start control defense of air pollution in Liaoning start work,, control of air pollution in Liaoning zone on May 30th morning, Liaoning held a "joint prevention and control of air pollution and the Twelfth National air quality protection work start meeting", in view of the main problems affecting the air quality of Liaoning start work, control of air pollution in Liaoning zone on May 30th morning, Liaoning held a "joint prevention and control of air pollution and the Twelfth National air quality protection work start meeting", for the major problems that affect the air quality of Liaoning, put forward ten tasks. It is understood that through the implementation of joint prevention and control of ten major projects, will strive to achieve the following goals: 2015,copy bags, all city and county level city air quality better than the national standard level two; Shenyang city in the economic zone of PM10, SO2 concentration decreased more than 10% over 2010, other city declined more than 5%; complete the five total emissions of air pollutants; atmospheric pollution source control in the full realization of discharge standards; out of more than 50% yellow cars, motor vehicle full use of the country’s four oil; Shenyang Economic Zone haze pollution control; acid rain frequency and range of precipitation acidity in Liaoning Coastal Economic Zone decreased significantly. Especially during the Twelfth National Games in Shenyang, and all the co host city of sulfur dioxide, nitrogen oxides and particulate matter than the daily average concentration of two national standards, no haze. These ten tasks are: first, the implementation of the integrated air pollution reduction project. On the basis of scientific summary of the experience of the "Yingkou city" of air pollution reduction pilot, the first in the Shenyang Economic Zone 8 cities in the formulation and implementation of special construction plan, to break the regional boundaries in the neighboring cities to promote the development of thermal power, building large-scale heat source plant, to encourage the use of industrial waste heat resources, accelerate the elimination process of small coal-fired boiler. By the end of 2012, the basic removal of the new, the expansion of thermal power plant,, heat source plant in the area of single evaporation in the area of 10 tons / hour of small coal-fired boiler. Two is the implementation of key industries desulfurization and denitrification project. By 2012, the existing thermal power units and 90 square meters above the sintering machine to achieve full desulfurization. At the same time, we will strengthen the supervision of the operation of the desulfurization facilities, and can not reach the design targets and can not be stable operation of the desulfurization facilities for rectification. By 2014, the active duty unit has not used the low nitrogen combustion technology or the low nitrogen combustion efficiency difference all carries on the low nitrogen combustion; the single capacity 200 thousand kilowatts above the active duty coal combustion unit all complete take off the NOx, the comprehensive denitrification efficiency must achieve 70%. Three is the implementation of the iron and steel industry industrial upgrading project. Integrated iron and steel industry production capacity, the implementation of mergers and acquisitions, eliminate backward production capacity, to achieve industrial upgrading. Focus on the industrial structure,bag outlet, merger and reorganization of iron and Steel Group and the relocation of the new Steel Corp Beiying Iron & Steel Group upgrading work. Four is the implementation of building materials industry comprehensive renovation project. Accelerate building materials industry backward production capacity elimination process. Focus on the cement industry to ensure that the new dry process cement production line of particulate matter emission standards. The five is to be "green" and "
