To reduce or eliminate smog weather, fundamentally speaking, it is necessary to greatly reduce the emission of major pollutants. China's huge pollutant emissions will not be reduced overnight, and a single means of reducing emissions will never work. Only by taking strong and comprehensive measures at the national level can it succeed. So ... how to deal with smog management?
1, accelerate the adjustment of energy structure.
First, vigorously improve the efficient and clean utilization of coal. Coal accounts for nearly 70% of China's primary energy consumption, and it is difficult to change significantly in the short term. Therefore, efficient and clean utilization of coal is a top priority.
The second is to control the total coal consumption. All localities have formulated the implementation plan of total coal consumption, decomposed the total control targets into local governments, implemented target responsibility management, and strengthened assessment and supervision.
The third is to accelerate the development of clean energy. Vigorously develop clean energy such as hydropower, conventional natural gas, unconventional natural gas (coalbed methane and shale gas), biomass energy, wind energy, solar energy and geothermal energy, and increase the pipeline import of natural gas and liquefied natural gas.
Fourth, continue to control the development of coal chemical industry. Coal chemical industry is an industry with high energy consumption, high water consumption and high pollution, and its wastewater (high COD) and slag are extremely difficult to treat.
2. The key is to solve the problem of coal pollution.
First, all coal-fired power plants, coal-fired boilers and coal chemical plants are required to install desulfurization, denitrification and dust removal facilities. On the basis of installing desulfurization facilities in most existing independent thermal power plants, all independent thermal power plants, self-built thermal power plants, coal-fired boilers and coal chemical plants are further required to install desulfurization facilities as soon as possible. At the same time, all large coal-fired power plants, coal-fired boilers and coal chemical plants will be required to install denitration and dust removal facilities.
Second, speed up the introduction of new pollutant discharge standards for coal-fired facilities such as thermal power generation, coking, building materials and coal-fired boilers, add pollutant discharge indicators, and further tighten pollutant discharge limits. At the same time, through online monitoring, we will vigorously strengthen the inspection of pollutant discharge standards.
The third is to strengthen the operation inspection of environmental protection facilities such as desulfurization, denitrification and dust removal to ensure the normal operation of relevant environmental protection facilities and play their due role.
3. Strengthen the emission management of steel and oil refining.
Strengthen the supervision and inspection of the discharge standards of major pollutants in steel, oil refining and other industries. For the main pollutant emission sources such as sintering machine in iron and steel industry, coal-fired boiler in oil refining industry and catalytic cracking, the construction of environmental protection facilities such as desulfurization, denitrification and dust removal will be accelerated.
4. Strengthen motor vehicle pollution control.
First, improve the pricing mechanism of refined oil products as soon as possible, implement the preferential tax policies for the next phase of national oil quality standards in advance, accelerate the upgrading of refined oil quality, and implement the requirements of the Twelfth Five-Year Plan for air pollution prevention and control in key areas. Fully supply national IV gasoline before the end of 20 13; By the end of 20 14, the national IV vehicle diesel will be fully supplied.
The second is to strictly strengthen the supervision and inspection of refined oil quality, and severely crack down on the illegal production and sale of vehicle oil products that do not meet the requirements of national and local standards.
The third is to speed up the implementation of the new automobile emission standards. Implement the fourth-stage national motor vehicle emission standards, promulgate and implement the fifth-stage national motor vehicle emission standards in a timely manner, encourage qualified areas to implement the next-stage motor vehicle emission standards in advance, and greatly reduce the exhaust emissions of new vehicles entering the market. Vehicles that do not meet the national motor vehicle emission standards shall not be produced or sold.
Fourth, vigorously develop public transportation, reduce urban road congestion and reduce exhaust emissions.
The above is the "method to control smog", and everyone can also control road dust pollution. Implement mechanized cleaning of urban roads; Increase the frequency of urban road washing and cleaning, and effectively reduce the road dust load; Reduce the road excavation area and shorten the exposure time.
