Despite operational challenges, but "control" of the steel industry continues. 2012 China Steel Energy Forum organized by the Metallurgical Industry Planning Research Institute recently, the ministry sources, the Ministry of Environmental Protection has considered and adopted the eight National Pollutant steel sintered pellets industrial air pollutant emission standards " emission standards.
According to the procedure currently being countersigned by the State General Administration of Quality Supervision, Inspection and Quarantine, will soon release.
Substantial tightening of emission limits
"12th Five-Year" period, the steel industry has become one of the key objectives of the national energy saving policy control, planning for long-iron and steel industry the standards of pollutant emissions will be one by one floor.
Wuxue Fang, Ministry of Environmental Protection, director of environmental standards, new standards in general significantly tightened emission limits for particulate matter and sulfur dioxide, additional emission limits for nitrogen oxides and other pollutants; more stringent water regulations for environmentally sensitive areas and atmospheric pollutants, especially emissions limits.
According to industry sources, compared with the requirements of the existing iron and steel industry emissions of air pollutants, the new regulations add five pollutants. Compared with the existing iron and steel industry water pollutants emission standards, 14 pollutants, including 11 heavy metals and toxic pollutants in the project.
The standards clearly defined, industry-wide concentration of particulate matter emissions from the current 100-150mg/m3 adjustment for 20-50mg/m3 new iron and steel sintering machine the concentration of sulfur dioxide emissions from the current 2000mg/m3 adjustment for 200mg/m3 the additional nitrogen oxide The emission concentration of 300mg/m3. This requires that particulate matter through efficient dust removal technology governance, and sulfur dioxide can be used to govern the installation of flue gas desulfurization equipment.
At present, the existing iron and steel enterprises set emissions standards for two years, three months of the transition period, to allow enterprises to have some time to modify the equipment. Transition period, existing enterprises must implement strict emission control requirements.
It is understood that the Ministry of Environmental Protection has decided to amend the series of emission standards for iron and steel industry, set the iron mining and dressing industry emission standards, steel sintered pellets industrial air pollutant emission standards, "ironmaking industrial air pollution emissions standards, air pollutant emission standards for the steel industry, steel rolling industrial air pollutant emission standards, the ferroalloy industry emission standards ", the steel industry standards for water pollutants, and coke chemical industry pollution emissions standards. "
Pollution prevention and control situation remains grim
In recent years, the degree of attention for energy conservation and constantly enhance the pollution prevention and control work has made some progress, but the situation is still grim.
The data show that the "Eleventh Five-Year" period, China's sulfur dioxide emissions cut by 14.29%, exceeding the emission reduction mandate; significant reduction in emissions of air pollutants, including thermal power, including in key areas, the country's electricity, non-metallic mineral products ferrous metal smelting industry, sulfur dioxide emission intensity decreased by 72.5%, 58.1% and 50%; the national total of 76.83 million kilowatts of shutting down small thermal power units, eliminating backward production capacity of 120 million tons steelmaking 072 million tons, 370 million tons of cement .
During the 12th Five-Year "energy saving is still the focus of the iron and steel industrial restructuring, the state will continue to support efforts to increase energy saving. 2011 per unit of GDP energy consumption and carbon dioxide emission intensity is difficult to complete than the 2010 target, the first year of the steel industry, energy-saving goals can not be completed on schedule, the 2012 energy situation can only be even more severe. "Insiders frankly.
According to the Ministry of Environmental Protection official said, will also air pollutant emission standards for motor vehicles, industrial boilers, cement and petrochemical, and other key industries and key areas to revise substantially closing the strict emission limits.
Motor vehicles National V emission standards has been completed for Approval; cement emission standards in accordance with the deployment will be introduced this year; emission standards for industrial boilers and oil refining are also revised.
