How to control air pollution, 10 ways to solve air pollution?

At present, there are three ways to remove indoor air pollution in China:

One is physical adsorption: formaldehyde and other polluting substances in the air are adsorbed through activated carbon, such as activated carbon. Or actively filter the indoor air with a device equipped with activated carbon. For example: air purifiers.

Features: Activated carbon** is inexpensive but has a small adsorption range and poor effect. Air purifiers can actively absorb and filter indoor air, but they cannot remove the source of pollution and are extremely expensive.

2. Photocatalytic technology: that is, cold catalyst photocatalyst technology. Based on multi-phase catalysis, combined with ultra-fine filtration, a variety of harmful odorous gases are decomposed into harmless and odorless substances, which are transformed from simple physical adsorption to chemical adsorption, and the life of adsorption materials is more than several times that of ordinary materials, and the pertinence is relatively strong, and it can catalyze the decomposition of harmful gases such as indoor formaldehyde.

Features: Able to effectively deal with the current mainstream methods.

3. Plant suction technology: experts have developed a variety of deodorants and formaldehyde scavengers, such products generally use complexation technology, and its active ingredients are alkaloids and liquid activated carbon extracted from Chinese herbal medicines such as Lauder and Banlan root. It can effectively destroy the molecular structure of harmful gases such as formaldehyde and benzene, neutralize harmful gases in the air, and then gradually remove them, and finally achieve the purpose of improving indoor air quality.

It can effectively degrade formaldehyde.

Features: **Moderate, good removal effect. It belongs to the latest technology.

If you're referring to the air that lives in the outside world, you can only rely on plant adsorption.

First of all, reduce the source of pollution, and plant corresponding vegetation according to the type of pollution to adsorb pollution, which can improve the air, but the cycle must be very long.

1. Reasonable industrial layout to facilitate the diffusion of pollutants and the mutual use of waste gas between factories to reduce waste gas emissions.

2. Implement district central heating, replace the scattered low chimney group with high-efficiency boilers, and replace the scattered low-rise chimney emission mode with high-efficiency boilers. This is a powerful measure for the prevention and control of urban air pollution.

3. Change the fuel composition. Such as the development of urban industrial and civil gas, liquefied petroleum gas, the adoption of low-sulfur fuels and new energy (solar, wind, geothermal, etc.). Coal mining should be carried out to remove most of the sulphur (mainly pyrite sulphur) from the coal.

4. Reduce automobile exhaust emissions. The main thing is to change the combustion design of the engine and improve the combustion quality of the oil, and strengthen traffic management.

5. The toxic gases emitted by industrial plants should be controlled from the aspects of process reform and utilization.

6. Chimney dust removal. Sulfur dioxide control technology in flue gas is divided into two categories: dry method (using solid powder or particles as absorbent) and wet process (using liquid as absorbent).

1. Focus on solving the problem of environmental air pollution sources polluted by enterprises

1) Implement the planning system, the three-simultaneous system, the total control system, and the environmental impact assessment system for the control and management of pollution sources in accordance with the law;

2) The implementation of zero discharge of pollutants in the management of pollution sources is a measure to cure the root cause;

3) Vigorously carry out technological innovation, reform technology, energy conservation and emission reduction;

4) Relocation of unreasonable pollutant discharge enterprises to solve the problem of seascape air pollution affected by meteorological and regional factors that are not conducive to the dilution and diffusion of pollutants;

2. Actively solve the problem of traffic pollution of environmental air

1) No polluting exhaust emissions from motor vehicles, and vigorously solve the problem of reducing pollutants from motor vehicles;

2) Strengthen the research on the treatment technology of exhaust emissions;

3) the implementation of non-polluting motor vehicles; sprinkling water and dust reduction on traffic roads;

4) Green travel for all people, advocate walking travel, do bus travel, reduce the frequency of use of motor vehicles (odd and even number restrictions), 3, the construction industry to prevent dust, particulate matter pollution;

4. Solve the problem of indoor air pollution

1) Green decoration (the focus is on the selection of green decoration materials), less fine decoration, not excessive decoration, air quality testing, governance;

2) For the cooking fume, purification equipment should be set up and regularly tested; Home cooking should have a range hood to exhaust smoke.

3) No smoking in indoor and public places;

4) The boiler used for indoor heating should meet the emission standards.

Reduce pollutant emissions.

Reform the energy structure and adopt non-polluting energy sources (such as solar energy, wind power, hydropower) and low-pollution energy sources (such as natural gas, biogas, alcohol).

Fuel pretreatment (e.g. fuel desulfurization, liquefaction and gasification of coal) to reduce the amount of substances that pollute the atmosphere when burned.

Improvement of combustion devices and combustion technologies (e.g., reform of stoves, adoption of boiling furnaces, etc.) to improve combustion efficiency and reduce harmful gas emissions.

Adopt non-polluting or low-polluting industrial production processes (e.g., no or less use of raw materials that are easy to cause pollution, closed-loop process, etc.).

Energy conservation and comprehensive utilization of resources. Strengthen enterprise management to reduce accidental emissions and escape. Clean up and properly dispose of industrial, domestic and construction waste residue in a timely manner to reduce dust on the ground.

Treat the main pollutants emitted.

After the above-mentioned measures are taken in the combustion process and industrial production process, some pollutants are still emitted into the atmosphere, and their emission concentrations and total emissions should be controlled so that they do not exceed the environmental capacity of the area. The main methods are:

Use a variety of dust collectors to remove smoke and various industrial dusts.

Gas absorption towers are used to treat harmful gases (such as absorbing sulfur dioxide in exhaust gas with alkaline solutions such as sodium carbonate; Treatment of nitrogen oxides in exhaust smoke by alkaline absorption).

Application of other physical (e.g., condensation), chemical (e.g., catalytic conversion), physicochemical (e.g., molecular sieve, activated carbon adsorption, membrane separation) methods** to utilize useful substances in the exhaust gas, or to make harmful gases harmless.

Development of plant purification.

Plants have the functions of beautifying the environment, regulating the climate, intercepting dust, absorbing harmful gases in the atmosphere, etc., and can purify the atmosphere for a long time and continuously in a large area. Especially when the influence of pollutants in the atmosphere is wide and the concentration is relatively low, plant purification is an effective method. The planned and selective expansion of green space in cities and industrial areas is a long-term and multi-functional measure for comprehensive air pollution prevention and control.

Take advantage of the self-cleaning power of the environment.

The self-purification of the atmospheric environment has physical, chemical (diffusion, dilution, oxidation, reduction, precipitation washing, etc.) and biological effects. Under the condition that the total amount of pollutants discharged is constant, the distribution of pollutant concentrations in time and space is related to meteorological conditions, and understanding and mastering the law of meteorological changes and making full use of the self-purification ability of the atmosphere can reduce the concentration of pollutants in the atmosphere and avoid or reduce the harm of air pollution. For example, based on the aerodynamic and thermodynamic changes of the atmosphere in different regions and at different altitudes, the height of chimneys in different regions can be reasonably determined, so that the air pollutants emitted through the chimneys can be quickly diffused and diluted in the atmosphere.

There are many ways to tackle air pollution, and we have to start with the small things around us, such as driving less cars and walking more, reducing CO2 emissions, and cooking on a gas stove instead of using a charcoal fire. Reduce part of air pollution, so the way to reduce air pollution must start from the small things around you, starting from yourself, in order to achieve more ideal results.

To solve air pollution, the first thing is to find the source of pollution for treatment, and then to green, save energy and reduce emissions, which is the most effective.

Air pollution has become a common problem in countries around the world. There are more and more actions being taken on this issue, and there are small things that everyone can do to mitigate the effects of pollution. Here are 10 ways to tackle air pollution.

1.Drive less.

Driving is one of the main sources of air pollution. When your car is moving, it emits many harmful gases, such as carbon monoxide and nitrogen oxides. If you can drive less and walk more or ride a bicycle, there will be a big improvement in environmental pollution.

2.Change the way you travel.

Using public transport or car-sharing can also reduce pollution. A large number of vehicles drive through the road, which will release harmful substances into the air, causing air pollution. If more and more people use public transport, we can significantly reduce emissions.

3.Save energy.

In order to generate electricity or energy, we need to consume a lot of fossil fuels. But this behavior emits a lot of greenhouse gases. Therefore, we should minimize energy consumption and reduce water use.

For example, energy-efficient LED light bulbs and light switch timers can be used to reduce energy use.

4.Reforestation.

Planting trees is one of the most effective ways to reduce air pollution. Trees can absorb harmful gases and dust while converting carbon dioxide into oxygen.

5.Promote sustainable development.

When we use natural resources, we must be cautious, economical and protect the ecological environment and ecological balance. Sustainable development strategies help to reduce the impact and damage to the ecological environment.

6.Improve pollution control capabilities.

Widely apply modern pollution control technology, continuously strengthen the supervision of pollutant discharge settings and maximize the use of pollutants, so as to further control the discharge and management of pollutants and reduce the scope of their influence.

7.Strengthen publicity and education.

Through publicity and education, residents will be raised to understand the impact, prevention and treatment of air pollution, and a positive atmosphere will be formed for the masses to participate and consciously protect the ecological environment.

8.Strengthen environmental awareness.

People should always be environmentally conscious, choose foods and products that are good for the environment, reduce waste, and reuse. We can learn about environmental protection and use it to change our consumption habits.

9.Use clean energy.

Clean energy is a type of energy that does not produce harmful gases. For example: solar and wind energy. If we replace traditional energy sources with more clean energy, we can reduce the pressure on the environment and air pollution.

10.Support environmental organizations.

Supporting environmental organizations and actively participating in environmental protection activities allows us to better understand what environmental protection means and how to help protect the planet and human health. In addition, funding can be provided to environmental organizations to promote environmental protection.

To sum up, tackling air pollution requires not only concrete actions from countries** and environmental organizations, but also individual efforts. Through sensible, sustainable lifestyles and cleaner energy, we can make a difference for the natural environment.

1. Control the amount of drought and slow down emissions, and make use of nature's self-purification ability. According to the different meteorological conditions, the capacity of the atmosphere to pollutants is different, the concentration of pollutants discharged is different, and the pollution emitted is different.

2. Industrial and urban planning should be reasonable, and emissions should not be too concentrated. Do not discharge secondary pollution in one place, otherwise serious pollution will occur.

4. Use an air purifier. The most effective way to eliminate indoor air pollution is ventilation. In a confined space that relies on an air-conditioning system, the effective way to maintain air quality is to use an air purification device to purify the indoor air, and it is best to choose an air purification device with the function of decomposing organic pollutants, which can achieve the ideal effect of purifying the indoor air.

The first is to reduce pollutant emissions. Comprehensively renovate coal-fired small boilers, and accelerate the transformation of desulfurization, denitrification and dust removal in key industries. Remediation of urban dust. Improve fuel quality and eliminate yellow label vehicles within a time limit.

The second is to strictly control the new production capacity of high-energy-consuming and high-polluting industries, and complete the "Twelfth Five-Year Plan" backward production capacity elimination task in key industries such as steel, cement, electrolytic aluminum, and flat glass one year ahead of schedule.

The third is to vigorously promote cleaner production, and the emission intensity of major air pollutants in key industries will be reduced by more than 30% by the end of 2017. Vigorously develop public transportation.

Fourth, accelerate the adjustment of the energy structure and increase clean energy such as natural gas and coal-to-methane.

Fifth, strengthen the constraints of energy conservation and environmental protection indicators, and for projects that have not passed the energy assessment and environmental impact assessment, they shall not be approved to start construction, shall not provide land, shall not provide loan support, and shall not supply electricity and water.

Sixth, we will implement a new mechanism for energy conservation and emission reduction with both incentives and constraints, and increase the collection of sewage fees. Increase credit support for air pollution prevention and control. Strengthen international cooperation and vigorously cultivate environmental protection and new energy industries.

Seventh, use laws and standards to "force" industrial transformation and upgrading. Formulate and revise emission standards for key industries, and propose amendments to the Air Pollution Prevention and Control Law and other laws. Mandatory disclosure of environmental information of enterprises in heavily polluting industries.

Publish air quality rankings of key cities. Increase the severity of penalties for illegal acts.

Eighth, establish a joint prevention and control mechanism for the Bohai Rim, including the Beijing-Tianjin-Hebei region, the Yangtze River Delta, the Pearl River Delta and other regions, strengthen the management of PM2 5 in densely populated areas and key large cities, and build a responsibility assessment system for the atmospheric environment improvement targets of all provinces (autonomous regions and municipalities).

The ninth is to incorporate heavily polluted weather into the emergency management of local emergencies, and take measures such as limiting production and emissions of heavily polluting enterprises and restricting motor vehicles in a timely manner according to the pollution level.

Ten is to establish the whole society "breathe together, work together" code of conduct, the local government is responsible for the local air quality, the implementation of the main responsibility of enterprise pollution control, the coordination and linkage of relevant departments, advocate conservation, green consumption methods and living habits, mobilize the whole people to participate in environmental protection and supervision.
