects of particle concentration, filtration speed, humidification mode on particle filtering effects was studied. Emission reduction by motor vehicle including emission standards, fuel quality, old cars disposal, oil and gas recovery was investigated. Coal desulfurization and denitrification, winter heating mode change, the adjustment of energy structure, energy saving, transportation, energy conservation by construction industry and emission reduction in communication were studied, and the values of energy conservation and the reduction of air pollutants were calculated.Analysis of energy consumption of each industry in Beijing and their relationship with the emission of pollutants, as well as the adoption of foreign experience, the countermeasure and suggestion were put forward: upgrading technology and adjustment of energy structure in Beijing. Saving energy, reducing carbon dioxide emissions radically reduced PM2.5 and its precursors. The reduction of atmospheric pollutants from all industries and fields were evaluated by using emission factor method. Carbon trading in Beijing is evaluated by CGE-BJ dynamic general equilibrium model for its effect on the reduction of air pollutants. This paper put forward strategies as following for the prevention and control of atmospheric pollution in Beijing:to break the administrative boundaries, to strengthen the coordination between the government, the cooperation between the corresponding departments, strengthen law enforcement team, the introduction of third-party supervision, the use of economic means to eliminate backward production capacity, the establishment of public participation mechanism, adhere to the long-term planning and comprehensive measures.The CGE-BJ model developed in this study have been used by the Beijing municipal government on the carbon trading market, meanwhile, the proposed measures and technologieshave beenimplementedpart in the practice ofair pollution control in Beijing. This study provides scientific basis and technical support for the reduction of air pollution in Beijing and other cities. |
