Measures to prevent air pollution

In order to develop the economy at an excessively fast pace, many areas in our country have sacrificed the environment. The most direct consequence is the emergence of various types of pollution. The smog that appears every winter is the best example of air pollution, which harms everyone's health. Now that environmental awareness is gradually increasing, the country is also vigorously combating pollution. So, what are the measures to prevent air pollution? Let’s take a look below.

Reforming the energy structure, using more pollution-free energy (such as solar energy, wind energy, and hydropower) and low-pollution energy (such as natural gas), pre-treating fuel (such as desulfurization before burning coal), and improving combustion technology can all reduce pollution emissions. In addition, before the pollutants enter the atmosphere, the use of dust and smoke removal technology, condensation technology, liquid absorption technology, recycling and treatment technology, etc. to eliminate some pollutants in the exhaust gas can reduce the amount of pollutants entering the atmosphere. Plant purification method. my country has a history of more than 3,000 years of using plant sources for disinfection and sterilization.

Different meteorological conditions will result in different capacity of the atmosphere for pollutants. The same amount of pollutants discharged will result in different pollutant concentrations. For areas and time periods with strong winds, good ventilation, strong turbulence and strong convection, the atmosphere has a strong diffusion and dilution capacity and can accept more factory and mining enterprise activities. In areas and periods of temperature inversion, the atmosphere's diffusion and dilution capacity is weak and it cannot accept more pollutants, otherwise it will cause serious air pollution. Therefore, effective control of emissions should be carried out in different regions and at different times.

3. Industrial Zone

The selection of factory sites, chimney design, urban and industrial zone planning, etc. should be reasonable, so as to avoid excessive concentration of atmospheric emissions, causing repeated and overlapping pollution, and leading to serious pollution incidents in local areas.

IV. Afforestation

Dense forests can reduce wind speed and cause large dust particles carried in the air to descend. The surface of the leaves is rough and uneven, some have fluff, and some can secrete mucus and oil, so they can absorb a lot of floating dust. The dusty leaves can continue to absorb floating dust after being washed by rain. This reciprocating process of blocking and absorbing dust can purify the air.

Implement the switch from coal to gas. At the same time, we will step up research and development of other new energy sources, such as solar energy, hydrogen fuel, geothermal energy, etc. This can also greatly reduce smoke pollution.

6. Start with yourself

Do not litter; try to take the bus or subway to reduce the use of private cars; participate more in greening activities such as tree planting; install exhaust treatment devices in private cars and use lubricants to ensure complete combustion of fuel and reduce harmful gas emissions.
