    Resolutely win the battle to defend the blue sky and vigorously promote the "revolution to iron"
    my country's pursuit of comprehensive social progress must not only achieve the goal of economic development, but also protect the natural resources and environment such as the atmosphere, fresh water, ocean, land, and forests on which mankind depends for survival.
    The "Beautiful China" strategic policy put forward by the Eighteenth National Congress of the Communist Party of China insists on improving the quality of the ecological environment as the core, and promotes key progress in the fight against pollution.

     

    In order to resolutely win the goal of defending the blue sky, the government continues to implement key areas of air pollution control in autumn and winter.
    We will vigorously promote the "Railway Transfer".
    According to preliminary statistics, the national railway freight volume in 2019 increased by 7.
    25% over 2018, of which Beijing-Tianjin-Hebei increased by 26.
    2%.
    In 2020, due to the impact of the epidemic, although the volume of railway cargo transportation has increased, the growth rate has dropped to 3.
    24%.
    The effectiveness of atmospheric governance is still unstable, and the concentration of O3 emissions will rise in 2019

      2020 is the final year to win the battle to defend the blue sky.
    At present, the situation of air pollution prevention and control is still not too optimistic.
    *It was stated at a regular press conference held in October 2020: In recent years, the national air quality has continued to improve, and there has been a steady and upward trend.
    However, the effectiveness of atmospheric governance is still not stable, especially since the autumn and winter seasons, some cities Recently, there has been a pollution process again.
    Although the overall pollution degree and the scope of the impact have been reduced compared with previous years, we cannot relax our vigilance.
    In 2019, there were 452 days of severe pollution in 337 cities across the country, 183 days less than in 2018; 1,666 days of severe pollution, 88 days more than 2018.

     

      In 2019, the average proportion of good days in 337 cities in my country was 82.
    0%, of which, 16 cities had 100% good days, 199 cities had good days between 80% and 100%, and 106 cities had good days at 50%.
    Between ~80%, the proportion of good days in 16 cities is less than 50%; the average proportion of days exceeding the standard is 18.
    0%.
      According to the national interannual data on the concentration of six air pollutants in the "China Ecological and Environmental Status Bulletin", the concentration of PM10 and sulfur dioxide in 2019 decreased compared with 2018, the concentration of ozone increased compared with 2018, and the concentration of PM2.
    5, nitrogen dioxide and carbon monoxide remained the same.
    .

     

      In particular, there is a certain difference between the atmospheric pollutant ozone and the ozone layer that we usually talk about.
    Here, ozone is classified as an air pollutant because of its super-strong oxidizing properties.
    Its strong oxidizing properties participate in the chemical conversion process of various air pollutants and cause harm to humans, ecosystems, and urban construction.

     

      Except for gold and platinum, ozone has a corrosive effect on almost all metals, and ozone has a strong corrosive effect on non-metal materials.
    Low-level atmospheric ozone is one of the worst air pollutants and an important culprit in warming.
    Low-level atmospheric ozone can also cause respiratory diseases, which can cause hundreds of deaths each year.
    Low-level atmospheric ozone pollution is mainly photochemical smog formed by the reaction of pollutants discharged into the air such as automobile exhaust gas under light.
      Nowadays, in an environment where a series of national policies are intensively promulgated and driven by strong domestic market demand, my country’s air pollution control situation has achieved considerable results.
    The air control industry has shown a rapid development momentum, and air pollution control equipment is also welcome.
    This is a rare opportunity for development.
    People have gradually realized the importance and necessity of atmospheric control equipment.
    For example, the harm of industrial waste gas to human health includes both acute and chronic aspects.
    Acute hazards generally appear in industrial areas and nearby areas.

     

      Chronic hazards refer to the harm to human health caused by the direct or indirect effects of air pollutants.
    This hazard is not obvious in the short-term and is not easy to detect.
    If there is no treatment of industrial waste gas pollution treatment equipment, this situation will become more and more serious.

     

      Although the output of air pollution prevention and control equipment has declined year by year from 2016 to 2018, 2019 has ushered in a turning point.
    In 2019, the output of air pollution prevention and control equipment in China was 333,714 units (sets), an increase of 96964 units (sets) from 2018, a year-on-year increase 40.
    96%.

     

      In 2020, due to the overall economic decline due to the epidemic, under the influence of the general environment, the output of air pollution prevention and control equipment has achieved a small increase, an increase of only 0.
    93% year-on-year.
      Total exhaust gas emissions decreased by 42% from 2016-2019, of which industrial sources accounted for a large proportion

      Since the reform and opening up, my country’s economic, social and cultural fields have achieved leapfrog development.
    However, the rapid development of the economy is bound to bring certain environmental and resource problems.
    Under the influence of the extensive industrial economy, my country has been facing More severe air pollution problems.
    Regarding air pollution control, various localities have introduced policies and measures, and many industrial enterprises have also begun to try to use various types of machinery and equipment to reduce air pollution.

     

      In recent years, as my country has increased its efforts to control air pollution, the total exhaust gas emissions have been reduced year by year, from 39.
    572 million tons in 2016 to 27.
    797 million tons in 2019, a decrease of 42%.
    my country* divides the sources of air pollutants into industrial sources, living sources, mobile sources, and centralized sources.
    Industrial sources account for a large proportion.

     

      During 2016-2019, although the exhaust emissions from industrial sources are also decreasing year by year, the proportion of air pollutants from industrial sources each year is greater than the total of all other sources.

     

      Waste gas pollutants discharged from industry will also cause serious harm to our country's agriculture, forests, and aquatic products.
    Among them, agriculture and forests suffer more.
    Air pollution causes agricultural production and forest decline.
    Pollutants in industrial waste gas can not only pollute the lower atmosphere and cause harm to human health, agriculture, forests, and material materials, but also affect the upper atmosphere, causing regional and major environmental problems such as acid rain, ozone layer destruction, and temperature rise.
    It may bring more serious harm and disasters to mankind.
